Exertional Rhabdomyolysis
Exertional rhabdomyolysis (ER) is the breakdown of muscle from extreme physical exertion. It is one of many types of rhabdomyolysis that can occur, and because of this, the exact prevalence and incidence are unclear. Cause ER is more likely to occur when strenuous exercise is performed under high temperatures and humidity. Poor hydration levels before, during, and after strenuous bouts of exercise have also been reported to lead to ER.Clarkson, Priscilla M. "Exertional Rhabdomyolysis and Acute Renal Failure in Marathon Runners." Sports Medicine 37.4 (2007): 361-63. Print. This condition and its signs and symptoms are not well known amongst the sport and fitness community and because of this it is believed that the incidence is greater but highly underreported. Risks that lead to ER include exercise in hot and humid conditions, improper hydration, inadequate recovery between bouts of exercise, intense physical training, and inadequate fitness levels for beginning high-intensity wo ...

Muscle
Skeletal muscles (commonly referred to as muscles) are organs of the vertebrate muscular system and typically are attached by tendons to bones of a skeleton. The muscle cells of skeletal muscles are much longer than in the other types of muscle tissue, and are often known as muscle fibers. The muscle tissue of a skeletal muscle is striated – having a striped appearance due to the arrangement of the sarcomeres. Skeletal muscles are voluntary muscles under the control of the somatic nervous system. The other types of muscle are cardiac muscle which is also striated and smooth muscle which is non-striated; both of these types of muscle tissue are classified as involuntary, or, under the control of the autonomic nervous system. A skeletal muscle contains multiple fascicles – bundles of muscle fibers. Each individual fiber, and each muscle is surrounded by a type of connective tissue layer of fascia. Muscle fibers are formed from the fusion of developmental myoblasts in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
