76 Clinical Trials for Various Conditions
The purpose of the research is two-fold. One goal is to determine if post-exercise almond or cereal bar consumption can promote muscle gain as well as increasing muscular strength throughout an eight-week weight training program. The other goal is to assess the short-term effects of almonds or cereal bar on recovery that may explain the overall long-term adaptations.
The purpose of this pilot study is to investigate the effect of hyperbaric oxygen treatment on recovery from exercise in high performance athletes. Outcome measures will be both physical outcome measures from a force plate, as well as physiologic measures of recovery (including blood lactate and muscle oxygenation) and perceived rates of exertion and recovery.
This proposal's objective is to investigate the effects of topical cannabidiol (CBD) cream on exercise-induced muscle damage, exercise-induced inflammatory markers, and subsequent exercise performance after an exercise-induced damage protocol.
The PURPOSE of this study is to see if eating almonds for four weeks will reduce muscle damage, soreness, and inflammation during several days of recovery from eccentric exercise.
This study will examine the effects of nutritional supplement on post-exercise muscle soreness as well as recovery of muscle strength and function.
The PURPOSE of this study is to investigate the combined influence of 2-weeks blueberry ingestion and banana ingestion (during exercise) on performance and in mitigating metabolic perturbation, immune dysfunction, and increase in inflammation following a 75-km cycling time trial. We hypothesize that the combination of 2-weeks ingestion of blueberries (versus placebo) and acute ingestion of bananas (versus water alone) during 75-km cycling will: 1. Enhance performance. 2. Attenuate the magnitude of metabolic perturbation due to exercise (using a targeted panel of metabolites) which may be associated with increased plasma levels of beneficial gut-derived phenolics. 3. Attenuate post-exercise inflammation (as measured with cytokines, muscle damage markers, regulatory lipid mediators, ex-vivo monocyte cell cultures, and targeted immune proteins including S100A8 and S100A12). 4. Counter post-exercise downturns in innate immune function (natural killer cell lytic activity), and viral defense (using an ex-vivo cell culture with Hela cells).
Athletes who are participating in the Keys100 Ultramarathon event in Key West, FL are eligible, based on inclusion criteria, to participate in this research study that is seeking to determine whether supplementation of beer (alcohol) immediately following a long distance ultramarathon race can positively impact exercise-associated hyponatremia \[EAH\].
The purpose of this study is to evaluate the dose-dependent effects of glucosyl-hesperidin (CITRAPEAK) supplementation on exercise performance, recovery indicators, blood flow, cognitive function, mood, sleep, and fuel utilization in recreationally active adults.
Oral Melatonin is a commercially available product available alone and as a constituent in a number of supplements. Previous research suggests that short-term supplementation with oral melatonin may amplify the recovery response to damaging resistance exercise via modulation of subsequent immune and inflammatory responses. However the effects of oral melatonin on neutrophil and monocyte invasion/migration, a critical step in the resolution of skeletal muscle tissue homeostasis, has not been examined. An oral melatonin supplement (5mg) will be provided three times daily beginning 24-hours before and ending 48-hours after an acute bout of damaging resistance exercise (total 15mg/day for 3 days). Goals: 1. To investigate the effect of melatonin on systemic and cellular responses following an acute bout of damaging resistance exercise. 2. To investigate the effect of melatonin on measures of functional performance before and during recovery from an acute bout of damaging resistance exercise.
Dehydration lowers both physical and mental performance if it is severe enough. Performance declines are more pronounced in hot conditions or after prolonged strenuous activity such as exercise. Most individuals drink less than their sweat losses during activity, while some individuals overdrink and develop a sodium deficiency. Water and electrolyte balance must be restored as part of the recovery process after any activity that causes sweating. Plain water causes a decrease in plasma sodium concentration and osmolality, which reduces the desire to drink and increases urine production. Unless the volume ingested exceeds the loss, individuals are in net negative fluid balance throughout the recovery period due to urinary losses. When sodium and potassium are added to rehydration fluids, urine production is reduced in the hours following rehydration. Rehydration is only possible if a volume of fluid equal to or greater than the amount lost through sweat is consumed, together with adequate electrolytes. The test products for this study, TP1 and TP2, are novel hydration beverage formulas. They are an electrolyte drink mixture with five essential vitamins and three times more electrolytes than typical sports beverages. The test products create an osmotic force that permits water to be supplied to the bloodstream sooner in the digestive system by using a specific ratio of sodium, glucose, and potassium. This randomized, placebo-controlled, semi-blind, crossover study will evaluate the effects of the test products on rehydration in healthy adults.
The aim of the clinical trial is to evaluate the efficacy of two novel hydration products on rehydration following exercise.
