Step-Aerobics Versus Core Exercise for Non-HDL Cholesterol Reduction in Sedentary/Obesity Women

This study investigated the effects of a step-aerobics program versus a core exercise program on serum non-HDL-C levels and other cardiometabolic parameters in sedentary women with overweight/obesity.

Exercise-induced Hypoalgesia and Proprioceptive Changes, Comparing Isometric to Isotonic Neck Exercises

Exercised induced hypoalgesia (EIH) (reduction in pain) after exercise has been studied in the literature, but no comparisons have been made specifically looking at different types of exercise (isometric/dynamic moving through a range of motion with resistance versus isotonic/applying static resistance to a joint not moving) with neck muscle strengthening. This study will explore to see if one form of exercise is superior to the other in providing EIH. Another benefit of exercise is improving proprioception (knowing where our body is in space). Again no specific investigation has been done comparing isometric versus isotonic exercises for neck muscles. Both of these exercises are often prescribed in physical therapy so further understanding the benefits of them can help improve the prescription of exercises for patients.

Effects of BFR-training on Stem Cells and Immune Cells in Human Skeletal Muscle

In this 3-year project, investigators will first measure stem cells (primary outcome) and immune cells (secondary outcome) in human skeletal muscle immediately after and 24 hour after the BFR-training. In the second and third year, the effect of β-NMN (vitamin B3 precursor) and antioxidant on the same outcomes after BFR-exercise will be assessed. The BFR-exercise in the study will consist of a 5 × 10-second sprinting with maximal voluntary efforts, 5 minutes after a BFR pre-conditioning to legs using pressurized cuffs. In Study 1 (1st year, N = 24, aged 20-30 year), a randomized crossover trial will be conducted to compare the efficacy of sprinting exercise using BFR pre-conditioning at 20 mmHg (control) or 180 mmHg (occlusion). Study 2 (2nd year, N = 24, aged 20-30 years) will be conducted to examine the effect of β-NMN supplementation on the aforementioned outcomes in human muscles using a randomized placebo-controlled crossover study design. Study 3 (third year, N = 24, aged 20-30 years) will be conducted to examine the effect of vitamin C on the same variables immediately after and 24 hours after resistance exercise intervention, using a randomized placebo-controlled crossover study design.

Better Lifestyle Counseling for African American Women During Pregnancy

The purpose of this randomized controlled trial is to establish the effectiveness of a culturally targeted and individually tailored behavioral intervention to promote maternal glucose metabolism in African American women.

Mentoring to be Active for Rural Appalachia Children

The innovative MPBA+F begins with peer-to-peer mentoring followed by structured parental/family support for long-term reinforcement of PA behaviors. Building and reinforcing skills, MPBA+F mitigates resource stressors and strengthens protective factors by providing culturally appropriate knowledge and skills to improve the sustainability of physical activity at home without the use of exercise equipment. By strengthening social support through peer and friendship networks and family-based support, MPBA+F responds to the unique needs of rural Appalachians in a culturally responsive way. This study targets physical activity among children with overweight, obesity, or extreme obesity because rural Appalachian communities identify sedentary activity as a key contributor to the high rates of obesity and diabetes risk among youth.

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 a 12-week T10 Exercise Program on Shooting Performance, Upper Extremity Function, Balance and Reaction Time in Competitive Air Pistol Athletes

Air pistol shooting requires a high level of postural stability, upper extremity neuromuscular control, and concentration to achieve optimal performance. Prolonged maintenance of the shooting position may lead to shoulder muscle fatigue, reduced joint stability, and impaired shooting accuracy. Although sport-specific exercise programs have been recommended to improve physical performance in shooters, the effectiveness of the T10 exercise program has not yet been investigated in this population. This randomized controlled trial aims to evaluate the effects of a 12-week T10 exercise program, in addition to routine training, on shooting performance in competitive air pistol athletes. Secondary outcomes include upper and lower extremity functional performance, balance, muscular endurance, upper extremity stability, grip strength, medicine ball throw performance, and visual and auditory reaction time. Participants will be randomly allocated to either an intervention group receiving the T10 exercise program plus routine training or a control group continuing routine training alone. Assessments will be performed at baseline and after the 12-week intervention. The findings of this study may provide evidence for the effectiveness of a sport-specific neuromuscular exercise program in enhancing shooting performance and physical function in competitive air pistol athletes.

