Home- vs gym-based exercise delivery modes of two multicomponent intensity training regimes on cardiorespiratory fitness and arterial stiffness in adults with intellectual and developmental disability during the COVID-19 pandemic - a randomized controlled trial.

Background: We compared the effects of home- vs gym-based delivery modes of two 8-week supervised multicomponent intensity training regimes on cardiorespiratory fitness and arterial stiffness in 17 adults with intellectual and developmental disability during the COVID-19 pandemic. Methods: Participants were assigned to sprint interval training or continuous aerobic training, both incorporating resistance training. The intervention started with 8-weeks of online training (M1-M2), 1-month of detraining, plus 8-weeks of gym-based training (M3-M4). Results: Peak oxygen uptake decreased from M1-M2 and increased from M2-M4. Central arterial stiffness decreased between M1-M2, and M1-M4, along with peripheral arterial stiffness. Central systolic blood pressure decreased from M1-M2 only with sprint interval training. Conclusion: Home-based training minimized the negative impact of the lockdown on central arterial stiffness and central blood pressure, but it did not match the benefits on cardiorespiratory fitness and peripheral arterial stiffness of a gym-based intervention, irrespective of the multicomponent intensity training regime.

Impact on physical function of the +AGIL Barcelona program in community-dwelling older adults with cognitive impairment: an interventional cohort study.

BACKGROUND: Older adults with cognitive impairment (CI) have higher multimorbidity and frailty prevalence, lower functional status and an increased likelihood to develop dementia, non-cognitive deficits, and adverse health-related events. +AGIL, a real-world program for frail older adults in a primary care area of Barcelona, is a pragmatic, multi-component and integrated intervention implemented since 2016. It includes physical activity, nutrition, sleep hygiene, revision and adequacy of pharmacological treatment, detection of undesired loneliness and screening for CI; to improve physical function in community-dwelling older adults. We aimed to assess the + AGIL longitudinal impact on physical function among community-dwelling frail older persons with CI. METHODS: An interventional cohort study included data from all the + AGIL consecutive participants from July 2016 until March 2020. Based on the comprehensive geriatric assessment, participants were offered a tailored multi-component community intervention, including a 10-week physical activity program led by an expert physical therapist. Physical performance was measured at baseline, three and six months follow-up. The pre-post impact on physical function was assessed by paired sample t-test for repeated samples. Linear mixed models were applied to analyze the + AGIL longitudinal impact. P-values < 0.05 were considered statistically significant. RESULTS: 194 participants were included (82 with CI, based on previous diagnosis or the Mini-COG screening tool), 68% women, mean age 81.6 (SD = 5.8) yo. Participants were mostly independent in Activities of Daily Living (mean Barthel = 92.4, SD = 11.1). The physical activity program showed high adherence (87.6% attended ≥ 75% sessions). At three months, there was a clinically and statistically significant improvement in the Short Physical Performance Battery (SPPB) and its subcomponents in the whole sample and after stratification for CI [CI group improvements: SPPB = 1.1 (SD = 1.8) points, gait speed (GS) = 0.05 (SD = 0.13) m/s, Chair stand test (CST)=-2.6 (SD = 11.4) s. Non-CI group improvements: SPPB = 1.6 (SD = 1.8) points, GS = 0.08 (SD = 0.13) m/s, CST=-6.4 (SD = 12.1) seg]. SPPB and gait speed remained stable at six months in the study sample and subgroups. CI had no significant impact on SPPB or GS improvements. CONCLUSION: Our results suggest that older adults with CI can benefit from a multidisciplinary integrated and comprehensive geriatric intervention to improve physical function, a component of frailty.

Effects of multicomponent exercise on quality of life, depression and anxiety among stroke survivors: A systematic review and meta-analysis.

