79 Clinical Trials for Various Conditions
The Hawks in Motion (HIM) High Intensity Exercise program is designed to implement the American Physical Therapy Clinical Practice Guidelines and American College of Sports Medicine recommendations for exercise for people with neurologic disability. Doctor of Physical Therapy (DPT) students administer the HIM High Intensity Exercise Program. A prior study evaluated the feasibility, safety, and efficacy of the HIM High Intensity Exercise Program and found it feasible, safe, and effective for 30 people with neurologic disabilities between the ages of 8-99 years. The investigators would like to evaluate whether participation in the HIM High Intensity Exercise Program affects mobility in everyday life. Physical activity will be measured one week before program implementation and one week after to assess if the participants' mobility in everyday improved.
The purpose of this study is to determine whether high-intensity exercise and high-fiber diet are feasible and improve various health outcomes among participants with advanced melanoma receiving immunotherapy. The names of the groups in this research study are: * High-Intensity Exercise (EX) * High-fiber Diet (DT) * Combined High-Intensity Exercise and High-Fiber Diet (COMB) * Attention Control (AC)
The heart and brain are regulated by the autonomic nervous system. Control of these organs can be disrupted in people with spinal cord injury (SCI). This may affect their ability to regulate blood pressure during daily activities and process the high-level information. Previous studies show that high-intensity exercise induces better outcomes on heart and information processing ability in non-injured people compared to moderate-intensity exercise. However, it is unknown the effects of high-intensity exercise on heart and brain function in people with SCI. Therefore, this study aims to examine the effects of a single bout of high-intensity interval training on heart and brain function in this people with SCI compared to age- and sex-matched non-injured controls.
The goal of this interventional study was to test the high-intensity interval training called Aphasia Physical Exercise (APEX) in healthy older adults. The main questions it aimed to answer were: 1. what is the safety and feasibility of APEX? 2. what are APEX's acute physiological effects? 3. what is APEX's effects on functional fitness? 4. what is APEX's effects on cognition? Participants underwent: * Baseline testing session (#1) with cognitive measures only (a week before the Pre-exercise session); * Pre-exercise session (#2) with maximum oxygen consumption and heart rate assessment, functional fitness and cognitive measures (3-7 days before the start of the exercise program); * APEX program, two APEX classes per week for four weeks (eight classes in total); * Post-exercise session (#3), functional fitness and cognitive measures, (0-2 days after the end of the exercise program).
The goal of this clinical trial is to establish the feasibility and fidelity of a high-intensity exercise program for individuals with post-stroke aphasia. The main questions it aims to answer are: * Is it feasible for stroke survivors with aphasia to participate in a long in-person physical exercise program? * Does participation in a physical exercise program lead to physical fitness, cognitive, language and/or psychological changes? Participants can take part in two different physical exercise interventions: * Low intensity intervention (control intervention); * High-intensity physical exercise intervention (target intervention).
People aging with HIV are at higher risk for Alzheimer's disease and related dementias, and although physical activity is a promising target to mitigate such risk, this population engages in low levels of physical activity. Few studies have tested cognitive effects of exercise interventions or examined mechanisms of adherence to long-term exercise among diverse samples of midlife and older people with HIV. The current study will leverage an existing R01 to address these gaps and provide implications for development of personalized approaches for the treatment and prevention of cognitive impairment and dementia in older people with HIV.
This is a single site, randomized exercise trial with individuals at least 50 years of age living with HIV who experience suboptimal cognition. The overall goals of this proposal are to determine whether 16 weeks of structured high-intensity interval training (HIIT) can overcome vascular and cognitive impairments (Aim 1) to a greater extent than continuous moderate exercise. Additionally, investigator will seek to identify barriers to engagement in exercise and the participants' perceptions of the study and exercise interventions (Aim 2). This study will enroll 60 participants in Birmingham, Alabama. Data collection will occur at each visit, with baseline data collected at the initial visit with a 3-month follow-up occurring following completion of the intervention.
