Participants will: * Perform the "Xuong tan lac than" exercise for 12 weeks (5 days per week, once daily). * Be trained to perform the exercise correctly before starting the intervention. * Undergo assessments of joint range of motion and muscle endurance at baseline and after 2, 4, 8, and 12 weeks.

Vitamin D and Physical Activity on Bone Health

This research will examine the effectiveness of vitamin D or placebo (the placebo is a tablet that looks like Vitamin D study drug, but has no Vitamin D study drug in it), with and without physical activity (walking and progressive resistance exercise), in treating bone loss in women who have undergone treatment for breast cancer. The investigators would also like to find out if the physical activity program improves cardiovascular fitness, energy expenditure, muscular strength, muscle mass, and balance. One hundred five (105) subjects are expected to take part in this study. The investigators don't know if bone loss in breast cancer survivors should be treated differently than bone loss in other women.

Sustainability of the Effects of an Adapted Physical Activity Program on Physical Fitness and Psycho-behavioral Factors in Patients With Chronic Diseases

This study aims to determine the extent to which different approaches to adapted physical activity coaching influence physical fitness, psycho-behavioral, and anthropometric parameters in patients with stabilized chronic conditions who have been referred to a Sport-Health Center by their physician. The trial includes four parallel groups, distinguishing between two program durations (3 months or 6 months) and the use or non-use of a smartwatch as a tool for monitoring activity. All participants complete 24 sessions of adapted physical activity (APA), in accordance with the standard practices of the La Musse Sport-Health Center, where the study is entirely conducted. However, the distribution of sessions differs by group: two sessions per week over three months or one session per week over six months. Randomization is stratified by age, sex, and baseline fitness level. Assessments are conducted at the following five time points: enrollment (T0), end of the 3-month program (T1), end of the 6-month program (T2), followed by follow-up at 12 months (T3) and 18 months (T4), to observe the durability of the effects after the supervised phase. The primary outcome measure is improvement in physical fitness and anthropometric parameters, objectively measured using tests recognized for their reliability (TDM6, Sit-to-Stand 30s, Timed Up and Go, Sit and Reach, grip strength, BMI, waist circumference). The secondary outcomes focus on changes in motivation toward health-related physical activity (EMAPS), perceived self-efficacy to engage in physical activity (ECS), and self-reported physical activity (IPAQ-SF), which will be collected regularly throughout the program, more frequently than in standard care. A total of 280 patients will be enrolled to ensure sufficient statistical power, taking into account an anticipated loss-to-follow-up rate over 18 months. Data collection and processing will be pseudonymized and conducted on the secure network of La Musse Hospital.

Effects of Physical Activity Training on Physical Fitness and Quality of Life in Paramedic Students

Brief Title: Effects of an 8-week physical activity program in paramedic students (RCT) Official Title: EFFECTS OF PHYSICAL ACTIVITY TRAINING ON PHYSICAL FITNESS AND QUALITY OF LIFE IN PARAMEDIC STUDENTS This randomized controlled trial aims to examine the effects of regular physical activity training on physical fitness and quality of life in paramedic students. The study plans an eight-week physical activity program for paramedic students studying healthcare. The program will consist of exercises designed to improve physical endurance, muscle strength, flexibility, and overall physical performance. Main Hypothesis (H₁): Regular physical activity training will significantly improve the physical fitness level and quality of life of paramedic students. H₁a: Regular physical activity training increases the cardiovascular endurance of paramedic students. H₁b: Regular physical activity training significantly improves students' muscle strength and flexibility. H₁c: Students' body mass index (BMI) values are positively affected after regular physical activity training. H₁d: Students who participated in the physical activity program had significantly higher quality of life scores (SF-36 subscales) than the control group. This randomized controlled trial will test the effectiveness of an 8-week, 3-day-per-week physical activity program to assess physical fitness and quality of life in paramedic students. Participants will be randomly assigned to either the intervention (exercise program) or a standard-of-care/waiting control group. Primary outcomes include physical endurance (short form of the International Physical Activity Questionnaire (IPAQ)) and the SF-36 total score. Measurements will be taken at pre-intervention, after 8 weeks, and at 3-month follow-up. Study Type: Interventional. Allocation: Randomized. Intervention Model: Parallel Assignment. Masking: None Primary Outcome Measures: Change in physical endurance (distance, meters) with physical activity exercises - from baseline to week 8. Change in health-related quality of life by SF-36 total score - from baseline to week 8. Time Frame: Baseline, week 8, 3-month follow-up. The study suggests that regular physical activity-based training programs can improve both the professional resilience and quality of life of paramedic students. These findings are expected to contribute to the inclusion of physical activity-based modules in health education programs and positively impact the professional productivity of future paramedics.

