Caffeine optimizes Zumba training benefits on functional performances in middle-aged women: a randomized trial study

The current study aimed to explore the effect of daily caffeine supplementation (100 mg/day) and 12-week of Zumba training on functional performances in middle-aged women. Eighty-five middle-aged women were randomized into 4 groups including control, Zumba training (ZT), caffeine supplementation (Ca) or caffeine-Zumba training (Ca + ZT) groups. Functional performances were assessed using 10 m Walk, Timed Up and Go, Functional Reach, and 30-Second Chair Stand tests. As results, ZT, Ca and Ca + ZT intervention programs showed a significant (p < 0.05) functional performances improvement. However, Ca + ZT group showed significant (p < 0.001) better scores in terms of mobility (95%CI [0.71, 1.43]), gait speed (95%CI [0.52, 1.71]) and lower body endurance strength (95%CI [-6.93, -1.92]), except for dynamic balance (95%CI [-9.41, -3.44]). In conclusion, 12-week of Zumba training improves functional performances in middle-aged women, and daily caffeine intake is an effective alternative for improving such performances. Supplementing caffeine (100 mg/day) to Zumba training was effective in boosting Zumba benefits on these functional performances.

Associations of physical activity, sedentary time, and fitness with cardiovascular risk and atherosclerosis over 3 years in women with systemic lupus erythematosus

IntroductionCardiovascular (CV) diseases are among the main causes of death in systemic lupus erythematosus (SLE). Physical activity (PA) and fitness are potential protective factors against the progression of CV risk factors and atherosclerosis. AimTo analyze trends over time in PA, sedentary time (ST) and physical fitness and their associations of with traditional and novel markers of CV risk and subclinical atherosclerosis in women with SLE over a 3-year follow-up period. MethodsIn this exploratory study, 77 White Hispanic women with SLE (43.3±13.8 years) with mild disease activity were followed after 3 years (n=44). HDL and LDL cholesterol (blood samples), BMI and muscle mass (stadiometer and bioimpedance device), blood pressure (BP), pulse wave velocity (PWV, Mobil-O-Graph® monitor), carotid plaques and intima–media thickness (General Electric Medical Systems, LOGQ-6 model) were assessed. PA and ST were measured using triaxial accelerometers. Physical fitness was assessed with the back-scratch, handgrip strength, 30-s chair stand, and 6-min walk, tests. ResultsAfter 3 years, LDL-c (estimated mean change [est]=13.77mg/dL) and PWV (0.13m/s) increased while diastolic BP (−2.80mmHG) decreased (all, p<0.05). In mixed models, 6-min walk test was positively associated with HDL-c (est=0.07); back scratch (est=0.33) and chair-stand (est=1.19) tests were positively associated with systolic BP (all, p<0.05). No other trends or associations over time were identified (all, p>0.05). ConclusionsPA, ST, fitness, and most studied CV risk factors remained stable over time, with only marginal changes in LDL-c, PWV, and diastolic BP. Overall, PA and ST were not longitudinally associated with CV risk factors and subclinical atherosclerosis and contradictory weak associations were found for physical fitness.

A single-center, double-blind, randomized, placebo-controlled, two-arm study to evaluate the safety and efficacy of once-weekly sirolimus (rapamycin) on muscle strength and endurance in older adults following a 13-week exercise program

