Abstract
Research into the molecular basis of disease trajectory and Long-COVID is important to get insights toward underlying pathophysiological processes. The objective of this study was to investigate inflammation-mediated changes of metabolism in patients with acute COVID-19 infection and throughout a one-year follow up period. The study enrolled 34 patients with moderate to severe COVID-19 infection admitted to the University Clinic of Innsbruck in early 2020. The dynamics of multiple laboratory parameters (including inflammatory markers [C-reactive protein (CRP), interleukin-6 (IL-6), neopterin] as well as amino acids [tryptophan (Trp), phenylalanine (Phe) and tyrosine (Tyr)], and parameters of iron and vitamin B metabolism) was related to disease severity and patients' physical performance. Also, symptom load during acute illness and at approximately 60 days (FU1), and one year after symptom onset (FU2) were monitored and related with changes of the investigated laboratory parameters: During acute infection many investigated laboratory parameters were elevated (e.g., inflammatory markers, ferritin, kynurenine, phenylalanine) and enhanced tryptophan catabolism and phenylalanine accumulation were found. At FU2 nearly all laboratory markers had declined back to reference ranges. However, kynurenine/tryptophan ratio (Kyn/Trp) and the phenylalanine/tyrosine ratio (Phe/Tyr) were still exceeding the 95th percentile of healthy controls in about two thirds of our cohort at FU2. Lower tryptophan concentrations were associated with B vitamin availability (during acute infection and at FU1), patients with lower vitamin B12 levels at FU1 had a prolonged and more severe impairment of their physical functioning ability. Patients who had fully recovered (ECOG 0) presented with higher concentrations of iron parameters (ferritin, hepcidin, transferrin) and amino acids (phenylalanine, tyrosine) at FU2 compared to patients with restricted ability to work. Persistent symptoms at FU2 were tendentially associated with IFN-γ related parameters. Women were affected by long-term symptoms more frequently. Conclusively, inflammation-mediated biochemical changes appear to be related to symptoms of patients with acute and Long Covid.

Abstract
OBJECTIVE To examine the physical function and respiratory muscle strength of patients - who recovered from critical COVID-19 - after intensive care unit discharge to the ward on Days one (D1) and seven (D7), and to investigate variables associated with functional impairment. METHODS This was a prospective cohort study of adult patients with COVID-19 who needed invasive mechanical ventilation, non-invasive ventilation or high-flow nasal cannula and were discharged from the intensive care unit to the ward. Participants were submitted to Medical Research Council sum-score, handgrip strength, maximal inspiratory pressure, maximal expiratory pressure, and short physical performance battery tests. Participants were grouped into two groups according to their need for invasive ventilation: the Invasive Mechanical Ventilation Group (IMV Group) and the Non-Invasive Mechanical Ventilation Group (Non-IMV Group). RESULTS Patients in the IMV Group (n = 31) were younger and had higher Sequential Organ Failure Assessment scores than those in the Non-IMV Group (n = 33). The short physical performance battery scores (range 0 - 12) on D1 and D7 were 6.1 ± 4.3 and 7.3 ± 3.8, respectively for the Non-Invasive Mechanical Ventilation Group, and 1.3 ± 2.5 and 2.6 ± 3.7, respectively for the IMV Group. The prevalence of intensive care unit-acquired weakness on D7 was 13% for the Non-IMV Group and 72% for the IMV Group. The maximal inspiratory pressure, maximal expiratory pressure, and handgrip strength increased on D7 in both groups, but the maximal expiratory pressure and handgrip strength were still weak. Only maximal inspiratory pressure was recovered (i.e., > 80% of the predicted value) in the Non-IMV Group. Female sex, and the need and duration of invasive mechanical were independently and negatively associated with the short physical performance battery score and handgrip strength. CONCLUSION Patients who recovered from critical COVID-19 and who received invasive mechanical ventilation presented greater disability than those who were not invasively ventilated. However, they both showed marginal functional improvement during early recovery, regardless of the need for invasive mechanical ventilation. This might highlight the severity of disability caused by SARS-CoV-2.

Abstract
Introduction Frailty and low physical performance are modifiable factors and, therefore, targets for interventions aimed at delaying driving cessation (DC). The objective was to determine the impact of frailty and physical performance on DC. Methods Multisite prospective cohort of older drivers. The key inclusion criteria are as follows: active driver age 65-79 years, possessing a valid driver's license, without significant cognitive impairment, and driving a 1996 car or a newer model car. Of the 2,990 enrolled participants, 2,986 (99.9%) had at least one frailty or Short Physical Performance Battery (SPPB) measure and were included in this study. In total, 42% of participants were aged 65-69 years, 86% were non-Hispanic white, 53% were female, 63% were married, and 41% had a high degree of education. The Fried Frailty Phenotype and the Expanded Short Physical Performance Battery (SPPB) from the National Health and Aging Trends Study were utilized. At each annual visit, DC was assessed by the participant notifying the study team or self-reporting after no driving activity for at least 30 days, verified via GPS. Cox proportional hazard models, including time-varying covariates, were used to examine the impact of the SPPB and frailty scores on time to DC. This assessment included examining interactions by sex. Results Seventy-three participants (2.4%) stopped driving by the end of year 5. Among women with a fair SPPB score, the adjusted hazard ratio (HR) of DC was 0.26 (95% confidence interval (CI) 0.10-0.65) compared to those with a poor SPPB score. For those with a good SPPB score, the adjusted HR of DC had a p-value of <0.001. Among men with a fair SPPB score, the adjusted hazard ratio (HR) of DC was 0.45 (95% CI 0.25-0.81) compared to those with a poor SPPB score. For men with a good SPPB score, the adjusted HR of DC was 0.19 (95% CI 0.10-0.36). Sex was not an effect modifier between frailty and DC. For those who were categorized into pre-frail or frail, the adjusted ratio of HR to DC was 6.1 (95% CI 2.7-13.8) compared to those who were not frail. Conclusion and relevance Frailty and poor physical functioning are major risk factors for driving cessation. Staying physically active may help older adults to extend their driving life expectancy and mobility.