Impact of Training Load on the Gut miCrobiome And Its Relation to exeRcise Performance, mUscle Phenotype, and markerS of Overreaching in Healthy Men

The goal of this study is to learn how different amounts of supervised indoor cycling training change gut health (gut bacteria, the substances gut bacteria make, and the gut barrier integrity), and how these changes relate to changes in fitness, muscle health, and signs of doing too much training (a state called 'overreaching'). The study includes healthy, recreationally active men aged 18 to 45 years. The primary questions, for which the study is powered (sufficient participants included), are: 1. Does moderate load training change blood and faecal levels of butyrate (a short-chain fatty acid made by gut bacteria) after eight weeks compared with a control group? 2. Compared to moderate load training, do higher training loads lead to different responses in blood and faecal levels of butyrate? Researchers will compare: * A control group that does not complete structured training; * A moderate-load training group that completes eight weeks of supervised cycling (4x/week); * A high-load training group that completes four weeks of moderate-load training followed by four weeks of higher training load (twice the number of training sessions). Participants will: * Be randomly assigned to one of the three groups; * Complete 8 weeks of supervised indoor cycling sessions if assigned to a training group; * Complete four study assessment periods (baseline, after week four, after week eight, and after a short taper (rest period); * Provide blood, stool, skeletal muscle, urine, saliva, and breath samples during the assessment periods; * Complete fitness and performance tests and questionnaires during the assessment periods.

Adaptation of Lung Transplant Recipients at Extreme Altitude

This prospective observational study investigates the effects of intermittent hypoxic conditioning and real high-altitude exposure in lung transplant recipients compared with healthy controls. The study includes an eight-week home-based preparatory phase during which participants use a normobaric hypoxic tent with reduced oxygen concentration. Prior to this phase, all participants receive standardized training on the safe use of the equipment. During the preparatory period, daily vital parameters, including heart rate, oxygen saturation, and heart rate variability, are recorded using a sports watch and a pulse oximeter. Symptoms, adverse events, and subjective well-being are documented daily in an electronic diary. All data are transmitted to the study team via encrypted electronic systems, allowing continuous remote monitoring. At the end of the preparatory phase, participants undergo a clinical evaluation to confirm fitness for the expedition phase. The expedition phase consists of a monitored ascent of Aconcagua (6,971 meters). Before departure, all participants are required to attend a comprehensive safety, protection, and first aid training conducted jointly by the study team and professional expedition providers. The expedition is planned and led by an experienced international expedition company in cooperation with a local provider specializing in high-altitude mountaineering. The expedition includes arrival in Mendoza, preparatory procedures such as equipment checks and permits, followed by a staged ascent to base camp. Subsequent days involve rest periods and acclimatization hikes with the establishment of progressively higher camps. A summit attempt is planned after sufficient acclimatization, followed by descent to high camp. A weather-dependent buffer period is included before the final descent to the valley and return to Mendoza, where the expedition concludes. Total study participation is expected to last approximately 15 weeks, including about eight weeks of home-based preparation and approximately three weeks at altitude. A final follow-up examination is conducted 2 to 4 weeks after completion of the expedition, marking the end of study participation.

