Exercise-associated muscle cramps : ウィキペディア英語版 | Exercise-associated muscle cramps Exercise-associated muscle cramps (EAMC) are defined as cramping (painful muscle spasms) during or immediately following exercise. Muscle cramps during exercise are very common, even in elite athletes. EAMC are a common condition that occurs during or after exercise, often during endurance events such as a triathlon or marathon.〔〔 Although EAMC are extremely common among athletes, the cause is still not fully understood because muscle cramping can occur as a result of many underlying conditions. Elite athletes experience cramping due to paces at higher intensities.〔〔 The cause of exercise-associated muscle cramps is hypothesized to be due to altered neuromuscular control, dehydration, or electrolyte depletion.〔〔〔 == Electrolyte depletion and dehydration theory ==
It is widely believed that excessive sweating due to strenuous exercise can lead to muscle cramps. Deficiency of sodium and other electrolytes may lead to contracted interstitial fluid compartments, which may exacerbate the muscle cramping. According to this theory, the increased blood plasma osmolality from sweating sodium losses causes a fluid shift from the interstitial space to the intervascular space, which causes the interstitial fluid compartment to deform and contributes to muscle hyperexcitability and risk of spontaneous muscle activity.〔〔