Developing a Nutritional Supplement to Increase Collagen Synthesis in People

The purpose of this study is to test whether a natural product supplement can potentiate the increase in collagen synthesis following the ingestion of collagen protein. The investigators have developed a model of natural (GRAS certified) products that stimulate collagen synthesis, in vitro. The investigators will determine whether the natural product supplement can potentiate the collagen synthetic response to the ingestion of collagen protein. Basal and fed serum will be isolated and these samples will be used to treat human engineered ligaments.

Methodological Study of Exercise and Hypoxic Conditions in Healthy Subjects

The aim of this protocol is to assess physiological responses during various physical exercise protocols (whole-body exercise such as cycling or treadmill running, or localised exercise such as knee extension) and during inhalation of a gas mixtures with various oxygen contents (similar to exposure at high altitude).

The Effect of a Post-operative Exercise Programme Versus Standard Care on Physical Fitness of Patients With Breast Cancer Undergoing Deep Inferior Epigastric Perforator (DIEP) Flap Reconstruction Surgery

All patients undergoing mastectomy for breast cancer should be offered the option of reconstructive surgery. The Deep Inferior Epigastric Perforator Flap or DIEP reconstruction as it is commonly referred to, is becoming the favoured reconstruction by both patients and surgeons as it gives a great cosmetic outcome as well as being a good option for patients who may have to undergo radiotherapy treatment after their surgery. Exercise has been demonstrated in previous research to improve tolerance of treatment (particularly chemotherapy), post operative fatigue and the overall quality of life in patients undergoing cancer treatment. Furthermore, it has shown to improve survival in patients who are being treated for breast cancer. The investigators are undertaking this study to investigate whether a structured exercise programme will improve patients fitness after surgery and ultimately improve their recovery after their reconstructive surgery. To do this, half of the people taking part will be undertaking a structured exercise programme and the other half will not and will be assessing which group recover better after their surgery. Currently, no breast reconstruction patients in Ireland are receiving a formal "exercise prescription" after their surgery so will be looking to see if this helps people recover better before it is made standard care for every breast patient in Ireland.

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 a 12-week Supervised Exercise Program Post Bariatric Surgery on Body Composition, Muscle Strength, and Insulin Resistance

The goal of this clinical trial is to evaluate the impact of supervised training program on body composition, muscular strenght, insulino-resistance profile, heart rate variability and on heart structure and function between 3 to 6 months after mixed bariatric surgery or restrictive bariatric surgery. This study will be conducted in men and women with severe obesity. Respectively for each type of surgery (mixed vs. restrictive), participants will be randomized either to the exercise group or to the control group. For participant randomized in the exercise group, 3 months after the bariatric surgery, they will started a supervised exercise program for 3 months. In contrast, for participant randomized in the control group, they will have consultation with kinesiologist to receive general information about physical activity practice. Each participants will perform 4 evaluations; one before bariatric surgery and 3 after bariatric surgery (3 months, 6 months and 12 months). Thoses evaluations will be assessed at each visit : fasting blood draw, anthropometric measurements, cardiac echocardiography, heart rate variability measurement, mid-thigh and abdominal computed tomography scan, maximal exercise test, six-minute walk test, assessment of lower-limb endurance and strength, assessment of physical activity level and energy expenditure.

Evaluation of the Effectiveness of Capacitive and Resistive Energy Transfer Therapy for Lateral Epicondylitis

This prospective, randomized, double-blind, sham-controlled clinical trial aims to evaluate the efficacy of Capacitive and Resistive Energy Transfer (TECAR) therapy in patients with lateral epicondylitis. Participants will be randomly assigned to either a TECAR plus exercise group or a sham TECAR plus exercise group. Both groups will receive a standardized home exercise program including elbow and wrist range-of-motion, stretching, eccentric strengthening, and handgrip strengthening exercises. The TECAR group will additionally receive active TECAR therapy, while the control group will receive sham TECAR treatment using the same device and treatment protocol without therapeutic energy delivery. Outcome assessments will be performed by a blinded evaluator at baseline, immediately after treatment, and at 1- and 2-month follow-up visits. The study aims to determine whether TECAR therapy provides additional benefits in pain relief, functional improvement, and clinical outcomes when combined with exercise therapy in patients with lateral epicondylitis.