BackgroundAging leads to a decline in muscle mass and strength, contributing to frailty and decreased quality of life. Sirolimus (rapamycin) , an mTOR inhibitor, has shown potential in preclinical studies to extend lifespan and improve health span. This study evaluates the safety and efficacy of once-weekly sirolimus (rapamycin) administration on muscle strength and endurance in older adults engaged in a 13-week exercise program.MethodsThis randomized, double-blind, placebo-controlled trial will enroll 40 participants aged 65–85. Participants will be randomly assigned to receive either sirolimus (rapamycin) 6 mg/week or placebo for 13 weeks, in conjunction with an at-home exercise program. The primary outcome measure is the change in muscle strength and endurance, assessed by the 30-Second Chair-Stand Test. Secondary outcome measures include adverse events, changes in muscle strength and endurance as measured by the 6-min walk test, handgrip strength, and participant-reported outcomes using the SF-36 survey. Assessments will be conducted at baseline, mid-intervention (week 6), and post-intervention (week 13). Blood samples will be collected for hematology and biochemistry analyses, including full blood count, urea and electrolytes, liver function tests, HbA1c, lipids, serum IGF-1, and hs-CRP. DNA methylation will be analyzed using TruDiagnostic™ to explore changes in biological age.DiscussionThis study aims to provide insights into the potential benefits of intermittent sirolimus (rapamycin) administration on muscle performance in older adults. By alternating periods of mTOR inhibition through rapamycin and activation via exercise, this study will explore a novel approach to enhancing muscle strength and endurance in the aging population. The results could have significant implications for developing interventions to improve physical function and overall health outcomes in older adults. Safety and tolerability will also be closely monitored to ensure the feasibility of this regimen for wider application.Trial registrationAustralia New Zealand Clinical Trials Registry, ACTRN12624000790549.

Transition of Physical, Psychological, and Cognitive Frailty and Its' Associated Determinants in Malaysian Older Adults: A 5-Year Follow-up Study.

Frailty, a multifaceted syndrome, affects approximately 26% of older adults globally, yet there are limited data on the prevalence and longitudinal impact of frailty subtypes. Therefore, in this study, we aim to determine the prevalence of physical, psychological, and cognitive frailty, transitions between subtypes, and associated health determinants among Malaysian community-dwelling older adults. This study is part of the longitudinal aging study in Malaysia (LRGS Ageless and TUA). We assessed 815 older adults in 2014, with successful follow-up of 402 participants (mean age: 67.08 ± 5.38 years) after 5 years. Frailty subtypes were assessed at baseline, and transitions were evaluated at the 5-year mark. At baseline, the prevalence of older adults categorized as robust, physical frailty, cognitive frailty, and psychological frailty was 26.7%, 36.3%, 12.1%, and 16.7%, respectively, with 8.1% exhibiting concurrent psychological and cognitive frailty. Follow-up results showed that 22.9% remained robust, 46.8% experienced no change, 24.9% deteriorated (adversed), and 5.5% improved (reversed). Logistic regression analysis identified living alone (p < 0.001), increased body fat percentage (p < 0.05), increased waist circumference (p < 0.05), reduced fat-free mass (p < 0.05), decreased lower limb flexibility (p < 0.05), and declined cardiorespiratory fitness (p < 0.05) as significant predictors of frailty deterioration. Higher Mini Mental State Examination (MMSE) scores and improved Timed Up and Go and Chair Stand test results (p < 0.05) were significantly associated with the reversal of frailty subtypes (p < 0.05). Younger older adults (p < 0.001), males (p < 0.05), those with lower WHO Disability Scale scores (p < 0.05), and higher MMSE scores (p < 0.05) were significantly less likely to develop frailty subtypes. Intervention strategies that focus on combined physical, cognitive, and psychosocial functions are crucial for both reversing and preventing the progression of frailty subtypes in older adults.

Association of Gut Microbiome with Muscle Mass, Muscle Strength, and Muscle Performance in Older Adults: A Systematic Review.

Sarcopenia, characterized by reduced muscle mass, strength, or performance, is a common condition in older adults. The association between the gut microbiome and sarcopenia remains poorly understood. This systematic review aims to evaluate the relationship between muscle parameters and the intestinal microbiome. A systematic search was conducted in PubMed, EMBASE, Cochrane Library, and Google Scholar for studies published between 2002 and 2022 involving participants aged 50+. Studies were included if they assessed sarcopenia using at least one measure of muscle mass (skeletal muscle mass, bioelectrical impedance analysis, MRI), muscle strength, or muscle performance (SARC-F questionnaire, Timed-Up-and-Go Test, Chair Stand Test, grip strength, gait speed, Short Physical Performance Battery, 400 m Walk Test). The microbiome was measured using at least RNA/DNA sequencing or shotgun metagenomic sequencing. Twelve studies were analyzed. Findings revealed that a higher abundance of bacterial species such as Desulfovibrio piger, and Clostridium symbiosum and reduced diversity of butyrate-producing bacteria was associated with sarcopenia severity, as indicated by decreased grip strength, muscle mass, or physical performance. The gut microbiome plays a significant role in age-related muscle loss. Probiotics, prebiotics, and bacterial products could be potential interventions to improve muscle health in older adults.