Diaphragmatic Kinesio Taping With HIIT in Trained Individuals

This study examines whether adding diaphragmatic kinesio taping to high-intensity interval training (HIIT) improves physical performance in trained individuals. Participants will be randomly assigned to one of two groups. One group will perform an 8-week HIIT program on a cycle ergometer. The other group will follow the same HIIT program and will also receive diaphragmatic kinesio taping before each exercise session. The taping is applied to support breathing muscles and may help improve oxygen use during exercise. Before and after the training period, participants will undergo tests to measure aerobic capacity (VO₂max), anaerobic power (Wingate test), balance (Y-Balance test), lung function (spirometry), body composition, and heart rate responses. The results of this study will help determine whether diaphragmatic kinesio taping provides additional benefits when combined with HIIT training.

Open Space and Closed Years

The primary objective of this project is to examine the effects of a specific multicomponent physical activity program (MPAP), conducted in an outdoor setting, on the health and functional-motor status (HFMS) of women over the age of 60. Additionally, the study will investigate the influence of sociodemographic factors (SDF), physical literacy (PL), and health literacy (HL) on the baseline HFMS and the subsequent changes resulting from the KTP. Study Methodology The program participants will consist of older women (\>60 years; n=60) whose current HFMS allows for participation in the exercise protocol. They will be divided into two groups: Experimental Group: Will participate in the MPAP. Control Group: Will not participate in the MPAP. The exercise intervention (MPAP) will include a combination of aerobic activities, strength exercises, balance, and flexibility. It will be conducted two to three times per week across two three-month cycles, separated by a three-month break. Data Collection and Environment Assessments: Sociodemographic factors, physical literacy, and health literacy will be measured at the start of the study. A series of HFMS indicators will be recorded before and after each exercise cycle. Setting: The MPAP will be performed outdoors in a public park. Project Significance Beyond analyzing the direct effects of the exercise program and the correlations between the measured variables, this project will contribute to a deeper understanding of the importance of the natural environment in implementing goal-oriented physical activity for the elderly population.

IMMUNO-FIT Observational Study

This observational study will investigate how immunotherapy affects physical fitness, quality of life, and treatment tolerance in adults with solid cancers. Immunotherapy can cause a range of side effects that impact daily functioning and may lead to treatment delays or early discontinuation. Physical fitness may influence how well patients cope with treatment, yet little is known about how fitness changes during immunotherapy or whether baseline fitness is linked to outcomes. Participants will complete fitness testing using cardiopulmonary exercise testing (CPET) and quality-of-life questionnaires before starting immunotherapy and again 12 weeks later. Blood samples will also be taken, and long-term outcomes including survival, disease progression, and quality of life will be followed for up to 24 months. All cancer treatment will remain standard of care. A small number of participants will be invited to take part in an optional research biopsy at week 12 to explore how physical fitness relates to changes in the tumour's immune environment. The study will help researchers understand natural changes in fitness during immunotherapy, identify whether baseline fitness is associated with treatment tolerance or outcomes, and generate information needed to design future trials testing exercise-based interventions during immunotherapy.

The Effects of Neuromuscular Training on Knee Biomechanics During Jump-Landing Among College Basketball Players Post ACL Reconstruction and Rehabilitation

Basketball players often injure the anterior cruciate ligament (ACL), a key structure that stabilizes the knee. Even after surgery and standard rehabilitation, many athletes continue to have problems with knee stability, movement control, and performance during jumping and landing. These issues increase the risk of re-injury and can limit their ability to return to competition. Neuromuscular training (NMT) is a type of exercise program that focuses on improving balance, muscle coordination, and movement patterns. It uses activities such as jump-landing drills, balance tasks, agility exercises, and core training. Previous research shows that NMT can help athletes land more safely, reduce harmful knee movements, and improve sport performance. However, little is known about its long-term benefits in college basketball players who are more than one year post-ACL surgery. This study aims to evaluate whether a 12-week NMT program, added to standard basketball training, can improve knee biomechanics, stability, and performance in college basketball players with a history of ACL reconstruction. Thirty participants will be randomly assigned to either an NMT group or a control group. Both groups will complete basketball training, but only the NMT group will receive the additional neuromuscular exercises. Knee movement will be measured using 3D motion capture and force plates, and performance will be tested through vertical jumps and other sport-specific tasks. The main outcomes will include knee angles during landing, ground reaction forces, dynamic stability, and jump height. The expected outcome is that athletes who undergo NMT will demonstrate safer landing strategies, better knee control, and improved performance compared to those who only receive standard basketball training. These findings may help coaches and healthcare providers design safer, more effective rehabilitation programs for athletes after ACL surgery.