Heart rate variability (HRV) is a measure of the variation in time between each heartbeat. It is an indirect and ubiquitous biomarker of performance readiness and recovery measured by most consumer-grade wearable fitness trackers. However, there is little documented on the relationship between HRV, training load, and performance measures in the Real-World. Whoop wrist-worn activity trackers have been validated against the gold-standard Electrocardiography (ECG) for HRV and HR measurements. Whoop leverages photoplethysmography (PPG) technology to continuously track (HR, HRV, respiratory rate, energy expenditure) and provides, daily, individual insights, trends, and coaching to improve strain, sleep, and recovery. Research has demonstrated that heart rate variability (HRV) guided training may be more optimal compared to predetermined training for aerobic exercise improvements. The purpose of this study is to assess the feasibility of providing personalized training recommendations based on HRV measured by a consumer-grade wearable (Whoop) in a real-world setting to better understand the HRV relationship with performance.
The purpose of this study will be to examine the effects of Oceanix supplementation on isometric mid-thigh pull force kinetics and salivary immunoglobulin A (indice of immune function) following a one-week intense resistance training protocol. The study will be carried out in a randomized, double-blind, placebo-controlled, parallel manner. Subjects will be stratified into quartiles based on peak force achieved in the isometric mid-thigh pull assessment during screen and prior to baseline testing. Subjects from each quartile will be randomly divided by into treatment and or placebo conditions. Following randomization, subjects will be baseline tested on isometric mid-thigh pull and salivary immunoglobulin A. Following baseline testing, subject will be given their respective supplement conditions and will be instructed to consume one serving (25mg) a day for 21 consecutive days. For days 1 through 14 subjects will be asked to refrain from resistance training. Subjects will undergo a five day intense resistance training protocol will on day 15 to day 19. Subjects will complete follow-up testing in a manner identical to baseline on day 20 and 21 (24- and 48-hours post completion of the training protocol).
This study is intended to evaluate the effect of the dietary supplement combination of NEM® brand eggshell membrane + KD PUR® brand fish oil versus placebo in reducing exercise-induced joint pain, stiffness \& cartilage turnover in healthy men \& women. Half of the study participants will receive NEM + fish oil, once daily, orally while the other half of the study participants will receive placebo, once daily, orally while performing an exercise regimen every other day for two weeks.
Kona Deep is bottled water extracted from a depth of 3000 feet off the cost of Kona, Hawaii. Kona Deep claims that this unique source provides water that is "naturally free of pathogens, chemicals and pollutants and rich in nutrients and minerals that are readily absorbed by the body". The investigators wish to examine Kona Deep's claim that this water is "beneficial to the human body" by testing the impact of drinking Kona Deep on exercise performance and recovery. Subjects will be exercised to a safe level of dehydration and then will be rehydrated with Kona Deep water, or commercially available bottled spring water or Gatorade as controls. Subjects will perform a simple exercise to evaluate peak power performance. This measurement will be compared between rehydration methods for significant differences.
There is a lot of research on how to treat people with sport-related concussion. There has not been a lot of research on the treatment of injured workers with concussion. An exercise program has been developed for people with sport-related concussion. It is suspected that this program may be helpful for injured workers with concussion too. This study will test the effect of this exercise in injured workers with concussion.
The objectives of this study are to assess the effectiveness of a nutritional supplement on muscle functional recovery following induced muscle damage from high intensity resistance exercise. The investigators hypothesize that a short-term dietary supplementation will significantly improve muscle functional recovery following an intense bout of eccentric exercise compared to a placebo.
Part one of this study will consist of baseline (BL) testing, 28 days of daily supplementation with XSurge, and an exercise protocol. The acute exercise protocol consists of five visits, of which, the first visit will consist of maximal strength testing. The remaining visits will consist of performance testing and muscle evaluation. Phase two of this study will consist of six weeks of supervised resistance training along with supplementation of XSurge. Following the six weeks of training, subjects will complete a second acute exercise protocol. Measures to be evaluated will consist of performance testing and muscle evaluation.
To examine the effects of once daily supplementation with 500mg VeriSperse® resveratrol (VRES) for 17 days on muscle function, delayed onset muscle soreness, systemic concentrations of muscular damage markers and markers of oxidative stress in resistance trained young adult males following a damaging isoinertial squat protocol (ISP).
The primary objective of this study is to evaluate the influence of elbow position on achieving forearm supination and pronation and wrist ROM postoperatively. It is anticipated the results will show recovery of functional motion in a shorter period of time (27 days average). As for the secondary objective of the study, it is anticipated there will be limited pain and cost-containment. These data elements will serve as secondary factors to evaluate.
