Filter by:The influence of music on movement velocity and power during strength training have been poorly investigated, and specifically in women there is no evidence of an increase in strength performance due to the influence of music. Hypothesis: Listening to trap or reggaeton music will improve jumping ability, as well as movement velocity and power, muscular endurance, motivation and perception of effort in trained women during the performance of back-squats.
Blood flow restricted (BFR) resistance exercise has been shown to improve skeletal muscle adaptations to low load resistance exercise. One of many adaptations with resistance training is neural adaptations that occur within the first few weeks of resistance training. It has been hypothesized that these neural adaptations are blunted when using blood flow restricted exercise. Therefore, the investigators propose to examine the muscle activation created by resistance exercise with different intensities with blood flow restriction and without blood flow restriction in sedentary compared to resistance-trained individuals. The investigators will recruit and completely study up to 30, previously untrained and resistance-trained, healthy, college-aged (18-40 years) males. Participants will come in the laboratory for 5 total visits. These visits will consist of a screening/familiarization visit, a strength testing visit, and 3 acute exercise visits. The acute exercise visits will consist of 2 blood flow restricted resistance sessions at different intensities and a traditional high load resistance exercise session. The 3 acute exercise visits will be randomized. The investigators will measure muscle mass (appendicular lean mass) using Dual Energy X-Ray Absorptiometry, muscle strength and endurance using isotonic and isokinetic testing, and muscle activation using surface electromyography. The investigators will also use near infrared spectroscopy (NIRS) to measure the muscle tissue (oxygen) saturation index (TSI) in the vastus lateralis during exercise. Finally, the investigators will also draw blood before and after each exercise session to measure hormones, metabolites, and markers of inflammation using commercially available assays (e.g., ELISAs).
The aim of the study will be to evaluate the effect of oral messages on wrist and finger flexor muscle activity during the application of sham therapy in the form of paper plaster. For years, research has been conducted on the effects of dynamic plaster and rigid plaster on muscle function. In many cases, reports from different authors are contradictory. Therefore, the planned study will use placebo paper plaster with no proven therapeutic effect.
The investigators aim to investigate the effect of menstrual cessation in women with endometriosis treated with GnRH analogs for 6 months on bone mineral density and bone and muscle metabolism parameters and subsequently the effects of menstrual restoration after GnRH analogs discontinuation on the above measured parameters
The aim of this study is to estimate tonic vibration latency and whole body vibration reflex latency
It is estimated that about 30% of women cannot voluntarily contract the pelvic floor muscles (PFM). PFM training (PFMT) represents the first therapeutic option for the treatment of female urinary incontinence (UI), however the inability to contract this muscle makes PFMT unfeasible. The primary objective of this project is to evaluate clinically the efficacy of intravaginal electrical stimulation associated with verbal instructions to provide the ability of women to contract voluntary their PFM. The secondary objective is to evaluate the UI prevalence and impact on quality of life.
The purpose of this study are to compare angles of hip joint between before and after releasing quadratus lumborum muscle.
Mobility training in the form of stretching and flexibility training of our skeletal muscle is a common exercise. However, the evidence are scare and there are only a few studies comparing the effect of prolonged static stretching (> 90 sec) and dynamic flexibility training as to which of these methods has the best length-enhancing effect over time. Further, in clinical practice concerning low back pain, the possibility of a thigh hamstrings muscles to affect movement control of the spine is often mentioned, a link not fully explored in a controlled condition. The purpose of this study is to compare the effect of eight weeks of dynamic flexibility training versus prolonged static stretching on mobility in the hamstring muscles in adults with reduced mobility in the muscles at the back of the thigh. The aim is also to compare the sustained effect of flexibility training between the two groups, eight weeks after completion of the intervention. Furthermore, the aim is to explore how different forms of flexibility training affects movement patterns of the lumbar spine in adult persons with reduced mobility in the hamstrings.
This study will investigate the effects of a soy/dairy protein blend on muscle growth and strength. In sports nutrition and in aging it is important to have healthy muscles. This can be achieved with exercise and nutrition. Consumption of protein following resistance exercise can promote healthy muscle growth and help improve strength. Young healthy men will be studied during a 12 week resistance exercise training program and be given protein supplements every day during the study. The hypothesis is that a blend of soy, whey and casein will induce a greater muscle gain and strength increase than the control.
Rationale: Proteins released from muscle during and shortly after exercise, often referred to as myokines, may be central to our understanding of the cross-talk during and after exercise between skeletal muscles and other organs, in particular the liver. So far only a few myokines are identified (e.g. IL-6, IL-8, IL-15, TNF-alpha). Taking into account the role of these several known myokines in developing insulin resistance, revealing new putative myokines might provide valuable information and a direction for future research on the pathogenesis and treatment of type 2 diabetes mellitus. Objective: The objective of the present study is to identify novel myokines, expression of which is altered in skeletal muscle after a single bout of exercise. Study design: experimental study. Study population: Ten healthy, male subjects between 40 and 60 years of age and BMI < 30 kg/m2, will participate in this study. Intervention: A single exercise bout that consists of one hour one-legged cycling on a adapted recumbent cycle ergometer at a submaximal rate. The non-exercising leg will serve as control for the exercising leg. Main study outcomes: Main study outcomes include upregulation of genes in skeletal muscle after exercise (with a focus on genes encoding myokines) and changes of blood plasma levels of selected proteins after exercise.