Exercise Intervention for Chemotherapy-Induced Peripheral Neuropathy

Chemotherapy-induced peripheral neuropathy (CIPN) is a common adverse effect of chemotherapy that can negatively impact patients' functional status and quality of life. This study was conducted in two phases among oncology patients receiving chemotherapy at a tertiary care teaching hospital in Chennai, India. Phase I used a descriptive survey design to determine the prevalence of CIPN. Phase II employed a randomized controlled experimental design to evaluate the effectiveness of a structured exercise program in reducing CIPN symptoms among patients with mild to moderate CIPN. Eligible participants were randomly assigned to intervention and control groups. The intervention group received education and supervised exercises involving lower and upper extremity movements, while the control group received routine care. Outcomes were assessed using the Chemotherapy-Induced Peripheral Neuropathy Assessment Scale before and after a 21-day intervention period.

Aconselha + Movimento: Protocol for Online Training on Physical Activity and Sedentary Behavior Counseling

This study aims to develop, implement, and evaluate the effectiveness of an online training program on physical activity and sedentary behavior counseling for primary health care workers. The training program is designed to improve competencies related to physical activity and sedentary behavior counseling within primary health care settings. Health professionals working in primary health care units from selected municipalities in Brazil will be invited to participate. Outcomes related to counseling competencies and professional practices will be assessed before and after participation in the training program.

From Exercise Oncology Research to Clinical Practice

Building on previous research that shows the benefits of exercise, this study aims to find out how best to implement exercise in real-world settings. The study will assess the feasibility and acceptability of an embedding an automated referral tool and an exercise professional into standard cancer care impacts clinician referral and patient uptake of exercise programming. The study will assess how effective the exercise program is at improving patients' physical health, quality of life, symptom management, and overall wellbeing during different stages of their cancer journey (e.g., before treatment, on treatment, after treatment).

Effect of Mobile Health-Based Gamified Long-Term Interventions to Increase Physical Activity on Cardiovascular Risk Factors: Randomized Controlled Study on University Students and Employees

The increasing incidence of cardiovascular disease (CVD) and related mortality is now recognized as a global emergency. CVD risk factors include unhealthy diet, inactivity, dyslipidemia, diabetes, high blood pressure, obesity, smoking, and family history/genetics. Increasing physical activity (PA) is recognized as an essential factor in reducing the risk of CVD. Many studies have emphasized that regular and adequate physical activity significantly reduces the risk of CVD through effects such as lowering blood pressure and cholesterol levels, supporting weight control, and improving diabetes management. Measuring steps/day is used to determine PA, and as technologies have developed, smartphones have become widely used tools. Inactivity and time constraints of modern life make it difficult for people to increase PA levels. Therefore, innovative intervention methods based on mobile health and gamification should be used to improve individuals' physical activity. Gamification is the application of game design elements such as points, badges, leaderboards, and levels in non-game environments. Gamification is increasingly being used to create change, particularly in physical activity and health behaviors. It is recommended to include resistance exercises at least 2 days a week in addition to aerobic activity to maximize health benefits. Recently, the high-intensity circuit training (HICT) program, which combines high-intensity interval training (HIIT) and circuit training (CT), requires less time, combines aerobic and resistance exercises, and uses body weight, has been developed and is used in sports. The main aim of the present study is to examine the effects of 12-week Mobile Health-Based Gamified applications on cardiovascular risk factors among university students and employees. In this direction, it is aimed to increase participants' daily steps and improve their physical activity habits. A total of 105 volunteers aged 18 to 64, including students and employees of Bursa Uludag University, will participate in the study. PACER pedometer and 7 Minute Workout HICT exercise mobile health applications will be used in the study. Subjects will be divided into five equal groups of 21 people each using the closed opaque envelope randomization method. Walking intervention (WG), gamified walking intervention (GWG), walking and exercise intervention (WEG), gamified walking and exercise intervention (GWEG), and control (CG) groups will be formed. The first four groups (WG, GWG, WEG, and GWEG) will walk every day for 12 weeks to reach the set target number of steps. In addition, volunteers in the GWEG and WEG group will exercise (HICT) for at least 15 minutes on 3 designated days per week in addition to walking. In addition, volunteers in the GWG and GWEG groups will use a gamified application. In CG, there will be no regular physical activity, and they will continue their daily lifestyle. In our study, unlike those conducted to date, the application of HICT with gradually increasing physical activity for 12 weeks to reduce CVD risk factors, and the use of gamified methods to stay in the program and ensure sustainability, emphasize its unique value. The gamified exercise program applied in this study is expected to provide an additional benefit for CVD risk factors compared with the protocols used to date.