The purpose of this randomized controlled trial is to examine whether systematic sub-threshold exercise is effective in improving recovery time in athletes after sport related concussion (SRC) compared to those who participate in a placebo/stretching protocol. subjects will be randomized into either an Exercise group or a Placebo/stretching group. subjects in the Exercise group will participate in an individualized exercise program supervised by their athletic trainer while the Placebo/stretching group will engage in a standardized stretching routine supervised by their athletic trainer throughout the duration of their recovery. Hypothesis 1: subjects in the aerobic Exercise group will require fewer days to recover from SRC than those who follow a placebo/stretching protocol. Hypothesis 2: heart rate threshold (HRt) achieved on the graded treadmill test will be associated with days to recovery (i.e., the lower the HRt, the longer the time to recovery). Hypothesis 3: Vestibular Ocular Motor Screen (VOMS) performance will be indicative of time to clinical recovery from concussion as evidenced by a strong correlation between VOMS score and days to clinical recovery. Hypothesis 4: Sub-threshold aerobic exercise will facilitate improvement in VOMS post-concussion. Hypothesis 5: subjects in the aerobic exercise group will demonstrate greater dynamic stability as evidenced by greater reach in each of the 3 primary directions (anterior, posterior medial and posterior lateral) for their right and left lower extremity.
The primary aim of this study is to determine the effects of pre-surgery exercise known as Prehabilitation, on functional outcomes for patients following Total Knee Arthroplasty (TKA) surgery. The hypothesis is patients that receive effective pre-surgery prehabilitation will demonstrate improved recovery as measured by the 6-minute walk (6MW) test at one month post surgery.
The primary aim of this study is to develop a feasible, acceptable, and effective multilevel physical activity (PA) intervention that addresses both individual and interpersonal factors that can be easily scalable and delivered in the context of a methadone clinic. To do so, the investigators will train methadone maintenance treatment (MMT) patients who are already engaging in PA at public health recommended levels to deliver a group-based PA intervention to physically inactive MMT patients at a large community-based methadone clinic. Through the development of interpersonal relationships and social support, the investigators expect that MMT peers who have successfully navigated challenges associated with PA in this population (i.e. depression, smoking, triggers for drug use in environment) will help physically inactive MMT patients increase self-efficacy and motivation for initiating and sustaining PA.
In a previous study at the Appalachian State University (ASU) Human Performance Laboratory at the North Carolina Research Campus (NCRC), investigators showed that cyclists ingesting about one-half of a banana with water every 15 minutes cycled 75-km faster (5%) than with water alone. The polyphenols (i.e., chemicals in plants with health benefits) in the banana improved the capacity to counter oxidative stress, and the sugars lowered post-exercise inflammation. The cyclists reported some gastrointestinal discomfort, however, from the high volume of bananas consumed. Dole Foods, the sponsor of this study, has a banana collection that includes many different varieties, including the Mini banana that has a higher sugar (50%) and phenolic (63%) content than the typical banana (Cavendish) available in stores. Thus athletes should experience similar performance benefits from a smaller volume of Mini compared to Cavendish bananas, and reduced gastrointestinal symptoms. If study results are favorable, Dole Foods may market the Mini banana as the "sport" banana. The purpose of this study is to compare ingestion of Mini and Cavendish bananas with an equicaloric, sugar-only beverage or water on 75-km cycling performance and post-exercise oxidative capacity and stress, inflammation, immune function, muscle damage and soreness, and gastrointestinal symptoms.
Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure for older adults with severe symptomatic aortic stenosis who are considered high risk for surgical aortic valve replacement. Despite symptomatic and survival benefits, many patients experience functional decline after TAVR. This pilot study aims to test the feasibility of a home-based exercise intervention targeting endurance, strength, and balance as well as cognitive behavioral intervention to improve physical functioning and disability after TAVR.
Intense, eccentric resistance exercise causes muscle damage, soreness, inflammation, and a loss of muscle function. Protein-amino acid supplementation before, during, and following damaging resistance exercise may reduce muscle damage and accelerate recovery. This study will determine if supplementation with Herbalife 24 Rebuild Strength (compared to placebo) before, during, and after a 90-minute bout of eccentric exercise attenuates exercise-induced muscle damage, inflammation, and delayed onset of muscle soreness (DOMS), speeds recovery of muscle function, and maintains immune function in NASCAR pit crew athletes (Hendrick Motor Sports).
The goal of this observational study is to learn how the menstrual cycle affects immune cell activation, recruitment, and recovery responses after resistance exercise in healthy, resistance-trained women aged 18-40. The main questions it aims to answer are: Does the menstrual cycle influence neutrophil recruitment and adhesion after resistance exercise? Does the menstrual cycle affect markers of muscle damage and functional recovery? Researchers will compare three menstrual phases (early follicular, late follicular, and mid-luteal) to see if immune responses and recovery outcomes differ across these phases. Participants will: Complete resistance exercise protocols across three different menstrual cycle phases. Provide blood samples to assess immune cell activation and muscle damage markers. Track sleep, mood, and recovery with questionnaires and wear an accelerometer.
