Download or read book Rest Interval Effects on Torque and Muscle Performance During Maximal Isokinetic Exercise written by Daniel Allen Keller and published by . This book was released on 1999 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The use of isokinetic exercise for assessing muscle function has been vastly incorporated in orthopedic and sports medicine. Isokinetic exercise allows major muscle groups to exert maximal force throughout the full range of motion (Perrin, 1993). To date, there is little information on the effects of rest interval length on isokinetic force production. The purpose of this study was to examine the effects of rest interval length on muscle efficiency and force output. The 37 subjects were recreationally active college students with no previous history of injury to the lower extremity, ages 21 to 35. Following a pre-test evaluation (three maximal voluntary contractions), subjects were randomly assigned to one of two groups: Group one performed 4 sets of 30 maximal isokinetic quadrceps contractions on the Biodex Systems II isokinetic dynamometer with a 60-second rest interval between each set. Group two performed the identical exercise protocol as group one with the exception of a five-minute period of rest in between each set. Prior to and following the four sets of isokinetic contractions, the subjects performed three MVC's with the knee at an angle of 60 degrees. Electromyography (EMG) will be used to assess muscle fatigue within the two rest interval groups. A two-minute period of rest is taken in between each isometric contraction. Peak quadriceps torque decreased regardless of the rest interval (F = 70.6, p = 0.01). IEMG amplitude did not change following fatigue in the vastus lateralis and rectus femoris. However, data indicated a significant test effect in EMG mean frequency with the vastus lateralis (F = 41.34, p = 0.01) and rectus femoris (F = 79.35, p = 0.01) and group (F = 10.48, p = 0.03) effect. Such findings in EMG reveal a fatiguing effect upon the quadriceps muscles"--Document.

Available in PDF, EPUB and Kindle. Book excerpt: This volume describes the current state of our knowledge on the neurobiology of muscle fatigue, with consideration also given to selected integrative cardiorespiratory mechanisms. Our charge to the authors of the various chapters was twofold: to provide a systematic review of the topic that could serve as a balanced reference text for practicing health-care professionals, teaching faculty, and pre-and postdoctoral trainees in the biomedi cal sciences; and to stimulate further experimental and theoretical work on neurobiology. Key issues are addressed in nine interrelated areas: fatigue of single muscle fibers, fatigue at the neuromuscular junction, fatigue of single motor units, metabolic fatigue studied with nuclear magnetic resonance, fatigue of the segmental motor system, fatigue involving suprasegmental mechanisms, the task dependency of fatigue mechanisms, integrative (largely cardiorespiratory) systems issues, and fatigue of adapted systems (due to aging, under-and overuse, and pathophysiology). The product is a volume that provides compre of processes that operate from the forebrain to the contractile proteins.

Download or read book Fitness Measures and Health Outcomes in Youth written by Institute of Medicine and published by National Academies Press. This book was released on 2012-12-10 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical fitness affects our ability to function and be active. At poor levels, it is associated with such health outcomes as diabetes and cardiovascular disease. Physical fitness testing in American youth was established on a large scale in the 1950s with an early focus on performance-related fitness that gradually gave way to an emphasis on health-related fitness. Using appropriately selected measures to collected fitness data in youth will advance our understanding of how fitness among youth translates into better health. In Fitness Measures and Health Outcomes in Youth, the IOM assesses the relationship between youth fitness test items and health outcomes, recommends the best fitness test items, provides guidance for interpreting fitness scores, and provides an agenda for needed research. The report concludes that selected cardiorespiratory endurance, musculoskeletal fitness, and body composition measures should be in fitness surveys and in schools. Collecting fitness data nationally and in schools helps with setting and achieving fitness goals and priorities for public health at an individual and national level.