This prospective, multi-site, single-arm interventional study evaluates the 5-Line Principle of Balanced Progressive Intensity Training (BPIT) over 5 weeks in healthy adults aged 18-65 years. All participants receive supervised BPIT sessions (3-5 per week) progressing through five intensity lines defined by anatomical landmarks and ground reaction force: Ground-Based (Low) Knee-Level (Low-Moderate) Standing (Moderate) Head-Level (Moderate-High) Plyometric (High-Impact) The study aims to quantify improvements in functional movement efficiency, joint mobility, postural control, strength adaptation, and heart-rate variability while monitoring safety and individual overload indicators.

The Effect of a Training Programme in the Variation of Fitness Parameters, Physiological, Hematological and Biochemical Indicators of Soccer Players During the Preseason Period

The goal of this study is to investigate the effects of varying friendly match-play exposure during the late pre-season on physiological, biochemical, and performance adaptations in soccer players. It is hypothesized that (i) significant changes will occur across the pre-season in both the extended- and limited-play groups when analysed independently; (ii) distinct group-specific adaptations will emerge by the end of the preparatory period; and (iii) match-play exposure, when analysed across all participants, will be significantly correlated with physiological and performance outcomes at pre-season completion. Players from a randomly selected team will be assessed at three time points: pre-season start, mid-pre-season (MPS), and pre-competition phase (PC). Assessments will include anthropometry, physical performance, and markers of muscle damage, inflammation, hormonal status, and haematology. Based on the total match-play time of 8 friendly games during the late pre-season, players will be retrospectively categorised into extended-play (EP) and limited-play (LP) cohorts.time of 8 friendly games during the late pre-season, players will be retrospectively categorised into extended-play (EP) and limited-play (LP) cohorts.

DanceOn50+: Effects of a Dance Program on Physical and Psycho-emotional Health

Aging is associated with a decline in physical and cognitive function affecting autonomy and the ability to perform daily living activities. Interventions aiming the promotion of healthy aging and life-long learning are required to improve physical and cognitive health in a social context. Dance is a cultural and physical activity that can be well adapted for older adults. Dance might counteract physical and cognitive functional decline and promotes social and emotional interactions. Importantly, dance can be individually adjusted in terms of physical fitness and cultural background. However, to date, there is a lack of research on the effects of a dance intervention with older adults setting to promote healthy aging and lifelong learning. Thus, this research project aims to explore the impact of a dance-based intervention with older adults from the community on physical, cognitive and psycho-emotional health while simultaneously generating inclusive artistic experiences and lifelong learning opportunities. The study includes a quantitative quasi-experimental design. The study sample consists of healthy individuals from the community aged ≥ 50 years recruited through community programs and social media platforms. Those who agree to participate will be informed of the project objectives and procedures. Participation in the study is voluntary, and all participants will be required to sign a voluntary informed consent form. Participants will be assigned to a dance training group, Multicomponent Exercise Group or the control group (no intervention). Outcomes will be measured using the Astrand Cycle Ergometer Submaximal Test, Open Circuit Pirometer Technique, Battery Senior Fitness Test, Isokinetic Dynamometer and Handgrip Dynamometer to assess physical fitness, Accelerometer, and Pittsburgh Sleep Quality Index to assess physical activity, sedentary behaviour, and sleep; psychoemotional questionnaires validated on Portuguese subjects to assess psychoemotional variables; tape measure and bioeletric impedance balance to assess body composition; digital sphygmomanometer and spirometry to assess cardiovascular and respiratory function; neurocognitive and psychological tests to assess cognitive function; and electroencephalography to assess electrophysiology.

