The Beneficial Effects of Nordic Walking Training Combined with Time-Restricted Eating 14/24 in Women with Abnormal Body Composition Depend on the Application Period. Nutrients 2024; 16:1413. [PMID: 38794651 PMCID: PMC11124239 DOI: 10.3390/nu16101413] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 05/02/2024] [Accepted: 05/05/2024] [Indexed: 05/26/2024] Open
Abstract
The aim of the study was to assess the impact of two lengths of Nordic walking (NW) training interventions combined with time-restricted eating (TRE) on improving body-composition parameters, lipid profiles, and levels of selected adipokines in women with elevated body mass. Overweight and obese women (n = 55, age: 21-85) were recruited. Four groups were selected: 6 weeks (SG6, n = 13) and 12 weeks intervention (SG12, n = 13); and two control groups: CON6 (n = 13) and CON12 (n = 13). The training sessions took place three times a week (60 min each) and were conducted outdoors under the supervision of a professional coach. The training intensity was determined individually. The extended NW program combined with TRE induced a significant weight reduction in SG12 by 1.96 kg (p = 0.010) and fat tissue by 1.64 kg (p = 0.05). The proposed interventions did not affect LBM, TBW [kg], VFA, and lipid profile. The LDL/HDL ratio changed with a small size effect. The leptin concentration differed between groups (p = 0.006), but not over time. For resistin, the differentiating factor was time (p = 0.019), with lower results observed after the intervention. The change in leptin concentration was negatively correlated with its baseline concentration (p = 0.025). Extended to 12 weeks, this intervention allows for an improvement in body composition. Neither 6 nor 12 weeks of training and fasting affected the lipoprotein profile. It is, therefore, indicated to recommend prolonged training protocols and to inform patients that beneficial effects will be seen only after prolonged use of training and time-restricted eating.

The Impact of a 6-Week Nordic Walking Training Cycle and a 14-Hour Intermittent Fasting on Disease Activity Markers and Serum Levels of Wnt Pathway-Associated Proteins in Patients with Multiple Myeloma. J Clin Med 2024; 13:2771. [PMID: 38792313 PMCID: PMC11121969 DOI: 10.3390/jcm13102771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 04/26/2024] [Accepted: 05/02/2024] [Indexed: 05/26/2024] Open
Abstract
Background: Multiple myeloma (MM) accounts for about 10-15% of all diagnosed hematologic malignancies and about 1-2% of all cancer cases. Approximately 80-90% of MM patients develop bone disease and the changes rarely regress. It is only possible to stop or slow their progression. A major role in bone destruction in MM is attributed to the Wnt signaling pathway, and its action can be modified by various types of interventions including training and diet. Therefore, the aim of this project was to evaluate the effects of a Nordic Walking (NW) training cycle and intermittent fasting (IF) on the levels of selected bone turnover markers associated with the Wnt pathway in patients with MM. Materials and methods: Results from 35 patients divided into training (NW and IF NW) and non-training (IF and control) groups were included in the analysis. A 6-week training cycle involving 60 min workouts 3 times a week was conducted. Body mass and composition as well as the levels of vitamin D, calcium and phosphorus, beta2-microglobulin, and albumin were examined before and after the completion of the training cycle. Markers of bone turnover were also determined: sclerostin (SOST), Dickkopf-related protein 1 (DKK-1), osteoprotegrin (OPG), osteopontin (OPN), and Tartrate-resistant acid phosphatase 5b (TRACP 5b). Results: There was no negative effect of IF or combined training and fasting on the nutritional status of the patients (the level of albumins was unchanged). Both training groups showed an increase in serum concentrations of the active metabolite of vitamin D (IF NW and NW: p = 0.001 and p = 0.022, respectively). The change in the concentration of this vitamin negatively correlated with the concentration of TRACP 5b (r = -0.413, p = 0.014). Evaluating the concentrations of markers related to bone turnover, a reduction in the concentrations of SOST (time: p = 0.026, time vs. group: p = 0.033) and TRACP 5b (time: p < 0.001, time vs. group p < 0.001) was indicated. Conclusions: The obtained results allow one to indicate the training with the poles as a safe and beneficial form of physical activity that should be recommended to patients suffering from MM. However, the results obtained in the present study are not sufficient to show the beneficial effect of IF applied without trainings.

Iron status determined changes in health measures induced by nordic walking with time-restricted eating in older adults- a randomised trial. BMC Geriatr 2024; 24:300. [PMID: 38553690 PMCID: PMC10979559 DOI: 10.1186/s12877-024-04876-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Accepted: 03/05/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND AND AIMS This study evaluated whether stored iron determines the adaptive response induced by Nordic walking (NW) training combined with 10 hours' time-restricted eating (TRE) in older adults. TRIAL DESIGN AND METHODS Twenty-four participants underwent 12-week NW training supported by 10 h of TRE. The group was divided due to baseline ferritin concentration low < 75 ng/ml (LF) and high level ≥ 75 ng/ml (HF). Body composition, physical fitness and blood collection were assessed at baseline and post-intervention. RESULTS NW + TRE induced a statistically significant decrease in ferritin levels in all participants (p = 0.01). Additionally, statistically significant intergroup differences in the LF vs. HF in the reduction of serum ferritin levels (p = 0.04) were observed. The procedure NW + TRE diminished HbA1c levels (p < 0.01) and glucose in all participants (p = 0.05). The range of HbA1c drop was more pronounced among those participants who experienced a greater decrease in the stored iron (p = 0.04, [Formula: see text]=0.17, F=4.59). Greater changes in body weight and percent of body fat were recorded in the HF group (for both p<0.01). CONCLUSION Body iron stores determine the effects of a 12-week NW + TRE intervention on serum ferritin. The changes in HbA1c are more pronounced in subjects with a higher decrease in serum ferritin. TRIAL REGISTRATION All experimental protocols were approved by the Bioethical Committee of the Regional Medical Society in Gdansk, Poland (NKBBN/330/2021) according to the Declaration of Helsinki. We confirm that all methods were carried out in accordance with relevant guidelines and regulations. The trial was registered as a clinical trial (NCT05229835, date of first registration: 14/01/2022, direct link: https://classic. CLINICALTRIALS gov/ct2/show/NCT05229835 ). Informed consent was obtained from all subjects.

