最大速度单腿桥测试用于集中功能评估和运动在一个运动员与经常性腿筋应变损伤的运动员:一个案例报告

As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
