Abstract
ABSTRACT Cornejo-Daza, PJ, Sánchez-Valdepeñas, J, Rodiles-Guerrero, L, Páez-Maldonado, JA, Ara, I, León-Prados, JA, Alegre, LM, Pareja-Blanco, F, and Alcazar, J. Vastus lateralis muscle size is differently associated with the different regions of the squat force-velocity and load-velocity relationships, rate of force development, and physical performance young men. J Strength Cond Res 38(3): 450-458, 2024-The influence that regional muscle size and muscle volume may have on different portions of the force-velocity (F-V) and load-velocity (L-V) relationships, explosive force, and muscle function of the lower limbs is poorly understood. This study assessed the association of muscle size with the F-V and L-V relationships, rate of force development (RFD) and maximal isometric force in the squat exercise, and vertical jump performance via countermovement jump (CMJ) height. Forty-nine resistance-trained young men (22.7 ± 3.3 years old) participated in the study. Anatomical cross-sectional area (ACSA) of the vastus lateralis (VLA) muscle was measured using the extended field of view mode in an ultrasound device at 3 different femur lengths (40% [distal], 57.5% [medial], and 75% [proximal]), and muscle volume was estimated considering the VLA muscle insertion points previously published and validated in this study. There were significant associations between all muscle size measures (except distal ACSA) and (a) forces and loads yielded at velocities ranging from 0 to 1.5 m·s -1 ( r = 0.36-0.74, p < 0.05), (b) velocities exerted at forces and loads ranging between 750-2,000 N and 75-200 kg, respectively ( r = 0.31-0.69, p < 0.05), and (c) RFD at 200 and 400 milliseconds ( r = 0.35-0.64, p < 0.05). Proximal and distal ACSA and muscle volume were significantly associated with CMJ height ( r = 0.32-0.51, p < 0.05). Vastus lateralis muscle size exhibited a greater influence on performance at higher forces or loads and lower velocities and late phases of explosive muscle actions. Additionally, proximal ACSA and muscle volume showed the highest correlation with the muscle function measures.

Abstract
BACKGROUND Declining physical performance in old age is associated with a wide range of negative health-related outcomes. However, it is unclear which physical capabilities should be prioritized to obtain prognostic information in older adults. AIMS To examine the associations between the performance on several physical function tests and falls, disability, and death in a well-characterized sample of very old Italian adults. METHODS This was a prospective cohort study of older adults who lived in the mountain community of the Sirente geographic area in Central Italy. Physical performance was assessed using isometric handgrip strength (IHG), walking speed (WS) at a usual and fast pace, 5-time sit-to-stand test (5STS), and sit-to-stand power measures. Appendicular skeletal muscle mass was estimated from calf circumference using a validated equation. History of falls, incident falls, and disability status according to basic Activities of Daily Living (ADLs) were recorded over two years. Survival status was obtained from the participants' general practitioners and was confirmed by the National Death Registry over 10 years from enrolment. Linear, binary, and Cox regressions were performed to evaluate the association between physical performance measures and health outcomes. RESULTS The mean age of the 255 participants was 84.2 ± 5.1 years, and 161 (63.1%) were women. Logistic regression indicated that IHG was significantly associated with incident ADL disability, whereas specific sit-to-stand muscle power was an independent predictor of death. No significant associations were observed between physical function and falls. CONCLUSIONS Our findings indicate selective associations between physical function tests and the occurrence of negative events in very old adults, with poor IHG predicting disability and specific sit-to-stand muscle power being longitudinally associated with death.

Abstract
This study investigated the associations of sarcopenic obesity (SO) with muscle strength and physical performance in sufficiently active older adults. Data from 72 older sarcopenic obese adults classified as sufficiently active were analyzed. Participants were categorized into four groups based on sex and SO status. Muscle strength/physical performance tests were compared using independent sample t-tests. Multiple linear regression and binary logistic regression were performed to examine the associations between SO and muscle strength and physical performance, adjusting for confounding variables. Only handgrip strength showed differences between SO groups, regardless of sex (p < 0.05). SO negatively explained the variability of handgrip strength (p < 0.05). An increase in handgrip strength values was associated with a decrease in the chances of older adults being classified as SO (p < 0.05). The findings suggest that even with SO, sufficiently active older adults did not present a significant reduction in muscle strength in the lower limbs and physical performance.