The Effect of a Six-Week Nordic Walking Training Cycle on Oxidative Damage of Macromolecules and Iron Metabolism in Older Patients with Multiple Myeloma in Remission-Randomized Clinical Trial. Int J Mol Sci 2023; 24:15358. [PMID: 37895038 PMCID: PMC10607094 DOI: 10.3390/ijms242015358] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2023] [Revised: 09/17/2023] [Accepted: 10/07/2023] [Indexed: 10/29/2023] Open
Abstract
Multiple myeloma (MM) is an incurable hematologic malignancy originating from clonal plasma cell proliferation within the bone marrow, predominantly affecting older individuals. While anemia serves as a diagnostic criterion for MM, it often ameliorates upon achieving disease remission. Iron metabolism parameters have emerged as potential prognostic indicators in MM. Notably, physical exercise has been established to influence iron metabolism. This study aimed to assess alterations in serum iron, ferritin, and transferrin concentrations, as well as leukocyte gene expression, in MM patients undergoing a six-week cycle of Nordic walking training. Thirty patients divided into an exercise group (NW, n = 15, mean age 63.1 ± 8.4 years) and a control group (CG, n = 15, mean age: 63.5 ± 3.6 years) completed the study protocol. Blood samples were collected at baseline, after three and six weeks of training, and after nine weeks. Serum ferritin, transferrin, and iron concentrations were measured, along with the leukocyte expression of genes. Additionally, serum oxidative damage marker levels were determined. Following the Nordic walking training cycle, a declining trend in serum ferritin concentrations was observed. Intracellular mRNA levels of genes associated with iron metabolism were positively influenced by the training regimen, indicating the potential impact of this physical activity on gene expression and ferritin concentrations. Although positive trends were noted, extended training periods might be requisite for significant changes. To conclude, moderate-intensity exercise induces favorable shifts in the analyzed parameters among MM patients, potentially influencing disease progression. Consequently, Nordic walking training is a safe recommendation for MM patients, though sustained training beyond six weeks could be necessary for notable effects on iron metabolism factors.

Nordic Walking training in BungyPump form improves cognitive functions and physical performance and induces changes in amino acids and kynurenine profiles in older adults. Front Endocrinol (Lausanne) 2023; 14:1151184. [PMID: 37766686 PMCID: PMC10520281 DOI: 10.3389/fendo.2023.1151184] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Accepted: 08/16/2023] [Indexed: 09/29/2023] Open
Abstract
Introduction Although impacts of physical activity on cognitive functions have been intensively investigated, they are still far from being completely understood. The aim of this study was to evaluate the effect of 12 weeks of the Nordic Walking training with BungyPump resistance poles (NW-RSA) on the amino acid and kynurenine profiles as well as selected myokine/exerkine concentrations, which may modify the interface between physical and cognitive functions. Methods A group of 32 older adults participated in the study. Before and after the intervention, body composition, cognitive functions, and physical performance were assessed. Blood samples were taken before and 1 h after the first and last sessions of the NW-RSA training, to determine circulating levels of exercise-induced proteins, i.e., brain-derived neurotrophic factor (BDNF), irisin, kynurenine (KYN), metabolites, and amino acids. Results The NW-RSA training induced a significant improvement in cognitive functions and physical performance as well as a reduction in fat mass (p = 0.05). Changes were accompanied by a decline in resting serum BDNF (p = 0.02) and a slight reduction in irisin concentration (p = 0.08). Still, changes in irisin concentration immediately after the NW-RSA intervention depended on shifts in kynurenine-irisin dropped as kynurenine increased. The kynurenine-to-tryptophan and phenylalanine-to-tyrosine ratios decreased significantly, suggesting their possible involvement in the amelioration of cognitive functions. No changes of glucose homeostasis or lipid profile were found. Shifts in the concentrations of selected amino acids might have covered the increased energy demand in response to the NW-RSA training and contributed to an improvement of physical performance. Conclusion Regular Nordic Walking training with additional resistance (BungyPump) improved cognitive functions and physical performance. These positive effects were associated with a reduced BDNF concentration and kynurenine-to-tryptophan ratio as well as changes in the amino acid profile.

The Role of Increased Expression of Sirtuin 6 in the Prevention of Premature Aging Pathomechanisms. Int J Mol Sci 2023; 24:ijms24119655. [PMID: 37298604 DOI: 10.3390/ijms24119655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 05/23/2023] [Accepted: 05/29/2023] [Indexed: 06/12/2023] Open
Abstract
Sirtuins, in mammals, are a group of seven enzymes (SIRT1-SIRT7) involved in the post-translational modification of proteins-they are considered longevity proteins. SIRT6, classified as class IV, is located on the cell nucleus; however, its action is also connected with other regions, e.g., mitochondria and cytoplasm. It affects many molecular pathways involved in aging: telomere maintenance, DNA repair, inflammatory processes or glycolysis. A literature search for keywords or phrases was carried out in PubMed and further searches were carried out on the ClinicalTrials.gov website. The role of SIRT6 in both premature and chronological aging has been pointed out. SIRT6 is involved in the regulation of homeostasis-an increase in the protein's activity has been noted in calorie-restriction diets and with significant weight loss, among others. Expression of this protein is also elevated in people who regularly exercise. SIRT6 has been shown to have different effects on inflammation, depending on the cells involved. The protein is considered a factor in phenotypic attachment and the migratory responses of macrophages, thus accelerating the process of wound healing. Furthermore, exogenous substances will affect the expression level of SIRT6: resveratrol, sirtinol, flavonoids, cyanidin, quercetin and others. This study discusses the importance of the role of SIRT6 in aging, metabolic activity, inflammation, the wound healing process and physical activity.