BACKGROUND: Current guidelines stress the importance of exercise, especially multicomponent exercise to older adults with chronic conditions. AIM: To critically synthesise evidence that evaluates the effects of multicomponent exercise on quality of life, depression and anxiety after stroke. DESIGN: Systematic review and meta-analysis followed the PRISMA 2020 statement. METHODS: A systematic search of PubMed, Embase, Web of Science, Cochrane Library, CINAHL and PsycINFO from inception to 12 June 2023 was performed. Risk of bias was assessed using the Revised Cochrane risk-of-bias tool for randomised trials (RoB 2). Meta-analyses were conducted using Review Manager 5.4 and narrative syntheses were adopted whenever meta-analysis was inappropriate. The overall certainty of the evidence was rated using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: Of 15,351 records identified, nine were eligible and data were available for seven randomised controlled trials, three of which were identified as having a high risk of bias, one as low risk, and five as having some concerns. Subgroup pooled analyses indicated that multicomponent exercise engaged in longer exercise sessions (>60 min) was effective in improving quality of life immediately post-intervention and through 3-6 months post-intervention. However, multicomponent exercise did not significantly affect depression and anxiety. CONCLUSIONS: Multicomponent exercise with longer duration of exercise sessions has promising effects on both short- to medium-term quality of life among stroke survivors. PATIENT OR PUBLIC CONTRIBUTION: This does not apply to our work as it is a review paper. RELEVANCE TO CLINICAL PRACTICE: Healthcare providers could consider encouraging the patients to participate in multicomponent exercise sessions for more than 60 min. It is important to note that stroke survivors should be supervised by trained personnel at the beginning of the training. REGISTRATION: The protocol was registered on PROSPERO.

Effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults: A meta-analysis of randomised controlled trials.

OBJECTIVES: This study aims to evaluate the effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults living in the community and provide the latest evidence from published randomised controlled trials (RCTs). BACKGROUND: The number of frail older adults is rapidly increasing. Previous studies have reported that multicomponent exercise is one of the best types of intervention for increasing muscle strength, muscle endurance and balance for frail older adults. However, due to the small sample size and lack of evidential support, a meta-analysis of RCTs remains necessary. METHODS: RCTs reporting the effects of multicomponent exercise on the muscle strength, muscle endurance and balance of frail older adults, published in English, were retrieved from five electronic databases: PubMed, CINAHL, Web of Science, Embase and Cochrane Library available from their inception up to January 2021. RevMan5.3 software was adopted for statistical analysis. This study followed the PRSIMA checklist. RESULTS: A total of 10 articles and 667 patients were included in this study. Meta-analysis showed that multicomponent exercise could improve the muscle strength [MD = 2.46, p = .007], muscle endurance [MD = 2.16, p = .03] and balance [MD = .39, p = .03] of frail older adults, and subgroup analysis showed the muscle endurance of frail older adults was significantly improved as the intervention lasted for >12 weeks. CONCLUSIONS: RCTs provided in this study show the latest evidence that multicomponent exercise can improve the muscle strength, endurance and balance of frail older adults and that long-duration (>12weeks) multicomponent exercise is more effective for improving muscle endurance. RELEVANCE TO CLINICAL PRACTICE: Multicomponent exercise contributes to improving the muscle strength, muscle endurance and balance of frail older adults, so it can be considered as a complement to the physical function management programme for frail older adults.

Efficacy of a multicomponent exercise training program intervention in community-dwelling older adults during the COVID-19 pandemic: A cluster randomized controlled trial.

The coronavirus disease 2019 (COVID-19) pandemic caused changes in lifestyle for older adults such as reduced physical activity and community participation. Community activity centers were randomly assigned to the intervention (n = 82) or control arm (n = 85). The intervention comprised one 60 min group exercise session per week in weeks 1-8 and an online home exercise program in weeks 9-16. Physical activity, physical performance, and prefrailty rates were assessed at baseline and 16 weeks. At 16 weeks, compared to the control arm, the intervention arm exhibited improved (p < 0.05) leisure-time physical activity (phi = 0.571), vigorous physical activity (phi = 0.534), and moderate-vigorous physical activity (phi = 0.344); prefrailty rates (phi = 0.179); and short physical performance battery results (η2p = 0.113). The intervention thus effectively improved physical activity levels, physical performance, and prefrailty rates in community-dwelling older adults during the COVID-19 pandemic.

Effect of a multicomponent programme based on reality orientation therapy on the physical performance and cognitive function of elderly community-dwellers: a quasi-experimental study.