Abstract
PURPOSE To analyze the associations between pain and physical performance in different aging contexts. METHODS Data from 1725 older adults from Canada, Brazil, Colombia, and Albania from the 2014 wave of the IMIAS were used to assess the associations between Back Pain (BP) or Lower Limb Pain (LLP) and physical performance by the Short Physical Performance Battery (SPPB). Three binary logistic regression models adjusted for sex, age, study site, education, income sufficiency, BMI, depressive symptoms, and chronic conditions were used to estimate the associations between LLP or BP and SPPB. The SPPB was classified into good performance (8 points or more) and poor physical performance (< 8 points). RESULTS The mean age of the older men was 71.2 (± 3.0) and the mean age of the women was 71.2 (± 2.8) years. Older men (72.8%, p < 0.05) and women (86.1%, p-value < 0.05) from Albania had the highest frequencies of self-reported general pain. Older women in Colombia had the highest frequencies of LLP or BP (33.5%, p-value < 0.05). In the fully adjusted logistic regression model, LLP or BP was significantly associated with poor SPPB (OR = 0.48, 0.35 to 0.66 95% CI, p < 0.01). CONCLUSIONS Pain symptoms are associated with reduced physical performance in older people, even when adjusted for other clinical and sociodemographic factors. Protocols for aiming to increase the level of physical activity to manage pain should be incorporated into health care strategies.

Abstract
OBJECTIVE The purpose of this case series was to observe physical performance changes following an 8-week nonlinear periodization training program on firefighters currently on light duty who were cleared to participate in full physical activities. METHODS Two firefighters underwent an 8-week nonlinear periodization program. Participant 1 was returning from anterior cruciate ligament reconstruction and participant 2 from a non-surgical low back injury. The Incumbent Physical Ability Test (IPAT), 2-minute push-up test, 300-yard shuttle, and Gerkin protocol testing were assessed at baseline, week 4, and week 8. OUTCOMES Both participants demonstrated improvement in assessments of physical performance and fitness across each assessment point, with exception of the Gerkin protocol, and were able to return to full duty at the conclusion of their rehabilitation training program. CONCLUSION The physical demands of tactical professionals such as firefighters exceed those of the general population. As such, these individuals require both job-specific programming and assessments when transitioning from an injury to full duty. An 8-week nonlinear periodization program yielded improvements in performance of firefighting tasks and physical fitness in two firefighters returning to full duty after injury and highlighted effective interprofessional collaboration between the physical therapy and fitness team.

Abstract
Academy soccer players frequently train in the evening (i.e. 1700-2000 h), hence limited time to nutritionally prepare and recover due to schooling, travel and sleep schedules. Accordingly, we assessed timing and quantity of energy intake in the pre-training and post-training period. Over a 3-day in-season training period, male players (n=48; n=8 from under (U) 12, 13, 14, 15/16, 18 and 23 players) from an English Premier League academy self-reported dietary intake and physical activity levels (via the remote food photography method and activity diary, respectively) in the four hours pre- and post-training. Timing of pre-training energy intake ranged from 40 ± 28 mins (U15/U16 players) to 114 ± 71 mins (U18) before training and mean carbohydrate (CHO) intake ranged from 0.8±0.4 g.kg-1 (U23) to 1.5±0.9 g.kg-1 (U12). Timing of post-training energy intake ranged from 39 ± 27 mins (U14) to 70 ± 84 mins (U23) and mean CHO intake ranged from 1.6±0.8 g.kg-1 (U12) to 0.9±0.5 g.kg-1 (U14). In contrast to CHO, all age groups consumed sufficient protein intake in the post-training period (i.e. > 0.3 g.kg-1). We conclude academy soccer players habitually practice sub-optimal fuelling and recovery strategies, the consequence of which could impair growth, maturation and physical performance.

Abstract
BACKGROUND We aimed to investigate whether foot function and physical performance differ between women with and without bilateral painful hallux valgus (HV). METHODS Forty-four women with bilateral painful HV and forty-three controls were included. The Foot Function Index, American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Joints Scale, and Manchester-Oxford Foot Questionnaire were used. The time while walking 10 m-walkway at maximum speed and ascending and descending ten stairs as fast as possible also single-limb stance time were measured. RESULTS All self-reported and performance-based measures showed that women with HV had poorer foot function and physical performance than controls (p < 0.05). Women with mild HV had better self-reported foot function than those with moderate HV or severe HV (p < 0.05), but physical performance did not differ (p > 0.05). CONCLUSIONS Women with bilateral painful HV exhibited poorer self-reported foot function and performance-based physical function than those without HV. LEVELS OF EVIDENCE Level III.