The effects of a single and a series of Finnish sauna sessions on the immune response and HSP-70 levels in trained and untrained men. Int J Hyperthermia 2023; 40:2179672. [PMID: 36813265 DOI: 10.1080/02656736.2023.2179672] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/24/2023] Open
Abstract
BACKGROUND The aim of the study was to investigate the effect of a Finnish sauna on the immune status parameters. The hypothesis was that hyperthermia would improve immune system's functioning by changing the proportion of lymphocyte subpopulations and would activate heat shock proteins. We assumed that the responses of trained and untrained subjects would be different. MATERIAL AND METHODS Healthy men (20-25 years old) were divided into groups: the trained (T; n = 10), and the untrained group (U; n = 10). All participants were subjected to 10 baths (each one consisted of: 3 × 15-minute exposure with cooled down for 2 min. Body composition, anthropometric measurements, VO2 peak were measured before 1st sauna bath. Blood was collected before the 1st and 10th sauna bath, and 10 min after their completion to asses an acute and a chronic effect. Body mass, rectal temperature and heart rate (HR) were assessed in the same time points. The serum levels of cortisol, Il-6, HSP70 were measured with use of ELISA method, IgA, IgG and IgM by turbidimetry. White blood cells (WBC), leukocyte populations counts: neutrophils, lymphocytes, eosinophils, monocytes, and basophils were determined with use of flow cytometry as well as T-cell subpopulations. RESULTS No differences were found in the increase in rectal temperature, cortisol and immunoglobulins between groups. In response to the 1st sauna bath, a greater increase in HR was observed in the U group. After the last one, the HR value was lower in the T group. The impact of sauna baths on WBC, CD56+, CD3+, CD8+, IgA, IgG and IgM was different in trained and untrained subjects' responses. A positive correlation between the increase in cortisol concentrations and increase in internal temperatures after the 1st sauna was found in the T (r = 0.72) and U group (r = 0.77), between the increase in IL-6 and cortisol concentrations in the T group after the 1st treatment (r = 0.64), between the increase in IL-10 concentration and internal temperature (r = 0.75) and between the increase in IL-6 and IL-10 (r = 0.69) concentrations, also. CONCLUSIONS Sauna bathing can be a way to improve the immune response, but only when it is undertaken as a series of treatments.

Abstract
Vibration exercises on a platform (whole-body vibration, WBV), widely used in rehabilitation, sports medicine, and fitness, is an alternative to strength effort. The presented study assessed the effect of a 12-week cycle of vibration training on the serum concentrations of brain-derived neurotrophic factor (BDNF) and cortisol in young women (trial ID: ACTRN 12621000114842). Volunteers were assigned to three groups: performing exercises on a vibrating platform (n = 17), performing identical exercises without a platform (n = 12), and passive control group (n = 17). The concentration of BDNF and cortisol was assessed four times: before the first training session, 5 min after it, also before, and 5 min after the last training session. There were no statistically significant changes in the groups or among groups for both substances. WBV in the presented form did not increase the secretion of BDNF and is not a stressful stimulus.

Abstract
Vitamin C supplementation and exercise influence pro/antioxidative status and the cellular stress response. We tested the effects of exercise training for 6 weeks, supported by 1000 mg of vitamin C supplementation in elderly women. Thirty-six women were divided into two groups: a control group (CON) (n = 18, age 69.4 ± 6.4 years, 70.4 ±10.4 kg body mass) and a supplemented group (SUPP) (n = 18, aged 67.7 ± 5.6 years, body mass 71.46 ± 5.39 kg). Blood samples were taken twice (at baseline and 24 h after the whole period of training), in order to determine vitamin C concentration, the total oxidative status/capacity (TOS/TOC), total antioxidant status/capacity (TAS/TAC), and gene expression associated with cellular stress response: encoding heat shock factor (HSF1), heat shock protein 70 (HSPA1A), heat shock protein 27 (HSPB1), and tumor necrosis factor alpha (TNF-α). We observed a significant increase in TOS/TOC, TAS/TAC, and prooxidant/antioxidant balance in the SUPP group. There was a significant decrease in HSPA1A in the CON group and a different tendency in the expression of HSF1 and TNF-α between groups. In conclusion, vitamin C supplementation enhanced the pro-oxidation in elderly women with a normal plasma vitamin C concentration and influenced minor changes in training adaptation gene expression.

Abstract
Background: Cellulite is a cosmetic defect that affects over 80% of post-pubertal women. One of its pathomechanisms involves microvascular dysfunction. It has been suggested that vibration is a physical stimulus that may improve circulation in the skin and muscles. The aim of this study was to evaluate the effect of local vibration on cutaneous microcirculation and on eliminating the symptoms of cellulite in women. Methods: A total of 57 healthy women with at least grade 1 cellulite were recruited and divided into four groups differing by treatment time (30′ or 60′) and position (sitting or lying) during the vibration treatments. Participants took part in 15 vibrotherapy sessions. Body composition, selected circumferences, cellulite grade, and thermographic images of buttocks and thighs were recorded. Results: Significant changes in skin temperature were observed in both studied areas after the first and last treatments in each group. A significant decrease in cellulite grade was observed after a series of treatments. The strongest effects were observed for the sitting position with a treatment time of 60 min. Conclusion: Vibration treatment improves microcirculation in cellulite-affected areas. Over time, no adaptation was observed, and subsequent treatments maintained the beneficial effects. Extending the treatment time increased its influence on the microcirculation in the skin.

Abstract
BACKGROUND Several inflammatory dermatoses, including dermatomyositis (DM), may present as erythematous papules or plaques on the dorsal aspects of the hands over the joints. Limited skin involvement in these entities may pose a diagnostic challenge. (Video)dermoscopy is being utilized more frequently to aid in differential diagnosis of inflammatory skin conditions. OBJECTIVE To describe the dermoscopic findings in Gottron's papules and compare with dermoscopic features of other dermatoses involving the dorsal aspects of the hands. METHODS Videodermoscopic images from patients presenting with erythematous papules or plaques on the dorsal surface of the hands were retrospectively analyzed for the presence of standardized dermoscopic parameters. RESULTS Dermoscopic images from patients with DM (n=12), psoriasis (n=19), chronic dermatitis (n=16), mycosis fungoides (n=7), lichen planus (n=5) and pityriasis rubra pilaris (n=3) were included. Gottron's papules were characterized by pleomorphic vessels (dotted vessels accompanied by thick or thin linear vessels with branches or linear curved vessels) in 66.7% of cases, arranged in unspecified pattern (91.7%), and accompanied by white or pink structureless areas (75.0%). Psoriatic plaques were characterized by dotted vessels arranged in a uniform pattern (94.7%). Vessels arranged in a ring pattern were nearly exclusively observed in psoriasis, while yellow structureless areas and erosions were more frequently present in chronic dermatitis. White lines, corresponding to Wickham striae, were specific for lichen planus. CONCLUSIONS Videodermoscopy might be of value in differentiating Gottron's papules from other dermatoses involving dorsa of the hands.

