Physical Activity

This is a pilot RCT examining physical activity outcomes at 3 months across 3 conditions: use of large language model (LLM) fully self-directed; use of LLM with guidance; and use of online tools to help with sleep.

The purpose of this research is to investigate the feasibility, acceptability, appropriateness, and preliminary efficacy of a wearable and artificial intelligence-driven mobile application-based exercise prescription grounded in self-determination theory (SDT) and behavioral change techniques (BCTs) among older adults. As no data exists on the feasibility of AI-driven exercise programs grounded in SDT and multiple BCTs specifically for older adults, this will be a pioneering study to explore the feasibility of wearable and AI-driven exercise program protocols and the rates of acceptance and appropriateness of the exercise prescription intervention among older adults. In addition, this study will test the preliminary efficacy of the intervention on physical activity (PA), mental health, and quality of life. This study follows the National Institute of Health (NIH) stage model, and it represents stage 1b of the NIH stage model, which emphasizes the feasibility and actionable processes for delivering a new health intervention. Specifically, this study will: 1.Evaluate the research protocol feasibility of a wearable and AI-driven mobile application-based exercise prescription grounded in SDT and BCTs (of goal setting, self-monitoring, graded task, and demonstration) on older adults over 8 weeks 2. Evaluate the acceptability and appropriateness of a wearable, AI-driven, mobile application-based exercise prescription grounded in SDT and BCTs among older adults over 8 weeks. 3. Evaluate the preliminary impact of a wearable and AI-driven mobile application-based exercise prescription grounded in SDT and BCTs on older adult PA (steps per day and daily duration of light PA and Moderate-vigorous PA), sedentary time, sleep, mental health (depression and anxiety), and quality of life.

Heart diseases and other non-communicable diseases are serious health issues in countries like Pakistan. Many people who work in offices, like bank employees, sit for more than 8 hours a day. This is called a sedentary lifestyle, and it increases the risk of heart diseases. This research project aims to find out if a newly developed context specific mobile phone application can help these sedentary employees to improve their lifestyle. The app, called m-LIfE (mHealth-based Lifestyle Intervention for Employees), will be designed to help employees to move more during the day and eat healthier food like fruits and vegetables. The study will involve bank employees in urban Karachi, Pakistan. They will be divided into two arms: Intervention arm: Participants in this arm will use the m-LIfE app for 12 weeks. They will get reminders and tips to take breaks, exercise, and eat healthy. Routine care arm: Participants in this arm will receive printed basic educational material about prevention of risk factors of heart diseases and improving lifestyle. After the 12 weeks of intervention, there will be a follow-up period at 4th week to check if participants are maintaining healthy habits. This study could help find simple and affordable ways to improve the health of office workers and reduce pressure on the healthcare system.

This study aims to evaluate the effectiveness of NeoMayor, a mobile health (mHealth) intervention designed to improve cardiovascular health among older adults at elevated cardiovascular risk in Chile. NeoMayor is a smartphone-based application that provides personalized guidance on physical activity, diet, sleep, and mental well-being through a multidomain lifestyle approach. This multicenter randomized controlled trial will enroll community-dwelling older adults aged 55 to 75 years recruited from primary healthcare centers in urban and rural settings. Participants will be randomized in a 2:1 ratio to either the NeoMayor intervention or a control group receiving standard health information and usual care. The intervention duration will be four months. The primary objective is to determine whether the NeoMayor intervention improves cardiovascular health as measured by the Life's Essential 8 Cardiovascular Health Index. Secondary objectives include evaluating changes in cognitive performance, depressive symptoms, anxiety symptoms, quality of life and physical performance outcomes. The study will also assess feasibility and adherence to digital intervention.

This will be a proof-of-concept randomised control trial (RCT) study, where 100 pregnant women will be recruited in the first trimester of pregnancy and followed-up until delivery. It aims to test these following hypotheses: 1. pregnancy is a window of opportunity to implement good lifestyle habits of physical activity and exercise as pregnant women are in regular contact with health professionals and are likely motivated and be more confident to carry out these activities according to the guidelines 2. this integrated programme will effective in a healthcare setting, and will bring Singapore's "Guidelines on Physical Activity and Exercise in Pregnancy" guidelines to implementation 3. with enhanced self-efficacy and motivation, the proportion of women engaging in adequate physical activity during pregnancy will increase to meet recommended guidelines.