BACKGROUND: Effects of a multicomponent exercise programme have an impact on the physical, cognitive, and psychological domains in elderly community-dwellers. However, some individuals aged 65 years or more have not shown positive effects after the intervention as reported in similar research. The objective of this quasi-experimental study was to clarify the effectiveness of a multicomponent programme based on reality orientation therapy (ROT) on the physical performance, cognitive ability, and psychological state in the elderly. METHOD: Participants were recruited from the general public in 20 areas of Akita Prefecture, Japan, and they took part in each exercise programme for 90 min a day, once every 2 weeks, for 3 months, according to the group classification using cluster randomization into 20 cohorts in Akita. Physical, cognitive, and geriatric depression assessments were performed at baseline and after the 3-month intervention in both the ROT-based intervention group and the control group. RESULT: The final samples for analysis consisted of 31 participants in the control group and 30 participants in the intervention group. The results of the statistical analysis comparing the two groups showed that the 5-repetition sit-to-stand test was performed significantly faster (P < 0.05) and that the results of the word list memory (WM) test and the Symbol Digit Substitution Task also had significantly improved (P < 0.05) after the intervention in both groups. The WM score did not show an interactive effect between the group and time factors, but it had a significant main effect on time in both groups (P < 0.05). CONCLUSION: The results of our quasi-experimental study indicated that the multicomponent programme based on the ROT would be as effective as the original multicomponent programme combined with aerobic exercise and cognitive tasks, as highlighted in the WM.

Associations of multicomponent exercise and aspects of physical performance with frailty trajectory in older adults.

BACKGROUND: Previous research has shown that frailty leads to falls, institutionalization, hospitalization, and the loss of functional capacity. While numerous intervention methods aim to reverse frailty, the most effective in older adults is multicomponent exercise. Physical performance has been highlighted as a key factor in mobility, independence, and the burden of chronic disease. Several studies have demonstrated an association between physical performance and frailty; however, the relation between the two over the long term has not yet been fully investigated. Therefore, the current study aims to examine how aspects of physical performance are associated with frailty in the long run for older adults in Taiwan. METHODS: This nine-month longitudinal study employed the generalized estimating equation (GEE) modeling to identify measures associated with frailty trajectory. A sample of 159 community-dwelling older adults was recruited through purposive sampling in 12 community care centers in Taiwan. A quasi-experimental approach was adopted in which participants were assigned to the control group or to receive a multicomponent exercise intervention and examined sociodemographic, physical performance, and other factors at the baseline, post intervention (3 months), and follow up (6 months) levels. The multicomponent exercise program was designed based on the principles of the American College of Sports Medicine and comprised aerobic exercise, muscle-strengthening activities, balance training, and stretching exercises once per week for 2 h per session for 12 weeks. RESULTS: After intervention, we found that the multicomponent exercise group exhibited better performance in the 2-minute step test than the control group (p < 0.05). Regarding long-term effects on frailty trajectories, the study finds that age progression, being female, and longer completion time in the timed up and go test increase the probability of frailty (p < 0.05). Conversely, more steps in the 2-minute step test and undertaking the multicomponent exercise program reduced the long-term probability of frailty (p < 0.05). CONCLUSIONS: This study is the first to explore the relation between indicators of physical performance and frailty trajectory among older adults in Taiwan. Furthermore, we provided support for the efficacy of the multicomponent exercise program in improving frailty status.

Multicomponent exercise for physical fitness of community-dwelling elderly women.

[Purpose] The purpose of this study was to identify whether a 4-week multicomponent exercise program could improve the level of physical fitness of community-dwelling elderly women. [Subjects and Methods] Twenty-two healthy community-dwelling elderly women were randomly allocated to either an experimental or a control group. Experimental subjects performed a multicomponent exercise program that consisted of balance, strengthening, and stretching exercises for 4 weeks, whereas the control subjects did not perform any specific exercise. The subjects' level of physical fitness was assessed prior to and after training using the Senior Fitness Test which assesses muscle strength, flexibility, dynamic balance/agility, aerobic endurance, and body composition. [Results] Subjects in the experimental group showed significant improvements in lower and upper body strength, lower and upper body flexibility, dynamic balance/agility following training, but not in aerobic endurance or body composition. Significant group differences were shown in lower and upper body strength, lower body flexibility, and dynamic balance/agility. [Conclusion] The results suggest that a multicomponent training program that consists of balance, strengthening, and stretching exercises is a relevant intervention for the improvement of the level of physical fitness of community-dwelling elderly women.

Effect of multicomponent exercise intervention in community dwelling frail elderly: A systematic review and meta-analysis.