Abstract
Sarcopenia is characterized by skeletal muscle quantitative and qualitative alterations. A marker of collagen turnover, procollagen type III N-terminal peptide (P3NP), seems to be related to those conditions. This study aims to assess the predictive role of P3NP in muscle density and physical performance changes. In the InCHIANTI study, a representative sample from the registry lists of two towns in Tuscany, Italy, was recruited. Baseline data was collected in 1998, and follow-up visits were conducted every 3 years. Out of the 1453 participants enrolled at baseline, this study includes 1052 participants. According to P3NP median levels, population was clustered in two groups; 544 (51.7%) of the 1052 subjects included were classified in the low median levels (LM-P3NP); at the baseline, they were younger, had higher muscle density, and performed better at the Short Physical Performance Battery (SPPB), compared to the high-median group (HM-P3NP).LM-P3NP cases showed a lower risk to develop liver chronic diseases, CHF, myocardial infarction, and osteoarthritis. HM-P3NP levels were associated with a longitudinal reduction of muscle density, and this effect was potentiated by the interaction between P3NP and leptin. Moreover, variation in physical performance was inversely associated with high level of P3NP, and directly associated with high fat mass, and with the interaction between P3NP and muscle density. Our data indicate that P3NP is associated with the aging process, affecting body composition, physical performance, and clinical manifestations of chronic degenerative age-related diseases.

ABSTRACT Robinson, L, Murray, A, Ehlert, A, Wells, J, Jarvis, P, Turner, A, Glover, D, Coughlan, D, Hembrough, R, and Bishop, C. Effects of physical training and associations between physical performance characteristics and golf performance in female players: A systematic review with meta-analysis. J Strength Cond Res 37(12): e646-e655, 2023-The aims of this systematic review were to assess the association between physical performance and measures of golf performance, and the effects of physical training on measures of golf performance, in female golfers. A systematic literature search was conducted in PubMed, SPORTDiscus, Medline, and CINAHL. Inclusion criteria required studies to (a) have conducted a physical training intervention of any duration in female players and determine the effects on measures of golf performance, (b) determine the association between physical performance in at least one test and golf performance in female players, and (c) be peer-reviewed and published in English language. Methodological quality was assessed using a modified version of the Downs and Black Quality Index tool, and heterogeneity was examined through the Q statistic and I2 . Pooled effect sizes were calculated using standardized mean differences (SMDs) (with 95% confidence interval [CI]s) within a random-effects model, with Egger's regression test used to assess small study bias (inclusive of publication bias). Of the 2,378 articles screened, only 9 were included in the final review, with 3 of these being associative by design and 6 being training interventions. From an associative standpoint, clubhead speed (CHS) was reported in all 3 studies and was associated with measures of strength ( r = 0.54), lower-body power ( r = 0.60), upper-body power ( r = 0.56-0.57), and flexibility ( r = 0.52-0.71). When assessing the effects of physical training interventions, CHS was again the most commonly reported golf outcome measure ( n = 5). The random-effect model indicated that CHS significantly improves within each training group following training interventions (SMD = 0.73 [95% CIs: 0.32-1.14], Z = 3.50, p < 0.001), with trivial heterogeneity ( I2 = 0.00%, Q = 0.18; p = 0.9963) and no prevalence of small study bias depicted through the Egger's regression test ( z = -0.28, p = 0.78). From the available research, it seems that CHS can be positively affected from strength, power, and flexibility training interventions. From an associative standpoint, only 3 studies have been conducted solely in female players, with one showcasing questionable methodology. Future research should aim to carefully select test measures which better represent the physical capacities needed for the sport when determining the effects of and relationships with golf performance.

Abstract
BACKGROUND Lower limb muscle power is positively associated with functional performance and patient-reported outcomes (PROMs) and suggested as an important variable to evaluate in patients with advanced knee osteoarthritis (OA). OBJECTIVES To explore the association between muscle power derived from the 30-sec sit-to-stand test (STS power) with functional performance and PROMs compared to maximal isometric knee extensor strength (KE MVC) in male- and female patients with advanced OA. STUDY DESIGN Cross-sectional design. METHODS Eighty-six patients (66.6 [64.9-67.7]years) with advanced knee OA were included. Dependent variables were STS power and KE MVC. Independent variables were Timed Up&Go (TUG), 40-m fast-paced walk test (40mFWT), Knee injury and Osteoarthritis Outcome Score (KOOS) subscales. COVARIATE Age. ANALYSES Simple linear- and multiple regression analyses with and without adjusting for age. Pitman's test was used to evaluate differences in correlation strength among dependent variables. RESULTS STS power demonstrated a statistical relationship with TUG and 40mFWT for both sexes (β coefficients -1.11 to -4.36 (p < 0.05), r2 = 0.47-0.55 (p < 0.05)), and with KOOS Pain, ADL, and Sport for male patients (β coefficients 6.53 to 7.17 (p < 0.05), r2 = 0.29-0.33 (p < 0.05)). Knee extensor MVC demonstrated no relationship with any outcomes for male patients or female patients. STS power displayed statistically stronger correlation to functional performance. CONCLUSION STS power was associated with functional performance in both male patients and female patients suffering from advanced knee OA. Moreover, STS power was associated with KOOS Pain, Sport, and ADLin male patients. The assessment of STS power should be considered in the evaluation of patients with advanced knee OA.