Postpartum women frequently experience impairments in sexual function, pelvic floor dysfunction, fatigue, and depressive symptoms, all of which may adversely affect their quality of life during the postpartum period. Although pelvic floor muscle training is recommended as part of postpartum rehabilitation, evidence regarding comprehensive physiotherapist-led exercise programmes specifically targeting postpartum sexual health remains limited. Furthermore, no standardized telerehabilitation programme has yet been evaluated using a randomized controlled trial design. The aim of this randomized controlled trial is to evaluate the effectiveness of the POSH-Ex (Postpartum Sexual Health Exercise) programme, a standardized 12-week physiotherapist-led telerehabilitation intervention designed to improve female sexual function and overall postpartum health after childbirth. Secondary objectives are to evaluate its effects on pelvic floor muscle strength, physical activity, fatigue, depressive symptoms, health-related quality of life, and body composition. A total of 84 postpartum women will be randomly allocated in a 1:1 ratio to either the intervention group or the control group. Participants in the intervention group will complete supervised online exercise sessions twice weekly for 12 weeks, while participants in the control group will receive usual postpartum care. Outcome assessments will be performed at baseline and immediately after completion of the intervention. The primary outcome is female sexual function assessed using the Female Sexual Function Index (FSFI). Secondary outcomes include pelvic floor muscle strength, physical activity, fatigue, depressive symptoms, health-related quality of life, and body composition. The findings are expected to provide high-quality evidence regarding the effectiveness of a standardized telerehabilitation programme for postpartum rehabilitation and may contribute to the development of evidence-based postpartum rehabilitation programmes and future clinical practice guidelines.

The goal of this clinical trial is to learn if a digitalised Exercise Fit Tool (EFT) mobile application can promote physical activity in adolescents aged 12-18 years who have completed treatment for hematologic cancer (e.g., leukaemia and lymphoma). The main questions it aims to answer are: 1. Is it feasible to conduct a larger randomised controlled trial of the digitalised EFT intervention? 2. Does the digitalised EFT intervention improve physical activity levels, physical activity self-efficacy, and quality of life at 6 months? Researchers will compare the digitalised EFT intervention group to a usual care group to see if the mobile application can promote physical activity levels, physical activity self-efficacy, and quality of life in adolescents with hematologic cancer.Participants will: 1. Receive a 20-minute educational session on how to use the mobile application 2. Use the mobile application to self-assess their appropriate physical activity level and exercise with a virtual coach 3. Complete questionnaires and wear an accelerometer at 1, 3, and 6 months after enrollment 4. Attend a 20-30-minute individual interview at 6 months (intervention group only, 10 participants)

The overarching aim is to improve cardiometabolic health and promote healthy ageing by supporting adults to adopt favourable lifestyle patterns identified through our observational research. The trial will recruit n=600 to be involved in Phase I (referred to as the "Optimisation Phase") of a two-phase project (Phase II trial registration will be submitted separately). All participants will complete a baseline study visit where, after consent taking, will complete a baseline questionnaire, receive a smartwatch each and additional wearables if applicable, and download the study app for the receiving and testing of interventions and completion of short form surveys. Participants will be involved in the continual evaluation and optimisation of ecological momentary interventions (EMIs) in adaptive, factorial, micro-randomised trials over 12 months. Consenting participants may also be contacted to participate in interviews to be involved in the co-design of interventions, or to provide insights to the feasibility and process evaluation of the trial.

The purpose of this study is to test a culturally tailored, smartphone-delivered intervention designed to increase physical activity and reduce risk for heart disease and type 2 diabetes among African American women.

Engaging in regular physical activity during midlife is a key lifestyle behavior associated with reduced risk for Alzheimer's disease and related dementias (AD/ADRD). Yet nearly half of midlife adults (48%) do not meet national physical activity guidelines. The purpose of this mechanistic trial is to identify effective goal setting techniques to enhance psychosocial processes of self-regulation for the successful promotion of PA and adherence to national PA guidelines among midlife adults, with the long-term goal of reducing AD/ADRD risk

The purpose of this study is to characterize the relationships between changes in cognitive functioning across the day and patterns of physical activity in older adults. Those who participate in the program will complete tests of cognition and several surveys at the start. They will then wear an activity monitor and complete four cognitive tests plus surveys per day for one week. After this week concludes, they will continue completing the surveys and cognitive tests, and will engage in one week of structured exercise at a research center and one week where they work to move throughout the day.

