Acceptability and utility of a broad test battery to evaluate physical functioning and frailty in community-based settings for people experiencing homelessness and addiction–Findings from the LEAP trials

BackgroundPhysical function deficits and frailty are commonly reported in people experiencing homelessness and addiction. Typically, geriatric, or general physical performance measures are employed to evaluate these constructs. Objectives and settingWe aimed to investigate the feasibility of a broad test battery to evaluate physical functioning and frailty in a non-geriatric community-based population of people experiencing homelessness and addiction. Design and methodsPhysical function and the presence of frailty was evaluated using combined data from two linked low-threshold exercise pre-post intervention studies (LEAP I and II). ParticipantsSeventy-four participants attending an open-access day-service centre (18 to 65 years) were evaluated. Participants with acute confusion or behavioural issues, or major medical condition precluding safe participation were excluded. InterventionA broad test battery was performed which evaluated physical functioning and frailty. Main outcome measuresOutcome measures included were the Short Physical Performance Battery, Single Leg Stance, Chair Stand Test, 10 m and 2 minute Walk Tests, limb circumference, dynamometry, Clinical Frailty Scale, SHARE-Frailty Instrument, numerical pain rating and Short Form-12. ResultsTest completion was 100% for all outcomes except pain rating (81% and 79% for LEAPI and II, respectively), and balance and walking tests (95% and 93% in LEAP II). A ceiling effect was detected for the Short Physical Performance Battery. ConclusionHigh feasibility of the test batteries was demonstrated. An optimised test battery was proposed based on findings. This has important implications for clinicians working in inclusion health settings. Clinical Trial Registration NumberClinical Trials.gov: NCT05700305. Contribution of the Paper•This paper proposes a suitable test battery to enable clinicians to evaluate physical functioning and frailty in people experiencing homelessness and addiction challenges in community settings.•There is a paucity of research evaluating outcome measures for this population and no core outcome set has been reported.•This test battery would allow the effect of treatment and targeted interventions to be evaluated in this marginalised population.

Strong association between sarcopenia and visceral fat in the long term after cholecystectomy: A cross-sectional study using the ISarcoPRM algorithm.

Cholecystectomy generally has no adverse effects on health. Studies demonstrating the association between metabolic diseases and long-term effects of cholecystectomy are increasing. preperitoneal fat thickness (PFT) is an important indicator of metabolic syndrome. Metabolic syndrome is a risk factor for sarcopenia. The aim of our study was to investigate the relationship between cholecystectomy and sarcopenia-visceral fat using the ISarcoPRM algorithm, which is an easy, reliable, and inexpensive method based on ultrasound measurement, to evaluate sarcopenia in patients with long-term previous cholecystectomy. This cross-sectional study included participants who had undergone cholecystectomy at least 5 years ago and a control group with similar characteristics. Sarcopenia was assessed using the ISarcoPRM algorithm, incorporating the sonographic thigh adjustment ratio (STAR), grip strength, and chair stand test (CST). Together with low STAR values (<1.0 for females and <1.4 for males), ow grip strength (<19 kg for females or <32 kg for males), and/or prolonged CST duration (≥12 seconds) were used to diagnose sarcopenia. Ultrasound was used to measure the visceral fat thickness. The investigation of sarcopenia and PFT values between individuals with and without cholecystectomy was planned. A total of 158 participants were included, including 89 post-cholecystectomy patients and 69 controls. Binary regression analysis revealed that cholecystectomy was positively associated with sarcopenia (OR = 2.788, 95% CI: 1.054-7.375, P = .039). However, when PFT was included, it was independently associated with sarcopenia (OR = 1.157, 95% CI: 1.067-1.254, P < .001), and the relationship with cholecystectomy disappeared (P > .05). PFT values of 10.0 mm or higher were associated with 5.875 times (95% CI: 2.035-16.961, P = .001) increased odds of sarcopenia. Sarcopenia was 2.8 times more frequent in patients who had undergone cholecystectomy than in those who had not, but this relationship was mediated by increased PFT. The risk of sarcopenia increased up to 5.875 times when the PFT exceeded 10 mm.

Correlation between fall experience and life functions among community-dwelling older adults in Japan

PurposeThis study investigated the correlation between the risk of falls and life functions, including motor function, cognitive function, and urinary disorders, among older adults residing in small cities in the metropolitan areas of Japan and evaluated the contents of fall prevention instructions. MethodsSixty-nine older adults residing at home participated in this case-control study conducted between September and October 2019. The survey items included questions pertaining to the history of falls; grip strength; the 30-s Chair Stand Test (CS-30), Functional Reach Test (FRT), and Timed Up and Go Test (TUG) scores; mental and cognitive functions [Test Your Memory-Japanese version test (TYM-J)]; living conditions; and urination status [Core Lower Urinary Tract Symptom Score (CLSS)]. ResultsParticipants with a history of falls had significantly lower CS-30 and FRT scores, and significantly higher TUG scores and CLSS than those with no history of falls. Grip strength bore significant correlations with the CS-30 and TUG scores. The CS-30 scores were correlated with the FRT and TUG scores. The FRT scores were correlated with the TUG and French State Activity Index (FAI) scores. The TUG scores were correlated with the TYM-J and FAI scores. The CLSS showed no significant correlations with the remaining items. The FRT scores and CLSS exerted a significant effect on the risk of experiencing falls. ConclusionBoth balancing ability and micturition status affect fall risk and should be considered in treatment strategies for urinary disorders in fall prevention programs for older adults.

Comparative effects of cognitive and instability resistance training versus instability resistance training on balance and cognition in elderly women

This study investigates the effects of integrated instability resistance training and cognitive training (IRCT) versus isolated instability resistance training (IRT) on balance, gait, muscle strength, and cognitive functions in elderly women.This randomized controlled trial included 36 participants, with 18 in the IRCT group and 18 in the IRT group. The sample size was estimated to achieve a statistical power of 0.95 with a large effect size (0.40; n = 12 each group). The closed-eye single-leg stand test was measured for static balance, the closed-eye stepping test, and the Timed Up and Go Test (TUGT) were measured for dynamic balance. Dual-task balance was assessed by combining the TUGT with cognitive tasks (TUGT-C) and motor tasks (TUGT-M). Gait performance was evaluated using a gait function system. Lower limb muscle strength was measured with the 30-Second Chair Stand Test. Cognitive function was assessed through the Trail Making Test (TMT), Digit Span Test (DST), Stroop Color and Word Test (Stroop), and Digit Symbol Substitution Test (DSST). Results IRCT group showed better improvements in both cognitive (p < 0.001) and motor (p = 0.812 for baseline; p < 0.001 for post-intervention) dual-task abilities, IRCT also experienced better enhancement in certain cognitive functions, particularly in the TMT (p = 0.001) and DSST (p = 0.022) compared to the IRT group. Both groups demonstrated enhancements in walking abilities as shown on selective markers of the gait performance test (p < 0.05) and leg muscle strength via 30-Second Chair (p < 0.001 for time main effect). These results suggest that combining cognitive exercises with physical training more effectively addresses the complex challenges associated with aging in women. The study highlights the potential of comprehensive training approaches in boosting health and quality of life for the elderly, with implications for developing tailored exercise programs focused on reducing fall risks and enhancing quality of life in this population.

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.

Association Between The 30-second Chair Stand Test And Single Limb Hop Tests In College Students

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.