This double-blinded, randomized, placebo-controlled, cross-over study is designed to evaluate the potential effects of a fucoidan supplement on the inflammatory and immune responses following high intensity exercise.
The purpose of this graduate student research study is to determine if a high-intensity exercise program can slow or reverse biological (transcriptomic) aging and shed light on the underlying transcriptomic pathways involved.
This pilot study tests the feasibility and preliminary efficacy of an 8-week, 3-arm pilot exercise trial in which 45 breast cancer survivors will be randomized to high-intensity interval training (HIIT; n=15), moderate-intensity aerobic training (MOD; n=15), or Usual Care (UC; n=15).
This is a multi-site, randomized, single-blind (researchers), active treatment concurrent control trial with individuals aged 50-80 living with HIV who experience fatigue and live a sedentary lifestyle. The overall goals of this proposal are to determine whether high-intensity interval training (HIIT) can overcome physical function impairments and increased fatigue (Aim 1) and impairments in mitochondrial bioenergetics of older people with HIV (PWH) to a greater extent than continuous moderate-intensity exercise (CME) (Aim 2). The investigators further seek to determine whether a biobehavioral coaching intervention following either HIIT or CME can promote long-term adherence to physical activity (Aim 3), a crucial component of the sustainability of the intervention. This study will enroll 100 participants in Aurora, Colorado and Seattle, Washington. Data collection will occur at each visit, with baseline data collected at the initial visit. A 3-month follow-up will be conducted over the phone from the date of the final visit. The initial enrollment goal of 100 was increased to 120 in 2023 to facilitate a larger number of participants with key secondary outcomes.
After an initial phone screen process, approximately 50 participants will be enrolled and evaluated/screened in person after consenting to achieve 30 eligible participants with a principal diagnosis of GAD, panic disorder, or social anxiety disorder and high anxiety sensitivity (Anxiety Sensitivity Index score =20). Participants will be given a choice of either high intensity interval training (HIIT) or walking interventions, which will be completed over the course of 8 weeks. The goal of the study is to 1) obtain pilot data comparing the efficacy of HIIT vs. walking for effects on psychiatric, functioning and immune outcomes, 2) to identify adherence levels given the choice of exercise intensity, and 3) to identify proportion of individuals opting for each intervention. Results from this pilot study will be used to inform future grant applications including a K award.
The goal of this study is to identify the comparative efficacy of high-intensity walking training in individuals with chronic, motor incomplete spinal cord injury as compared to lower-intensity walking exercise.
Although current clinical guidelines stipulate that patients with hypertrophic cardiomyopathy should not partake in high intensity exercise (HIE) or competitive sport due to safety concerns, there is no clear evidence to support this notion. In fact, two exercise training interventions in this population indicates that regular moderate to vigorous intensity exercise is efficacious for improving exercise capacity and cardiorespiratory fitness, and does not increase arrhythmia burden or adverse events. Moreover, moderate intensity exercise and HIE training significantly increases cardiorespiratory fitness in patients with cardiac disease. Such improvements are associated with substantial reductions in cardiovascular mortality and might outweigh the risk of adverse events in patients with hypertrophic cardiomyopathy (HCM). Having a genetic cardiomyopathy does not grant immunity against lifestyle related cardiometabolic diseases and inactivity is rife in HCM patients likely due to misinformation/education. It is therefore paramount to further explore the benefits of regular moderate intensity exercise and HIE in patients with HCM for proper therapeutic management of the condition.
The purpose of this randomized, controlled interventional study is to determine the effects of a high intensity exercise training program on objective sleep measures, daytime sleepiness, mobility, and brain health/functional connectivity in patients with Parkinson's disease.