Choose to Move (CTM) is a 3-month, choice-based health-promoting program for low active older adults being scaled-up across British Columbia (BC), Canada. Recently, the investigators adapted CTM for the \>14000 people in BC who are on surgical waitlists for total knee replacement or total hip replacement (TKR/THR) for osteoarthritis (OA). The primary goals of this observational study are to describe how the adapted program, Choose to Move Replacement Ready (CTM-RR), is implemented in BC and determine if the adapted program improves health outcomes in people with hip and/or knee osteoarthritis who are on surgical waitlists for TKR/THR. The investigators will also evaluate whether any health benefits achieved by CTM-RR participants are maintained three months after they finish the program and also during the remaining time that they wait for their TKR/THR surgery. The investigators will work with referral partners from hospitals and orthopaedic clinics in BC to recruit participants into CTM-RR. Participants who enrol in CTM-RR will answer online survey questions about the program and about their physical activity, mobility, pain, function, quality of life, willingness to undergo surgery, overall perception of their joint condition, psychosocial health, self-efficacy, social isolation, loneliness, and sedentary time. CTM-RR activity coaches will also answer online survey questions about the program. CTM-RR participants, activity coaches, and referral partners will also participate in interviews about the program.

This clinical trial aims to evaluate whether a culturally adapted Snacktivity™ program can improve cognitive function and self-care abilities in patients with Chronic Obstructive Pulmonary Disease (COPD) in Hong Kong. The main questions it aims to answer are: 1. Does the Snacktivity™ program improve the cognitive function of participants (including both global cognition and targeted subdomains)? 2. Does the program improve participants' self-care abilities? The study consists of three sequential phases: Phase 1 (Co-design workshops): Co-design workshops will be conducted with COPD patients, healthcare professionals (nurses, physical therapists, occupational therapists), and family caregivers to culturally adapt the Snacktivity™ program for Hong Kong COPD patients. Phase 2 (Feasibility Pilot RCT): The adapted program will be tested in a small-scale pilot study to assess its feasibility and short-term clinical effects. Phase 3 (Full-scale RCT): A full-scale randomised controlled trial will be conducted to evaluate the program's efficacy on the primary and secondary outcomes. Participants in the intervention group will be asked to: Participate in the culturally adapted Snacktivity™ program that integrates short, manageable "snacks" of physical activity into daily routines. Wear an activity tracker to monitor physical activity levels. Complete questionnaires at multiple time points assessing cognitive function, self-care abilities, physical activity levels, self-efficacy, exercise capacity, quality of life, anxiety, and depression. Researchers will compare the intervention group to an attention control group (receiving usual care with health education) to see if the Snacktivity™ program leads to greater improvements in these outcomes.

Healthy School Recognized Campus is a Texas A\&M AgriLife Extension initiative that supports the delivery of school-based physical activity and nutrition programs for diverse youth across Texas. The purpose of this study is to conduct a type 2 hybrid implementation-effectiveness, cluster dual randomized controlled trial (DRCT) to assess both Healthy School Recognized Campus (HSRC) and the mentoring program.

The investigators aim to conduct a randomized controlled trial to compare two symptom-management programs for Black older adults with early cognitive decline (self-reported confirmed by testing) and chronic pain. The programs are Mindfulness-Based Cognitive Therapy with Walking (MBCT+w) and Active Living Every Day (ALED). The investigators will assess how each program may help in improving physical, cognitive, and emotional function. The investigators will also assess whether improvements in outcomes from the two programs are maintained through a 6-month follow-up.

This study aims to investigate the association between dietary intake, physical activity, sleep quality, and body composition in women in Kazakhstan. The study will recruit approximately 200 women aged 20 years and older undergoing routine DEXA examinations in Astana. Participants will complete validated questionnaires assessing diet, physical activity, sleep quality, and sarcopenia risk, alongside functional assessments. DEXA scans will provide measurements of fat mass, lean mass, visceral adipose tissue, bone mineral density, and appendicular skeletal muscle mass. The primary objective is to evaluate associations between dietary quality and DEXA-derived outcomes. Secondary objectives include assessing sarcopenia prevalence and examining relationships between physical activity, sleep quality, supplement use, and body composition. An optional second stage will explore associations between body composition and existing inflammatory and metabolic biomarkers from medical records. The findings are expected to provide the first comprehensive DEXA-based dataset on women's body composition and lifestyle factors in Kazakhstan and inform public health strategies.