Developing an 8-Week, Tele-Education Weight Control and Exercise Programme, and Evaluating Its Effects on Weight and Pain Reduction in Patients With Obesity and Knee Osteoarthritis: A Double-Blinded Randomised Clinical Trial.

Knee osteoarthritis (OA) is a leading cause of disability among the elderly and is often exacerbated by obesity. Research supports weight loss and exercise therapy as key strategies for managing knee OA-related disability. Concurrently, telemedicine is becoming a popular healthcare approach. This study aimed to develop and evaluate an 8-week tele-education programme's impact on weight control and knee OA outcomes. Participants with knee OA and obesity were included. Baseline data on pain (VAS index), physical activity (GPAQ questionnaire), and quality of life (EQ5D and KOOS questionnaires) were collected. Performance tests, including the 30-second Chair Stand test (30CST) and the Timed Up-and-Go test (TUG), were recorded. Participants were randomly divided into two groups: a control group receiving oral advice on diet and exercise, and an intervention group receiving educational videos on nutrition, lifestyle changes, physical activity, individualised exercises, and psychosocial support. Evaluations were repeated after 8weeks. Data from 25 of 30 participants were analysed. In the intervention group, body composition, waist, and abdominal circumference decreased significantly (p<0.05). The KOOS questionnaire showed significant improvements in pain, activity, and daily tasks (p=0.00). The EQ5D questionnaire and health satisfaction also showed positive results within the intervention group (p=0.00) and between groups (p=0.008). The pain index improved significantly within (p=0.00) and between groups (p=0.02). Functional test results were significant within the intervention group (p=0.00) and between groups (p=0.017 for 30CST and p=0.004 for TUG). An 8-week tele-education programme for weight control and exercise therapy in knee OA patients significantly improved body composition, quality of life, and functional performance. Given the costs of obesity and knee OA on both people and the health system, tele-education can be a cost-effective treatment strategy.

A cardiac rehabilitation programme based on neuromuscular training improves the functional capacity of patients with acute coronary syndrome: a preliminary randomised controlled trial

ObjectivesTo evaluate the effects of a cardiac rehabilitation programme based on neuromuscular training (NMT) compared with classic rehabilitation strength training (CRST) in patients diagnosed with acute coronary syndrome (ACS). DesignPreliminary randomised, double-blinded, parallel clinical trial. SettingUniversity health clinic in Valencia, Spain. ParticipantsThirty patients with ACS, InterventionsPatients were assigned to one of two groups at random: the NMT group (n=15) and the CRST group (n=15). All patients attended the 20 sessions of the exercise programme. Main outcome measuresThe primary outcome was the Incremental Shuttle Walk Test (ISWT). The secondary outcomes were the Chester Step Test (CST), the 30-Second Chair Stand Test (30CST), and hip flexor dynamometry. Assessments were made at baseline, immediately post-treatment, and at 6-month follow-up. ResultsThe NMT group showed a greater improvement in the ISWT than the CRST group, both at post-treatment {mean 648 [standard deviation (SD) 197] vs 493 (SD 219), mean difference 155, 95% confidence interval (CI) -1 to 310} and at follow-up [732 (SD 183) vs 518 (SD 222), mean difference 214, 95% CI 61 to 367]. The secondary outcomes showed significant between-group differences in favour of the NMT group at 6-month follow-up, except for the 30CST. ConclusionsThese preliminary findings indicate that a cardiac rehabilitation programme based on NMT may improve functional capacity in terms of patient performance, cardiorespiratory fitness and muscle strength. Moreover, the improvements were maintained at medium-term follow-up. This could help improve the design of rehabilitation sessions, considering factors associated with performing everyday activities in patients affected by ACS.