Square Step Exercises in Healthy Young Adults

This study aims to compare the effectiveness of Square Stepping Exercise and aerobic exercise on cognitive function and physical fitness in young adults. Participants aged 18-30 with low physical activity levels will be randomly assigned to either the Square Stepping Exercise Group or Aerobic Exercise Group. Both interventions will be supervised by a physiotherapist, performed twice a week for 40 minutes over 4 weeks. Cognitive function will be assessed using various tests, including attention, short-term memory, and executive function evaluations. Physical fitness will be evaluated through jump tests and balance assessments. Blinded assessors will conduct evaluations at baseline and post-intervention in both groups to determine the impact of square stepping exercise and aerobic exercise on cognitive and physical health in young adults.

Influence of Strength Training on Myopia Care in Kindergarten Children

With the advancement of technology and changes in lifestyle, the physical activity levels of modern children have gradually decreased. This affects their physical health, psychological development, and social skills, and may increase the risk of nearsightedness. Therefore, it is essential to implement muscle training and outdoor activities in schools, travel agencies, and kindergartens. This project aims to promote the comprehensive development of children through systematic muscle training and enhanced outdoor activities, integrating college students from early childhood education programs, travel agencies, and kindergartens to establish habits that prevent nearsightedness. In the kindergarten setting, 60 children in the senior class will serve as the control group, while another 60 will be in the intervention group. The intervention group will participate in 10 weeks of muscle training and outdoor activities, including core exercises 3 times a week for 60 minutes each session from 4pm to 6pm. Additionally, there will be subsidized a total of 2 outdoor activities on weekends. This approach will not only improve the children's coordination and flexibility but also enhance their physical fitness. Regarding travel agencies, tailored outdoor activities specifically designed for young children can be created, such as ecological explorations and wilderness survival training, allowing children to enjoy the fun of movement and learning in a safe environment. Travel agencies should collaborate with educational institutions to provide professional guidance and safety assurances, giving parents peace of mind. For kindergartens, a comprehensive outdoor activity plan should be established, regularly organizing sports days and group competitions to encourage children to participate in team sports like soccer and relay races. This not only helps improve the children's muscle strength but also fosters their spirit of cooperation and social skills. Through these methods, we aim to effectively increase children's activity levels, promote their overall development, and reduce the risk of nearsightedness.

MOVI-OLE! [Open Learning Environments]

This study will evaluate the effectiveness of MOVI-OLE! (Open Learning Environment), a school-based intervention designed to reduce sedentary time and enhance multiple aspects of child development, including cognitive function, physical fitness, body composition, psychological well-being, and student engagement. The intervention combines dynamic classroom furniture with student-centered teaching practices. Additionally, a qualitative component will explore how students, teachers, and families perceive the feasibility and acceptability of implementing MOVI-OLE! in real-world school settings.

This 18-month study tracks how physical fitness relates to executive function in older adults, aiming to determine if fitness improvements predict better cognitive performance. Participants complete assessments at baseline and 18 months, including cardiorespiratory fitness (YMCA bike test), muscle strength (chest and leg press tests), and executive function (computer tasks with brain activity recording via EEG). Additional measures include physical activity questionnaires, cognitive screening (MMSE), memory tests (digit span), demographics (age, sex, education), and blood tests for APOE ε4 gene status. No exercise program will be provided, allowing observation of natural fitness-cognition relationships in daily life.

