Impact of a Mobile Exercise Application on Sleep, Pain, and Fitness in Healthy Adults

The aim of this study is to evaluate the effectiveness of a commercially available mobile exercise application on performance-related physical fitness outcomes and selected health indicators in healthy young adults. A total of 78 participants are randomly assigned to a conventional exercise group (n = 26), a mobile application-based exercise group (n = 26), or a control group (n = 26). Both intervention groups complete an identical six-week high-intensity interval training (HIIT) program, either supervised or delivered via the 7-Minute Workout® mobile application. The control group receives no intervention. Pre- and post-intervention assessments include muscular endurance (curl-ups, push-ups), lower extremity anaerobic power (vertical jump), and hamstring and lower back flexibility (sit-and-reach), as well as self-reported sleep quality (Pittsburgh Sleep Quality Index) and pain (Visual Analog Scale).

Swedish Physical Activity and Fitness Longitudinal Study

Aging means loss of strength, which can affect the ability to lead an active life and be independent. Physical activity can counteract the loss of strength to some extent, but individual differences are large and the mechanisms are partly unknown. The hypothesis is that changes in the innervation and composition of the muscle may explain the individual differences in strength loss. A group of Swedish men and women have participated in this study of physical performance for almost 50 years, since they were 16 years old. The project will improve the understanding of muscle aging. The findings may help to develop strategies to counteract muscle loss and enable healthy aging and to promote physical activity throughout life

Effects of Tiger Milk Mushroom Supplementation on Physical Performance in Physically Active Adults

This study aims to evaluate the effects of Tiger Milk Mushroom (TMM) supplementation on physical performance and overall wellbeing in physically active adults. Tiger Milk Mushroom (Lignosus rhinocerus) is a medicinal mushroom traditionally used in Southeast Asia for promoting health and vitality. Previous laboratory and clinical studies have suggested that Tiger Milk Mushroom possesses antioxidant, anti-inflammatory, and immunomodulatory properties that may support physical function, exercise recovery, and overall health. In this randomized, double-blind, placebo-controlled trial, 60 physically active adults aged 18 years and above will be randomly assigned to receive either Tiger Milk Mushroom supplementation or a matching placebo for 12 weeks. Participants in the intervention group will consume one capsule of Tiger Milk Mushroom twice daily, while participants in the placebo group will consume matching placebo capsules following the same schedule. Assessments will be conducted at baseline, week 6, and week 12. The study will evaluate physical performance through measurements of muscle strength, heart rate, self-paced walking performance, perceived exertion, and aerobic capacity (VO₂max). Blood samples will be collected to assess biomarkers related to cardiovascular endurance, exercise recovery, inflammation, and general health, including cortisol, total iron-binding capacity, creatine kinase, interleukin-2, and interleukin-6. Participants' stress levels and overall wellbeing will also be assessed using validated questionnaires. The purpose of this study is to determine whether Tiger Milk Mushroom supplementation can support physical performance, exercise capacity, recovery, and overall wellbeing in physically active adults.

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.

Active Schools in Chile: Impact on Fitness, Physical Activity, and Sports Participation

Study Rationale: Currently, a significant proportion of children in Chile do not meet recommended physical activity levels, which may adversely affect their health and development. The school environment provides an ideal setting to promote healthy habits. This study was designed to evaluate whether a school-based program incorporating physical activity, sports, and health education can improve physical fitness and increase the time children dedicate to physical activity practice. Objective: The primary objective of this study is to evaluate the impact of a two-year school-based intervention on physical activity levels, muscular fitness (measured by upper body, lower body, and abdominal muscular strength), and sports participation among Chilean schoolchildren. How the study works: This is a single-arm cluster intervention study incorporating a pre-post design. Participating schools were allocated in a specialized program focused on physical activity and the promotion of sports practice throughout two school years. What was measured: At baseline and after the two-year intervention, the following outcomes were assessed: Physical Activity Levels: Measured via accelerometry; Muscular Fitness: Assessed through muscular strength tests, including upper limb strength (handgrip strength using a dynamometer), lower limb strength (standing long jump test), and abdominal strength (60-second curl-up test). Sports Participation: Evaluated through self-reports of involvement in organized sports. Researchers compared pre- and post-intervention data between the intervention to determine if children in the special program showed significantly greater improvements compared to those in the standard routine.