OBJECTIVE: To assess the impact of multicomponent exercises on physical functions of frail elderly in communities, evaluating their effect on muscle strength, balance, and endurance, and their influence on quality of life. METHOD: PubMed, Embase, Cochrane, and Web of Science were searched to collect relevant randomized controlled trials. The search cutoff date was January 24, 2024. Included studies met pre-specified inclusion and exclusion criteria. Data analysis was performed using Revman 5.4 and Stata 15.0 software. RESULT: This analysis included 19 studies. After 12 weeks, the multicomponent exercises significantly enhanced participants' performance in various physical function assessments. Specifically, in the Timed Up and Go Test, the exercise group showed a significant reduction in time [SMD = -0.86 (95 % CI: -1.40 to -0.33)]. In the Short Physical Performance Battery, interventions shorter than 6 weeks significantly increased scores [SMD = 1.01 (95 % CI: 0.64 to 1.37)], and those longer than 6 weeks showed improvements [SMD = 0.53 (95 % CI: 0.26 to 0.80)]. Muscle strength also improved, with handgrip strength and knee extensor strength enhancements [SMD = 0.93 (95 % CI: 0.27 to 1.59); SMD = 0.72 (95 % CI: 0.24 to 1.20)]. However, there was no statistically significant difference in walking speed between the groups [SMD = 0.04 (95 % CI: -0.33 to 0.40)]. CONCLUSION: Although multicomponent exercises significantly improve muscle strength, balance, and endurance in frail elderly individuals, there is no conclusive evidence of their effect on enhancing quality of life or long-term health outcomes. Further research is needed to explore the specific impacts of different types and intensities of exercises on this population.

Trends in Multicomponent Training Research in the Aged Population: A Bibliometric Analysis.

The proportion of aged populations is increasing worldwide. Exercise has a palliating effect on some adverse implications of aging. Multicomponent training (MCT) is a recommended form of exercise for the aged population. The aims of this research were to (1) study the number of publications regarding MCT in the aged population following an exponential growth rate; (2) identify the journals, authors, and countries that stand out the most in this area; and (3) describe the most common themes and used keywords in this field. The analysis was performed through the traditional laws of bibliometrics, including, Price's, Lotka's, Bradford's, and Zipf's law. All documents published in journals indexed in the Web of Science (WoS) Core Collection from 2001 to November 2023 that met the inclusion criteria were included. The 485 documents included in this review revealed that the number of annual publications experienced an exponential growth phase, 15 journals with six or more publications formed the core journals on this topic, and the author Mikel Izquierdo and his collaborative network topped the lists of prominent and prolific co-authors. Spain was the leading country in number of publications. Various thematic lines and keywords regarding strength, sarcopenia, quality of life, falls, balance, dual-task exercise, and cognitive and physical functioning were identified. In conclusion, this work confirmed that research on this topic is going through an exponential growth phase and provided detailed information about the journals, authors, and countries involved in the subject, as well as the keywords most frequently used in the subject matter.

A Prospective Observational Study of Frailty in Geriatric Revitalization Aimed at Community-Dwelling Elderly.

(1) Background: The increasing life expectancy brings an increase in geriatric syndromes, specifically frailty. The literature shows that exercise is a key to preventing, or even reversing, frailty in community-dwelling populations. The main objective is to demonstrate how an intervention based on multicomponent exercise produces an improvement in frailty and pre-frailty in a community-dwelling population. (2) Methods: a prospective observational study of a multicomponent exercise program for geriatric revitalization with people aged over 65 holding Barthel Index scores equal to, or beyond, 90. The program was developed over 30 weeks, three times a week, in sessions lasting 45-50 min each. Frailty levels were registered by the Short Physical Performance Battery, FRAIL Questionnaire Screening Tool, and Timed "Up & Go" at the beginning of the program, 30 weeks later (at the end of the program), and following 13 weeks without training; (3) Results: 360 participants completed the program; a greater risk of frailty was found before the program started among older women living in urban areas, with a more elevated fat percentage, more baseline pathologies, and wider baseline medication use. Furthermore, heterogeneous results were observed both in training periods and in periods without physical activity. However, they are consistent over time and show improvement after training. They show a good correlation between TUG and SPPB; (4) Conclusions: A thirty-week multicomponent exercise program improves frailty and pre-frailty status in a community-dwelling population with no functional decline. Nevertheless, a lack of homogeneity is evident among the various tools used for measuring frailty over training periods and inactivity periods.

Effects of multicomponent exercise on cognitive function in persons with mild cognitive impairment: A systematic review and meta-analysis.