Physical performance and sarcopenia assessment in patients with a recent fracture visiting the Fracture Liaison Service. Osteoporos Int 2024; 35:851-862. [PMID: 38349472 PMCID: PMC11031480 DOI: 10.1007/s00198-023-07009-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 12/20/2023] [Indexed: 04/20/2024]
Abstract
Impaired physical performance is associated with increased fracture risk. Performance on four physical functioning tests and prevalence of sarcopenia were assessed for 1789 fracture patients and compared to reference data. Performance was low on all tests, especially for patients with a hip, major or ≥ 1 prevalent vertebral fracture. PURPOSE INTRODUCTION Impaired physical performance and sarcopenia are associated with increased fracture risk. This study aims to assess physical performance and the prevalence of sarcopenia in patients with a recent clinical fracture attending the Fracture Liaison Service (FLS) compared to population means. METHODS In this cross-sectional study, chair stand test (CST), handgrip strength (HGS), timed-up-and-go (TUG), 6-min walking-test (6MWT), and sarcopenia (following EWGSOP2) were assessed. The proportion of patients with impaired/poor performance compared to reference data was calculated (Z-score: ≥ - 2SD to < - 1 (impaired) and < - 2 SD (poor)). Associations of fracture type, sex, age, and time since fracture with Z-scores were assessed using linear regression analyses. RESULTS A total of 1789 consecutive FLS patients were included (median age (IQR): 66 (59-74), 70.7% females, 3.9 (± 1.6) months after fracture). The prevalence of impaired/poor performance for CST, HGS, TUG, and 6MWT was 39.2%, 30.4%, 21.9%, and 71.5%, respectively (expected proportion of 16%) and 2.8% had sarcopenia. Lower Z-scores (P < 0.001) were found for hip, major, and ≥ 1 prevalent vertebral fracture (VF) in CST (major: regression coefficient (B) (95%CI) = - 0.25 [- 0.34, - 0.16]; hip: B = - 0.32 [- 0.47, - 0.17], VF: B = - 0.22 [- 0.34, - 0.11]), TUG; (major: B = - 0.54 [- 0.75, - 0.33]; hip: B = - 1.72 [- 2.08, -1.35], VF: B = - 0.61 [- 0.88, - 0.57]), 6MWT (major: B = - 0.34 [- 0.47, - 0.21]; hip: B = - 0.99 [- 1,22, - 0.77], VF: B = - 0.36 [- 0.53, - 0.19]). CONCLUSIONS Physical performance is significantly lower in FLS patients compared to healthy peers, especially in patients with hip, major or prevalent VF. These findings underline the need to assess and improve the physical performance of FLS patients, despite a low prevalence of sarcopenia.

Abstract
PURPOSE It is known that clinical Pilates improves strength, core stability, balance, gait, fatigue, and quality of life (QOL) in patients with multiple sclerosis (PwMS). On the other hand, there is insufficient information about whether similar benefits can be achieved with Pilates-based telerehabilitation (Pilates-TR). We aimed to investigate the effects of Pilates-TR on physical performance and QOL in PwMS. METHODS Thirty PwMS were recruited and randomly allocated into two groups. The Pilates-TR group received Pilates-TR via videoconferences three days per week during six weeks at home. The control group (CG) was a waitlist with no Pilates-TR treatment. Physical performance measures included extremity muscle strength, core endurance and power, balance, gait analysis, and functional exercise capacity. In addition, fatigue and QOL were evaluated. RESULTS Extremity muscle strength, core endurance and power, balance, walking speed, cadence, distance, functional exercise capacity, and QOL were improved after Pilates-TR (p < 0.05). Fatigue level and the effects of fatigue on functions decreased in Pilates-TR, while fatigue level increased in CG (p < .05). The CG showed no changes in any other measurements (p > .05). CONCLUSION Pilates-TR was effective in improving physical performance and QOL in PwMS. Pilates-TR can be recommended as an effective option, especially for patients with barriers to reaching the clinic. Trial registration: ClinicalTrials.gov (NCT04838886).

Abstract
OBJECTIVE Loss of functional independence is more likely in older adults who reside in an institution as a consequence of a decline in muscle mass and a loss of force production capacity. The aim of this review was to assess the effect of whole-body vibration (WBV) interventions on the strength, balance, and mobility of nursing home residents older than 80 years. METHODS An electronic search in MEDLINE, Scopus, and CINAHL databases was conducted. Randomized controlled trials that involved nursing home residents older than 80 years, that investigated WBV interventions compared with nonintervention, usual care, or placebo, and that measured physical function outcomes including strength, balance, gait, and mobility were included. Risk of bias was assessed by 2 reviewers using the Physiotherapy Evidence Database scale. The standardized mean differences (SMD) between the experimental and control groups were calculated with a random-effects model for each outcome, and subgroup analysis was conducted for different outcomes. RESULTS In total, 2864 articles were identified; of these, 14 randomized controlled trials met the inclusion criteria. The meta-analysis revealed that WBV significantly increased the lower limb muscle strength (SMD = 0.59; 95% CI = 0.16 to 1.03), mobility (SMD = 0.45; 95% CI = 0.10 to 0.81), gait score (SMD = 0.26; 95% CI = 0.01 to 0.51), balance (SMD = 0.41; 95% CI = 0.01 to 0.81), and physical performance (SMD = 1.33; 95% CI = 0.33 to 2.33). CONCLUSION WBV may be an effective intervention to improve the strength, balance, mobility, walking ability, and physical performance of older nursing home residents. IMPACT WBV presents a safe, accessible alternative for improving health in this vulnerable population, warranting further research and integration into health care practices.

