41 Clinical Trials for Various Conditions
The chronic phase of the study will evaluate the effects of pre-exercise and post-exercise ingestion of a multi-ingredient supplement on adaptations to a 6-week exercise program consisting of both resistance training and high intensity aerobic exercise, using a randomized, double-blind, placebo-controlled design. Participants will complete an enrollment/familiarization visit, a baseline testing session, followed by a 6-week supervised exercise intervention, and post-testing session identical to baseline testing. Participants will be randomized during the baseline session to groups receiving either 1) Active Treatment (pre-post supplementation), 2) placebo (noncaloric beverage), or 3) control, not participating in exercise or consuming a treatment. During the supervised 6-week resistance training program, participants will complete a moderate-intensity warm-up, a full-body resistance training workout (2 x per week) and an interval training session (1 x per week). Thirty-minutes prior to each training session, and within 15 minutes post-exercise, participants will consume their randomly assigned treatment beverage. Body composition, blood markers of muscle damage/recovery, strength, and performance tests will be measured before (baseline) and after training (Post) to evaluate the effects of supplementation. All data collection will be conducted by the Principal Investigator and Research Assistants. All subjects will report to the Applied Physiology Laboratory and Human Performance Center in Fetzer Hall for all testing and training sessions, which will span approximately 8 weeks.
The acute study will evaluate pre- and post-exercise ingestion of a multi-ingredient supplement in a randomized, double-blind, placebo-controlled, crossover design. Participants will complete one enrollment visit, in which they will sign a consent form and complete a health history questionnaire. Participants will complete two interventions, with three visits each (6 visits total), in which a treatment beverage (pre/post supplement, or non-caloric placebo) will be consumed within 30 minutes prior to exercise and within 15 minutes post-exercise, in random order. Total time from enrollment to completion will be at least 14 days. Testing visits will be separated by a minimum of 7 days of rest to allow for recovery and washout, based on a half-life of ≤8 hours for all ingredients present in the supplement.
The purpose of this study will be to test whether a new way of weight training is more effective than typical weight training. The investigators expect that this new way will cause more exercise-induced muscle damage, which helps people build bigger muscles. Another purpose of this study will be to explore perceptions of how muscle soreness impacts participant activities of daily living.
This study is a double-blind, randomized, placebo-controlled, crossover clinical trial of N=40 recreationally active men to be recruited a single investigational center in Ohio (i.e., The Center for Applied Health Sciences). Subjects will take a daily protein supplement (e.g., 15 g of pea protein or 15 g of pea protein + probiotic blend) for 4 weeks, have a 1-week washout period (i.e. meaning they will not take either supplement), and then take the alternate protein supplement for an additional 4 weeks. Outcome variables include plasma amino acids, muscle damage, muscle recovery, and GI tolerance.
Intense exercise can bring about various side effects to one's body. Less range of motion, increased pain sensitivity, increased muscle swelling, and decreased muscle strength can occur immediately after exercise. These side effects can be referred to exercise induced muscle damage (EIMD) and can sometimes last many days. This study's goal is to evaluate the effects of various protein supplements on EIMD symptoms as well as on blood vessel health during the recovery period after muscle damaging exercise.
The purpose of this study is to measure the effect of using a turmeric-based supplement for 2-weeks on muscle damage and soreness that occur in the body after 90-minutes of exercise. Participants will first come to the human performance lab (HPL) for orientation and pre-study fitness tests including muscular fitness and body composition. Participants will be randomized to turmeric or placebo groups, and take 2 tablets of the supplements each day for the first two weeks. Participants will report back to the HPL on a Monday to engage in weight lifting and calisthenics for 90 minutes. Fitness tests (vertical jump, bench press, leg-back lift for strength, 30-second cycling sprint test) and blood samples will be given and collected before and after this exercise session. Participants will then come back to the HPL each morning, Tuesday through Friday, in the early morning to provide blood samples and retake the fitness tests. This study will entail seven HPL visits over a 3-week period.