BACKGROUND: Multicomponent exercise has the potential to improve cognitive function in people with mild cognitive impairment. However, the effects of multicomponent exercise on specific cognitive subdomains in mild cognitive impairment and the optimal combination of exercise components remain unclear. OBJECTIVE: This systematic review aimed to (a) investigate the effects of multicomponent exercise on different cognitive subdomains in people with mild cognitive impairment and (b) investigate the effects of different combinations of multicomponent exercise on global cognition in people with mild cognitive impairment. DESIGN: A systematic review and meta-analysis. METHODS: Six electronic databases, including PubMed, Medline, EMBASE, Web of Science, Cochrane Library, and CINAHL were systematically searched from inception to January 1st, 2023. Randomized controlled trials assessing the effect of multicomponent exercise interventions on cognitive function in people with mild cognitive impairment were included. The risk of bias was assessed using the Cochrane collaborative bias assessment tool. A random-effects model was used to calculate standardized mean difference. Subgroup analyses, meta-regression, and sensitive analysis were performed. If a meta-analysis was not feasible, studies were synthesized narratively. RESULTS: Twenty studies were identified for systematic review and meta-analysis. Multicomponent exercise significantly improved global cognition [SMD = 1.04; 95 % confidence interval (CI): 0.53, 1.55], cognitive flexibility (SMD = -1.04; 95 % CI: -1.81, -0.27), processing speed (SMD = 0.43; 95 % CI: 0.04, 0.82), verbal fluency (SMD = 0.38; 95 % CI: 0.13, 0.63), attention (SMD = -0.90; 95 % CI: -1.68, -0.12) and memory (SMD = 0.36; 95 % CI: 0.04, 0.69) in mild cognitive impairment. The multicomponent exercise including cardiovascular (exercise that promotes cardiovascular health, such as endurance training or aerobic exercise) and motor (exercises that improve physical abilities, such as balance, coordination, agility, flexibility, etc.) components positively affected global cognition in people with mild cognitive impairment (SMD = 1.06; 95 % CI: 0.55, 1.57). CONCLUSIONS: The findings of this study suggest that multicomponent exercise has a positive impact on various cognitive domains, including global cognition, cognitive flexibility, processing speed, verbal fluency, attention and memory in mild cognitive impairment. Specifically, the combination of exercises including cardiovascular and motor components was found to be effective in improving global cognition. However, further research is needed to investigate the optimal frequency and intensity of the multicomponent exercise intervention, and more detail about exercise combinations of the motor component (not classified in this study) for individuals with mild cognitive impairment. REGISTRATION: The protocol was registered on PROSPERO (CRD42023400302).

Multicomponent Exercise Intervention for Preventing Falls and Improving Physical Functioning in Older Nursing Home Residents: A Single-Blinded Pilot Randomised Controlled Trial.

Background: Older nursing home residents are at a greater risk of falling due to frailty. Exercise is effective at hampering frailty and related adverse events, including falls. Objectives: Our purpose was to evaluate the effect of a 12-week moderate-intensity multicomponent exercise programme on the number of falls and physical functioning among older nursing home residents. Also, we examined the association between the number of falls and demographics as well as physical and cognitive baseline data. Methods: The study protocol was registered on clinicaltrials.gov with the following identifier: NCT05835297. Older adults aged 65 years and over were recruited from a nursing home, and eligible and consenting residents were randomly allocated to two parallel groups: the intervention group, which performed a multicomponent exercise programme composed of strength, balance, and aerobic training (n = 12), and the control group, which received usual care (n = 12). Outcomes included falls, and measures of strength, balance, and mobility. Results: We had high adherence to exercise sessions, and no adverse events were recorded. We observed a non-significant reduction in falls (p = 0.34) and a significant improvement in Short Physical Performance Battery (p = 0.003) after the exercise programme. Falls were associated with being female and having diminished physical or cognitive function. Conclusions: Multicomponent exercise programmes should be implemented regularly in nursing homes for their effectiveness. Future studies with bigger samples, including participants with worse physical and cognitive impairments, as well as follow-up periods are required.

Effects of physical training on functional, clinical, morphological, behavioural and psychosocial outcomes in post-COVID-19 infection: COVID-19 and REhabilitation study (CORE-study)-a study protocol for a randomised controlled clinical trial.