Abstract
INTRODUCTION Our aim was to evaluate the association between polypharmacy and certain physical performance measures used to assess ambulation in early-stage Alzheimer patients. MATERIALS AND METHODS This cross-sectional study was conducted in the dementia outpatient clinic of a tertiary care center. The usage of five or more drugs per day was accepted as polypharmacy and patients with moderate and severe dementia were excluded. Usual gait speed (UGS), timed up and go (TUG), and chair sit-to-stand test (CSST) were applied to assess physical performance status. RESULTS There were 134 participants in our study (67.9% female, mean age 80.2 ± 7.9 years) and 75 (56%) patients were polypharmacy patients. The patients with polypharmacy showed poor physical performance compared to the patients without polypharmacy (UGS p = .005, TUG p < .001, CSST p < .001). The parameters that were significantly higher and more common in the polypharmacy group were body mass index (p = .026), hypertension (p = .013), diabetes mellitus (p = .018), ischemic heart disease (p < .001), atrial fibrillation (p = .030), depression (p = .012), and hypothyroidism (p = .007). In multivariate analyses, polypharmacy was independently associated with slow UGS [Odds ratio (OR) 1.248 (95%) confidence interval (CI) 1.145-1.523, p = .007]; long TUG [OR 1.410 (95%) CI 1.146-1.736, p = .001]; and long CSST [OR 1.892 (95%) CI 1.389-2.578, p < .001]. CONCLUSION Our study demonstrated the association of polypharmacy with poor physical performance in patients with early stage Alzheimer's disease. Prospective long-term studies investigating the relationship of polypharmacy and drug subgroups with physical performance in elderly patients with Alzheimer's disease would be appropriate.

Abstract
OBJECTIVE Long-term consequences after COVID-19 include physical complaints, which may impair physical recovery and quality of life. DESIGN We assessed body composition and physical ability in patients 12 months after COVID-19. Consecutively recruited patients recovering from mild to severe COVID-19 were assessed using bioelectrical impedance analysis, 6-min-walk test, additional scales for physical performance and health-related quality of life. RESULTS Overall physical recovery was good (i.e., Glasgow Outcome Scale-Extended ≥7 in 96%, Modified Rankin Scale ≤1 in 87%, Eastern Cooperative Oncology Group ≤1 in 99%). Forty-four percent of the 69 patients experienced a significant body mass index increase in the year after COVID-19 (≥1 kg/m 2 ), whereas skeletal muscle mass index was reduced in only 12%. Patients requiring intensive care treatment ( n = 15, 22%) during acute COVID-19 more often had a body mass index increase ( P = 0.002), worse 6-min-walk test-performance ( P = 0.044), and higher body fat mass ( P = 0.030) at the 1-yr follow-up when compared with patients with mild ( n = 22, 32%) and moderate ( n = 32, 46%) acute COVID-19. Body mass index increase was also more frequent in patients who had no professional rehabilitation ( P = 0.014). CONCLUSIONS Although patients with severe COVID-19 had increased body mass index and body fat and performed worse in physical outcome measures 1 yr after COVID-19, overall physical recovery was satisfying. Translating these findings to variants beyond the Alpha strain of severe acute respiratory syndrome coronavirus 2 virus needs further studies.

OBJECTIVE To investigate up-to-date evidence of the effectiveness of neural mobilisation techniques compared with any type of comparator in improving pain, function, and physical performance in people with musculoskeletal pain. DATA SOURCES The following sources were consulted: PubMed, Web of Science, CENTRAL, CINAHL, Scopus, and PEDro databases; scientific repositories; and clinical trial registers. The last search was performed on 01/06/2023. METHODS Two reviewers independently assessed the studies for inclusion. We included randomised, quasi-randomised, and crossover trials on musculoskeletal pain in which at least one group received neural mobilisation (alone or as part of multimodal interventions). Meta-analyses were performed where possible. The RoB 2 and the Grading of Recommendations Assessment, Development and Evaluation tools were used to assess risk of bias and to rate the certainty of evidence, respectively. RESULTS Thirty-nine trials were identified. There was a significant effect favouring neural mobilisation for pain and function in people with low back pain, but not for flexibility. For neck pain, there was a significant effect favouring neural mobilisation as part of multimodal interventions for pain, but not for function and range of motion. Regarding other musculoskeletal conditions, it was not possible to conclude whether neural mobilisation is effective in improving pain and function. There was very low confidence for all effect estimates. CONCLUSIONS Neural mobilisation as part of multimodal interventions appears to have a positive effect on pain for patients with low back pain and neck pain and on function in people with low back pain. For the other musculoskeletal conditions, results are inconclusive.