Virtual reality exergames for improving physical function, cognition and depression among older nursing home residents: A systematic review and meta-analysis. Geriatr Nurs 2024; 57:31-44. [PMID: 38503146 DOI: 10.1016/j.gerinurse.2024.02.032] [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: 12/18/2023] [Revised: 02/16/2024] [Accepted: 02/21/2024] [Indexed: 03/21/2024]
Abstract
OBJECTIVE To explore the effectiveness of virtual reality (VR) exergames on physical function, cognition and depression among older nursing home residents. METHODS A systematic review and meta-analysis were conducted. The PubMed, Ovid, Embase, Cochrane, CINAHL, and Web of Science databases were searched for relevant studies from inception until June 1, 2023. The reviewers independently completed the study selection, data extraction and quality assessment. Subgroup analyses were conducted to explore the sources of between-study heterogeneity and to determine whether participant or intervention characteristics influenced effect sizes. RESULTS Eighteen studies met the inclusion criteria and were selected for qualitative and quantitative synthesis. The overall methodological quality was relatively high, and the overall evidence grade was moderate. VR exergames had a large effect on physical function, including mobility [SMD=-0.66, P < 0.001], balance [SMD=0.95, P < 0.001], and lower limb strength [SMD=0.53, P = 0.0009]; and a moderate effect on cognition [SMD=0.48, P = 0.02] and depression [SMD=-0.72, P = 0.03]. Subgroup analyses revealed that a training frequency of 2 sessions per week and coordinating with physiotherapists yielded greater improvements in mobility (P = 0.009; P = 0.0001). VR exergames had especially beneficial effects on balance for physically fit participants (P = 0.03) and on cognition for participants with cognitive impairment (P = 0.01). Additionally, regarding the improvement of depression, commercial VR exergames were superior to self-made systems (P = 0.03). CONCLUSION VR exergames can provide a positive impact on physical function, cognition and depression among older nursing home residents. The study also demonstrated the different benefits of exergames between participants who were physically fit and those with cognitive impairment, which is considered as an innovative, cost-efficient and sustainable approach. Specifically, commercial VR exergame programs with a frequency of 2 sessions per week and coordinating with physiotherapists may be the most appropriate and effective option.

Abstract
OBJECTIVES Reliability of the Short Physical Performance Battery (SPPB) are rarely examined among older adults with mild cognitive impairment (MCI). This study aimed to investigate the test-retest reliability and minimal detectable change (MDC) of the SPPB in older adults with MCI. METHODS Participants included 100 older adults with MCI. The SPPB was assessed with the first 2 assessments separated by a 20-min interval and the third separated by a 1-week interval. The intraclass correlation coefficient (ICC) and MDC values were estimated. RESULTS The intraday ICC was 0.73 for the SPPB score, 0.90 for the 4-m walk time (4mwt), and 0.95 for the 5-times chair stand time (5cst); the corresponding interday ICC values were 0.76, 0.89, and 0.91, respectively. The MDC values ranged from 1.1 to 1.2 for the SPPB score, from 0.77 to 0.80 s for the 4mwt, and from 1.32 to 1.77 for the 5cst. CONCLUSIONS The SPPB had satisfactory reliability among older adults with MCI. The test-retest reliability of the SPPB is sufficient (>0.7) for group comparisons. Moreover, the test-retest reliability for the 4mwt and 5cst subscale performances is acceptable (> 0.9) for individual-level measurements over time.

Abstract
OBJECTIVES To investigate the relation between cognitive and motor performance in individuals with mild traumatic brain injury (mTBI) and examine differences in both cognitive and motor performance between adults after mTBI and healthy controls. DESIGN Multi-center, cross-sectional study. SETTING Three institutional sites (Courage Kenny Research Center, Minneapolis, MN, Oregon Health & Science University, Portland, OR, and University of Utah, Salt Lake City, UT). PARTICIPANTS Data were collected from 110 participants (N=110), including those with mTBI and healthy controls, who completed cognitive and physical performance assessments. INTERVENTIONS Not applicable. OUTCOME MEASURES Cognitive assessments involved the Automated Neuropsychological Assessment Metrics to evaluate domains of attention, memory, reaction time, processing speed, and executive function. Physical performance was evaluated through clinical performance assessments, such as the 1-min walk test, the modified Illinois Agility Test, the Functional Gait Assessment Tool, the High-Level Mobility Assessment Tool, a complex turning course, and a 4-Item Hybrid Assessment of Mobility for mTBI. Participants also completed additional trials of the 1-min walk test, modified Illinois Agility Test, and complex turning course with a simultaneous cognitive task. RESULTS Individuals with mTBI performed worse on cognitive assessments, as well as several of the physical performance assessments compared with healthy controls. Complex tasks were more strongly related to cognitive assessments compared with simple walking tasks. CONCLUSIONS Combining complex motor tasks with cognitive demands may better demonstrate functional performance in individuals recovering from mTBI. By understanding the relation between cognitive and physical performance in individuals recovering from mTBI, clinicians may be able to improve clinical care and assist in return to activity decision-making.

Abstract
BACKGROUND The efficacy of creatine replacement through supplementation for the optimization of physical function in the population at risk of functional disability is unclear. METHODS We conducted a systematic literature search of MEDLINE, EMBASE, the Cochrane Library, and CINAHL from inception to November 2022. Studies included were randomized controlled trials (RCTs) comparing creatine supplementation with placebos in older adults and adults with chronic disease. The primary outcome was physical function measured by the sit-to-stand test after pooling data using random-effects modeling. We also performed a Bayesian meta-analysis to describe the treatment effect in probability terms. Secondary outcomes included other measures of physical function, muscle function, and body composition. The risk of bias was assessed using the Cochrane risk-of-bias tool. RESULTS We identified 33 RCTs, comprising 1076 participants. From six trials reporting the primary outcome, the pooled standardized mean difference (SMD) was 0.51 (95% confidence interval [CI]: 0.01-1.00; I2 = 62%; P = 0.04); using weakly informative priors, the posterior probability that creatine supplementation improves physical function was 66.7%. Upper-body muscle strength (SMD: 0.25; 95% CI: 0.06-0.44; I2 = 0%; P = 0.01), handgrip strength (SMD 0.23; 95% CI: 0.01-0.45; I2 = 0%; P = 0.04), and lean tissue mass (MD 1.08 kg; 95% CI: 0.77-1.38; I2 = 26%; P < 0.01) improved with creatine supplementation. The quality of evidence for all outcomes was low or very low because of a high risk of bias. CONCLUSION Creatine supplementation improves sit-to-stand performance, muscle function, and lean tissue mass. It is crucial to conduct high-quality prospective RCTs to confirm these hypotheses (PROSPERO number, CRD42023354929).