Fasting and Exercise Induce Changes in Serum Vitamin D Metabolites in Healthy Men. Nutrients 2021; 13:nu13061963. [PMID: 34201027 PMCID: PMC8226906 DOI: 10.3390/nu13061963] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 05/29/2021] [Accepted: 06/04/2021] [Indexed: 01/19/2023] Open
Abstract
Background: Vitamin D plays pleiotropic roles in the body and hence, changes in its metabolism and distribution during starvation could play an important role in the adaptive response to famine. We aimed to identify the responses of some vitamin D metabolites to 8 d of fasting and exercise. Methods: A repeated-measures design was implemented, in which 14 male volunteers fasted for 8 d and performed an exercise test before and after fasting. Serum samples were collected on day 1 after night fasting and after 8 d of complete food restriction, before and 1 h and 3 h after exercise. Results: After 8 d of fasting, compared with baseline values, serum 24,25(OH)2D3 and 3-epi-25(OH)D3 levels significantly increased; those of 25(OH)D3 and 1,25(OH)2D3 were unaffected; and those of 25(OH)D2 decreased. Exercise on the first day of fasting induced an increase in serum 3-epi-25(OH)D3 levels, while exercise performed after 8 d of fasting induced an increase in 25(OH)D3, 24,25(OH)2D3, 25(OH)D2, and 3-epi-25(OH)D3 levels. Conclusion: Increases in 24,25(OH)2D3 and 3-epi-25(OH)D3 levels imply that fasting stimulates vitamin D metabolism. The effects of exercise on serum vitamin D metabolites, which are most pronounced after fasting and in subjects with serum 25(OH)D3 above 25 ng/mL, support the notion that fasting and exercise augment vitamin D metabolism.

Effect of six weeks 1000 mg/day vitamin C supplementation and healthy training in elderly women on genes expression associated with the immune response - a randomized controlled trial. J Int Soc Sports Nutr 2021; 18:19. [PMID: 33653365 PMCID: PMC7923494 DOI: 10.1186/s12970-021-00416-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Accepted: 02/16/2021] [Indexed: 12/24/2022] Open
Abstract
Background In this study, we investigated the effects of supplementation and exercise on the expression of genes associated with inflammation like CCL2, CRP, IL1, IL6, IL10 mRNA in elderly women. Methods Twenty four participants divided randomly into two groups were subjected to 6 weeks of the same health training program (three times per week). SUP group (supplemented, n = 12, mean age 72.8 ± 5.26 years and mean body mass 68.1 ± 8.3 kg) received 1000 mg of Vitamin C/day during the training period, while CON group (control, n = 12, mean age 72.4 ± 5.5 years and body mass 67.7 ± 7.5 kg) received placebo. Results No significant changes in IL-1, IL-6, IL-10 and CRP mRNA were observed within and between groups. However, there was a clear tendency of a decrease in IL-6 (two-way ANOVA, significant between investigated time points) and an increase in IL-10 mRNA noted in the supplemented group. A significant decrease in CCL2 mRNA was observed only in the CON group (from 2^0.2 to 2^0.1, p = 0.01). Conclusions It can be concluded, that 6 weeks of supplementation and exercise was too short to obtain significant changes in gene expression in leukocytes, but supplementation of 1000 mg vitamin C positively affected IL-6 and IL-10 expression – which are key changes in the adaptation to training. However, changes in body mass, IL1 and CCL2 were positive in CON group. It is possible that Vitamin C during 6 weeks of supplementation could have different effects on the expression of individual genes involved in the immune response. Trial registration Retrospectively registered.

Abstract
Objectives: In obesity, there is a shift in the pro-oxidative-antioxidant balance towards the oxidationreactions. However, it has been shown that in people with normal body composition, after a series of whole-body cryotherapy (WBC), the balance shifts in the opposite direction. Design: The aim of the study was to assess the impact of 20 WBC treatments on blood pro-oxidative-antioxidant balance. Interventions: Study included 14 obese (BMI > 35) and 10 non-obese volunteers. Methods: The total antioxidative (TAS/TAC) and pro-oxidative status (TOS/TOC) in serum and activity of antioxidant enzymes in erythrocytes were determined before the first and 2 hours after the last cryostimulation. Results: In the obese group, a significantly higher level of TOS/TOC, and its significant decrease after the WBC series, was observed. Cryotherapy had no influence on TAS/TAC level which was similar in both groups. Changes in activity of antioxidant enzymes were multidirectional. An increase in CAT activity in the obese group was observed. OSI, both before and after a series of treatments, was significantly higher in obese subjects. Conclusions: A beneficial effect on the level of TOS/TOC and CAT activity was indicated, but the proposed number of treatments for patients with class II obesity turned out to be insufficient.

Eight Days of Water-Only Fasting Promotes Favorable Changes in the Functioning of the Urogenital System of Middle-Aged Healthy Men. Nutrients 2020; 13:nu13010113. [PMID: 33396948 PMCID: PMC7824351 DOI: 10.3390/nu13010113] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2020] [Revised: 12/16/2020] [Accepted: 12/29/2020] [Indexed: 12/03/2022] Open
Abstract
The aim of this study was to determine whether, after 8 days of water-only fasting, there are changes in the efficiency of the lower urinary tract, the concentration of sex hormones, and the symptoms of prostate diseases in a group of middle-aged men (n = 14). For this purpose, before and after 8 days of water-only fasting (subjects drank ad libitum moderately mineralized water), and the following somatic and blood concentration measurements were made: total prostate specific antigen (PSA-T), free prostate specific antigen (PSA-F), follicle stimulating hormone (FSH), luteotropic hormone (LH), prolactin (Pr), total testosterone (T-T), free testosterone (T-F), dehydroepiandrosterone (DHEA), sex hormone globulin binding (SHGB), total cholesterol (Ch-T), β-hydroxybutyrate (β-HB). In addition, prostate volume (PV), volume of each testis (TV), total volume of both testes (TTV), maximal urinary flow rate (Qmax), and International Prostate Symptom Score (IPSS) values were determined. The results showed that after 8 days of water-only fasting, Qmax and IPSS improved but PV and TTV decreased significantly. There was also a decrease in blood levels of PSA-T, FSH, P, T-T, T-F, and DHEA, but SHGB concentration increased significantly. These results indicate that 8 days of water-only fasting improved lower urinary tract functions without negative health effects.