BACKGROUND: The COVID-19 pandemic remains ongoing, with a significant number of survivors who have experienced moderate to severe clinical conditions and who have suffered losses of great magnitude, especially in functional capacity, triggering limitations to daily autonomy and quality of life. Among the possibilities of intervention for disease rehabilitation, physical exercise training stands out, which can benefit several health outcomes and favours the adoption of healthier behaviours. Therefore, the aim of the study will be to analyse the effects of physical training on the functional, clinical, morphological, behavioural and psychosocial status in adults and the elderly following COVID-19 infection. METHODS: A randomised controlled clinical trial is to be conducted in parallel, with the experimental group undergoing an intervention involving a multicomponent physical rehabilitation programme, carried out at the Sports Center in partnership with the Academic Hospital of the Federal University of Santa Catarina, in Florianópolis, Brazil. Participants will be adults and the elderly, of both sexes, in a post-COVID-19-infection state, who were hospitalised during the infection. The intervention will have a total duration of 24 weeks and will include a multicomponent physical training programme, which will have gradual progression in frequency, duration and intensity over time. Regarding the outcomes, before, at the 12th and after 24 weeks of intervention, functional (primary outcome = functional index of aerobic capacity), clinical, morphological, behavioural and psychosocial outcomes will be assessed. DISCUSSION: This study will contribute to a greater understanding of the safety, adherence and benefits of physical training in the rehabilitation of post-COVID-19 patients. The results of this study will be disseminated through presentations at congresses, workshops, peer-reviewed publications and local and international conferences, especially with a view to proposing a post-COVID-19 rehabilitation care protocol.

Tailored Prevention of Functional Decline through a Multicomponent Exercise Program in Hospitalized Oncogeriatric Patients: Study Protocol for a Randomized Clinical Trial.

BACKGROUND: Cancer mostly affects older adults, causing a wide variety of diagnostic and therapeutic dilemmas. One of the most important moments in cancer patients is the hospitalization period, in which older patients usually remain bedridden for many hours and this may lead to the appearance of sarcopenia and disability. METHODS: We present the research protocol for a randomized controlled trial that will analyze whether an intervention applied to older patients (≥ 65 years) who are hospitalized for acute medical conditions in an Oncology Department improves function. A total of 240 hospitalized older patients will be recruited in the Hospital Universitario de Navarra, Pamplona, Spain, and they will be randomized. The intervention consists of a multicomponent exercise training program that will take place for 4 consecutive days (2 sessions/day). The control group will receive usual hospital care, which will include physical rehabilitation when needed. The primary end point will be the change in functional capacity from baseline to hospital discharge, assessed with the Short Physical Performance Battery (SPPB). Secondary end points will be changes in cognitive and mood status, quality of life, fatigue, strength (dynamic and handgrip), pain, nutrition, length of stay, falls, readmission rate and mortality at 3 months after discharge. RESULTS: Basal data of the patients included in the RCT are described. The foreseen recruitment will not be achieved due to the context of the Covid pandemic and the significantly different responses observed during the clinical trial in oncogeriatric patients compared to our previous experience in older adults hospitalized for medical reasons. DISCUSSION: If our hypothesis is correct and shows that a multicomponent, individualized and progressive exercise program is an effective therapy for improving the capacity of acutely hospitalized older patients compared to usual care, a change in the current system of hospitalization may be justified in oncogeriatric patients.

Effects of short-term multicomponent exercise intervention on muscle power in hospitalized older patients: A secondary analysis of a randomized clinical trial.

