Adaptive response in human skeletal muscle subjected to prolonged eccentric training.

abstract：:The broad spectrum of skills in sport, with their high demands on strength, speed, endurance, coordination, and flexibility, represents one of the greatest challenges to human motor performances. However, the basic neurophysiological mechanisms in sport are not principally different from those in everyday motor acts. ...