Abstract
BACKGROUND Lichen planus (LP) is an inflammatory condition that can affect skin, mucous membranes, hair follicles, and/or nails. Nail abnormalities are estimated to occur in around 10% of LP cases. Clinical characteristics of nail involvement have been the subject of very few studies, which have mainly focused on isolated nail LP. OBJECTIVES To identify and describe nail alterations in patients with LP. METHODS Seventy-five patients with cutaneous lichen planus (CLP) were included in the study. The diagnosis of LP was histologically confirmed in each case. Onychomycosis was excluded in each patient. RESULTS Nail lesions were present in 21 (28%) patients (mean age 58.1 ± 12.55 years) with CLP. On an average, patients had 9.38 nails affected. A slight female preponderance was noted (57%). Nail involvement was independent of age, gender, presence of pruritus, the affected skin area, or the duration of CLP. The most common finding in the fingernails (n = 122) was longitudinal ridging (85.2%), followed by nail plate thinning (38.2%) and onycholysis (17.2%). Pterygium formation (6.6%) and red lunulae (8.2%) were limited to the fingernails. In the fingernails, matrix involvement (98.4%) was more frequent than nail bed involvement (27%). The most common finding in the toenails (n = 75) was hyperkeratosis (82.7%) with yellowish discoloration (69.3%). No cases of trachyonychia or anonychia were noted. CONCLUSIONS Nail abnormalities in patients with CLP may be more common than initially assessed. Rare formation of pterygium and absence of anonychia in patients with predominant cutaneous involvement might point at mild course of the nail disease in such cases.

[PMID: 33319363 DOI: 10.1111/ijd.15365] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/20/2020] [Revised: 11/14/2020] [Accepted: 11/20/2020] [Indexed: 12/12/2022]
Abstract
BACKGROUND Discoid lupus erythematosus (DLE) may lead to disfiguring scarring and permanent hair loss. Dermoscopy may serve as a noninvasive tool useful in the preliminary diagnosis of hair loss and inflammatory skin diseases. The aim of the paper was to summarize and analyze the dermoscopic features of DLE lesions in various anatomical locations. METHODS A systematic review of PubMed, Scopus and Web of Science was performed using the search terms: 'lupus' OR 'discoid lupus' OR 'cutaneous lupus' combined with 'dermoscopy' OR 'dermatoscopy' OR 'videodermoscopy' OR 'videodermatoscopy' OR 'trichoscopy' OR 'mucoscopy' OR 'onychoscopy'. RESULTS About 29 out of 318 initially identified papers were included in the analysis. In scalp DLE (n = 166), the most common findings were: white structureless areas (62%), arborizing vessels (57.8%), white scales (54.2%), follicular keratotic plugs (47%), absent follicular openings (45.8%), perifollicular scaling (43.9%), pink-white background (40.4%), speckled brown pigmentation (38%), and fibrotic white dots (33.7%). In non-scalp DLE (n = 129), the most frequent features were: follicular keratotic plugs (66.7%), white perifollicular halo (65.9%), white scale (39.5%), speckled brown pigmentation (38.8%), white structureless areas (37.2%), and arborizing vessels (34.9%). There are scarce data in the literature on dermoscopic findings in labial (n = 8), mucosal (n = 3) and ungual DLE (n = 1). CONCLUSIONS DLE is characterized by a wide variety of dermoscopic findings with variable frequencies depending on the location of the lesions. Nevertheless, further studies are needed in order to reliably assess frequencies, correlation with disease stage and significance of individual dermoscopic features.

Comparison of the impact of childhood psoriasis on mothers' and fathers' quality of life - does gender of a caregiver play a role? J Eur Acad Dermatol Venereol 2020; 35:685-692. [PMID: 32915485 DOI: 10.1111/jdv.16930] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 08/21/2020] [Indexed: 11/29/2022]
Abstract
BACKGROUND Psoriasis is a chronic skin condition that in one third of cases starts in the first two decades of life. The disease might impact the quality of life (QoL) of the affected children and their caregivers. The issue of gender differences in the assessment of psychological burden of dermatological conditions has been the subject of few studies with contradictory results. OBJECTIVES The aim of this study was to investigate the differences in the impact of childhood psoriasis on mothers' and fathers' well-being using Family Dermatology Life Quality Index (FDLQI). METHODS Forty-five children with psoriasis (31 girls and 14 boys; mean age ± standard deviation (SD) 10.53 ± 3.44 years) and their parents (45 mothers and 45 fathers) were included in the study. Both parents of each child were asked to separately fill in the validated Polish version of the FDLQI questionnaire. RESULTS Comparing the FDLQI scores, the QoL of mothers was significantly more impaired than the QoL of fathers (13.44 ± 6.46 versus 9.53 ± 6.12 points; P < 0.0001). In mothers, childhood psoriasis had a significantly greater impact in the areas of emotional distress (P = 0.007), dealing with other people's reactions (P < 0.0001), social life (P = 0.02), amount of time spent caring for the child's skin (P = 0.0001) and extra housework (P = 0.0005), compared to fathers. The FDLQI scores of both mothers and fathers were independent of the impairment of children's QoL or the severity of psoriasis, except for positive correlation between mothers' FDLQI scores and children's BSA (R = 0.31; P = 0.03). CONCLUSIONS Differences in the impact of childhood skin diseases on mothers' and fathers' well-being should be taken into consideration while developing educational programmes for patients and their families. There is a need for further, multi-centre research that would take into account geographical and cultural differences, in order to reliably assess the impact of childhood psoriasis on various aspects of caregivers' QoL.