BIA-assessed cellular hydration and strength in healthy older adults

ObjectivesThe objective of this research was to evaluate the differential relationships between various BIA-estimated compartments of body water and strength, among healthy older adults, by age range and sex. DesignDescriptive and correlational study. Setting and ParticipantsA total of 234 healthy older adults (72.59±7.60 years) participated in the study. Participants were recruited from community centers around Portugal and Spain. Data were recorded during May 2023. This is a physically active sample: all the participants are physically active for a minimum of three days a week. MethodsFor the study of body composition the variables extracted from the Tanita were: fat mass (FM), fat free mass (FFM), visceral fat rating (VFR), total body water (TBW), extracellular water (ECW) and intracellular water (ICW). Handgrip Strength was used to evaluate upper body strength and the Chair Stand Test for lower body strength. ResultsDifferences across the various data sets were recorded in the gender variable.When looking into the gender variable, significant correlations were recorded for the body composition variables analyzed for all age groups in the upper body strength test, except for BMI(r=0.125-0.878) and Fat mass (0.056 - -0.634). For the lower body strength test, no significant correlations were recorded for the Fat-Free mass variables (r= 0.164 - 0.380), as well as for the Visceral Fat Rating(r= 0.082 - 0.213) and the body water variables (TBW, ECW, ICW). ConclusionsThe hydration parameters analyzed can be related to muscle performance for Handgrip in an independent older adult population with ages ranging from 60 to 90 years.

Prevalence and Diagnostic Agreement of Sarcopenia Based on Handgrip Strength and 5-Time Chair-Stand Test Among Chinese Community-Dwelling Older Adults.

Handgrip strength and the 5-time chair-stand test are the two important muscle strength measures run through the whole sarcopenia diagnosis algorithm. There is a lack of evidence to confirm which muscle strength measures have a higher detection rate of sarcopenia among Chinese older adults, which is a challenge for community workers to choose the muscle strength measures and to identify more sarcopenia in clinical practice. We aimed to investigate the prevalence and diagnostic agreement of sarcopenia based on handgrip strength and the 5-time chair-stand test among Chinese community-dwelling older adults. This cross-sectional study sampled 1027 community-dwelling older adults from Hunan, China. We used handgrip strength and the 5-time chair-stand test to assess participants' muscle strength and used gait speed and bioimpedance analysis (BIA) to assess physical performance and skeletal muscle mass, respectively. The kappa values of the agreement test were used to evaluate the agreement of handgrip strength and 5-time chair-stand tests in the assessment of sarcopenia. A total of 1027 participants were included in this analysis including 337 males and 690 females with an average age of 70.35 ± 7.24 years. The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was 50.8%, 20.3% and 14.5% respectively, while the corresponding prevalence for using the 5-time chair-stand test was 27.6%, 10.8% and 10.9%. The kappa value of the consistency test between handgrip strength and 5-time chair-stand test in the assessment of possible sarcopenia, confirmed and severe sarcopenia was 0.26, 0.51 and 0.62, respectively (p < 0.001 for all). The prevalence of possible sarcopenia, confirmed sarcopenia and severe sarcopenia based on handgrip strength was significantly higher than that of the 5-time chair-stand test. We recommend handgrip strength as the preferred method of muscle strength measurement for Chinese community-dwelling older adults and use 5-time chair-stand tests when handgrip strength is not available. The findings provide information and suggestions to healthcare providers for choosing the muscle strength measures to detect more sarcopenia in clinical practice. Compared with the 5-time chair-stand test, handgrip strength has a better performance to identify sarcopenia in Chinese community-dwelling older adults.

