Filter by:This study is a randomized, double-blind, placebo-controlled crossover trial examining the effects of caffeinated and non-caffeinated pre-workout supplements on resistance exercise performance. Resistance-trained adults will be randomly assigned to complete three study conditions (caffeinated pre-workout, non-caffeinated pre-workout, and placebo) in one of the six possible condition orders. During each condition, participants will report to the laboratory for ingestion of the assigned beverage and subsequent muscular performance testing. Major performance outcomes will be force production variables from a mechanized squat device and maximal strength and muscular endurance on the bench press and leg press exercises.
The aims of this clinical study are evaluated the effects of Blood Flood Restriction training on the sport performance of professional and semi-professional soccer players. The participants are twenty male professional and semi-professional soccer players who are playing at RCD Mallorca. Participants will be assigned in two different groups. Both groups develop for six weeks a strength training programs. The first group will base their training in Low Load using Blood Flow Restriction (20-50% of one maximum repetition). The second group will base their training in High Load (60-80% of one maximum repetition). This training program includes three type of exercises in each training session; back squat, single deadlift and barbell hip thrust. Before and after this program the investigators will collect sociodemographic and anthropometrics data. On top of that, the investigators will evaluate the muscle mass, the electrical activity produced by skeletal muscles, the muscle strength and the sprint ability of every participant. Before to the evaluation, the soccer players will warm-up during 15 minutes under the control of the evaluators.
To analyze the autonomic behavior in recovery post-acute resistance exercise performed in different intensities and body segments.
Fatigue is one of the most frequently reported and disabling impairments in multiple sclerosis (MS) and is associated with activity limitations, participation restrictions and reduced health-related quality of life (HRQL).MS fatigue is thought to be related to the disease itself, where increased levels of inflammatory biological markers (cytokines) are contributing. Resistance training may have an anti-inflammatory effect where a higher intensity is thought to have a more profound effect. Moderate-intensity resistance training is well tolerated in people with MS (PwMS) and can reduce self-reported fatigue. There is, however, a lack of high-quality studies including only fatigued PwMS when evaluating exercise regimes. Furthermore, the optimal dose (i.e. the combination of duration, frequency and intensity) is not known. Our hypothesis is that high-intensity resistance training will have positive effects in fatigued PwMS on functioning (fatigue, mood, activities and participation) and wellbeing/HRQL; and a positive immunomodulatory effect measured by inflammatory biological markers in blood. Further, that high-intensity resistance training twice a week will be superior to once a week
Knee osteoarthritis (OA) is a rheumatic disease that causes serious cartilage damage in the knee joint. Moderate physical activity can slow cartilage degeneration in moderate OA stages. Remarkable weakness and atrophy of the quadriceps and hamstrings is a common problem in patients with chronic osteoarthritis, but in arthritis, it may be difficult to achieve strength gains due to the pain caused by heavy load-resistant exercises. Exercising with these high loads may not be possible or may injure painful arthritic knees. For this reason, lately, blood flow restriction exercises have been directed to achieve the same gain by exercising with lower loads by restricting the blood flow with a cuff. We aimed to limit the blood flow in osteoarthritic knees and to provide strength gain and pain reduction provided by conventional exercises given routinely. Our hypothesis in this study is that exercises that blood flow restriction exercises will reduce pain and increase strength as well as conventional exercises.
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.
Resistance training (RT) is one of the most important stimuli for muscle hypertrophy and it plays an important role on weight loss and fatty acid oxidation increase. RT affects anabolic pathways but the differences among various training techniques has been till now were poorly investigated. The aim of this study was to compare the effect of two different intensity of training, high-intensity interval resistance training (HIIRT) and traditional resistance training (TRT), on muscle signalling pathway.
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.
The present project aims to investigate the acute and chronic effects of laser photobiomodulation (PBM) at 808 nm on muscle performance in physically active elderly women. The hypothesis of this study is that laser PBM would improve muscle strength (i.e., MVIC and 1RM) and endurance (i.e., repetitions-to-failure, blood lactate levels), functional capacity (i.e., short physical performance battery score), and rating of perceived exertion when compared with placebo laser.