Abstract
Importance Identifying factors contributing to sustained physical functioning is critical for the health and well-being of the aging population, especially as physical functioning may precede and predict subsequent health outcomes. Prior work suggests optimism may protect health, but less is known about the association between optimism and objective physical functioning measures as individuals age. Objective To evaluate the longitudinal association between optimism and 3 physical functioning measures. Design, Setting, and Participants This was a prospective cohort study using data from the Women's Health Initiative (WHI) with participants recruited from 1993 to 1998 and followed up over 6 years. Data analysis was conducted from January 2022 to July 2022. Participants included postmenopausal women older than 65 years recruited from 40 clinical centers in the US. Exposure Optimism was assessed at baseline using the Life Orientation Test-Revised. Main Outcomes and Measures Physical functioning was measured at 4 time points across 6 years by study staff evaluating performance in grip strength, timed walk, and chair stands. Results The final analytic sample included 5930 women (mean [SD] age, 70 [4] years). Linear mixed-effects models controlling for demographics, depression, health status, and health behaviors showed that higher optimism was associated with higher grip strength (β = 0.36; 95% CI, 0.21-0.50) and number of chair stands (β = 0.05; 95% CI, 0.01-0.10) but not timed walk at baseline. Higher optimism was also associated with slower rates of decline in timed walk (β = -0.09; 95% CI, -0.13 to -0.04) and number of chair stands (β = 0.01; 95% CI, 0-0.03) but not grip strength over time. Cox proportional hazards models showed that higher optimism was associated with lower hazards of reaching clinically defined thresholds of impairment for all 3 outcomes over 6 years of follow-up. For example, in fully adjusted models, for a 1-SD increase in optimism, hazard ratios for reaching impairment thresholds were 0.86 (95% CI, 0.80-0.92) for grip strength, 0.94 (95% CI, 0.88-1.01) for timed walk, and 0.91 (95% CI, 0.85-0.98) for chair stands. Conclusion and Relevance In this cohort study of postmenopausal women, at baseline, higher optimism was associated with higher grip strength and number of chair stands but not with the time it took to walk 6 m. Higher optimism at baseline was also associated with maintaining healthier functioning on 2 of the 3 performance measures over time, including less decline in walking speed and in number of chair stands women could perform over 6 years of follow-up. Given experimental studies suggesting that optimism is modifiable, it may be a promising target for interventions to slow age-related declines in physical functioning. Future work should explore associations of optimism with maintenance of physical functioning in diverse populations.

Physical performance strongly predicts all-cause mortality risk in a real-world population of older diabetic patients: machine learning approach for mortality risk stratification. Front Endocrinol (Lausanne) 2024; 15:1359482. [PMID: 38745954 PMCID: PMC11091327 DOI: 10.3389/fendo.2024.1359482] [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: 12/21/2023] [Accepted: 04/12/2024] [Indexed: 05/16/2024] Open
Abstract
Background Prognostic risk stratification in older adults with type 2 diabetes (T2D) is important for guiding decisions concerning advance care planning. Materials and methods A retrospective longitudinal study was conducted in a real-world sample of older diabetic patients afferent to the outpatient facilities of the Diabetology Unit of the IRCCS INRCA Hospital of Ancona (Italy). A total of 1,001 T2D patients aged more than 70 years were consecutively evaluated by a multidimensional geriatric assessment, including physical performance evaluated using the Short Physical Performance Battery (SPPB). The mortality was assessed during a 5-year follow-up. We used the automatic machine-learning (AutoML) JADBio platform to identify parsimonious mathematical models for risk stratification. Results Of 977 subjects included in the T2D cohort, the mean age was 76.5 (SD: 4.5) years and 454 (46.5%) were men. The mean follow-up time was 53.3 (SD:15.8) months, and 209 (21.4%) patients died by the end of the follow-up. The JADBio AutoML final model included age, sex, SPPB, chronic kidney disease, myocardial ischemia, peripheral artery disease, neuropathy, and myocardial infarction. The bootstrap-corrected concordance index (c-index) for the final model was 0.726 (95% CI: 0.687-0.763) with SPPB ranked as the most important predictor. Based on the penalized Cox regression model, the risk of death per unit of time for a subject with an SPPB score lower than five points was 3.35 times that for a subject with a score higher than eight points (P-value <0.001). Conclusion Assessment of physical performance needs to be implemented in clinical practice for risk stratification of T2D older patients.

Silva T, Oliveira M, Oliveira E, Macena R, de Oliveira Silva GT, Câmara SMA, Micussi M. Are women with endometriosis more likely to experience reduced physical performance compared to women without the condition? PeerJ 2024; 12:e16835. [PMID: 38666082 PMCID: PMC11044877 DOI: 10.7717/peerj.16835] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 01/04/2024] [Indexed: 04/28/2024] Open
Abstract
Background Endometriosis is a condition of the female reproductive system associated with pelvic pain. Chronic pain can affect physical performance by limiting the functional activities, thus, it is hypothesized that women with endometriosis may also present decreased functional capacity, decreased strength, and mobility. The objective of this study is to compare physical performance in women with and without endometriosis. Methods This is a cross-sectional study composed of 115 women equally divided into two groups: the endometriosis group (EG), composed of women with a confirmed diagnosis of the disease by magnetic resonance imaging, and the comparator group (CG), consisting of women without suspicion of the disease. Physical performance (dependent variable) was assessed using hand dynamometry, the 6-min walk test (6MWT), gait speed, and the chair stands test. CG participants performed the tests during the luteal phase of the menstrual cycle. Descriptive statistics, unpaired t-tests, and chi-square tests were used to describe and compare the groups. Multiple linear regression tested the associations adjusted for covariates (age, income, education, age at menarche, and body mass index). Results The EG had worse gait speed (mean difference: -0.11; 95% CI: [-0.18 to -0.04]), weaker grip strength (mean difference: -3.32; 95% CI: [-5.30 to -1.33]), shorter distance covered in the 6MWT (mean difference: -83.46; 95% CI: [-121.38 to -45.53]), and a lower number of repetitions in the chair stands test (mean difference: -8.44; 95% CI: [-10.64 to -6.25]) than the CG, even after adjusting for covariates. Conclusion Grip strength, lower limb strength, mobility, and functional capacity were worse in women diagnosed with endometriosis. Women with endometriosis should be encouraged to engage in physical exercise, adopt healthy lifestyle habits, and participate in rehabilitation activities to control pain, with the aim of reducing functional impairments.