Thirty seconds chair stand performance is associated with six-minute walk test among postmenopausal women: inference from a cross-sectional study among women from India

Menopause is an inevitable yet normal biological process in a woman’s life. The menopausal process has been associated with a decline in muscle strength and functional capacity. Thus, the present study aimed to study the association of the 30-Second Chair Stand Test (30s CST) with the 6-Minute Walk Test (6MWT) among postmenopausal women. Thirty-five postmenopausal women aged 40–55 years were included in this cross-sectional study by purposive sampling method. After initial screening and assessment 30s CST and 6MWT were recorded as per standardised guidelines. The mean and Standard Deviation (SD) for all continuous variables was calculated. Correlations were estimated using Pearson’s coefficient of correlation. A two-tailed p-value &lt;0.05 was considered statistically significant. There exists a significant positive association of 30s CST values with 6MWD among postmenopausal women. Also, the Rate of Perceived Exertion (RPE) scores after the 6MWT were found to be significantly correlated with RPE scores after 30s CST. In conclusion, there exists a significant positive correlation of 30s CST with 6MWT among postmenopausal women. The 30s CST could be used as an economical and quick physical function assessment measure among postmenopausal women in low-resource settings.

The work Lifestyle-integrated Functional Exercise program for preventing functional decline in employees aged 55 years and older: development and initial evaluation

BackgroundDespite the global increase in older employees, workplace physical activity interventions (WPAIs) for this target group have not yet been sufficiently developed. The major drawback of existing WPAIs is low adherence due to lack of time or limited motivation. A novel approach could be to integrate tailored neuromotor and strength exercises into everyday working tasks to prevent the functional decline of older employees at the workplace without needing much additional time for training. This approach was tested in the present study by evaluating the proof-of-concept of a novel WPAI based on the Lifestyle-integrated Functional Exercise (LiFE) program integrated into a working environment (wLiFE55 +).MethodsThe proof-of-concept of wLiFE55 + was quantified within a 4-week pre-post exercise intervention study by measuring (1) feasibility including adherence, activity frequency, adverse events and acceptance (integrability of wLiFE55 + activities, perceived improvement and safety, satisfaction, physical demand, personal trainer session, intervention content) and (2) pre-to-post changes in neuromotor function (12-Level Balance Scale, 12-LBS; Community Balance and Mobility Scale, CBM), strength (60sec Chair Stand Test), and PA (1-week activity monitoring). For statistical analysis, the median and interquartile range (IQR) were computed. For pre-to-post changes, Wilcoxon signed-rank tests with effect size (r) were also performed.ResultsSeventeen older employees (mean age 59 years, 8 female) were included of which fifteen completed the study. The intervention adherence was 100%, and the activity adherence was 58% (9 out of 12 maximum possible wLiFE55 + activities implemented). Depending on the specific activity, the frequency of practice ranged between 25–75% of the days of the intervention period, and single wLiFE55 + activities were practiced between one and three times per day. No adverse events occurred, and acceptance was high. Pre-to-post increases with medium effect sizes were found for neuromotor function (CBM, 12-LBS) and specific PA variables (total sedentary time, sedentary bouts > 30 min).ConclusionThe results of the study highlight the feasibility of wLiFE55 + in a work setting with older employees. The pre-to-post increases observed in neuromotor measures and reductions in sedentary time suggest that wLiFE55 + may counteract the age-related functional decline in older employees and justifies future studies in this field. The next steps are program adjustments to boost exercise frequency and evaluating wLiFE55 + in a randomized controlled trial.

The Risk of Malnutrition and Sarcopenia in Elderly People Living with HIV during the COVID-19 Pandemic.