Several animal and human epidemiologic studies have provided evidence that exercise may be neuroprotective in Parkinson's disease (PD). Exercise may forestall diagnosis and, in the case of those who have already been diagnosed with PD, it may slow the observed neurodegeneration. Unfortunately, because this line of research is in early stages, there is little evidence to indicate what biological mechanisms underlie the neuroprotection that is conferred with exercise. Toward this end, it is possible that an interaction between endogenous antioxidant enzymes, inflammatory processes, and reactive oxygen species may be associated with exercise improvements in PD. One of the most common reasons for premature death in PD is falls. Several meta-analyses have concluded that exercise training programs focused on balance and/or strength training are effective at improving aspects of balance. Taken together, the current body of evidence suggests that exercise may be neuroprotective and balance/strength training may decrease the likelihood of a fall. The combination of these efficacious treatment modalities (exercise and balance/strength training) in a comprehensive treatment approach to improve PD symptoms and balance has been previously reported at relatively mild or moderate exercise intensities. Because recent research has suggested that patients with PD may benefit more from more physically intense programs, we are proposing a more aggressive approach with regard to exercise intensity and frequency in the present trial. The primary purpose of this study is to determine the feasibility and safety of a high intensity exercise approach to PD. A secondary purpose is to determine the trajectory of change in outcomes over the duration of the trial from a high intensity fall prevention program. It is hoped that a signal of efficacy will allow this trial to progress to a comparative effectiveness trial. An important innovative design element is collecting biological assays to better understand the mechanism underlying the anticipated clinical improvements. Aim 1 is to test the feasibility of a high-intensity exercise and fall prevention boot camp (HIBC) in patients with PD by analyzing adherence and whether they achieve minimum Centers for Disease Control exercise standards (150 min/wk moderate level aerobic exercise; strengthening at least two times per week) for the duration of the trial. Aim 2 is to determine if participation in an 8-week HIBC under the direction of a physical therapist is safe for individuals with PD. Secondary Aim 3 is to determine if participation in an 8-week HIBC will produce a signal of efficacy for several physical outcomes: falls per physical activity ratio, balance efficacy, motor activity, fatigue, muscle strength, bone health, cognition/mood, and quality of life. Secondary Aim 4 is to determine if participation in an 8-week HIBC will produce a signal of efficacy for biological outcomes, anti-inflammatory cytokines and anti-oxidant enzymes. An additional exploratory aim will be an analysis of BDNF val66val, val66met, met66met polymorphisms to determine if there is a differential response to exercise. This trial is innovative because it utilizes a high intensity comprehensive exercise treatment approach (aerobic exercise, strengthening, and balance training). To our knowledge, there have been no trials of individuals with PD who have participated in a trial of this intensity in a group "boot camp" setting. Another innovative design element is the use of three novel assessments: biological assays of pro- and anti-inflammatory cytokines, endogenous anti-oxidant enzymes and a novel assessment of falls (falls per physical activity ratio). Participants will be randomly assigned into either an 8-week HIBC group or an 8-week usual care control group (standard, low intensity group therapy class) under the direction of physical therapists. Each group will have 15 participants with a 1:5 patient-to-therapist ratio. The HIBC will be 1.5 hours daily, Monday through Friday. Participants will be required to attend 3 out of the 5 days. The protocol of the HIBC will include the following exercise components: A. 30 minutes of moderate-high intensity aerobic exercise; B. 15 minutes of strengthening the major muscle groups; C. 15 minutes of balance training; and, D. 15 minutes of interspersed rest and stretching. Participants will rotate through these four exercise components. Participants will have one baseline test and assessments at the 2-week, 4 week, 8-week, and 6-month points. Outcomes of the primary aims (Aim 1 and Aim 2) will be frequency counts of participation, adverse events, and compliance with exercise. The outcomes for the secondary aims will include measures of balance and falls, physical capacity, fatigue, exercise/physical activity behavior, and biological assays.

The overall goal of the CYCLE-AD trial is to determine the role of long-term, high intensity exercise in slowing or delaying the onset of cognitive and AD-related brain changes in e4 carriers. Successful translation and demonstration of the effectiveness of a scalable home-based exercise intervention capable of slowing or delaying disease onset will transform AD treatment, improve patient outcomes and quality of life, and reduce health care costs.