A retrospective, observational study conducted on cancer patients receiving a drug that blocks certain proteins made by some types of immune system cells
The purpose of this study is to determine if supplementation with NUTRALYS pea protein isolate compared to whey protein and apple juice (carbohydrate, non-protein control) before, during, and after a 90-minute bout of eccentric exercise can attenuate exercise-induced muscle damage, inflammation, and delayed onset of muscle soreness (DOMS), and speed recovery of muscle function.
This is a randomized, repeated measures and double blind study which measures the effect of fenugreek extract on markers of muscle damage and inflammation in non-resistance trained males. Participants will complete baseline testing and then be randomized into groups. Participants will complete a 2 week, split-body resistance training program. They will then return for testing in which they will complete an overreaching protocol for 5 consecutive days. Measurements will be recorded 24 hrs after the fifth day. Participants will resume the training program for one additional week and return for final measurements.
Peripheral artery disease (PAD) is a manifestation of atherosclerosis that produces progressive narrowing and occlusion of the arteries supplying the lower extremities. The most common clinical manifestation of PAD is claudication, i.e., a severe functional limitation identified as gait dysfunction and walking-induced leg muscle pain relieved by rest. The standard therapies for claudication include the medications cilostazol and pentoxifylline, supervised exercise therapy and operative revascularization. Recent data demonstrated that 24 weeks of treatment with the angiotensin-converting enzyme (ACE) inhibitor Ramipril produces improvements in the walking performance of patients with claudication that are higher than those of cilostazol and pentoxifylline and similar to those produced by supervised exercise therapy and operative revascularization. The mechanisms by which Ramipril therapy produces this impressive improvement in the functional capacity of claudicating patients remain unknown. The Investigators hypothesize that treatment of claudicating PAD patients with Ramipril will improve walking performance and quality of life by improving the myopathy of the gastrocnemius. Improved myopathy is a consequence of reduced oxidative damage, reduced TGF-β1 production by vascular smooth muscle cells and reduced collagen deposition in the affected gastrocnemius.
To determine the effect of probiotic supplementation on the inflammatory response and subsequent performance following a muscle damaging exercise bout, a double-blind, randomized placebo controlled two-factor repeated measures design will be employed. The dependent variables for this study will include measures of performance as well as markers of inflammation in a single limb model. Participants who qualify for study participation will have their height, weight, and body composition assessed (skin fold) followed by baseline measurements for determination of isometric and dynamic strength. Initial limb will be determined randomly. Following baseline testing, participants will randomly be assigned to ingest either a probiotic or placebo. Supplementation will begin at least 24 hours post baseline testing. Twenty-one days after initiating supplementation, participants will again complete performance testing followed by an exercise bout known to elicit muscle damage and produce an inflammatory response. Participants will then repeat performance testing 24, 48, and 72 hours post muscle damaging bout. Blood samples for determination of markers of inflammation will be taken throughout study duration. Following a 3-week wash-out period (21 days), participants will repeat the experiment following the alternate supplement regimen with the contralateral limb.
As per non-clinical studies, prolyl hydroxylase inhibitor GSK1278863 can protect muscle from unaccustomed exercise induced muscle damage and enhance functional muscle repair. This study is designed to investigate arm function, pain and other pharmacodynamic (PD) markers after unaccustomed maximal eccentric exercise with concurrent administration of GSK1278863 or placebo. Primary objective of the study is to evaluate the protective effects of GSK1278863 on eccentric exercise induced muscle injury. Subjects will be randomized in a 1:1 ratio (1 subject on GSK1278863 for every 1 subject on placebo). Each subject will be given five oral doses of GSK1278863/placebo in total. The first dose will be administered immediately after completion of eccentric exercise and then 4, 8, 24, and 48 hours later. Subjects will be housed till day 4 in unit and will return for a follow-up visit 7-10 days after discharge. After enrolment of approximately 30 subjects, enrolment will be paused and planned interim analysis will be performed to decide whether to terminate enrolment/study, continue dosing or to reduce the dose to 5 milligrams (mg).