A 12-week multicomponent exercise program enhances frailty by increasing robustness, improves physical performance, and preserves muscle mass in older adults with HIV: MOVIhNG study. Front Public Health 2024; 12:1373910. [PMID: 38694984 PMCID: PMC11062244 DOI: 10.3389/fpubh.2024.1373910] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 03/06/2024] [Indexed: 05/04/2024] Open
Abstract
Background Our aim was to analyze the effects of a multicomponent exercise program (MEP) on frailty and physical performance in older adults with HIV (OAWH) since exercise can reverse frailty in the older population overall, but there is no data for OAWH. Methods A prospective longitudinal study with intervention and control group was designed. Sedentary adults 50 or over with and without HIV were included. The intervention was a 12-week home-based MEP. Dependent variables were frailty (frailty phenotype), physical performance (Senior Fitness Test), muscle mass (ASMI) by bioimpedance. Pre- and postintervention measurements were analyzed using McNemar's test for categorical variables and the Wilcoxon signed-rank test for quantitative variables. Results 40 OAWH and 20 OA without HIV. The median age was 56.5 years. 23.3% were women. The prevalence of frailty was 6.6% with no frail HIV-negative participants. Three of the four frail HIV-participants transitioned two (50%) from frail to prefrail and one (25%) to robust after the MEP. In participants with an adherence ≥50%, physical performance was significantly improved [basal vs. 12 week]: upper extremity strength [13 (13-15) vs. 16 (15-19), p = 0.0001], lower extremity strength [13 (11-16) vs. 15 (13-16), p = 0.004], aerobic endurance [62 (55-71) vs. 66 (58-80), p = 0.005]. Participants with low adherence experienced a significant worsening in ASMI [8.35 (7.44-9.26) vs. 7.09 (6.08-8.62), p = 0.03]. Conclusion A 12-week MEP enhances frailty by increasing robustness in OAWH, and improves physical performance, and preserves muscle mass in older adults with good adherence to the MEP independently of HIV status.

Effects of active exergames on physical performance in older people: an overview of systematic reviews and meta-analysis. Front Public Health 2024; 12:1250299. [PMID: 38655514 PMCID: PMC11037520 DOI: 10.3389/fpubh.2024.1250299] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2023] [Accepted: 02/29/2024] [Indexed: 04/26/2024] Open
Abstract
This overview assessed the available body of published peer-reviewed systematic reviews and meta-analyses related to the effects of active exergames compared with active/passive control on physical performance outcomes in older people. The methodological quality and certainty of evidence were assessed using PRISMA, AMSTAR 2, and GRADE. The protocol was registered in PROSPERO (code: CRD42023391694). The main outcomes indicate that 4,477 records, five systematic reviews, and 10 meta-analyses were included. The AMSTAR-2 reported six meta-analyses with high methodological quality, four moderate quality, two systematic reviews with low quality, and three very-low quality. Meta-analysis was performed on balance using the Berg Balance Scale (BBS) and Timed Up-and-Go (TUG) tests, on cardiorespiratory fitness using the 6-min walk test, and on upper and lower limbs muscle strength using the handgrip strength, knee extension, and 30-s chair stand tests. Significant differences in favor of the active exergames groups concerning active/passive groups were reported in BBS (SMD = 0.85; 95% CI = 0.12-1.58; I2 = 96%; p = 0.02), TUG (SMD = 1.44; 95% CI = 0.71-2.16; I2 = 97%; p < 0.0001), and 30-s chair stand test (SMD = 0.79; 95% CI = 0.33-1.25; I2 = 88%; p = 0.0008). However, no significant differences were reported in favor of the active exergames groups in 6-min walk (SMD = 0.93; 95% CI = -0.64 to 2.50; I2 = 95%; p = 0.24), handgrip strength (SMD = 0.67; 95% CI = -0.04 to 1.38; I2 = 84%; p = 0.06), and knee extension tests (SMD = 0.20; 95% CI = -0.05 to 0.44; I2 = 95%; p = 0.12) compared to active/passive control. However, it was impossible to perform a meta-analysis for the variables of walking speed as a fall risk due to the diversity of instruments and the small number of systematic reviews with meta-analysis. In conclusion, interventions utilizing active exergames have shown significant improvements in the static and dynamic balance and lower limb muscle strength of apparently healthy older people, compared to control groups of active/inactive participants, as measured by BBS, TUG, and 30-s chair stand tests. However, no significant differences were found in the 6-min walk, HGS, and knee extension tests. Systematic review registration PROSPERO, CRD42023391694.