Wiese KR, Ambegaonkar JP, Martin J. Impact of Attentional Focus on Dance Performance: A Critically Appraised Topic. J Sport Rehabil 2024; 33:128-134. [PMID: 37758260 DOI: 10.1123/jsr.2023-0047] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2023] [Revised: 08/11/2023] [Accepted: 08/17/2023] [Indexed: 10/03/2023]
Abstract
CLINICAL SCENARIO Dancing is a demanding esthetic activity with dancers having an 85% annual injury incident rate when performing complex dance motor skills. Teachers and clinicians use a combination of external and internal attentional cues when teaching dancers motor skills and when working on rehabilitation programs with injured dancers, respectively. External attentional focus (ie, focusing on movement outcome) reportedly results in superior performance than internal attentional focus (ie, focus on body movements). Interestingly, dancers reportedly often adopt an internal focus when dancing. Still, limited literature exists examining the effects of attentional focus on dancers' performance. CLINICAL QUESTION How does attentional focus (external or internal) impact performance in dancers? SUMMARY OF KEY FINDINGS Four original quasi-experimental studies met inclusion criteria. In the current examination, we found mixed results about the impact of attentional focus in dancers. Specifically, using an external attentional focus resulted in better performance in 2 studies, but these findings were limited to lesser experienced dancers. Experienced dancers did not have any physical performance differences when using external or internal focus. Internal focus also did not negatively affect dancers' performance in 2 studies. Some authors noted positive motivational effects (eg, increased perceived competence) when dancers used external focus. CLINICAL BOTTOM LINE Low-quality evidence exists supporting the notion that in less experienced dance students, external focus improves performance. In experienced dancers, the type of attentional focus did not impact performance. External focus provides positive mental effects. Thus, clinicians working with dancers can integrate individualized feedback according to dancer level, with a preference toward external focus due to positive mental effects, to design optimal training and rehabilitation programs. STRENGTH OF RECOMMENDATION Grade B evidence exists supporting the notion that an external attentional focus improves performance in less experienced dance students and also has positive mental effects. Internal attentional focus does not impede experienced dancers' performance.

Abstract
OBJECTIVE The objective of this review is to synthesize the effects of nutritional counseling compared with no intervention (maintaining lifestyle habits) or nutritional counseling in combination with other interventions (eg, nutritional supplementation, physical activity) on physical performance and muscle strength in older adults. INTRODUCTION Nutritional counseling, which is considered the first line of nutrition therapy, could play an important role in geriatric care programs by helping older adults understand the importance of nutrition and by promoting healthy, sustainable eating habits. However, the effects of nutritional counseling on physical function and muscle strength among older adults are not clear. INCLUSION CRITERIA This review will consider randomized controlled trials and non-randomized controlled trials. Participants aged 65 years or older, who have received nutritional counseling alone or in combination with another intervention (eg, nutritional supplementation, physical exercise) will be considered for inclusion. Comparators will include another intervention or no intervention, but physical performance (ie, gait, endurance, balance) or muscle strength must be measured. METHODS This systematic review will be conducted in accordance with the JBI methodology for systematic reviews of effectiveness. The databases to be searched will include MEDLINE (Ovid), Embase, CENTRAL (Ovid), CINAHL (EBSCOhost), and Scopus. Sources of unpublished studies and gray literature will include Google Scholar and protocol registers. Two independent reviewers will select relevant studies, critically appraise the studies, and extract data. Studies will be pooled in a statistical meta-analysis or presented in narrative format. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach will be used to grade the certainty of the evidence. REVIEW REGISTRATION PROSPERO CRD42022374527.