The Effects of Self-Myofascial Release on Physical Fitness and Swing Performance in Male Collegiate Golfers in China

This is a randomized controlled trial aimed at evaluating the effects of a self-myofascial release (SMR) program on physical fitness and swing performance in male collegiate golfers in China. The primary purpose is to determine whether SMR, using foam rollers and massage balls, can improve joint mobility, core control, balance, and golf-specific swing outcomes. The study seeks to answer the following key questions: Can an 8-week SMR program enhance physical functions such as mobility, balance, and trunk control in male collegiate golfers? Can SMR improve key performance indicators of golf swing, including club head speed, ball speed, carry distance, and accuracy? Participants (n=60) will be healthy male collegiate golfers aged 18-25, randomly assigned to either an experimental group (SMR) or a time-matched control group (no SMR). Both groups will undergo 8 weeks of golf training in a centralized camp with identical accommodations and practice schedules. The SMR group will perform supervised self-myofascial release exercises using Decathlon-brand foam rollers and balls, three times per week (30 min/session) in the gym after regular training. The control group will engage in supervised 30-minute sessions of passive golf-related video watching, scheduled at the same time and environment as the SMR sessions. Assessments will be conducted at Week 0 (baseline), Week 4 (midpoint), and Week 8 (post-intervention). Testing will include range-of-motion (ROM) measurements, balance tasks, strength/stability exercises, and golf swing performance using a TrackMan Launch Monitor. All outcome assessors will be blinded to group allocation to minimize bias. The study aims to provide evidence on whether SMR is an effective training strategy to enhance functional movement and sports-specific performance in amateur golfers.

Analysis of New Materials and Artificial Turf Products: Influence and Impact on Athlete Performance and Perception

This request pertains to a series of related projects on a common theme. Specifically, this set of projects aims to analyze the impact of new alternatives in materials and structures of artificial turf on athlete performance and perception, within the context of the elimination of microplastics as per Commission Regulation (EU) 2023/2055 of September 25, 2023. Third-generation sports artificial turf is notable for including performance infill (granules) that provide the necessary functionality and safety for sports practice. The vast majority of fields worldwide use materials that do not comply with the new European regulation, which has granted an eight-year moratorium. Therefore, there is little time to find new alternatives. The challenge lies not only in developing new structural solutions but also in understanding their impact on athletes. This issue is of high severity, as these sports facilities are the largest in terms of space and host the highest number of Physical Activity and Sports practitioners in Europe (mainly Football, Rugby, Hockey, and Padel). For this reason, over the past year, the IGOID Group has requested various projects to cover all the necessary phases and nuances to address this issue. The activities included in these projects are divided into two phases: Phase 1: Evaluation of Sports Surfaces in the Laboratory (durability and surface-player and surface-ball interaction). Tests will be conducted on artificial turf samples constructed with SBR rubber (the main material to be replaced under the EU regulation), natural-origin infills, polymeric infills larger than 5 mm, and other infills. Initially, a market analysis and classification will be carried out, followed by laboratory tests. Across all projects, a minimum of 30 alternatives are expected to be analyzed. Phase 2: Field Study. Tests will be conducted on a sample of athletes on constructed surfaces representing the different alternatives evaluated in Phase 1. Performance tests and a battery of assessments will be carried out to understand athlete perception. A sample of 30 athletes will be randomly divided into groups to perform different repetitions of the test batteries, covering a minimum of six different sports facilities.

Physical Exercise Prehabilitation Program in MEtabolic SuRgery

The goal of this clinical trial is to learn if an exercise program before bariatric surgery works to treat obesity, could improve physical condition and weight loss before bariatric surgery and induce a lifestyle behavior change. The main questions it aims to answer are: * Does a supervised exercise program lead to improved physical condition prior to bariatric surgery? * Does a supervised exercise program prior to bariatric surgery lead to reduced surgery related complications? * Does a supervised exercise program prior to bariatric surgery lead to maintained lifestyle changes after surgery? Participants will: * Receive either no training program or physical exercise training program twice a week, supervised by a physical therapist, for a duration of 8 weeks. * Have their fitness measured at the start and at the end of the 8 weeks, measured with a six minute walking test. * Fill in a survey on their perceived quality of life and exercise habits at the start of the trial, and at 1 year after surgery.