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).
Hypothesis: Six weeks of supplementation with vitamin D (4000 IU/day) using Dole's Vitamin D Portobello Mushroom Powder will increase winter serum vitamin D levels, and improve muscle function and strength, and innate immunity (granulocyte/monocyte phagocytosis and oxidative burst activity), and attenuate exercise-induced muscle damage and DOMS.
Study Objectives 1. Compare beta-hydroxy-beta-methylbutyrate free acid (HMB-FA) to cold water immersion on performance recovery from an acute bout of high intensity resistance exercise. 2. Compare HMB-FA + Cold water immersion to HMB-FA or cold water immersion. 3. Examine the effect of these recovery modalities on markers of muscle damage, inflammation and immune function. Subjects Subjects (men and women, 18 - 35 y) with at least one year of resistance training experience will be recruited. Subjects will be randomly divided into one of four groups: a cold water immersion group (CW), HMB-FA, CW+HMB-FA and a control group (CT). Study Protocol Subjects will report to the Human Performance Laboratory (HPL) on four separate occasions. On the first visit (T1) subjects will be tested for maximal strength \[one repetition-maximum (1-RM)\] on the squat, dead lift and barbell lunge exercises.\] On their second visit (T2) subjects will perform a lower body resistance exercise session consisting of four sets of the squat, dead lift and barbell lunge exercises. All subjects will then report back to the HPL at 24- (T3) and 48-hours (T4) post-exercise. During T3 and T4, subjects will perform four sets of the squat exercise only using the same loading pattern and rest interval length as T2. Following the T2 and T3 workouts subjects in CT will undergo no treatment; subjects in CW will be required to sit in a whirlpool tub for 10-min up to their umbilicus in water at 50° F - 54° F (10° C - 12° C); subjects in HMB-FA will be provided the supplement 30 min prior each workout and CW+HMB-FA will be administered together at time points describe above. Statistical Analysis Statistical evaluation of performance and biochemical changes will be accomplished using a repeated measures analysis of variance (ANOVA).
The purpose of this study is to assess the effects of tart cherry juice to reduce serum biomarkers of inflammation and reduce muscle soreness in healthy adults who undergo a bout of controlled eccentric exercise.
To investigate the effect of Vicia faba protein concentrate, a protein derived from Fava bean extract, on delayed onset muscle soreness (DOMS). Participants receive either 2.4g/day of PeptiStrong® supplement capsules or placebo capsules for 14 days until a strenuous exercise session. For the last 3 days, 2/3 of them stay on the same treatment and 1/3 of them switch from placebo to PeptiStrong®.
The goal of this clinical trial is to investigate the effect of the BTL-899M device on muscular system function in adult subjects seeking treatment for improving their muscular system function in the lower extremities.

Researchers will compare a sham group to see if the device is effective. Participants will complete four treatment visits and two follow-up visits. Their strength will be recorded via a dynamometer.
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.

This study proposal seeks to examine the efficacy of probiotic supplementation at mitigating changes in immune function and recovery after completion of intense, stressful exercise while also allowing for a better understanding of its ability to promote recovery and maintenance of physical performance.
This study investigated the effects of CarnipureTM, a high-quality L-carnitine ingredient, on long term (5 weeks) recovery, muscle damage, and SOD status in a population of males and females while training two days per week. The primary outcomes defining recovery were changes in serum creatine kinase levels and perceptual changes in recovery. Supporting variables included an assessment of strength and power as a functional indicator of recovery. This study would be the first to examine the effects of CarnipureTM on long-term recovery. Our primary hypothesis was that L-carnitine supplementation would reduce muscle damage and improve perceptual measures of recovery. Our secondary hypotheses were that L-carnitine supplementation would better sustain strength and power and elevate SOD status.
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).
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.
