Relationship of Selected Tests of Leg Strength and Leg Power on College Men

Thirty-eight male university students served as Ss. They were tested for leg power using seven tests and for leg strength by means of cable tensiometer methods. The power tests were the vertical jump, standing broad jump, chalk board jump, 5-yd. sprint, 10-yd. sprint, running 5-yd. sprint, and a criterion power score consisting of a vertical jump task performed on a force platform. The leg strength tests were hip extension, knee extension, and ankle plantar flexion with scores recorded for both the dominant and nondominant legs. Data were treated by the product-moment, multiple correlation, canonical correlation, and factor analysis techniques. All the computed correlations were low to moderate suggesting that the contribution of strength to power is minor and that power is a more complex entity.
