Randomization will be implemented using SPSS 25.0 (IBM Corporation, Armonk, NY, USA) to ensure balanced group allocation. All outcome measures will be assessed at baseline and post-intervention.

GENESIS: Genotype Guided - Natriuretic Peptides - Cardiometabolic Health Study

Natriuretic Peptides (NP) are hormones produced by the heart, and they have a wide range of favorable metabolic benefits. Lower levels of these hormones are associated with an increased likelihood of the development of diabetes and poor cardiometabolic health. Obese and Black individuals have \~30% lower levels of NP and are at a greater risk of developing cardiovascular (CV) events as compared to lean and White counterparts. Some people have common genetic variations that cause them to have \~20% lower NP levels. Similar to other low NP populations, these individuals with low NP genotype (i.e., carrying a common genetic variation called rs5068) are at a greater risk of developing cardiometabolic diseases. By understanding the NP response following the exercise challenge and the glucose challenge in individuals with genetically lower NP levels will help us understand how to improve cardiometabolic health in them.

Simplified Exercise-based Risk Assessment in Lung Cancer

Physiological evaluation is part of the preoperative risk estimation in patients with lung cancer, and it aids in the choice of treatment. Ventilatory efficiency during exercise has emerged as a strong predictor of major postoperative complications, so far determined during a maximal cardiopulmonary exercise test. However, this test is limited by its availability and high cost, due to the requirement of high-technological equipment and advanced expertise. The current project aims to evaluate a simplified and accessible method for risk evaluation before decision on treatment in lung cancer. It builds on recent advances in technology and knowledge and combines a simple, low-intensity cycling test with measurement of ventilatory efficiency (end-tidal carbon dioxide pressure) with a handheld monitor. In a prospective, multi-center design the investigators will include patients evaluated for suspected lung cancer. The main objective is to establish threshold values for end-tidal carbon dioxide associated with low respectively high risk of major complications in patients undergoing surgery. In addition, the study aims to determine if end-tidal carbon dioxide can predict severe side-effects during neoadjuvant or curatively aiming systemic therapy. The project is closely linked to clinical practice, and the results can be easily implemented due to the simple and cost-efficient methodology. the suggested simplified approach would also allow access to physiological evaluation where more advanced methods are unavailable.

Participants aged 18-40 years will be randomly assigned to one of three groups: a digital rehabilitation group, a face-to-face exercise group, and a physical activity counseling group. The intervention will last 8 weeks, with exercise performed three times per week. Outcomes will include DNA methylation, hormonal and metabolic parameters, anthropometric measurements, body composition, muscle strength, basal metabolic rate, physical activity level, quality of life, menstrual cycle regularity, exercise adherence and satisfaction.

Implementation Facilitation of Exercise is Medicine Greenville

A public health priority exists for the U.S. healthcare sector to integrate physical activity (PA) as a part of the patient care model. This research will provide valuable information on facilitating optimal implementation of a clinic-to-community model that identifies, refers, and enrolls physically inactive patients to community-based PA programs for the prevention and treatment of chronic diseases. Further, this work will provide evidence on the cost-effectiveness of integrating PA in healthcare systems as a population health management strategy.

Effects of Physical Exercise and a Nutritional Supplement on Body Composition, Metabolic Function, and Overall Health in Adults With a Metabolically Challenging Profile