Exercise Training and Vitamin C Supplementation Affects Ferritin mRNA in Leukocytes without Affecting Prooxidative/Antioxidative Balance in Elderly Women. Int J Mol Sci 2020; 21:ijms21186469. [PMID: 32899447 PMCID: PMC7554744 DOI: 10.3390/ijms21186469] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2020] [Revised: 08/30/2020] [Accepted: 09/01/2020] [Indexed: 12/24/2022] Open
Abstract
Physical training and antioxidant supplementation may influence iron metabolism through reduced oxidative stress and subsequent lowering of mRNA levels of genes that are easily induced by this stress, including those responsible for iron homeostasis. Fifteen elderly women participated in our 12-week experiment, involving six weeks of training without supplementation and six weeks of training supported by oral supplementation of 1000 mg of vitamin C daily. The participants were divided into two groups (n = 7 in group 1 and n = 8 in group 2). In group 1, we applied vitamin C supplementation in the first six weeks of training, while in group 2 during the remaining six weeks of training. In both phases, the health-related training occurred three times per week. Training accompanied by vitamin C supplementation did not affect prooxidative/antioxidative balance but significantly decreased ferritin heavy chain (FTH) and ferritin light chain (FTL) mRNA in leukocytes (for FTH mRNA from 2^64.24 to 2^11.06, p = 0.03 in group 1 and from 2^60.54 to 2^16.03, p = 0.01 in group 2, for FTL mRNA from 2^20.22 to 2^4.53, p = 0.01 in group 2). We concluded that vitamin C supplementation might have caused a decrease in gene expression of two important antioxidative genes (FTH, FTL) and had no effect on plasma prooxidative/antioxidative balance.

No evidence for association between cutaneous lichen planus and hepatitis B and C virus infection in south Poland - a case-control study. Int J Dermatol 2020; 59:698-703. [PMID: 32307713 DOI: 10.1111/ijd.14880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Revised: 03/11/2020] [Accepted: 03/21/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND The incidence of hepatitis C virus (HCV) infection among patients with lichen planus (LP) varies considerably. Currently, there is more evidence for the association between hepatitic C and oral LP (OLP) than cutaneous LP (CLP). There is also lack of data on the Polish population. The study aimed at assessing the prevalence of HCV infection and liver test abnormalities among patients with CLP in south Poland. METHODS Eighty-four patients with CLP and 130 patients with other dermatoses (controls) were included in this retrospective case-control study. Medical records were reviewed for the presence of anti-HCV antibodies and hepatitis B surface antigen (HBsAg) and serum levels of liver function tests: aspartate aminotransferase (AST), alanine aminotransferase (ALT), and gamma-glumatyltranspeptidase (GGT). RESULTS Anti-HCV antibodies were not found in any of the patients in the study or control group. HBsAg was detected in one (1.19%) patient with CLP and none of the controls. Considering the prevalence of abnormal liver function parameters, there were no statistically significant differences in the frequencies of AST (P = 0.87), ALT (P = 0.9), and GGT (P = 0.81) above the upper limit between patients with CLP and patients with other dermatoses. CONCLUSIONS Currently, there is no evidence confirming the relationship between HCV infection and CLP in southern Poland. There is also no increased incidence of liver function abnormalities compared to patients with other dermatoses. However, there is a need for further research on larger groups of patients.

Abstract
In recent years, the prevalence of obesity has increased dramatically and has become a 21st century epidemic. Obesity is associated with the development of many diseases, and therefore treatments that can reduce body mass are actively sought. The aim of this study was to examine the effect of 20 cryostimulation sessions on body composition in obese/high body mass (HBM, n = 12) males and normal body mass (NBM, n = 9) controls. The HBM group had a mean age = 29.08 ± 4.19 years, body fat percentage = 32.08 ± 6.16%, body mass index = 36.23 ± 8.13 kg/m2) and NBM group had a mean age = 22.00 ± 2.45 years, body fat percentage = 12.14 ± 4.93%, body mass index = 23.58 ± 2.00 kg/m2. Kilocalorie intake was similar for both groups. All participants received 20 sessions of systemic cryostimulation at -120°C for 2-3 min in a cryochamber. Blood samples were collected before the first session, 1 h after the 10th session, and 1 h after the 20th cryostimulation session. C-reactive protein (CRP) plasma concentrations, and expression of the heat shock protein genes (HSPA1A, HSPB1) and CRP mRNA in leukocytes were evaluated after 10 and 20 cryostimulation sessions. In both groups, 20 sessions were associated with a significant decrease in body mass, fat mass and the percentage of body fat. CRP concentrations were significantly higher in obese people before the first session and after 10 treatments, but not at the end of study. Expression of HSPA1A and HSPB1 mRNA gradually decreased with the number of cryostimulation sessions. A significant difference in HSPA1A expression was found after 20 sessions (NBM > HBM) and for HSPB1 at baseline and after 20 sessions (HBM > NBM). Our results show that cryostimulation influences body composition and that cryostimulation-induced HSP genes expression depends on the number of cryosessions and baseline body mass, and is differentially altered in HBM individuals. Further research on the interaction between body mass and cold adaptation is warranted.

Abstract
Iron is essential for physical activity due to its role in energy production pathways and oxygen transportation via hemoglobin and myoglobin. Changes in iron-related biochemical parameters after physical exercise in athletes are of substantial research interest, but molecular mechanisms such as gene expression are still rarely tested in sports. In this paper, we evaluated the mRNA levels of genes related to iron metabolism (PCBP1, PCBP2, FTL, FTH, and TFRC) in leukocytes of 24 amateur runners at four time points: before, immediately after, 3 h after, and 24 h after a marathon. We measured blood morphology as well as serum concentrations of iron, ferritin, and C-reactive protein (CRP). Our results showed significant changes in gene expression (except for TFRC), serum iron, CRP, and morphology after the marathon. However, the alterations in mRNA and protein levels occurred at different time points (immediately and 3 h post-run, respectively). The levels of circulating ferritin remained stable, whereas the number of transcripts in leukocytes differed significantly. We also showed that running pace might influence mRNA expression. Our results indicated that changes in the mRNA of genes involved in iron metabolism occurred independently of serum iron and ferritin concentrations.