Acute Effects of Different Warm-Up Protocols in Amateur Basketball Players

Brief Summary This randomized controlled trial will compare the immediate effects of three warm-up protocols on physical performance in male amateur basketball players. A total of 45 licensed basketball players aged 15 to 25 years will be randomly assigned to one of three groups: standard dynamic warm-up, dynamic warm-up followed by classical hold-relax proprioceptive neuromuscular facilitation (PNF) stretching, or dynamic warm-up followed by short-duration self-administered PNF stretching. The main outcome will be the change in countermovement jump height. Additional outcomes will include flexibility, knee range of motion, squat jump height, 20-meter sprint time, agility, dynamic balance, and perceived exertion. Measurements will be performed before the assigned warm-up protocol, immediately after the protocol, and 15 minutes after the protocol. The study aims to determine whether short-duration self-PNF stretching can improve flexibility while preserving performance more effectively than classical PNF stretching. Each participant will complete the assigned protocol and all assessments during a single study session.

Effects of Policosanol and Exercise on Fitness and Lipids in People With Elevated Blood Lipids

This study will evaluate the effects of policosanol supplementation, concurrent exercise training, and their combination on physical fitness, muscle recovery, inflammatory markers, and blood lipid profiles in adults with elevated blood lipids who are not currently indicated for lipid-lowering medication. Participants will be randomly assigned to one of four groups for 12 weeks: policosanol plus exercise training, policosanol alone, placebo plus exercise training, or placebo without structured exercise training. Participants assigned to the supplementation groups will take policosanol 5 mg per day, while those assigned to the placebo groups will take a matching placebo. Participants assigned to the exercise groups will complete a standardized concurrent exercise training program combining aerobic and resistance exercise. The study will compare changes in physical fitness, lipid profiles, and selected blood biomarkers before and after the intervention. The findings may help determine whether low-dose policosanol, alone or combined with exercise training, can support cardiometabolic health and physical fitness in adults with dyslipidemia.

Effect of Aerobic Exercise Training on Cardiorespiratory Function in Patients With Traumatic Brain Injury

Background: \- Many people who have traumatic brain injury (TBI) have low levels of physical fitness. Low physical fitness causes severe fatigue that reduces the ability to perform routine daily activities, and may also cause increased depression, anxiety, or sadness. Aerobic exercise, such as treadmill walking or running, improves physical fitness in most people and may also decrease fatigue and improve mood. However, more information is needed to determine if exercise improves these conditions in people who have TBI. Objectives: \- To examine the effect of an aerobic treadmill walking exercise program on physical fitness, fatigue, and mood in people with TBI. Eligibility: \- Individuals between 21 and 45 years of age who had a nonpenetrating traumatic brain injury at least 6 months before participating; able to understand oral and written English language, give informed consent and sign a consent form; are physically inactive (including activities related to both job and recreation); and are able to stand and walk on a treadmill safely without help. Design: * This study requires 4 testing visits and 36 exercise visits over 14 weeks. * The first and third testing visits will last about 4 hours and the second and final testing visits will take about 2 hours. * Testing visits will consist of a medical history and physical examination, completion of questionnaires (about fatigue, daily physical activity, sleep quality, mood, and overall quality of life), tests of thinking and a treadmill exercise test. * Participants will have treadmill exercise training 3 days per week for 12 weeks. Each session includes a check-in, warm-up, treadmill walking at the training heart rate, and cool-down. Thirty-two of the sessions will last for about 1 hour, and four of the sessions will include questionnaires to fill out and will last about one-and-a-half hours. * After completing the exercise training program, participants will have a final testing visit to complete the questionnaires (about fatigue, daily physical activity, sleep quality, mood, and overall quality of life), tests of thinking and a treadmill exercise test.