Malnutrition is a risk factor of sarcopenia in the elderly. During the COVID-19 pandemic, limited transportation and supply chain disruptions restricted access to nutritious foods. We assessed the nutritional status and sarcopenia risk in older people living with HIV (PLWH) on combination antiretroviral therapy in Thailand. This study was a hospital-based cohort among virally suppressed older PLWH who came for routine HIV clinic visits. The mini nutritional assessment (MNA), body composition analysis and 5-time chair stand test (CST) were performed to assess the nutritional status, muscle mass and physical performance, respectively. A total of 177 PLWH were enrolled (57.60% male). The median age was 58 years (IQR 55-62 years). Thirty-five participants (19.8%) were at risk of developing sarcopenia, and 28.2% had abnormal nutritional status. Muscle mass correlated positively with nutritional scores (r = 0.355, p < 0.001) but negatively with 5-time CST duration (r = -0.173, p = 0.021). In the multivariate model, muscle mass was associated with age, sex, mid-arm circumference, calf circumference and 5-time CST duration. In a well-viral-suppressed older Asian PLWH cohort, given the positive correlation between nutritional status and muscle mass, the nutritional status of older PLWH should be routinely evaluated and monitored.

Impact of Classical Music Listening on Cognitive and Functional Performances in Middle-Aged Women

The purpose of this study was to examine the impact of listening to classical music on functional (upper and lower body strength, functional mobility and aerobic endurance) and cognitive (attentional capacities and working memory (WM)) performances in women aged between 50 and 60 years old. A total of 24 middle-aged women were enrolled to participate in this study. Their functional and cognitive performances were assessed under two-auditory conditions (no-music vs. with music conditions) using the Timed Up and Go (TUG) test for functional mobility, the Arm Curl test and 30 s Chair Stand Tests for the upper and lower body strength, respectively, and the 2 min Step test for aerobic endurance. To assess the attentional capacities and the WM, a simple reaction time (SRT) test and Corsi Block-Tapping Task were used, respectively. As a result, we found that listening to music significantly decreased the scores of the TUG test (p &lt; 0.001) and capacities (p &lt; 0.05), and increased the 2 min Step test values (p &lt; 0.001) compared to the no-music condition. However, no significant changes were found for the upper and lower body strength and WM. We conclude that listening to classical music, i.e., Mozart’s Symphony, is effective in improving functional mobility, aerobic endurance and attentional capacities in middle-aged women. However, these gains were absent for muscle strength and WM, suggesting that the positive effects of music on functional and cognitive performances were dependent on a specific task.

Effects of Proprioceptive Neuromuscular Facilitation Technique on Balance Function and Muscle Health in Older Adults With High Fall Risk.

Older adults frequently encounter health challenges, such as impaired balance and muscle health, which increase risk of falls. The current study investigated the effectiveness of the proprioceptive neuromuscular facilitation (PNF) technique in improving balance and muscle health among older adults with high fall risk. A total of 160 older adults with high fall risk were randomized into control and intervention groups. Over 6 months, the control group received standard interventions, while the intervention group received the same interventions and additional PNF training. Both groups demonstrated improvements in balance function over time, with the intervention group exhibiting significant improvements in Berg Balance Scale scores, Timed Up and Go test times, and 30-Second Chair Stand Test counts (p < 0.05). Bone density significantly increased in the intervention group compared to the control group (p < 0.05), although no substantial differences in lower limb muscle mass were observed. Satisfaction rates were higher and fall incidents fewer in the intervention group. The PNF technique is effective in enhancing balance function and muscle health in older adults with high fall risk, demonstrating potential in reducing fall risk and improving quality of life among older adults.

The Effect of Suspension Training and Dumbbell Training on Increasing Muscle Endurance in the Elderly