Abstract
It is a well known, that the physical activity promotes mental health. Physically active people relatively rarely suffer from psychosomatic and depressive disorders. It is possible that the differences in gene activity in peripheral blood leukocytes may be associated with depression, especially genes participating in inflammatory response. Thus, the aim of our study was to investigate the levels of IL6 and IL10 mRNA and IL10/IL6 ratio in peripheral blood leukocytes in healthy, physically active individuals.
One hundred healthy young men (20-23 years old) participated in this study. All of them declared regular physical activity. Participants were non-smokers, and consumed alcohol occasionally. To access genes expression, 2 ml of venous blood was collected. RNA isolation was performed and then the relative expression of IL6 and IL10 was calculated using quantitative real-time polymerase chain reaction (Q-RT-PCR). Pro and anti-inflammatory balance was calculated as 2^relative of IL10/ 2^relative expression of IL6.
Low expression of tested genes was found in healthy young men. Mean expression for IL6 was 2^0.051 (n=90) and for IL10 2^0.08 (n=98). Mean ratio IL10/IL6 was 2^1.58.
Higher expression of IL10 compared to IL6 may be essential not only for the physical performance but also for the mental health. Diverse reports in the literature may be associated with choosing various control groups, i.e. sedentary or older individuals. It is possible, that measuring the expression of IL6 and IL10 (especially the ratio IL10/IL6) in peripheral blood leukocytes may be useful in the assessment of depressive disorders. Thus, molecular study of active young men can confirm the need for physical activity among people suffering from depression, but further studies are needed, particularly among people with psychosomatic disorders.

Abstract
INTRODUCTION Some studies have shown the influence of Qigong on gene expression in different cells, but there is little data associated with the influence of this kind of therapy on genes expression in pheripheral monocellucar blood cells. OBJECTIVE The aim of this study was to evaluate changes in the expression of genes associated with cellular stress response in peripheral mononuclear blood cells (PMBC) in healthy women. MATERIAL AND METHODS The experiment took place at the Japanese Martial Arts Centre "DOJO" in Stara Wieś, Poland, conducted over the course of a 4-day qigong training session. To evaluate the genes effect of this training, blood samples were taken before and after the training period. This experiment involved 20 healthy women (aged 56.2±9.01, body height 164.8±6.5 and mass 65.5±8.2). To determine the expression of HSF-1, HSPA1A, NF-kB, IL10 and CCL2 mRNA, 3 ml of venous blood was collected. The blood samples were placed in tubes allowing for separation (BD Vacutainer CPT TM) before and after the 4 days of qigong training. Isolated PMBC were used to determine gene expression using real-time qRT-PCR (quantitative reverse transcription polymerase chain reaction). RESULTS Significant decreases in NF-kB and CCL2 mRNA and increases in IL10, HSF1 and HSPA1A m-RNA were detected after 4 days of qigong training. The obtained findings suggest that qigong caused a reduction in the inflammatory and intensified anti-inflammatory gene expression, as well as a higher expression of HSF-1 and HSPA1A. CONCLUSIONS The adaptive response to qigong training was similar to the adaptive response to physical activity and was detected through gene expression in PMBC. Furthermore, this kind of training is especially indicated for women because of their higher susceptibility to psychosocial stress when compared to men.

Abstract
OBJECTIVES The objective of the study was to reveal morphology, electrolyte and chosen biochemical parameters in terms of health risk in runners in reference to their age and running speed in the case of running a distance of 100 km, which occur after 12 h or 24 h of recovery. MATERIAL AND METHODS Fourteen experienced, male, amateur, ultra-marathon runners, divided into two age and two speed groups took part in the 100-km run. Blood samples for analyses indexes were collected from the ulnar vein just before the run, after 25 km, 50 km, 75 km and 100 km, as well as 12 h and 24 h after termination of the run. RESULTS The sustained ultramarathon run along with the distance covered (p < 0.05) caused an increase in myoglobin (max 90-fold), bilirubin (max 2.8-fold) and total antioxidant status (max 1.15-fold), which also continued during the recovery. Significant changes in the number of white blood cells were observed with each sequential course and could be associated with muscle damage. The electrolyte showed changes towards slight hyperkalemia, but no changes in natrium and calcium concentrations. There were no significant differences between the age and speed groups for all the parameters after completing the 100-km run as well as after 12 h and 24 h of recovery. CONCLUSIONS Considering changes in blood morphology and chosen biochemical parameters in ultra-marathon runners during a 100-km run it can be stated that such an exhausting effort may be dangerous for human health due to metabolic changes and large damage to the organs. Negative metabolic changes are independent of age of an ultramarathon runner and occur both in younger (32±5.33 years) and older participants (50.56±9.7 years). It can be concluded that organ damage and negative metabolic changes during a 100-km run occur similarly in participants less experienced as well as in well trained runners.

Abstract
Objective. The aim of the study was determination of the level in expression genes associated with cell stress response in a patient with PTSD. Case study. A 57-year-old PTSD patient, A.P., was the subject of the study. Blood samples were taken from the ulnar vein to assess the relative expression of the tested genes in leukocytes via a quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results. A considerably decreased level in the expression HSF-1, NF-kB, Hif-1 and IL6 m-RNA was observed in the patient when compared to the control group. A low expression in HSPA1A, HSPB1, IL10 and CRP m-RNA compared with the control group was also noted. Conclusion. It is possible that the lower level of transcriptional factors: HSF-1, NF-kB and Hif-1 as well as IL6 m-RNA may be associated with the effect of the PTSD patient's treatment.

Objectives The aim was to compare the effect of upper and lower body high-intensity exercise on chosen genes expression in athletes and non-athletes. Method Fourteen elite male artistic gymnasts (EAG) aged 20.6 ± 3.3 years and 14 physically active men (PAM) aged 19.9 ± 1.0 years performed lower and upper body 30 s Wingate Tests. Blood samples were collected before, 5 and 30 minutes after each effort to assess gene expression via PCR. Results Significantly higher mechanical parameters after lower body exercise was observed in both groups, for relative power (8.7 ± 1.2 W/kg in gymnasts, 7.2 ± 1.2 W/kg in controls, p = 0.01) and mean power (6.7 ± 0.7 W/kg in gymnasts, 5.4 ± 0.8 W/kg in controls, p = 0.01). No differences in lower versus upper body gene expression were detected for all tested genes as well as between gymnasts and physical active man. For IL-6 m-RNA time-dependent effect was observed. Conclusions Because of no significant differences in expression of genes associated with cellular stress response the similar adaptive effect to exercise may be obtained so by lower and upper body exercise.