Effects of Magnesium and Spinning Training on Echocardiographic, Inflammatory, and Aerobic Outcomes

Regular aerobic exercise may improve cardiorespiratory fitness while modulating systemic inflammation and oxidative stress. Spinning, as a structured indoor cycling modality, provides a practical aerobic exercise model with adjustable intensity and duration, but its effects on redox balance, inflammatory status, aerobic capacity, and cardiac functional parameters may vary according to individual recovery and nutritional status. Magnesium is an essential micronutrient involved in energy metabolism, muscle contraction-relaxation, ion regulation, and inflammatory and oxidative pathways; therefore, magnesium use may be relevant to exercise adaptation and recovery. This study aims to evaluate the associations of magnesium use and spinning training with oxidative stress, inflammation, aerobic capacity, and cardiac parameters. In this context, biochemical markers related to oxidative/antioxidant status and inflammation, aerobic performance indicators, and echocardiographic cardiac function parameters will be assessed together. The study is expected to provide real-world evidence on whether magnesium use in individuals participating in spinning training is associated with more favorable redox, inflammatory, aerobic, and cardiac profiles.

Mobile-Based Gamified Physical Activity in Secondary Education

Physical activity (PA) is critical for children's physical, psychological, social and cognitive health. The World Health Organisation (WHO) recommends that children aged 5-17 engage in 60 minutes of moderate-intensity physical activity per day. However, 81% of children worldwide, 58% of children in Turkey, and 80% of adolescents do not meet these recommendations. Physical inactivity increases the risk of cardiovascular disease, obesity, and metabolic disorders, causing millions of deaths each year. Therefore, school-based interventions offer an important opportunity to improve children's PA, health-related physical fitness, and physical literacy (3F) levels. In recent years, the concept of physical literacy and mobile-based gamification applications have come to the fore. Gamification increases motivation and improves PA levels through elements such as points, badges, levels, and leaderboards. The literature indicates that gamified applications have positive effects on step count and exercise habits. However, research on physical fitness and literacy dimensions remains limited. In this context, the aim of the project is to examine the effects of a 12-week gamified mobile-based physical activity programme on 3F in secondary school students. The research will be conducted with 54 students at a state secondary school in Bursa, and participants will be divided into three groups: the gamified experimental group (GE), the non-gamified experimental group (NG), and the control group (CG). The physical activity programme will consist of daily step targets and weekly exercises, and students will be monitored via the mobile application called 'Time to Move' and a portfolio notebook. The gamification group will use points, badges, levels and a leaderboard, and physical activity homework will also be assigned outside of school. The study will include pre-tests, post-tests and 12-week follow-up measurements. The unique value of the project lies in fostering PA habits through a gamified mobile application, determining 3F levels and examining their effects on these levels, and ensuring the sustainable monitoring of a school-based programme with the support of a mobile application and portfolio. The main objective of the research is to support behavioural change in secondary school students, make PA a lifestyle, and foster healthy living habits in the long term.

Effects of Moderate-intensity Interval Aerobic Exercise (MIIAE) on Inflammatory, Immune, Metabolic, Physical Fitness, and Quality of Life Parameters in Breast Cancer Patients Undergoing Radiotherapy.

Breast cancer and its treatment with radiotherapy may be associated with systemic inflammatory, hematological, cardiac, body composition, functional and quality-of-life alterations. Exercise has emerged as a non-pharmacological strategy with potential benefits during oncological treatment; however, further evidence is needed regarding the effects of supervised moderate-intensity interval aerobic exercise during radiotherapy. This randomized controlled trial aims to evaluate the effects of a supervised moderate-intensity interval aerobic exercise programme on systemic inflammatory and immune-derived hematological indices, cardiac biomarkers, body composition, muscle strength, lower-limb power, sleep quality and breast cancer-specific quality of life in women with breast cancer undergoing radiotherapy. Participants will be allocated to either an experimental group performing supervised moderate-intensity interval aerobic exercise during radiotherapy or to a control group receiving usual care without structured exercise during the study period. Outcomes will be assessed at baseline and after completion of the intervention period.

SUSTAINA Study: Effects of Sustainable Diet and Therapeutic Exercise on Health in Young Athletes

The SUSTAINA study aims to evaluate the effects of sustainable dietary programs combined with individualized therapeutic exercise on metabolic health, body composition, and musculoskeletal function in young athletes. Participants will be randomly assigned to different intervention groups receiving tailored exercise training and nutritional guidance based on Mediterranean diet principles. The study will assess physiological, anthropometric, and functional outcomes to identify effective strategies for preventing metabolic and musculoskeletal disorders.