Abstract To determine the difference in the provision of suspension training and dumbbell training on increasing muscle endurance in the elderly. This study is experimental which was conducted 2 times a week for 4 weeks at Perkumpulan Senam Lansia Kelurahan Cibubur. This study consisted of 20 people and was divided into two groups of 10 people each, namely treatment group I given Suspension Training and treatment group II given Dumbbell Training. Each group of muscle endurance improvement was measured with the Arm (Biceps) Curl Test and 30 Second Chair Stand Test. This research is experimental which was conducted 2 times a week for 4 weeks at Perkumpulan Senam Lansia Kelurahan Cibubur. This study consisted of 20 people and was divided into two groups of 10 people each, namely treatment group I given Suspension Training and treatment group II given Dumbbell Training. Each group increased muscle endurance measured by the Arm (Biceps) Curl Test and 30 Second Chair Stand Test. Results: In this study successfully showed that Suspension Training pre test ACBT mean ± SD is 18.60 ± 4.138, the results of the post test ACBT mean ± SD is 19.90 ± 4.202. Pre test 30s CST mean ± SD is 11.60 ± 1.838, the results of the post test 30s CST mean ± SD is 13.20 ± 2.486. In the Dumbbell Training study, the results of the ACBT pre test mean ± SD were 18.50 ± 4.275, the results of the ACBT post test mean ± SD were 19.50 ± 4.552. Pre test 30s CST mean ± SD is 11.40 ± 2.547, the results of the post test 30s CST mean ± SD is 12.40 ± 2.271. Both of these studies showed a significant increase in muscle endurance in the elderly between before and after treatment (p &lt; 0.05). However, the difference test between Suspension Training and Dumbbell Training on increasing muscle endurance did not show a significant difference (p = 0.273). Suspension Training and Dumbbell Training can significantly increase muscle endurance in the elderly but the two methods do not show a significant difference in the results.

The efficiency of Ram Thai with Nine Square dance on physical performance and cognitive functions: a model for elderly school

Age-related declines in health-related physical fitness and cognitive function can be mitigated by a multi-movement exercise program. Therefore, the aim of this study was to determine the efficiency of Ram Thai with nine square dances on physical performance and cognitive functions in the elderly. Participants were randomly assigned into an experimental or control group. The Montreal cognitive assessment-basic (MoCA-B, Thai version) were chosen from screened volunteers and randomly assigned into 2 groups; Ram Thai with nine square dances (RTND:33) and brisk walking exercise (BWE:34) aged 65.3±2.4 years old, body mass index (BMI) 25.5±11.9 kg/m2. The physical performance parameters assessed were as follows: Back-scratch test (BST), Chair sit and reach test (CSRT), Chair stand test (CST), 30-second arm curl test (ACT), 6-minute walk test (6-WT) and timed up and go test (TUG) were conducted respectively. Our results showed the physiological revealed a reduction in body fat percentage, while significant increase in VO2max test scores observed in both groups (p≤.05). Additionally, there was an improved lower limb strength, as evidenced by statistically significant increases in scores for the CST, 6-WT, and TUG compared to pretest values (p≤.05). In terms of BST performance, the RTND group showed significantly better results compared to the BWE group (p≤.001). Moreover, we discovered that significantly superior results indicate increased variability in MoCA-B scores (24.11≈26.37) among elderly participants in the RTND group (p≤.001). The data indicates that RTND effectively enhances physiological aspects, physical performance control, and overall cognitive function in elderly individuals with mild cognitive impairment (MCI). Keywords: physical performance, cognitive function, mild cognitive impairment, elderly

Factors associated with lower quarter performance-based balance and strength tests: a cross-sectional analysis from the project baseline health study.

Physical performance tests are predictive of mortality and may screen for certain health conditions (e.g., sarcopenia); however, their diagnostic and/or prognostic value has primarily been studied in age-limited or disease-specific cohorts. Our objective was to identify the most salient characteristics associated with three lower quarter balance and strength tests in a cohort of community-dwelling adults. We applied a stacked elastic net approach on detailed data on sociodemographic, health and health-related behaviors, and biomarker data from the first visit of the Project Baseline Health Study (N = 2,502) to determine which variables were most associated with three physical performance measures: single-legged balance test (SLBT), sitting-rising test (SRT), and 30-second chair-stand test (30CST). Analyses were stratified by age (<65 and ≥65). Female sex, Black or African American race, lower educational attainment, and health conditions such as non-alcoholic fatty liver disease and cardiovascular conditions (e.g., hypertension) were consistently associated with worse performance across all three tests. Several other health conditions were associated with either better or worse test performance, depending on age group and test. C-reactive protein was the only laboratory value associated with performance across age and test groups with some consistency. Our results highlighted previously identified and several novel salient factors associated with performance on the SLBT, SRT, and 30CST. These tests could represent affordable, noninvasive biomarkers of prevalent and/or future disease in adult individuals; future research should validate these findings.