Insulin resistance is an early etiological factor in the development of type-2 diabetes (T2D), which constitutes a large societal health burden with an expected additional rise in the years to come. Skeletal muscle is the body's largest lean tissue mass and the major site of glucose disposal in response to insulin stimulation. Prior studies have suggested that a fast skeletal muscle phenotype, including a predominant fast muscle fiber composition, reduced capillary density, low fat oxidation and muscle oxidative capacity may be implicated in insulin resistance and TD2 development. However, key questions pertain in relation to the cause and effect of these relationships as well as the interaction with potential confounders and effect-modifiers including life-style factors (e.g. diet and physical activity levels) and general participant characteristics (e.g. body composition and training status). In the present project, we therefore aim to derive muscle fiber type and extensively map the proteomic signature of the early stages of insulin resistance in a large cross-sectional study using a young and apparently healthy cohort prior to T2D development, including a thorough participant characterization. We will recruit \~250 participants (men and women) in the age of 20-30 years and conduct extensive phenotyping and tissue sampling across one laboratory-based test day and a scan visit, as well as measurements of physical activity level and glucose handling in free-living conditions with wearable sensors. The study has a longitudinal aspect as participants will be re-invited at 5-year intervals for up to 20 years to delineate the trajectory of metabolic health in relation to muscle phenotype measures. The results of the project are expected to lead to significant advancements in our understanding of the importance of muscle phenotype for early-stage insulin resistance and metabolic health trajectories. Such understanding has potentially important clinical implications, as it can open new avenues for targeted interventions and individualized early preventive strategies to counter or delay the progression of insulin resistance and associated metabolic and cardiovascular disorders.

This cross-sectional comparative study aims to evaluate the effects of sustainable exercise habits on cognitive awareness, body awareness, and sleep quality in university students. The main hypotheses are: H0: There is no difference in cognitive awareness, body awareness, and sleep quality between university students with sustainable exercise habits and those with a sedentary lifestyle. H1: There is a difference in cognitive awareness, body awareness, and sleep quality between university students with sustainable exercise habits and those with a sedentary lifestyle.

It is widely established that a lack of adapted physical activity (APA) and sedentary behaviors increase the prevalence of frailty, which exacerbates chronic diseases. Hospital stays amplify this phenomenon, leading to physical deconditioning, often irreparable, especially in older patients if it is not detected and treated promptly. To date, there is no standard of care focused on APA to address frailty acquired during hospital stays. In this context, the SHAPE project (Hospital System for Physical Activity and Active Participation) aims to prevent dependency in older adults with chronic diseases by developing an innovative patient journey based on APA. The project seeks to reduce frailty acquired during hospital stays by establishing standards for APA prescription, based on early diagnosis and intervention. SHAPE ensures equal access to care through an accessible and user-friendly web platform, designed for older users and also including those in rural areas. It fosters the resilience of healthcare systems by integrating a preventive and multidisciplinary approach into hospital treatments and optimizes resources through a tiered care model that provides progressive and personalized care. Although hospital stays have been shown to trigger physical deconditioning, there is no adapted physical activity program initiated by the hospital and followed at home after hospital discharge from a severe exacerbation in patients with chronic respiratory diseases. The SHAPE Project offers a highly beneficial tool for patients with acute or exacerbated chronic respiratory disease requiring hospitalization, promoting better overall recovery after discharge. Furthermore, this project will foster healthy lifestyles and promote health from a sustainability and prevention perspective. Of particular interest is the opportunity to offer a lifestyle change program (physical activity and hygiene-dietary measures) focused on respiratory patients and adapted to their specific needs. Moreover, the project is considered innovative in implementing healthy clinical practices through telemedicine. In addition, it offers post-hospital discharge services that, to date, have not been considered in a generic way for respiratory patients except in selective subgroups (post-COVID, patients included in lung transplant program, etc.). In respiratory patients who have required high-risk admission due to decompensation, the implementation of the SHAPE program after hospital discharge as a support program that combines an adapted physical activity plan and general hygiene and dietary advice will improve the health indicators (frailty, sarcopenia, dyspnea, exercise tolerance, quality of life) of these patients.