Abstract
OBJECTIVE The relationship between depressive symptoms and declining physical performance in postmenopausal women has been extensively examined. However, various confounding factors can influence this association. This study aimed to investigate the link between depressive symptoms and physical performance in postmenopausal women while considering potential interfering factors. METHODS In this cross-sectional study, 137 postmenopausal women were categorized into two groups based on the presence of depressive symptoms (n = 58; mean ± SD age, 60.12 ± 8.45 y) and absence of depressive symptoms (n = 79; mean ± SD age, 60.72 ± 7.45) using the Geriatric Depression Scale (short version) (GDS-15). Thoracic kyphosis angle was measured using the flexicurve method. Physical performance was assessed through various tests, including Timed Up and Go, Five Times Stand and Sit Test, 6-minute Walking Speed, 10-meter Usual Walking Speed, 10-meter Fast Walking Speed, and dynamometry. The study compared variables between the two groups and used linear regression models adjusted for dynamometry, kyphosis angle, age, antidepressant usage, sitting time, and fall history to evaluate the relationship between GDS-15 scores and physical performance. RESULTS Significant differences were observed in physical performance, body mass index, kyphosis angle, antidepressant usage, sitting time, and fall history between women with and without depressive symptoms. The GDS-15 showed a negative association with all walking speed tests (10-meter Usual Walking Speed, m/s; P < 0.001; B = -0.01; 10-meter Fast Walking Speed, m/s; P < 0.001; B = -0.02; 6-minute Walking Speed, m/s; P < 0.004; B = -0.01) and a positive association with the Five Times Stand and Sit Test ( P < 0.002; B = 0.21) and Timed Up and Go ( P < 0.001; B = 0.13) tests, regardless of grip strength, kyphosis angle, age, antidepressant use, sitting time, or fall history in postmenopausal women. CONCLUSIONS This study underscores the independent and substantial impact of depressive symptoms on the physical performance of postmenopausal women. These findings emphasize the importance of addressing both mental health and physical well-being when providing care and support for this demographic.

Abstract
BACKGROUND The relationship between amino acids, B vitamins, and their metabolites with D3-creatine (D3Cr) dilution muscle mass, a more direct measure of skeletal muscle mass, has not been investigated. We aimed to assess associations of plasma metabolites with D3Cr muscle mass, as well as muscle strength and physical performance in older men from the Osteoporotic Fractures in Men cohort study. METHODS Out of 1 425 men (84.2 ± 4.1 years), men with the lowest D3Cr muscle mass (n = 100), slowest walking speed (n = 100), lowest grip strength (n = 100), and a random sample (n = 200) serving as a comparison group to the low groups were included. Metabolites were analyzed using liquid chromatography-tandem mass spectrometry. Metabolite differences between the low groups and random sample and their relationships with the muscle outcomes adjusted for confounders and multiple comparisons were assessed using t-test/Mann-Whitney-Wilcoxon and partial correlations, respectively. RESULTS For D3Cr muscle mass, significant biomarkers (p < .001) with ≥10% fold difference and largest partial correlations were tryptophan (Trp; r = 0.31), kynurenine (Kyn)/Trp; r = -0.27), nicotinamide (Nam)/quinolinic acid (Quin; r = 0.21), and alpha-hydroxy-5-methyl-tetrahydrofolate (hm-THF; r = -0.25). For walking speed, hm-THF, Nam/Quin, and Quin had the largest significance and fold difference, whereas valine (r = 0.17), Trp (r = 0.17), HKyn/Xant (r = -0.20), neopterin (r = -0.17), 5-methyl-THF (r = -0.20), methylated folate (r = -0.21), and thiamine (r = -0.18) had the strongest correlations. Only hm-THF was correlated with grip strength (r = -0.21) and differed between the low group and the random sample. CONCLUSIONS Future interventions focusing on how the Trp metabolic pathway or hm-THF influences D3Cr muscle mass and physical performance declines in older adults are warranted.

Sensor-Based Assessment of Time-of-Day-Dependent Physiological Responses and Physical Performances during a Walking Football Match in Higher-Weight Men. SENSORS (BASEL, SWITZERLAND) 2024; 24:909.

Abstract
Monitoring key physiological metrics, including heart rate and heart rate variability, has been shown to be of value in exercise science, disease management, and overall health. The purpose of this study was to investigate the diurnal variation of physiological responses and physical performances using digital biomarkers as a precise measurement tool during a walking football match (WFM) in higher-weight men. Nineteen males (mean age: 42.53 ± 12.18 years; BMI: 33.31 ± 4.31 kg·m-2) were engaged in a WFM at two different times of the day. Comprehensive evaluations of physiological parameters (e.g., cardiac autonomic function, lactate, glycemia, and oxygen saturation), along with physical performance, were assessed before, during, and after the match. Overall, there was a significant interaction (time of day x WFM) for mean blood pressure (MBP) (p = 0.007) and glycemia (p = 0.039). Glycemia decreased exclusively in the evening after WFM (p = 0.001), while mean blood pressure did not significantly change. Rating of perceived exertion was significantly higher in the evening than in the morning (p = 0.04), while the heart rate recovery after 1 min (HRR60s) of the match was lower in the evening than in the morning (p = 0.048). Overall, walking football practice seems to be safe, whatever the time of day. Furthermore, HRR60, glycemia, and (MBP) values were lower in the evening compared to the morning, suggesting that evening exercise practice could be safer for individuals with higher weight. The utilization of digital biomarkers for monitoring health status during WFM has been shown to be efficient.