Abstract
BACKGROUND Falls have a major impact on individual patients, their relatives, the healthcare system and related costs. Physical exercise programmes that include multiple categories of exercise effectively reduce the rate of falls and risk of falling among older adults. METHODS This 12-month, assessor-blinded, three-armed multicentre randomised clinical trial was conducted in adults aged ≥ 65 years identified as at risk of falling. Four hundred and five participants were randomly allocated into 3 groups: experimental group (n = 166) with the Test&Exercise partially supervised programme based on empowerment delivered with a tablet, illustrated manual and cards, reference group (n = 158) with the Otago partially supervised programme prescribed by a physiotherapist delivered with an illustrated manual and control group (n = 81) with the Helsana self-administrated programme delivered with cards. Experimental and reference groups received partially supervised programmes with 8 home sessions over 6 months. Control group received a self-administered program with a unique home session. The 3 groups were requested to train independently 3 times a week for 12 months. Primary outcome was the incidence rate ratio of self-reported falls over 12 months. Secondary outcomes were fear of falling, basic functional mobility and balance, quality of life, and exercise adherence. RESULTS A total of 141 falls occurred in the experimental group, 199 in the reference group, and 42 in the control group. Incidence rate ratios were 0.74 (95% CI 0.49 to 1.12) for the experimental group and 0.43 (95% CI 0.25 to 0.75) for the control group compared with the reference group. The Short Physical Performance Battery scores improved significantly in the experimental group (95% CI 0.05 to 0.86; P = 0.027) and in the reference group (95% CI 0.06 to 0.86; P = 0.024) compared with the control group. CONCLUSION The self-administered home-based exercise programme showed the lowest fall incidence rate, but also the highest dropout rate of participants at high risk of falling. Both partially supervised programmes resulted in statistically significant improvements in physical performance compared with the self-administered programme. TRIAL REGISTRATION NCT02926105.

Abstract
PURPOSE This study aimed to investigate the effects of a demanding military field exercise on physical performance, body composition, and muscle cellular outcomes in men and women. METHODS Ten men (20.5 ± 0.5 yr) and 8 women (21.4 ± 1.4 yr) completed a 10-d field exercise consisting of extensive physical activity with food and sleep restriction. Acquisition of body composition, physical performance, blood, and muscle biopsies samples were done before and 1, 7, and 14 d after the exercise. RESULTS There were no sex differences in the response to the exercise. Body mass was decreased with 5.6% ± 1.8% and fat mass with 31% ± 11% during the exercise. Both were still reduced after 14 d (2.5% ± 2.3%, P < 0.001, and 12.5% ± 7.7%, P < 0.001, respectively). Isometric leg strength did not change. Peak leg extension torque at 240°·s -1 and counter movement jump height were reduced with 4.6% ± 4.8% ( P = 0.012) and 6.7% ± 6.2% ( P < 0.001), respectively, and was still reduced after 14 d (4.3% ± 4.2%, P = 0.002, and 4.1% ± 4.7%, P = 0.030). No changes occurred in fiber CSA, fiber types, proteins involved in calcium handling, or HSP70. During the exercise, αB-crystallin levels decreased by 14% ± 19% ( P = 0.024) in the cytosolic fraction and staining intensity on muscle sections tended to increase (17% ± 25%, P = 0.076). MuRF1 levels in the cytosolic fraction tended to decrease (19% ± 35%) and increased with 85% ± 105% ( P = 0.003) in the cytoskeletal fraction 1 wk after the exercise. CONCLUSIONS The field exercise resulted in reduced body mass and physical performance in both sexes. The ability to produce force at high contraction velocities and explosive strength was more affected than isometric strength, but this was not related to any changes in fiber type composition, fiber area, Ca 2+ handling, or fiber type-specific muscle damage.

Abstract
BACKGROUND Chronic joint hypermobility has been attributed to repetitive ligamentous microtrauma, benign joint hypermobility syndrome (BJHS), or genetic connective tissue disorders that lead to pain and functional impairment, especially among females. Chronic wrist hypermobility (CWH) prevalence, etiology, and effects on proprioception, strength, and function have yet to be established. PURPOSE This pilot study aimed to determine the CWH prevalence among adults; its effects on proprioception, strength, and function; and whether these effects are gender based. STUDY DESIGN This was a quasi-experimental cross-sectional study. METHODS Ninety wrists (55 participants, mean age 27.46 years) with no wrist range of motion (ROM) restrictions or previous trauma for ≥6 months were screened for CWH based on an exploratory set of diagnostic criteria. Fifty-eight wrists (34 adults) were allocated to a CWH group, and 32 wrists (21 adults) were allocated to a healthy control group. Twenty-five CWH and 25 healthy control matched (gender, age, and handedness) participants were compared. Assessment included the active wrist joint position sense test, hand-held dynamometry for wrist extension and grip strength, and the patient-rated wrist evaluation for function. Testers were blinded to group allocation. RESULTS A 64.4% CWH prevalence existed among CWH participants, who were mostly asymptomatic females (74%). Frequent etiologic factors were midcarpal (96.5%) and scapholunate (39%) instabilities and BJHS (37%), which was higher among females (30%) than males (8%). Independent t-tests showed statistically significant (p < 0.05) group differences in wrist proprioception, wrist isometric extension, grip strength, and function with moderate-high (0.41-0.75) effect size. No significant gender differences existed in proprioception and function. CONCLUSIONS CWH is very prevalent among functional independent young adults with atraumatic midcarpal and intercarpal ligamentous laxities and BJHS. CWH prevails among women and adversely affects wrist proprioception, strength, and function. The study's specific CWH diagnostic criteria may be useful for clinicians to identify and timely manage impacted individuals by CWH.

Abstract
Changes in physiological markers and physical performance in relation to paratroopers' initial body composition were investigated during a 20-day winter military field training (MFT) and the subsequent 10-day recovery period. Body composition, serum hormone concentrations and enzymatic biomarkers, and physical performance of 58 soldiers were measured before, during, and after MFT. Comparisons were done according to soldiers' body fat percentage before MFT between low-fat (<12% body fat) and high-fat (>12% body fat) groups. Correlations between body fat percentage preceding MFT and changes in muscle mass, physical performance, and serum hormone concentrations and enzymatic biomarkers were investigated. It was hypothesized that soldiers with a higher fat percentage would have smaller decrements in muscle mass, physical performance, and serum testosterone concentration. The change in muscle and fat mass was different between groups (p < 0.001) as the low-fat group lost 0.8 kg of muscle mass and 2.0 kg of fat mass, while there was no change in muscle mass and a loss of 3.7 kg of fat mass in the high-fat group during MFT. Fat percentage before MFT correlated with the changes in muscle mass (R2 = 0.26, p < 0.001), serum testosterone concentration (R2 = 0.22, p < 0.001), and evacuation test time (R2 = 0.10, p < 0.05) during MFT. The change in muscle mass was correlated with the changes in evacuation test time (R2 = 0.11, p < 0.05) and countermovement jump test results (R2 = 0.13, p < 0.01) during MFT. Soldiers with a higher initial fat percentage lost less muscle mass, and had smaller decrements in some aspects of physical performance, as well as in serum testosterone concentration during MFT.