Early-onset metabolic disturbances (such as mild hyperglycemia, subclinical dyslipidemia, excess body fat, and reduced functional capacity) represent one of the major public health challenges among middle-aged and older adults. Although body mass index (BMI) remains the primary clinical criterion for classifying excess weight, growing evidence indicates that BMI does not adequately discriminate cardiometabolic risk, particularly in individuals classified as overweight who present elevated body fat levels (Wu et al., 2024). Several studies have identified altered metabolic phenotypes that do not meet the criteria for obesity, including the so-called "metabolically unhealthy normal weight" (MUNW) or "metabolically unhealthy non-obese" phenotypes. These individuals are characterized by excess body fat, central adiposity, and alterations in glucose and lipid metabolism despite having a non-obese BMI (Stefan, 2020). This profile is associated with increased insulin resistance, low-grade systemic inflammation, and elevated cardiovascular risk, underscoring the need for targeted interventions in "metabolically challenged" individuals. Xiong et al. (2024) demonstrated that metabolic health status independently predicts cardiovascular risk, even when BMI is within non-obese ranges. This evidence supports the rationale of the present project: to intervene in a group of adults without clinical obesity (BMI \< 30 kg/m²) but presenting at least two indicators of mild metabolic dysfunction. Nutritional supplements with thermogenic properties that promote fat oxidation and satiety-such as phenylcapsaicin, an analog of capsaicin designed to improve bioavailability and reduce pungency, thereby enhancing tolerability in adults-may offer a promising complementary strategy. Recent studies have shown that low doses of phenylcapsaicin were sufficient to increase fat oxidation during exercise, reduce respiratory exchange ratio, and lower maximal heart rate during submaximal testing compared with placebo (Jiménez-Martínez et al., 2023a). Furthermore, additional research reported that phenylcapsaicin improved strength performance, reduced perceived exertion, and attenuated markers of muscle damage following resistance training (Jiménez-Martínez et al., 2023b). These findings suggest that thermogenic and fat-oxidation-enhancing supplementation may act as a safe and effective metabolic modulator, particularly when combined with exercise, positioning it as an innovative strategy for adults presenting mild metabolic risk. The present study would integrate: (1) a multicomponent functional exercise program designed to improve strength, balance, and aerobic capacity in older adults; (2) a thermogenic and fat-oxidation-enhancing nutritional supplement as a safe metabolic activation strategy; (3) a standardized dietary control protocol to isolate the specific effects of the supplementation; (4) dual-energy X-ray absorptiometry (DXA) for precise body composition assessment; (5) hormonal and lipid biomarkers to evaluate underlying physiological mechanisms; and (6) validated questionnaires addressing quality of life, sleep, and appetite to capture the holistic dimension of this stage of adulthood. This multidimensional approach would provide an innovative intervention for a growing yet underexplored population: non-obese but metabolically challenged adults at increasing cardiometabolic risk.

This study plans to learn more about heart function among individuals with chronic obstructive pulmonary disease (COPD). In particular, the investigators want to understand the different patterns of right ventricular response to pulmonary hypertension (high pressure in the lungs) during rest and moderate- vs high-intensity exercise. By identifying patterns of right ventricular dysfunction, this study will help identify better treatments for patients with COPD in the future.

The Effectiveness of BETY in Knee Osteoarthritis With Intra-Articular Injections

Osteoarthritis (OA) is the most common condition in middle-aged and elderly populations; it causes pain and physical disability and is characterized by cartilage degeneration, changes in bone tissue, inflammation of the synovial membrane, and an increased inflammatory response. Because pain and depression often co-occur in individuals diagnosed with OA, the concepts of disability and health-related quality of life caused by the disease have become more decisive than radiological joint damage. The chronic nature of the disease, like other chronic conditions, encompasses a range of biopsychosocial impacts, including pain, fatigue, sleep disturbances, functional loss, anxiety, depression, and social isolation. This complex structure is accompanied by a pattern in which inflammatory processes are triggered. Recently, intra-articular injections (such as Platelet-Rich Plasma Therapy (PRP), Hyaluronic Acid (HA), PRP+HA combinations, Corticosteroids, Prolotherapy, and Stem Cells) have been accepted as a treatment for OA. Regarding the mechanism of these intra-articular injections, it has been reported that a combination of various anabolic and anti-inflammatory cytokines may treat inflammation associated with the early stages of OA. It has been demonstrated that, through the effects of various growth factors, these treatments have a positive impact on chondrogenesis and mesenchymal stem cell proliferation by increasing anti-inflammatory mediators and reducing pro-inflammatory mediators. Bilişsel Egzersiz Terapi Yaklaşımı - BETY (Cognitive Exercise Therapy Approach in english) is an exercise approach based on the biopsychosocial model. BETY consists of innovations in function-oriented body stabilization exercises (FoGSE), chronic pain management (BETY-Nociplastic Pain Management (BETY-NPM)), emotion-mood information management (dance therapy-authentic movement), and sexuality information management. The aim of this study is to investigate the effectiveness of BETY, which is often initiated following intra-articular injections-a treatment frequently chosen for individuals diagnosed with knee osteoarthritis (OA).