The Effect of Whole-Body Electromyostimulation Program on Physical Performance and Selected Cardiometabolic Markers in Obese Young Females. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:230. [PMID: 38399518 PMCID: PMC10890563 DOI: 10.3390/medicina60020230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/24/2023] [Revised: 01/17/2024] [Accepted: 01/25/2024] [Indexed: 02/25/2024]
Abstract
Background and Objectives: Whole-body electromyostimulation is under investigation as a potential aid for obesity-related health problems, supplementing a comprehensive, evidence-based obesity management strategy that includes lifestyle, diet, and exercise. The study investigated the impact of a whole-body electromyostimulation training program on physical performance and cardiometabolic markers in young obese females. Materials and Methods: Twenty-eight obese females, aged over 18 years with BMI over 30 and body fat over 28% and no underlying health conditions or medication, were divided into a whole-body electromyostimulation group (15 participants) and a control group (13 participants). The whole-body electromyostimulation program lasted 12 weeks, with two 20 min sessions weekly, using bipolar, rectangular current. Assessments pre and post intervention included body composition, blood pressure, lipid profile, C-reactive protein levels, maximal oxygen consumption, and jumping and sprint performance. Two-way ANOVA and t-tests were used for analysis. Results: Statistical analysis revealed significant (group × time) interactions for body composition, systolic blood pressure, maximal oxygen consumption, jumping and sprint performance, and plasma levels of lipids and C-reactive protein. Post hoc analyses for the whole-body electromyostimulation group indicated improvements in body composition indices (p < 0.01), systolic blood pressure (p = 0.003), maximal oxygen consumption (p = 0.010), and both jumping and 30 m sprint performance (p < 0.001 and p = 0.001, respectively) after the intervention. Furthermore, plasma levels of lipids (p < 0.01) and C-reactive protein (p = 0.002) showed significant improvements following the training program. In contrast, no significant changes were observed for these variables in the control group. Conclusions: A 12-week whole-body electromyostimulation program significantly improved body composition (skeletal muscle mass, body mass index, body fat, and waist circumference), physical performance (maximal oxygen consumption, jumping and sprint performance), and certain cardiometabolic (plasma level of lipids) and inflammatory markers (C-reactive protein) in obese young women. Further research is needed to explore the broader effects of whole-body electromyostimulation on physical and cardiometabolic health.

Abstract
Beach handball is a fully developed sporting discipline on all five continents which has attracted the attention of researchers in the last decade, resulting in a proliferation of different studies focusing on players but not on referees. The main objective of this cross-sectional research was to determine the physical demands on elite male beach handball referees in four different competitions: U18 male; U18 female; senior male; and senior female. Twelve elite federated male referees (age: 30.86 ± 8 years; body height: 175.72 ± 4.51 cm; body weight: 80.18 ± 17.99 kg; fat percentage: 20.1 ± 4.41%; national or international experience) belonging to the Technical Committee of the Royal Spanish Handball Federation were recruited for this the study. The physical demands required of referees in official matches were measured by installing a GPS device. The sampling frequency used to record their speed and distance was 15 Hz. A triaxial accelerometer (100 Hz) was used to determine their acceleration. An analysis of variance (ANOVA) between competitions with post hoc comparisons using the Bonferroni adjustment was used to compare among categories. A higher distance covered in zone 1 and speeds of 0 to 6 km-h-1 were recorded. Most accelerations and decelerations occurred in zones 0 and 1 (zone 0: 0 to 1 m·s-2; zone 1: 1 to 2 m·s-2). The lack of differences (p > 0.05) between most analysed variables suggest quite similar physical demands of the four analysed competitions. These results provide relevant information to design optimal training plans oriented to the real physical demands on referees in an official competition.

Abstract
CONTEXT The inclusion of transgender people in elite sport has been a topic of debate. This narrative review examines the impact of gender-affirming hormone therapy (GAHT) on physical performance, muscle strength, and markers of endurance. EVIDENCE ACQUISITION MEDLINE and Embase were searched using terms to define the population (transgender), intervention (GAHT), and physical performance outcomes. EVIDENCE SYNTHESIS Existing literature comprises cross-sectional or small uncontrolled longitudinal studies of short duration. In nonathletic trans men starting testosterone therapy, within 1 year, muscle mass and strength increased and, by 3 years, physical performance (push-ups, sit-ups, run time) improved to the level of cisgender men. In nonathletic trans women, feminizing hormone therapy increased fat mass by approximately 30% and decreased muscle mass by approximately 5% after 12 months, and steadily declined beyond 3 years. While absolute lean mass remains higher in trans women, relative percentage lean mass and fat mass (and muscle strength corrected for lean mass), hemoglobin, and VO2 peak corrected for weight was no different to cisgender women. After 2 years of GAHT, no advantage was observed for physical performance measured by running time or in trans women. By 4 years, there was no advantage in sit-ups. While push-up performance declined in trans women, a statistical advantage remained relative to cisgender women. CONCLUSION Limited evidence suggests that physical performance of nonathletic trans people who have undergone GAHT for at least 2 years approaches that of cisgender controls. Further controlled longitudinal research is needed in trans athletes and nonathletes.