Studies comparing aerobic exercise with virtual reality or video game technologies to traditional games and classical exercise have been conducted in healthy adolescents, but no studies comparing virtual reality and video game technologies have been found. Based on all this, we aimed to investigate the effect of virtual reality and video game-based exercise programs on physical fitness and attention levels in healthy adolescents. The study was planned as a quantitative experimental randomized controlled trial. Healthy individuals aged 10-18 years who meet the inclusion criteria will be evaluated during the dates of the study. Individuals will be divided into 3 groups: a classical physical activity group, a virtual reality group, and a video-based game group. Each program will be implemented for 20-30 minutes, three days a week for eight weeks. The Physical Activity Scale for Adolescents was used to evaluate the physical activity of the individuals, the Multidimensional Body-Self Relationship Scale was used to measure body image, and the Exercise Benefit/Barrier Scale was used to measure exercise perception. To measure attention, balance, and reaction time, the D2 Attention Test, Y-Balance Test, and Nelson's Hand Reaction Test will be administered, respectively. In the virtual reality and video-based game group, the games played by participants will be similar to the physical activities performed in the classic exercise group. One or more games incorporating these physical activities will be selected.

This study is a cross-sectional research designed to investigate symptom severity, posture, musculoskeletal pain, and physical activity levels in individuals with gastroesophageal reflux disease (GERD).

The overarching goal of our research is to develop personalized and accessible healthy aging lifestyle interventions aimed at promoting physical activity (PA) and improving health among community-dwelling older adults living alone with cognitive decline (LACD). To achieve this goal, the purpose of this project is to determine whether wearable and app-based mHealth intervention component(s) will contribute to increased PA and improved health outcomes in older adults LACD. Our specific aims are to: identify and evaluate mHealth intervention components that practically and significantly contribute to enhanced mechanistic outcomes (e.g., self-efficacy, outcome expectations) and increased PA (primary outcome) in older adults LACD over a 6-month period; determine the optimal combinations of intervention components for future efficacy testing; elucidate the mechanism of behavioral change (MoBC) and potential outcomes of these intervention components, namely, the mediating effects of MoBC variables (e.g., self-efficacy, outcome expectations) on the relationship between intervention components and change in PA. The first two aims are primary and fully-powered. The third aim is exploratory. The aims will support a refined, data-driven intervention design for a subsequent larger trial.

This study evaluates the effect of street signs inviting to use the conventional stairs instead of escalators at a subway station without and with active pop music.

The goal of this clinical trial is to learn if an enhanced, culturally, socially, and structurally tailored Diabetes Prevention Program (E-DPP) can improve weight loss and related diabetes risk factors in African American adults with prediabetes living in low-income, socially vulnerable communities. The main questions it aims to answer are: * Does the enhanced DPP (E-DPP) lead to greater percent weight loss at 6 and 12 months compared to the standard culturally tailored DPP (S-DPP)? * How do social determinants (e.g., food insecurity, stigma, access to resources) influence weight loss and engagement in lifestyle behaviors? Researchers will compare a standard culturally tailored DPP (S-DPP) to an enhanced DPP (E-DPP) to see if improving access to healthy food, physical activity, and community resources increases weight loss and improves diabetes-related outcomes. Participants will 1. Attend DPP sessions delivered in community settings (e.g., churches) 2. Receive lifestyle education focused on diet, physical activity, and weight loss 3. Engage in physical activity (including in-class exercise sessions \[E-DPP only\] and community-based options) 4. Receive support for healthy eating, including food deliveries (\[E-DPP only\]), food selection guidance, and referrals to food assistance programs 5. Receive information and support for accessing community resources for food and physical activity

Obstructive Sleep Apnea Syndrome (OSA) is a condition characterized by repeated pauses or reductions in breathing during sleep, which can negatively affect sleep quality, daytime functioning, and physical capacity. Although regular exercise is known to have beneficial effects in OSA, the effects of different exercise approaches on circadian rhythm and functional capacity have not been sufficiently investigated.The primary aim of this study is to compare the effects of exercise snacking and aerobic exercise on circadian rhythm and functional capacity in individuals with OSA, in comparison with a control group. The secondary aim is to evaluate the effects of these exercise interventions on peripheral muscle strength, fatigue level, body composition, quality of life, and physical activity level.Participants will be randomly assigned to three groups: an aerobic exercise group, an exercise snacking group, and a control group. While the exercise groups will follow their respective intervention programs, the control group will continue their routine treatment.This study aims to answer whether exercise snacking, which consists of short bouts of exercise distributed throughout the day, may be an alternative or complementary approach to traditional aerobic exercise in individuals with OSA. In addition, this study aims to be the first randomized controlled trial evaluating the effects of exercise snacking on circadian rhythm and functional capacity in individuals with OSA.