Optimizing Total Knee Arthroplasty Rehabilitation With Telehealth Physical Activity Behavior Change Intervention: A Randomized Clinical Trial.

Conventional total knee arthroplasty (TKA) rehabilitation has little impact on sedentary lifestyles that have negative long-term health consequences. The purpose of this trial was to determine the effect of telehealth-based physical activity behavior change intervention on physical activity and functional outcomes following TKA. This study was a 2-arm, parallel randomized controlled superiority trial at a regional Veterans Affairs medical center. The participants were 92 US military veterans (mean age = 65.7 [SD =7.8] y) undergoing unilateral TKA. The Physical Activity Behavior Change (PABC) intervention included telehealth-based self-management training (10 30-minute sessions) delivered over 12weeks. The control intervention included telehealth-based health education sessions that matched PABC frequency and duration. Both groups participated in standardized conventional outpatient rehabilitation. Physical activity, measured as average daily step count, was the primary outcome. Secondary outcomes were Life-Space Assessment questionnaire, 30-Second Chair-Stand test, Timed "Up & Go" Test, 6-Minute Walk Test, Western Ontario and McMaster Universities Osteoarthritis Index, and Veterans RAND 12-Item Health Survey. The Self Efficacy for Exercise scale and daily time spent in different postures (sitting/lying, standing, stepping) were exploratory variables. Outcomes were measured at baseline (before surgery), mid-intervention (8weeks after surgery), after the intervention (14weeks after surgery; primary endpoint), and follow-up (38weeks after surgery). The PABC group had an estimated 931 (95% CI = 42-1819) more daily steps than the control group from baseline to 14weeks, though a between-group effect was not sustained at 38weeks. There were no group differences in secondary outcomes. Participants included only military veterans using Veterans Health Administration services. The intervention targeted self-management and did not include peer support. The PABC intervention improved physical activity for veterans recovering from unilateral TKA at 14weeks after surgery, though the effect was not sustained at 38weeks. Physical function improved with rehabilitation but was not different between groups, indicating that physical function was not a primary driver of physical activity behavior. Conventional TKA rehabilitation has a negligible effect on free-living physical activity, which is relevant to long-term health outcomes. This trial identified telehealth physical activity self-management as effective in addressing activity behaviors, separate from conventional rehabilitation strategies.

Timed up and go and 30-S chair-stand tests applied via video call are reliable and provide results similar to face-to-face assessment of older adults with different musculoskeletal conditions

BackgroundRemote assessments are promising for coping with adverse situations, such as those imposed by the COVID-19 pandemic. Measurement properties must be specific to the characteristics of the population and the context in which the instruments are used. Purposes: 1) To evaluate the parallel reliability of the timed up and go (TUG) and 30-s chair-stand test (30CST) performed in-person and remotely and 2) to analyze the intra-rater, inter-rater, and test-retest reliability of these tests assessed remotely in older adults with different musculoskeletal conditions. MethodsThe sample included 50 older adults. Parallel reliability was determined by comparing in-person and remote data. Bland-Altman plots displayed differences between tests (TUG and 30CST) performed in-person and remotely, showing the mean scores of each participant. The intra-rater, inter-rater, and test-retest reliability for remote assessments were analyzed using the intraclass correlation coefficient (ICC) with a 95% confidence interval. ResultsParallel reliability was high between in-person and remote assessments (ICC >0.82). Intra-rater, inter-rater, and test-retest reliability were very high for remote assessments (ICC >0.90). The minimal detectable change for the remote assessment of TUG (MDC <1.95) and 30CST (MDC <2.39) indicated adequate sensitivity. In both tests, the standard error of the measurement was acceptable (SEM% < 10%) and Bland-Altman limits of agreement were solid. ConclusionsThe remote assessment of TUG and 30CST in older adults with different musculoskeletal conditions was as reliable as those performed in person and may be considered when in-person assessments are impossible.