Changes in the acid-base balance and lactate concentration in the blood in amateur ultramarathon runners during a 100-km run. Biol Sport 2015; 32:261-5. [PMID: 26424931 PMCID: PMC4577565 DOI: 10.5604/20831862.1163372] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2014] [Revised: 04/13/2014] [Accepted: 02/02/2015] [Indexed: 12/11/2022] Open
Abstract
The aim of this study was to analyse the acid-base balance and partial pressure of blood gases of participants during a 100-km run. Fourteen experienced amateur ultramarathon runners (age: 43.36±11.83 years; height: 175.29±6.98 cm; weight: 72.12±7.36 kg) completed the 100-km run. Blood samples were taken before the run; after 25, 50, 75, and 100 km; and 12 and 24 hours after the run. There were significant differences (p<0.05) between the mean values registered for acid-alkaline balance, buffering alkalies, and current bicarbonate in each segment of the run, especially during the third, fourth, and fifth segments of the run (i.e., between 50 and 100 km), and there were only significant differences associated with buffering alkalies and current bicarbonate during the recovery. However, all the changes were within the physiological norm. A significant decrease in the compressibility of oxygen was observed after 100 km (from 92.80±15.67 to 88.36±13.71 mmHg) and continued during the recovery to 75.06±8.60 mmHg 12 h after the run. Also there was a decrease in saturation to a mean value of 93.78±3.10 at 12 h after the run. Generally the amateurs runners are able to adjust their running speed so as not to provoke a significant acid-base imbalance or lactate acid accumulation.

Effects of 6-week specific low-intensity training on selected aerobic capacity parameters and HSPA1A, HSPB1, and LDHb gene expression in high-level rowers. GENETICS AND MOLECULAR RESEARCH 2015.

Abstract
The aim of this study was to demonstrate the effects of 6-week low-intensity training on changes in indicators of aerobic capacity and on HSPA1A, HSPB1, and LDHb expression in white blood cells in high level rowers. We hypothesized that the type of training would have an impact not only on the adaptation of athletes to the aerobic nature of the exercises, but also on the expression of genes, designated during exercises "until refusal". Nine Polish lightweight male rowers (21.8 ± 3.77 years of age, 74.2 ± 1.7 6 kg, 184.8 ± 4.58 cm) of high level participated in the experiment. To determine the anaerobic threshold (AnT) and peak oxygen uptake (VO2max) at the beginning and end of the 6-week training period, the subjects performed the test "till exhaustion", with increasing load. Directly before and after the test, blood samples were collected from the ulnar vein for isolation of RNA. Consecutively, reverse transcription and real time polymerase chain reaction amplification was performed. A significant influence of applied training on physiological parameters such as VO2max (P = 0.0001), AnT (W/AT) (P = 0.0007), and maximal acid lactate concentration (P = 0.018) as well as on HSPA1A expression (P = 0.0129) in rowers were detected. The 6-week low-intensity aerobic training significantly affected the physiological parameters and HSPA1A expression in the rowers. Therefore, we suggest that the response of leukocytes by activating HSPA1A was dependent on the type of training. The 6-week period proved sufficiently long to of adapting leukocytes in athletes to high intensity exercises.

Damage to Liver and Skeletal Muscles in Marathon Runners During a 100 km Run With Regard to Age and Running Speed. J Hum Kinet 2015; 45:93-102. [PMID: 25964813 PMCID: PMC4415847 DOI: 10.1515/hukin-2015-0010] [Citation(s) in RCA: 34] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/30/2023] Open
Abstract
The purpose of this study was to determine: (1) whether damage to liver and skeletal muscles occurs during a 100 km run; (2) whether the metabolic response to extreme exertion is related to the age or running speed of the participant; (3) whether it is possible to determine the optimal running speed and distance for long-distance runners' health by examining biochemical parameters in venous blood. Fourteen experienced male amateur ultra-marathon runners, divided into two age groups, took part in a 100 km run. Blood samples for liver and skeletal muscle damage indexes were collected from the ulnar vein just before the run, after 25, 50, 75 and 100 km, and 24 hours after termination of the run. A considerable increase in alanine aminotransferase (ALT) and aspartate aminotransferase (AST) was observed with the distance covered (p < 0.05), which continued during recovery. An increase in the mean values of lactate dehydrogenase (LDH), creatine kinase (CK) and C-reactive protein (CRP) (p < 0.05) was observed with each sequential course. The biggest differences between the age groups were found for the activity of liver enzymes and LDH after completing 75 km as well as after 24 hours of recovery. It can be concluded that the response to extreme exertion deteriorates with age in terms of the active movement apparatus.

Vitamin C, A and E supplementation decreases the expression of HSPA1A and HSPB1 genes in the leukocytes of young polish figure skaters during a 10-day training camp. J Int Soc Sports Nutr 2015; 12:9. [PMID: 25722659 PMCID: PMC4342201 DOI: 10.1186/s12970-015-0069-8] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2014] [Accepted: 01/16/2015] [Indexed: 12/02/2022] Open
Abstract
Background Overexpression of HSPA1A and HSPB1 has been shown to indicate stress and the degradation of damaged proteins. Therefore, the expression of these genes is often evaluated during exercise. Vitamin supplementation in young athletes may affect the expression of these genes, and help to maintain health and improve the effects of training. Methods Fourteen top junior female athletes (age 14–15y ± 0.3 SD, body mass 51 kg ± 5 SD, and BMI of 20.15 ± 0.9 SD, time in professional training 8.5 y ± 0.5 SD) attended a conditioning camp that included meals planned by a team dietitian. To examine the effects of vitamin supplementation on antioxidant status we supplemented the athletes with either vitamin A (16 ug/kg/day), vitamin C (8 mg/kg/day) and vitamin E (1 mg/kg/day) or an inert placebo. Blood samples were taken before and after (12 h post) the camp to assess the relative expression of HSPA1A and HSPB1 mRNA in leukocytes via quantitative reverse transcription polymerase chain reaction (qRT-PCR). Results Overall, participants trained ~135 min daily (1345 min total). No statistically significant differences in HSPA1A and HSPB1 expression were observed between the groups before the camp. In the unsupplemented group, there was a non-statistically significant increase in HSPA1A expression (100% change) and a significant increase (37% change, p < 0.05) in HSPB1 expression over the study period. The supplemented group experienced a significant decrease in HSPA1A (40% change, p = 0.01) and HSPB1 (25% change p = 0.03) expression over the study period. Conclusion Our results indicate that supplementation with antioxidant vitamins decreases HSPA1A and HSPB1 mRNA expression in leukocytes, and thereby may reduce exercise-induced stress in young athletes, not only during training, but also in sports competitions.