BACKGROUND: Bed rest during hospitalization can negatively impact functional independence and clinical status of older individuals. Strategies focused on maintaining and improving muscle function may help reverse these losses. This study investigated the effects of a short-term multicomponent exercise intervention on maximal strength and muscle power in hospitalized older patients. METHODS: This secondary analysis of a randomized clinical trial was conducted in an acute care unit in a tertiary public hospital. Ninety (39 women) older patients (mean age 87.7 ± 4.8 years) undergoing acute-care hospitalization [median (IQR) duration 8 (1.75) and 8 (3) days for intervention and control groups, respectively]) were randomly assigned to an exercise intervention group (n = 44) or a control group (n = 46). The control group received standard care hospital including physical rehabilitation as needed. The multicomponent exercise intervention was performed for 3 consecutive days during the hospitalization, consisting of individualized power training, balance, and walking exercises. Outcomes assessed at baseline and discharge were maximal strength through 1 repetition maximum test (1RM) in the leg press and bench press exercises, and muscle power output at different loads (≤30% of 1RM and between 45% and 55% of 1RM) in the leg press exercise. Mean peak power during 10 repetitions was assessed at loads between 45% and 55% of 1RM. RESULTS: At discharge, intervention group increased 19.2 kg (Mean Δ% = 40.4%) in leg press 1RM [95% confidence interval (CI): 12.1, 26.2 kg; P < 0.001] and 2.9 kg (Mean Δ% = 19.7%) in bench press 1RM (95% CI: 0.6, 5.2 kg; P < 0.001). The intervention group also increased peak power by 18.8 W (Mean Δ% = 69.2%) (95% CI: 8.4, 29.1 W; P < 0.001) and mean propulsive power by 9.3 (Mean Δ% = 26.8%) W (95% CI: 2.5, 16.1 W; P = 0.002) at loads ≤30% of 1RM. The intervention group also increased peak power by 39.1 W (Mean Δ% = 60.0%) (95% CI: 19.2, 59.0 W; P < 0.001) and mean propulsive power by 22.9 W (Mean Δ% = 64.1%) (95% CI: 11.7, 34.1 W; P < 0.001) at loads between 45% and 55% of 1RM. Mean peak power during the 10 repetitions improved by 20.8 W (Mean Δ% = 36.4%) (95% CI: 3.0, 38.6 W; P = 0.011). No significant changes were observed in the control group for any endpoint. CONCLUSIONS: An individualized multicomponent exercise program including progressive power training performed over 3 days markedly improved muscle strength and power in acutely hospitalized older patients.

Agility training to integratively promote neuromuscular, cardiorespiratory and cognitive function in healthy older adults: a one-year randomized-controlled trial.

BACKGROUND: Exercise training recommendations for seniors include the targeted training of strength, balance, endurance and flexibility domains. Agility training (AT) is conceptualized as a multi-component and time-efficient training framework for older adults to improve physical, functional and cognitive health domains that are relevant for maintaining activities of daily living. The aim of this one-year trial was to comparatively evaluate the effects of agility training on physical and cognitive function. METHODS: Seventy-nine healthy older adults (AT: 61.5% female, 70.8 ± 4.8 years, 27.7 ± 4.2 kg/m2; CG: 60.5% female, 69.6 ± 4.7 years, 27.5 ± 4.4 kg/m2) took part in this one-year randomized controlled intervention and were either assigned to the agility training group (AT) with two weekly 60 min AT sessions or to the control group (CG), receiving no treatment. Participants were assessed pre, intermediate and post intervention for strength and power, balance, gait speed under multi-task conditions, aerobic capacity as well as cognitive performance. Linear mixed effects models were used to analyze the effect of treatment over time. RESULTS: Fifty-four participants (AG: 25, CG: 29) were analyzed, most drop-outs attributed to COVID-19 (17/30 dropouts). Adherence was good (75%) of 90 offered sessions. Notable effects in favor of AT were found for gait parameters in single (d = 0.355, Δ = 4.3%), dual (d = 0.375, Δ = 6.1%) and triple (d = 0.376, Δ = 6.4%) task conditions, counter movement jump performance (strength and power) (d = 0.203, Δ = 6.9%), static one leg balance (d = 0.256, Δ = 12.33%) and n-back reaction time (cognitive performance) (d = 0.204, Δ = 3.8%). No effects were found for the remaining outcomes (d < 0.175). CONCLUSION: AT might serve as an integrative training approach for older adults particularly improving gait and lower limb power parameters. It seems suitable to improve a broad range of seniors' health domains and should replace isolated training of these domains. However, individual variation and progression of exercises should be considered when programming agility training providing adequate challenges throughout a long-term intervention for all participants.

Gamified family-based health exercise intervention to improve adherence to 24-h movement behaviors recommendations in children: "3, 2, 1 Move on Study".