Impact of Immersive Virtual Reality (IVR) on Respiratory Effort: A Pilot Study in Healthy Adults

This pilot randomized crossover study will evaluate the acute effects of immersive virtual reality (IVR) on respiratory effort during submaximal exercise in healthy adults. Dyspnea and increased respiratory effort are influenced not only by mechanical and metabolic factors, but also by emotional and central neural inputs. IVR has shown potential to reduce anxiety, promote relaxation, and modulate physiological responses, but its direct effect on respiratory effort has not been adequately studied. Healthy adults will complete two experimental exercise sessions: one session with IVR and one session without IVR, in randomized order. In both conditions, participants will perform a 6-minute constant-load cycling test at a submaximal workload individualized from a prior incremental exercise test. Respiratory effort will be assessed continuously using esophageal pressure monitoring. Additional measurements will include ventilatory variables, perceived dyspnea, acute state anxiety, heart rate, oxygen saturation, and heart rate variability. The primary aim is to determine whether IVR reduces respiratory effort compared with the control condition. This pilot study is intended to provide physiological evidence on the potential role of IVR as a non-pharmacological strategy to modulate respiratory effort and dyspnea, and to inform future research in clinical populations.

Virtual Assistant for Exercise Adherence in Older ADULTS

This study will evaluate the effectiveness of a virtual assistant-guided exercise program to improve adherence in older adults. In a nonrandomized controlled clinical trial, the experimental group will complete a 12-week, home-based program (60-minute sessions, 3 times per week) supported by a virtual assistant (BOT). The control group will comprise community-dwelling older adults already engaged in the municipal program Enguera se saludable, which delivers an in-person exercise program of comparable frequency and duration. The primary outcome is exercise adherence, defined as the proportion of prescribed sessions completed. Secondary outcomes include muscle strength, balance, functional capacity, health-related quality of life, and the user experience and usability of the virtual assistant.

Impact of Circadian Exercise on Metabolic Dysfunction-Associated Steatotic Liver Disease in Postmenopausal Women

Type of Study: Clinical Trial Goal: The goal of this clinical trial is to investigate how performing exercise at different times of day (morning vs. evening) affects liver fat, cardiometabolic health, and gut microbiota in postmenopausal women. Participant Population/Health Conditions: The study will involve 63 sedentary postmenopausal women (aged 45-75) diagnosed with metabolic dysfunction-associated steatotic liver disease. Main Questions: The main questions this study aims to answer are: * Does morning exercise reduce hepatic fat more effectively than evening exercise? * How does time-of-day-specific exercise influence cardiometabolic markers? * Do changes in gut microbiota contribute to the metabolic effects of exercise timing? Participants Will: Be randomized into one of three groups: morning exercise, evening exercise, or a usual-care control group. Follow the assigned regimen for 12 weeks. The exercise groups will perform supervised aerobic and resistance training three times per week. Provide blood, stool, and imaging data before and after the intervention to determine the effects of the intervention. Comparison Group: Researchers will compare the effects of morning vs. evening exercise (and usual care) on hepatic fat reduction and cardiometabolic improvement, as well as changes in gut microbiota.

Fasted vs. Fed State Exercise

Although many medications exist for both heart disease and obesity, cost, lack of access for all people, side effects and the desire for a more natural solution have left many people seeking lifestyle treatments such as exercise. Scientists know that exercise is highly beneficial for heart health. When exercise also produces weight loss, these benefits are much improved. Although using exercise to treat or prevent heart disease / obesity is recommended, not all people respond well. Some see significant weight loss and health improvements while others see little changes. For these reasons, new strategies surrounding the use and design of an exercise program are needed. One such strategy could be performing aerobic exercise before breakfast (fasted exercise). When exercising fasted, food/energy stores are low, and one relies on stored body fat for energy. This may help heart health and weight loss. This has never been tested in a program long enough to see such changes. This study will, for the first time, assess the effects of a 16-week aerobic exercise program performed fasted compared to after eating. Outcomes will include blood fats, blood pressure, fat-burning abilities and weight loss. Starting an exercise program can also make people to eat more. This limits the success of exercise. The study will also evaluate ways fasted exercise could change eating, as it possible that fasted exercise could also cause people to eat more, which would limit weight loss and health improvements.

Effectiveness of Kinesiotaping and Peloidotherapy in Carpal Tunnel Syndrome

Patients diagnosed with mild and moderate idiopathic CTS will be randomly divided into three groups. Patients who received 15 sessions of peloid therapy along with a home exercise program will constitute the first group. The second group will consist of patients who received a total of 6 sessions of kinesiotaping twice a week along with a home exercise program. Patients who were given only a home exercise program will be included in the third group. "Patients will be evaluated in detail in terms of clinical examination and outcomes three weeks after the end of treatment and again at three months.