The goal of this observational study was to better understand the impact of increased plasma volume on later exercise in hypoxia. Investigators examined young, healthy, males who regularly participated in aerobic exercise. Investigators first measured participant's response to exercise in hypoxia (simulated \~7,500 feet above sea level). The investigators then had participants either 1) undergo 1 bout of high intensity interval exercise or 2) undergo 1 bout of moderate, continuous exercise. 48 hours after the exercise, participants were again examined in hypoxia.
The purpose of this study is to validate the LabClasp's ability to estimate blood \[lactate\].
The overall purpose of this pilot randomized control trial (RCT) is to determine the efficacy of the high-intensity interval training (HIIT) exercise protocols for the WheelMill System (WMS) to improve exercise intensity, cardiovascular fitness, metabolic health, and psychological well-being in manual wheelchair users (MWUs) with spinal cord injury (SCI).
The proposed work is designed to be the first in a series of studies investigating the health benefits and risks related to high intensity training (HIT) exercise. Our specific aims are to determine, 1) if participation in a single bout of HIT induces hematological markers consistent with acute kidney injury (AKI), and 2) if risk is predicted by the pre-exercise concentration of plasma proenkephalin-A. This investigation is an observational case control study. In year one, data collection procedures will be refined with \~40 participants local to the University of Wyoming and training will occur for collaborators from Wyoming community and tribal colleges. In year two, data collection will expand to some of the 12 CrossFit® gyms in Wyoming with assistance from the community and tribal colleges. Blood and urine samples will be collected before and up to 48 h after a standardized bout of HIT exercise on \~100 participants. Baseline blood samples will be analyzed for proenkephalin-A. All blood samples will be analyzed for markers of muscle damage (e.g., creatine kinase and myoglobin), and markers of kidney function (e.g., serum creatinine and blood urea nitrogen). Urine will be analyzed for markers of filtration function (e.g., albumin, creatinine, neutrophil gelatinase-associated lipocalin \[NGAL\], and kidney injury molecule 1 \[KIM-1\]). Lastly, the severity of kidney damage will be compared with the number of risk alleles and proenkephalin-A concentration. The investigators envision that the bout of HIT exercise will induce markers consistent with skeletal muscle damage in most participants and, based on literature from other styles of intense exercise, that acute kidney injury will be diagnosable in between 50-75% of participants. Secondarily, the investigators predict that the concentration of proenkephalin-A will be inversely related to the change in kidney function from before to after the HIT exercise bout.
Individuals with obesity and particular type 2 diabetes have abnormally high levels of fat in liver cells and are at increased risk for cardiovascular and liver-related mortality. Prior research has shown that caloric restriction, exercise, and behavior modification can help lower hepatic fat levels in these individuals. Additional research has also shown that exercise independent of weight loss can reduce hepatic fat content in obese humans. The current exercise guidelines do not specify what type or what intensity of exercise is required to induce such reductions in hepatic fat. Thus, the purpose for doing this study is to determine if there are differential effects on liver fat with 4 wk of high intensity intermittent exercise compared with continuous moderate exercise in obese individuals.
The purpose of this study is to determine the impact of high intensity,anaerobic exercise, in the form of cycling, on SCUBA diving. Outcomes are determined by the quantification and subtype of circulating microparticles, complete blood counts, and the quantification of venous gas emboli, measured via transthoracic echocardiography, in the cardiac cavities.
The primary goal of this investigation is to assess whether Solarplast (R) supplementation will improve recovery following heavy resistance exercise in active adults. The primary questions to be addressed are: Does Solarplast (R) decrease muscle damage and inflammation associated with heavy resistance exercise? Does Solarplast (R) reduce the decline in performance associate with heavy resistance exercise? Researchers will compare Solarplast (R) to a placebo (a look-alike substance that contains no active ingredients) to see if Solarplast (R) is effective at improving recovery. Participants will be asked to: Take Solarplast (R) or placebo daily for 4 weeks Visit the laboratory at least once per week to receive their supplement Report to the lab for 3 consecutive visits following supplementation to complete a heavy resistance training session and follow-up testing.