BACKGROUND: Evidence suggests that movement patterns, including physical activity, sedentary behavior, and sleep duration, throughout a 24-h period, have a significant impact on biological processes and health outcomes for both young and adult populations. However, 80% of adolescents worldwide are not sufficiently active, and many children do not meet international physical activity recommendations for their age. Thus, the aim of this study is to evaluate the impact of a 12-week gamified family-based health and exercise intervention on physical fitness, basic motor competencies, mental and behavioral health, and adherence to 24-h movement guidelines in children aged 4 to 5 years old. The study will evaluate changes in sedentary levels, physical fitness, basic motor competencies, mental and behavioral disorders, adherence to the exercise program, and compliance with physical activity recommendations. In addition, the aim of this protocol is to describe the scientific rationale in detail and to provide information about the study procedures. METHODS/DESIGN: A total of 80 children, aged 4 to 5 years old, will be randomly assigned in a 1:1 ratio to one of two groups: the exercise group and the routine care group. The exercise group will undergo a 12-week exercise intervention, followed by a 12-week follow-up period. On the other hand, the routine care group will undergo a 12-week period of routine care, followed by a 12-week follow-up control period. The exercise program will be implemented in a family setting and facilitated through a gamified web platform with online supervision, with the hypothesis that it will have a positive impact on physical fitness, anthropometric measures, basic motor competencies, and adherence to 24-h movement guidelines. DISCUSSION: The results of this study will provide valuable insights into the impact of a gamified, family-oriented health and exercise program on various aspects of health, including physical fitness, basic motor competencies, mental and behavioral well-being, and adherence to 24-h movement guidelines. The findings will contribute to closing the gap in current knowledge on the effectiveness of these types of interventions for children and their parents. These findings will also contribute to  the development of future guidelines for promoting physical activity in children who do not meet the World Health Organization's recommended levels. An online "3, 2, 1 Move on Study" is believed to increase accessibility, promoting health equity, and reducing economic barriers for all children and their families across diverse social groups.

Impact of Exercise Interventions on Sustained Brain Health Outcomes in Frail Older Individuals: A Comprehensive Review of Systematic Reviews.

Several systematic review studies highlight exercise's positive impact on brain health outcomes for frail individuals. This study adopts a Comprehensive Review of reviews (CRs) approach to amalgamate data from existing reviews, focusing on exercise's influence on brain health outcomes in older frail and pre-frail adults. The methodology involves a thorough search of Portuguese, Spanish, and English-indexed databases (i.e., Ebsco Health, Scielo, ERIC, LILACS, Medline, Web of Science, SportDiscus) from 1990 to 2022, with the AMSTAR-2 tool assessing evidence robustness. The search terms "physical exercise", "elderly frail", and "systematic review" were employed. Results: Out of 12 systematically reviewed studies, four presented high-quality (with metanalyses), while eight exhibit critically low quality. Positive trends emerge in specific cognitive and neuromotor aspects, yet challenges persist in psychosocial domains, complex cognitive tasks, and ADL outcomes. This study yields reasonable and promising evidence regarding exercise's influence on quality of life and depression in frail older individuals. However, the impact on biochemical markers remains inconclusive, emphasizing the need for standardized methodologies. Conclusions: The findings highlight the importance of acknowledging methodological nuances for clinicians and policymakers when translating these results into impactful interventions for aging populations. This emphasizes the necessity for a comprehensive and customized approach to exercise interventions aimed at fostering the sustainability of overall well-being in older individuals, aligning with United Nations Sustainable Development Goal 3.

Resistance training and clinical status in patients with postdischarge symptoms after COVID-19: protocol for a randomized controlled crossover trial "The EXER-COVID Crossover Study".

BACKGROUND: Physical exercise induces a coordinated response of multiple organ systems, including the immune system. In fact, it has been proposed that physical exercise may modulate the immune system. However, the potential effect of an exercise program on COVID-19 survivors has not been investigated. Thus, the aim of this study is to evaluate the modifications in immunological parameters, physical condition, inflammatory profile, and perceived persistent symptoms after 6 weeks of supervised resistance training (RT), in addition to the standard care on the clinical status of patients with persistent COVID-19 symptoms. The objective of this protocol is to describe the scientific rationale in detail and to provide information about the study procedures. METHODS/DESIGN: A total of 100 patients with postdischarge symptoms after COVID-19 will be randomly allocated into either a group receiving standard care (control group) or a group performing a multicomponent exercise program two times a week over a period of 6 weeks. The main hypothesis is that a 6-week multicomponent exercise program (EXER-COVID Crossover Study) will improve the immunological and inflammatory profile, physical condition, and persistent perceived symptoms (fatigue/tiredness, musculoskeletal pain, and shortness of breath) in patients with postdischarge symptoms after COVID-19. DISCUSSION: Our results will provide insights into the effects of a multicomponent exercise program on immunological parameters, physical condition, inflammatory profile, and persistent perceived symptoms in patients with postdischarge symptoms after COVID-19. Information obtained by this study will inform future guidelines on the exercise training rehabilitation of patients with postdischarge symptoms after COVID-19.