Physical and Cognitive Aging Study in Older Adults

Hispanic Americans are the fastest growing older adult group in the United States, disproportionally increasing the risk of an Alzheimer's disease and related dementias diagnosis. Efforts to reduce this risk and mitigate the related cognitive/physical declines are critical. The aim of this study is to assess the feasibility of enrolling older adults into an aging trajectory cohort, while generating preliminary data on associations of physical and cognitive aging trajectories. Our secondary objective is to generate preliminary data on the association of standard measures of physical activity and physical function with cognitive status. This study fits within our longitudinal research goal to reduce dementia incidence by understanding the mechanisms that drive the cognitive-physical aging trajectory.

Prehabilitation for Ovarian Cancer Patients

Individuals with ovarian cancer have very poor survival rates. This is because the cancer is not usually detected until it has reached advanced stages. How long an individual survives also is determined by the cancer treatment they receive. Although there are best treatment practices to improve survival, some women have other conditions that limit treatment options. One such condition seen in as many as 50% of women with advanced ovarian cancer is frailty (an age-related decline in function and health). This is a major concern as doctors will often have to change how the cancer is treated based on the patient being frail. For example, patients living with frailty are less likely to have their full tumor removed during surgery. They are also more likely to have complications with surgery, stay in the hospital longer, and recover less well from surgery overall. Patients living with frailty also are more likely to experience delays in their chemotherapy starting, receive lower doses of chemotherapy and/or receive fewer cycles of chemotherapy. These changes in treatment may decrease how long a patient survives after diagnosis. Thus, research is needed to explore strategies to decrease frailty in patients who require treatment for advanced ovarian cancer. An option gaining more attention is physical exercise (e.g. walking, repeatedly rising from a chair). Exercise performed before surgery, which is called prehabilitation, can improve how well a patient recovers after surgery and increase how long they survive. Research has shown that prehabilitation is very beneficial for patients undergoing surgery for heart disease. However, it is not clear whether prehabilitation works for those with advanced ovarian cancer that are going to have surgery. Therefore, the investigators want to explore how a 4+ week exercise program performed while waiting for surgery for advanced ovarian cancer changes frailty and how a patient recovers after surgery. The investigators will specifically look whether the exercise program: 1) reduces how frail a patient is before surgery; 2) improves how well the patient recovers after surgery; and 3) affects the patient's chemotherapy treatment plan. This study will provide important information about the ability of prehabilitation exercise to improve surgical and treatment outcomes in women with advanced ovarian cancer. Overall, it is believed that exercise has the potential to improve the survival of advanced ovarian cancer patients.

Influence of Short-Term Antibiotic Therapy on Exercise

The gut microbiome refers to the trillions of bacteria that inhabit the stomach and other regions involved in the digestion of food, including the intestines. Compelling studies of animals (rodents) suggest that the health of the gut microbiome may influence skeletal muscle function and exercise performance. To date, there have been no similar observations reported in humans. A common experimental approach in animal studies to temporarily disrupt the gut microbiome is through the use of antibiotic therapies. Azithromycin is an antibiotic medicine prescribed to humans for the treatment of mild to moderate infections caused by bacteria. The purpose of the proposed project is to determine the influence of short-term (5-days) antibiotic therapy (azithromycin) on exercise performance in young, healthy adults. Treadmill exercise performance will be compared in two groups of adults before and after 5-days ingestion of azithromycin, or a placebo (something that has no physical effect).