Obesity and Aging: Impacts of Nutritional Counseling and Physical Exercise on Telomeres and Senescence Parameters

The study will involve 80 elderly women, 40 eutrophic and 40 obese, divided into four groups, each with n=20. 1) Eutrophic Group (EG) undergoing only nutritional counseling (NC), 2) Eutrophic Group with NC and combined training (CT), 3) Obese Group (OG) undergoing only NC, and 4) Obese Group with NC and CT. The study will be divided into two main phases: an initial 9-week phase dedicated to NC, followed by a 20-week CT phase.

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.

Multimodal Intervention for Early Chronic Kidney Disease in Young People: Dysbiosis and Inflammation (CKD)

Chronic kidney disease (CKD) is a progressive condition associated with substantial morbidity, mortality, and healthcare costs. Early detection and timely intervention are critical to modify disease trajectory, particularly in adolescents and young adults. Emerging evidence supports the role of the gut-kidney axis in CKD progression, whereby intestinal dysbiosis contributes to systemic inflammation and accumulation of microbiota-derived uremic toxins. This randomized controlled clinical trial aims to evaluate whether a multimodal intervention consisting of a controlled diet, structured exercise, and a symbiotic administered for 180 days improves uremic toxin burden, systemic inflammation, and early renal outcomes compared with standard care plus placebo.

Postnatal Exercise to Activate Baby's Brown Fat

The purpose of this study is to learn how exercise and physical activity during pregnancy and after pregnancy may affect the composition of breastmilk. Certain changes in breast milk after exercise may have an impact on how infants use energy. Understanding this process may improve public health recommendations for exercise during and after pregnancy. This study can help investigators learn more about how maternal exercise patterns may affect body growth and obesity risk in infants who are breastfed. This research may help identify how different factors can influence healthy weight and early development in infants.

Telerehab Exerbrain: Bridging Physical and Cognitive Therapy in Stroke

The goal of this clinical trial is to learn if a web-based exercise and cognitive training (physical-cognitive) program works to improve movements and brain function in adults with long-term stroke. It will also learn whether the program is safe and enjoyable. The main questions it aims to answer are: Does the program improve walking, balance, strength, and reduce fall risk? Does the program improve cognitive skills such as memory, attention, and problem-solving? Researchers will compare the online exercise-and-cognitive training program to usual care to see if the program leads to greater improvements. Participants will: * Be randomly assigned to either the online training group or the usual care group * If in the training group, complete the home-based program for 12 weeks. * Take part in physical and cognitive tests before and after the program

A Study to See if an Energy Drink With Caffeine and Green Tea Increases Fat Burning When Exercising

The goal of this study is to evaluate the influence of consuming a drink containing a combination of caffeine and green tea extracts on fat oxidation responses at rest, during and after a period of endurance type exercise.

Qigong and Multicomponent Exercise in Panic Disorder

Panic disorder is a psychiatric disease characterized by recurrent panic attacks that occur in expected or unexpected situations and create feelings of intense fear, restlessness and discomfort. Panic disorder often has a chronic course, its frequency and severity can be irregular, various physical, mental, and behavioral symptoms can develop, and the quality of life of individuals can decrease significantly. Evidence-based psychotherapy and pharmacotherapy are effective in reducing the symptoms of panic disorder and managing the disorder. However, both of these treatment methods have certain limitations, and approximately one-third of patients do not respond to therapy or the response is not sufficiently effective. Delaying treatment of the disease results in a poor prognosis and more established symptoms. Exercise can be viewed as a low-cost, supportive treatment for relieving symptoms with comparable efficacy to medication and other psychological interventions. Although exercise is recommended for patients with anxiety-panic disorder, there remains uncertainty about whether its effects are sustainable, the type and intensity of exercise required for effective treatment, and thus the effects of qigong and multicomponent exercise on multiple health outcomes in panic disorder. The aim of this study is to examine the effects of Qigong exercise training and multicomponent exercise training on anxiety-panic, balance, mobility, walking, functional strength, physical activity, sleep quality, fatigue, chronic musculoskeletal pain, quality of life and cognition.