Abstract
Investigating the relationship between alcohol consumption and physical performance, we used data from the 2015-2018 Know Your Heart study on 4215 adults aged 35-69 from Arkhangelsk and Novosibirsk, Russia. We classified participants' drinking status into non-drinking, non-problem drinking, hazardous drinking, and harmful drinking based on their self-reported drinking behaviors. To evaluate physical performance, we developed a Composite Physical Performance Scale (CPPS), which combined the results of three functional tests: grip strength (GS), closed-eyes balance, and chair rises (CR). We applied multivariable linear regression to assess the relationship between alcohol consumption and CPPS score, and ordinal logistic regression to explore the associations between alcohol consumption and the three functional tests separately. The results showed that harmful drinking was associated with lower CPPS scores compared to non-problem drinking. Among harmful drinking men, the decrease in CPPS scores was explained by all three tests equally and exceptionally by GS among women. Non-drinking was also associated with decreased CPPS, linked to lower GS and CR scores in men, and only lower GS scores in women. The study revealed a reduced physical performance in the non-drinking and harmful drinking groups compared to non-problem drinking.

Abstract
BACKGROUND Low bone mass is an independent risk factor for osteoporotic fractures. We examined the association between physical performance and bone mass using quantitative ultrasound in community-dwelling postmenopausal Japanese women. METHODS We conducted a cross-sectional study on 524 community-dwelling postmenopausal Japanese women who were not being administered osteoporosis medications. Physical performance was assessed on the basis of grip strength, chair stand time, and functional reach. The stiffness index was measured as a quantitative ultrasound parameter for heel bone mass. RESULTS Physical performance, assessed by grip strength, chair stand time, and functional reach, and the stiffness index significantly decreased with age (both p<0.001). The multiple linear regression analysis showed that grip strength (p = 0.001), chair stand time (p = 0.004), and functional reach (p = 0.048) were significantly associated with the stiffness index after adjusting for age, body mass index, smoking, drinking, and exercise. CONCLUSIONS Physical performance was significantly associated with heel bone mass in community-dwelling postmenopausal Japanese women.

Abstract
INTRODUCTION Older people often experience a decline in their physical performance. Tests have been approved to evaluate this performance in person. Yet, the constraints associated with in-person assessments (e.g. lack of medical facilities, pandemic lockdown, and contagion risk) are making us contemplate setting up assessments remotely. OBJECTIVES To determine whether remote physical performance measurements of older adults are reliable and valid compared to face-to-face measurements. METHODS Forty-five subjects aged 65 and over completed the normal/fast speed test (NWT/FWT), the unipodal balance test (UBT), the normal/fast timed up and go test (NTUG/FTUG), the 5 and 10 rep sit to stand test (5STS and 10STS), the 30 sec chair stand (30CS), the 2 minute step test (2MST) and the flexibility before standing (SAD) once face-to-face and twice remotely, by two different observers. The intraclass correlation coefficients (ICC), the standard errors of measurement (SEM%) and minimum detectable changes (MDC%) were calculated for both intra- and inter-observer conditions, to assess the relative and the absolute reliability. An ICC value exceeding 0.90 indicates a very high reliability, while an ICC between 0.70 and 0.89 signifies a high reliability. In clinical practice, a SEM % of less than 10% is considered acceptable. A smaller MDC % indicates a measurement that is more sensitive to detecting changes. RESULTS Intra-observer relative reliability was very high (ICC>0.9) for the UBT, NWT, NTUG, FTUG, 5STS, 10STS, 30CS and the SAD; and high (ICC>0.7) for the 2MST and FWS. SEM% values ranged from 0% to 24.03% and MDC from 0% to 9.93%. Inter-observer relative reliability was considered very high (ICC>0.9) for all tests. SEM% values ranged from 0% to 17.68% and MDC from 0% to 7.32%. CONCLUSION Our findings demonstrate that remote assessments exhibited consistently high to very high levels of intra- and inter-observer relative reliability when compared to face-to-face assessments. Additionally, certain remote evaluations showed acceptable absolute reliability, making them viable alternatives for healthcare professionals when in-person assessments are not feasible in clinical practice.
