18 Clinical Trials for Various Conditions
This research on Functional Incidental Training ( FIT) primarily involves women residing in community nursing homes. It is an individualized rehabilitative protocol intended to improve mobility, endurance, strength and continence in frail, older, functionally impaired and disabled veterans. Objectives of the project are as follows: 1) Test the effects of FIT on transfer ability, continence, ambulation/mobility, balance and fall risk, strength, and endurance; 2) Determine the characteristics of NHCU residents who respond to FIT; 3)Identify the most sensitive outcome measures related to FIT; and 4) Determine the labor costs of FIT relative to usual care.
The purpose of this clinical trial is to look at tyrosol's effects on endurance, strength, and fatigue resistance in humans. Additionally, the combination of tyrosol and creatine monohydrate will also be looked at to determine if there is a cooperative effect from using both together. It will be conducted over a 4-week period to compare the effects of the following substances: 1) tyrosol, 2) a placebo (a look-alike substance that contains no drug), 3) creatine, and 4) a combination containing both creatine and tyrosol. Endurance, strength, and fatigue resistance will be compared between groups through repeated testing (described below). Participants who pass initial screening will be invited on-site for day one (Visit 1) of testing where they will proceed with a series of tests which will include the following: (1) body composition; (2) cognitive testing; (3) full-body strength testing; (4) grip strength on both hands; (5) muscle power testing; (6 \& 7) Resting blood lactic acid testing followed by 5RM (repetition maximum) bench press, leading to multiple sets of bench press (based on the previous weight) completed to failure, followed by another blood lactic acid reading; (8) a repeat of the muscle power testing; (9) a 1 mile time trial run completed as fast as possible. After the 4-week supplementation period (\~28-34 days), all original measures will be repeated as before in the same order (Visit 2). Approximately 24 hours later (Visit 3) participants will then repeat all physical testing procedures except tests 1, 6, 7, and 8, to determine physical recovery. Additionally, questionnaires for soreness and perceived recovery will also be completed at the beginning of Visit 2 and 3, and again on its own as the only testing event at 48 hours post-Visit 2 (visit 4).
Physical Inactivity and excessive sedentary behavior are risk factors for diabetes and cardiovascular disease. Movement is important for overall health. This study will assess the validity and usefulness of low risk, non-invasive wellness device, the Gentle Jogger® (GJ) that passively simulates the physical activities of jogging. The study will evaluate whether or not use of GJ modifies glycemic control and muscle strength in subjects who are known to be diabetic and those who are not. The study volunteers are subjects between the ages of 25-80yr.
Health-related physical fitness (HRPF) has demonstrated high clinical relevance, and its level is associated with the ability to perform activities of daily living with vigor and a lower risk of chronic disease. Consequently, exercise prescription guidelines recommend improving HRPF as a focus for prevention and rehabilitation programs. Measuring and tracking HRPF often requires specialized equipment and personnel, which are expensive and less applicable to the general population. Wearables may mitigate this issue by providing useful estimates of the HRPF.
The investigators will conduct a controlled clinical trial with U.S. Army soldiers training to become combat medics. The purpose of this study is to determine if a 11-week, high intensity exercise program targeting the low back muscles using specialized equipment will result in a 25% increase in low back muscular strength and endurance compared with a lower intensity general core stability exercise.
The Step into Support for Endurance and Strength (SISTERS) research study is evaluating whether a mobile health game designed to increase physical activity is feasible and acceptable in patients with gynecologic cancers. -SISTERS is testing a mobile health intervention can help increase physical activity. Participants will be randomized to receive either 1) a Fitbit or 2) a Fitbit + a game + help from a friend or family member whom you chose will help the participant reach their goals. (i.e. a Teammate).
Research is needed to determine safe and effective exercise rehabilitation programs to prevent and improve physical disability in older adults living with HIV. This problem is of great importance to the VA. The majority of the 25 thousand HIV-infected veterans are over 50 years of age (64%). The combined effect of aging and inflammation increase the risk for physical disability in older HIV-infected veterans. This translational exercise training trial will examine the cardiac and skeletal muscle effects of combined aerobic exercise and resistance training to attenuate the functional declines of aging with HIV by reducing the deleterious consequences of chronic inflammation. Findings will guide future rehabilitation research on cardiac remodeling and inflammation of skeletal muscle. The proposed research will advance the goal to develop effective rehabilitation strategies that improve the health of older HIV-infected veterans.

Secondary Objectives: * Determine if a specific exercise regimen (combined strength training/functional endurance) increases the overall ability to perform daily physical activities (ADLs) among women with breast cancer while undergoing adjuvant or neoadjuvant chemotherapy treatment as compared to a control group. * Determine if a specific exercise regimen (combined strength training/ functional endurance) increases mobility in women with breast cancer while undergoing adjuvant or neoadjuvant chemotherapy treatment as compared to a control group. * Determine if a specific exercise regimen (combined strength training/functional endurance) increases endurance in women with breast cancer while undergoing adjuvant or neoadjuvant chemotherapy as compared to a control group.