Abstract
OBJECTIVES Inflammation and impaired muscle synthesis are important factors of sarcopenia. Plant protein may reduce inflammation but may not be as efficient as animal protein in providing essential amino acids. We therefore examined the associations between dietary protein intake and changes in muscle mass and physical performance, incident sarcopenia, and the interaction effect of inflammation. DESIGN Prospective cohort study. SETTING The Mr. OS and Ms. OS (Hong Kong) cohort. PARTICIPANTS A total of 2,811 sarcopenia-free participants and 569 sarcopenia participants aged ≥65 years were recruited from communities. MEASUREMENTS Dietary protein intake was assessed using a validated food frequency questionnaire. Serum high-sensitivity C-reactive protein (hs-CRP) was measured. Linear regression examined the associations between dietary protein intake and 4-year changes in muscle mass and physical performance. Cox regression examined the association between dietary protein intake and incident sarcopenia. RESULTS Higher plant protein intake, but not total and animal protein, was associated with less decline in muscle mass and gait speed among sarcopenia-free participants. Conversely, higher ratio of animal-to-plant protein was associated with reduced muscle mass loss among participants with sarcopenia. The highest tertile of plant protein intake was associated with lower incident sarcopenia risk (HR: 0.75, 95% CI: 0.57-0.98; P-trend = 0.034) compared to the lowest tertile. Notably, this association was observed among participants with higher serum hs-CRP levels (HR: 0.57, 95% CI: 0.34-0.95), but not in those with lower hs-CRP levels. CONCLUSION Dietary animal and plant protein intake have differential associations with muscle mass and physical performance in older adults with and without sarcopenia. The role of plant protein in preventing sarcopenia involves modulation of inflammation.

[PMID: 38350303 DOI: 10.1016/j.jnha.2024.100184] [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: 11/09/2023] [Revised: 01/28/2024] [Accepted: 01/29/2024] [Indexed: 02/15/2024]
Abstract
OBJECTIVES The aim of the study was to comprehensively analyze the effects of whey protein (WP)-enriched supplement intake with or without resistance training (RT) in older patients, either from the community or hospital, who were diagnosed with sarcopenia according to the EWGSOP or AWGS criteria. METHODS This meta-analysis study was registered in PROSPERO (CRD42023407885). We searched the PubMed, Embase, Web of Science, and Cochrane Library databases for RCTs up to June 1, 2023. Standardized mean differences (SMD) with 95% confidence intervals (CI) were used to estimate the pooled results. RESULTS Ten RCT studies, including 1154 participants, were included and analyzed. The primary outcomes were the changes in muscle mass, strength, and physical performance. In WP group versus (vs.) Isocaloric placebo (PLA)/Routine consultation (RC) group, WP significantly increased the appendicular skeletal muscle mass index (SMD: 0.47, 95%CI: 0.23, 0.71), appendicular skeletal muscle mass (SMD: 0.28, 95%CI: 0.11, 0.45) and gait speed (SMD: 1.13, 95%CI: 0.82, 1.44) in older patients with sarcopenia. In WP with RT group vs. PLA/ RC group, there was significant increase in handgrip strength (SMD: 0.67, 95%CI: 0.29, 1.04). In addition, in the secondary outcomes, WP significantly reduced interleukin-6, significantly increased insulin-like growth factor-1 and albumin, promoted participants' intake of total energy and protein, enhanced activities of daily living scores in patients, and had no significant effect on BMI, weight, or fat mass. CONCLUSION This review confirms that WP can improve various aspects of older adult with sarcopenia, thereby enhancing their overall physical condition. More studies should be conducted to validate this result and further explore the effects of WP and RT in patients with sarcopenia.

Abstract
PURPOSE This study aims to elucidate the dose-dependent effect of coenzyme Q10 supplementation (CoQ10) on exercise-induced muscle damage (EIMD), physical performance, and oxidative stress in adults. METHODS A systematic search was conducted through PubMed, Scopus, and ISI Web of Science databases up to August 2023, focusing on randomized control trials (RCTs) that investigated the effects of CoQ10 supplementation on EIMD recovery, physical performance and oxidative stress mitigation in adults. The weighted mean difference (WMD) and 95 % confidence interval (95 %CI) were estimated using the random-effects model. RESULTS The meta-analysis incorporated 28 RCTs, encompassing 830 subjects. CoQ10 supplementation significantly decreased creatine kinase (CK) (WMD: -50.64 IU/L; 95 %CI: -74.75, -26.53, P < 0.001), lactate dehydrogenase (LDH) (WMD: -52.10 IU/L; 95 %CI: -74.01, -30.19, P < 0.001), myoglobin (Mb) (WMD: -21.77 ng/ml; 95 %CI: -32.59, -10.94, P < 0.001), and Malondialdehyde (MDA) (WMD: -0.73 μmol/l; 95 %CI: -1.26, -0.20, P = 0.007) levels. No significant alteration in total antioxidant capacity was observed post-CoQ10 treatment. Each 100 mg/day increase in CoQ10 supplementation was correlated with a significant reduction in CK (MD: -23.07 IU/L, 95 %CI: -34.27, -11.86), LDH (WMD: -27.21 IU/L, 95 %CI: -28.23, -14.32), Mb (MD: -7.09 ng/ml; 95 %CI: -11.35, -2.83) and MDA (WMD: -0.17 μmol/l, 95 %CI: -0.29, -0.05) serum levels. Using SMD analysis, "very large" effects on LDH and "moderate" effects on CK and MDA were noted, albeit nonsignificant for other outcomes. CONCLUSION CoQ10 supplementation may be effective in reducing biomarkers of EIMD and oxidative stress in adults. Nevertheless, given the preponderance of studies conducted in Asia, the generalizability of these findings warrants caution. Further RCTs, particularly in non-Asian populations with large sample sizes and extended supplementation durations, are essential to substantiate these observations.