Comparison of the Cognitive, Dual-task and Physical Effects of 6 Programs With Older Adults

While the association of physical and/or motor and/or cognitive components with training can generate synergistic effects and thus create an efficient cognitive enrichment program, very few studies have focused on finding an optimal combined program for older adults. According to the model of Herold and his colleagues, there are two modalities of simultaneous combined training: Thinking While Moving (TwM), when the additional cognitive task is not linked to the motor task, and Moving While Thinking (MwT), when the cognitive task is integrated into the motor task. They assume the latter approach is the most promising for improving cognitive reserve. Nevertheless, to the investigators' knowledge, only one study has compared these two modalities in older adults and none has broadened the question by comparing several MwT trainings. The goal of this interventional study will be to compare the cognitive, dual-task, and physical effects of 6 physical and/or cognitive programs in healthy but inactive older adults. The main questions it will aims to answer are: * Will the Moving While Thinking and Thinking While Moving programs have the same effects? * If they have different effects, which will be the best way to improve cognitive, dual-task, and physical functions? The study is being set up between 2023 and 2025 to compare the cognitive, dual- ask and physical effects of 6 programs (3 months, 2 sessions of 1 hour per week). Three experimental MwT programs will be studied: Immersive and interactive wall exergames (I2WE), Complex Cognitive and Motor Activities (2CMA), and exergames with Switch (EXER). They will be compared to an experimental TwM program of stationary bike simultaneous to the Switch (Video games + bike) and 2 control programs: inactive video games (VG) and stationary bike (BIKE). A control group (CON) will be also created. Cognitive, dual-task, and physical pre-tests (before the program), post-tests (after the program), and retention tests (3 months after the end of the program) will be realized to evaluate the effects of the programs.

Effects of 8-Week CrossFit-Based Concurrent Training on Fitness, Body Composition, and Psychological Outcomes in Schoolchildren

This study examines the effects of an 8-week CrossFit-based concurrent training program in boys and girls aged 7 to 11 years, comparing an experimental group (n=15) with a control group (n=15). The aim is to assess changes in strength, cardiorespiratory fitness, body composition, and psychological variables such as anxiety, stress, and self-esteem, using field-based physical tests (CMJ, Course Navette, handgrip strength, etc.) and validated questionnaires. The study follows a randomized controlled trial design with pre- and post-intervention assessments. The experimental group will complete two weekly CrossFit sessions adapted for children, while the control group will maintain their usual routine without structured physical training. The hypothesis states that the intervention will significantly improve both physical performance and psychological well-being in the experimental group compared to the control group.

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.

"11 for Health" in Pakistan - Effects on Physical Fitness, Health Knowledge and Well-being of 8-14-year-old Schoolchildren

This study examined the effects of a school-based football intervention, the "11 for Health" (11fH) programme, on cardiorespiratory health, musculoskeletal fitness, health knowledge and well-being among Pakistani school children. The main questions it aimed to answer were: * Does the programme enhance Pakistani schoolchildren's cardiorespiratory health and physical fitness, including blood pressure, resting heart rate, aerobic capacity, horizontal jumping ability, agility, 30-m sprint, postural balance, BMI and waist circumference? * Does it improve their health knowledge and well-being? Researchers compared students who participated in the "11 for Health" intervention to those who continued their regular school curriculum. 254 fifth- and sixth-grade students (126 boys, 128 girls) from five schools in Islamabad participated in this study, allocated to an 11-week intervention group, a 5-week intervention group, and a control group. Researchers tested all groups before and after the intervention. Cardiorespiratory health and physical fitness were assessed with standardized tests. Health knowledge and well-being were measured with validated Urdu questionnaires.

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.

"Xuong Tan Lac Than" Exercise for Range of Motion and Muscle Endurance

The goal of this clinical trial is to learn the effects of the "Xuong tan lac than" exercise on range of motion and muscle endurance in healthy volunteers. The main questions it aims to answer are: * Does practicing the "Xuong tan lac than" exercise improve joint range of motion (cervical spine, lumbar spine, shoulder, elbow, wrist, knee, and ankle)? * Does the exercise improve muscle endurance around these joints? 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.

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.

Physical Fitness Assessment in Professional and Amateur E-Sports Players

The aim of this observational cross-sectional study is to compare the physical fitness characteristics of professional and amateur e-sports players and to determine whether differences exist between the two groups in terms of physical fitness parameters.