Thirty active male and female athletes will be recruited for the study. Subjects will be examined at baseline for VO2max performance. Subjects will then be stratified and randomly divided equally (50% - 50%) into an Oceanix (supplemental) or placebo condition such that baseline VO2max match. Once randomization, subjects will be baseline tested for multiple measures of muscle force capacity, muscle soreness, immune function, and endocrine function. Upon completion of baseline testing, subjects will all complete a one-day, cross-training course in Tampa, Florida. The training course is known to be extremely vigorous and causes significant muscle damage. Subjects will then be retested for muscle function at 24, and 48 hours following the course. At 24- and 48-hours subjects will be asked to repeat a simulated time trial race. In this way, we will measure repeated race performance, recovery from intense exercise, muscle damage from exercise, and immune function during multiple races.
STRIVE Cardio is a 12-week exercise intervention study with the goal to improve functional fitness and cardiovascular health for women who have completed treatment for non-metastatic endometrial cancer within the last five years and are currently in remission. Measures will include a functional fitness test, carotid-femoral pulse wave velocity, brachial artery flow mediated dilation, and a blood draw. Participants will be provided resistance bands, a dumbbell, and a Fitbit to keep. Participants will be compensated $50 for each of their two in-person visits.
This study aims to investigate the impact of two plant-based diets-whole food plant-based (WFPB) and plant-based meat alternatives (PBMA)-vs. an omnivorous diet (Animal) on endurance and muscular strength in recreational athletes.

While the use of creatine monohydrate supplementation and its associated benefits are well researched and supported, the impact of the timing of when creatine is ingested is a highly nuanced topic. The potential for the timing of administration to make an impact on observed outcomes is an established and appreciated factor and limited research to date has examined the impact of creatine timing. Of the literature that has been published, one study was very short in duration (4 weeks) that possessed a study design that undermined its practicality, two other studies used older individuals, and one study utilized a unilateral training model which may not be an adequate exercise protocol to allow for the ergogenic potential of creatine to mediate any enhancement of training adaptations. Therefore, based on the limited number of studies in young and previously trained populations, future studies examining the effects of pre vs post-training creatine monohydrate supplementation on resistance training adaptations are warranted.
Frailty is an age-associated clinical condition of poor physiological reserve that increases risks for falls, hospitalization and mortality. Nicotinamide adenine dinucleotide (NAD) is a critical co-factor needed for many cellular processes. The natural levels of NAD decline aging and this has been linked to physical performance decline in animals. Human trials have demonstrated that nicotinamide riboside (NR), a form of vitamin B3, is safe and effectively increases NAD+ levels. In animal studies, NR improves treadmill performance and muscle quality. Here the investigators propose a double-blind randomized control trial to assess the benefits of NR supplementation on human muscle function and physiology. The investigators anticipate the research findings will support the use of this nutritional supplement to improve the health of Veterans during aging.
The investigators have previously demonstrated that burn injury causes severe muscle wasting, weight and height retardation, and systemic protein catabolism in pediatric and adult burned patients. The persistent loss of muscle impairs the quality of life of the burned patients, and it also delays autonomy and reintegration into the community. In 2009, the investigators showed that the daily injection of recombinant human growth hormone (GH) for nine months post discharge significantly increased height and weight, as well as lean body mass, in pediatric burned subjects. Our long-term goal is to improve the quality of life of burn patients by preventing height, weight, and muscle loss that may occur from severe protein catabolism. The objectives of this application are to a) attenuate height and weight in burned patients with the administration of GH, b) prevent or reverse loss of muscle and strength in these patients, and c) collect pilot data about cardiopulmonary parameters, scar assessments, and muscle metabolism. Our central hypothesis is that the administration of GH will restore depleted levels of growth hormone and will lead to prevention of lean body mass loss and bone mineral content, improve rehabilitation, and accelerate reintegration of severely burned patients. The investigators will administer either placebo or GH (daily subcutaneous injections of 0.05 mg/kg/day of GH \[somatropin, Genotropin, Pfizer, New York, NY\] to adult burn subjects (n=31 per group, 18-85 years, \>30% total body surface burns) for nine months beginning one week prior to discharge. Both groups will be studied for a total of two years. The following aims will be tested: 1) determine the effects of GH supplementation on body composition, such as lean body mass loss, muscle strength, and exercise endurance; and 2) assess whether rehabilitation and subsequent reintegration of severely burned patients into society can be accelerated. Investigators will measure changes in lean body mass, muscle strength and exercise endurance during the acute hospital stay, discharge, and long-term follow-up visits (6, 12, 18, and 24 months after burn), as well as secondary endpoints such as cardiopulmonary variables, hypertrophic scar development, quality of life questionnaires, and concentrations of relevant hormones, cytokines, and oxidative stress markers.
In the past, dietary nitrate supplementation has been shown to have clinical benefits in the treatment of cardiovascular issues. More recently, however, the focus of nitrate supplementation has shifted to focus of human performance, and has shown to increase the time to exhaustion during maximal intensity exercise and lower the cost of oxygen consumption during submaximal intensity exercise. Acutely, nitrate supplementation in the form of beetroot juice has been shown to increase strength measurements, as well as increase the time to complete a 2000 meter rowing ergometer test. However, to the author's knowledge, there are no studies that link the relationship between multi-day nitrate supplementation and the rowing test or the nitrate's effect on strength when in the salt form. Additionally, to the author's knowledge, no evidence has been published which relates dietary nitrate supplementation and its effects on a CrossFit circuit workout. Our central hypothesis is that six days of dietary nitrate supplementation will improve strength, endurance, a power more than a placebo in male CrossFit athletes.