Maroni TD, Siddall AG, Rue CA, Needham-Beck SC, Walker FS, Greeves JP, Wardle SL, Fieldhouse A, Myers SD, Blacker SD. Beyond change scores: Employing an improved statistical approach to analyze the impact of entry fitness on physical performance during British Army basic training in men and women. Scand J Med Sci Sports 2024; 34:e14610. [PMID: 38534053 DOI: 10.1111/sms.14610] [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: 09/26/2023] [Revised: 03/08/2024] [Accepted: 03/11/2024] [Indexed: 03/28/2024]
Abstract
The aim was to use a robust statistical approach to examine whether physical fitness at entry influences performance changes between men and women undertaking British Army basic training (BT). Performance of 2 km run, seated medicine ball throw (MBT) and isometric mid-thigh pull (MTP) were assessed at entry and completion of Standard Entry (SE), Junior Entry-Short (JE-Short), and Junior Entry-Long (JE-Long) training for 2350 (272 women) recruits. Performance change was analyzed with entry performance as a covariate (ANCOVA), with an additional interaction term allowing different slopes for courses and genders (p < 0.05). Overall, BT courses saw average improvements in 2 km run performance (SE: -6.8% [-0.62 min], JE-Short: -4.6% [-0.43 min], JE-Long: -7.7% [-0.70 min]; all p < 0.001) and MBT (1.0-8.8% [0.04-0.34 m]; all p < 0.05) and MTP (4.5-26.9% [6.5-28.8 kg]; all p < 0.001). Regression models indicate an expected form of "regression to the mean" whereby test performance change was negatively associated with entry fitness in each course (those with low baseline fitness exhibit larger training improvements; all interaction effects: p < 0.001,η p 2 $$ {\eta}_{\mathrm{p}}^2 $$ > 0.006), particularly for women. However, when matched for entry fitness, men displayed considerable improvements in all tests, relative to women. Training courses were effective in developing recruit physical fitness, whereby the level of improvement is, in large part, dependent on entry fitness. Factors including age, physical maturity, course length, and physical training, could also contribute to the variability in training response between genders and should be considered when analyzing and/or developing physical fitness in these cohorts for future success of military job-task performance.

Effects of photobiomodulation applied at different times on functional performance and ergogenic response of rugby athletes: Randomized clinical trial. J Bodyw Mov Ther 2024; 38:314-322. [PMID: 38763575 DOI: 10.1016/j.jbmt.2023.11.052] [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: 03/20/2023] [Revised: 09/25/2023] [Accepted: 11/24/2023] [Indexed: 05/21/2024]
Abstract
BACKGROUND Photobiomodulation (PBM) is indicated to accelerate the recovery of athletes and reduce muscle damage caused by physical exercise. The objective of this study was to establish the best time to apply photobiomodulation to increase the functional performance and ergogenic response of rugby athletes. METHODS Randomized crossover clinical trial with 18 rugby athletes of both sexes. The interventions were carried out from January to May 2019. The blood levels of creatine kinase (CK) and lactate, and performance in the Modified Star Excursion Balance Test, Single Hop Test, Triple Hop Test, Bangsbo Sprint test (BST), and Yo-Yo intermittent recovery level 1 (YoyoIR1) were evaluated. The athletes underwent two blocks of exercises with the BST and Yoyo-IR1, as well as the random application of four interventions: without application of photobiomodulation (CO), pre-exercise photobiomodulation (PBpre), PBM during the exercise interval (PBint), or post-exercise photobiomodulation (PBpos). The photobiomodulation using light-emitting diodes (850 nm, 8 J/cm2) lasted 10 min and was applied to the quadriceps, hamstrings, and triceps surae muscles. The results were compared between groups and times, and the effect size for the interventions was established. RESULTS No differences were found between groups in CK, lactate, and performance in the functional tests between groups and times. Only the PBpre presented improved performance in the first Yoyo-1R1 test (p < 0.01), while the PBint improved in the second Yoyo-IR1 test and BST (p < 0.05). CONCLUSION The PBM did not change muscle damage markers or performance in the functional tests. For an ergogenic response, photobiomodulation applied before exercise improves performance, which can be maintained when PBM is performed in the exercise interval.

Abstract
Despite current literature pointing to a link between shortened telomeres and aging, chronic diseases, and geriatric syndromes, the precise implications of this connection remain unclear. The aim of this exploratory, cross-sectional, observational study was to investigate the association between the relative telomere length (RTL) of peripheral blood leukocyte subtypes (mononuclear cells and granulocytes) and physical performance using the Short Physical Performance Battery (SPPB) in older adults. A cohort of 95 participants was recruited, which included men and women aged over 60 years (70.48 ± 5.5 years). It was found that mononuclear cell RTL was significantly lower than that of granulocytes (p < 0.0001). Moreover, individuals with good SPPB performance exhibited lower mononuclear cell RTL compared with those with moderate or poor performance. However, no significant differences were observed in granulocyte RTL between different SPPB performance groups. The global SPPB score showed an inverse correlation with mononuclear cell RTL, but this correlation was not present with granulocyte RTL. Similarly, the SPPB sit-to-stand domain correlated with mononuclear cell RTL, but no such correlation was found with granulocyte RTL. Our findings challenge conventional expectations, suggesting that shorter mononuclear cell RTL may be associated with favorable functional capacity. The variations in RTL between mononuclear cells and granulocytes highlight their distinct biological roles and turnover rates. A history of immune responses may influence mononuclear cell RTL dynamics, while telomerase activity may protect granulocyte RTL from significant shortening. The unexpected associations observed in mononuclear cell RTL emphasize the complex interplay between immune responses, cellular aging, and functional capacity in older adults.
