Repeated sprint and change-of-direction abilities in soccer players: effects of age group.

abstract：:Strength and conditioning training for football has become year-round in virtually all levels of play, but none so much as contemporary NCAA DI football. Football players spend more off-season months and weeks in preparation for sport than is given to in-season practice, let alone play. A present peculiarity to NCAA F...