Development of a Chatbot-supported Personalized Exercise Program for Older Adults and Evaluation of Its Effects on Cognitive Functions

The purpose of this study is to develop an artificial intelligence-based chatbot application to support exercise behavior in individuals aged 60 and over who do not regularly exercise, and to evaluate its effectiveness. In addition, the study aims to examine the effects of changes in exercise habits on the cognitive (mental) functions of older adults. In this study, the impact of a chatbot-supported personalized exercise program on cognitive functions in older individuals will be evaluated. A total of 90 participants is planned for inclusion in this study. If you agree to participate in this study, depending on the group you are assigned to, you may receive: * An artificial intelligence-based chatbot program, along with educational materials about the importance of exercise, or * Only educational materials (brochures) prepared by the researchers about the importance of exercise. At the beginning of the study, you will be asked to complete a data collection form. The same form will also be administered at week 12 and week 24. This form will include: * Basic information such as your age and gender, * Questions about your exercise habits, * A brief test to assess your cognitive (mental) functions, * Questions evaluating your level of physical activity. The study duration is 24 weeks, including 12 weeks of intervention and 12 weeks of follow-up.

Home-Based Exercise Programs for Fall Prevention in Parkinson Disease

Falls are common in patients with Parkinson disease and may lead to reduced mobility, fear of falling, loss of independence, and injury. Exercise-based rehabilitation programs may help improve balance, gait, and physical performance in this population. This randomized controlled trial aims to compare the effectiveness of two home-based exercise programs in patients with Parkinson disease: the Otago Exercise Program and a structured home exercise program. Participants will be randomly assigned to one of two groups. Both groups will receive exercise education and will perform their assigned home exercise program for 6 weeks. Participants will be evaluated at baseline, at week 3, and at the end of week 6. The study will assess fall-related outcomes, freezing of gait, functional mobility, gait parameters, postural control, and physical performance. The results may help determine which home-based exercise approach is more effective for reducing fall risk and improving functional outcomes in patients with Parkinson disease.

Creatine and Resistance Training in Older Adults With Mild Cognitive Impairment

The goal of this 26-week trial is to learn if creatine supplementation and resistance training (i.e., weightlifting; exercise that increases muscle mass), alone and together, impact cognition, brain health, and physical function in older adults with mild cognitive impairment. Previous studies have shown that resistance training improves cognition and brain health in older adults. Creatine is naturally occurring in the human body and is known to decline with age. Studies have shown that creatine increases muscle mass and bone density in older adults when supplemented. Some research has suggested that creatine may also improve cognition and brain health. However, little is known about how creatine supplementation affects the aging brain and body alone and when combined with resistance training, especially in those with known cognitive impairment. In this study, participants will be randomly assigned to one of four groups: 1) creatine and resistance training, 2) placebo and resistance training, 3) creatine and active control (balance and tone classes), or 4) placebo and active control. Participants in the creatine groups will take creatine every day during the study. Participants in the placebo groups will take a look-alike substance that contains no drug every day during the study. Participants in the resistance training groups will attend three 60-minute classes per week that target each major muscle group and will increase in difficulty during the study. Participants in the active control group will attend three 60-minute classes per week that will consist of balance, stretching, and range of motion exercises. This group accounts for variables such as physical training received by traveling to the training centres, social interaction, and changes in lifestyle secondary to study participation. Researchers will collect information before and after the 26 weeks to see if creatine supplementation and/or resistance training have any effects on cognition, brain health, and/or physical function. The investigators suspect that both creatine supplementation and resistance training will improve cognition, brain health, and physical function alone. However, it is thought that the combination of creatine supplementation and resistance training will improve cognition, brain health, and physical function more.
