title: Effect of isometric and isokinetic muscle training on static strength and dynamic power.
abstract: This study investigated whether isokinetic strength training might induce changes in static and dynamic power already achieved as a result of isometric strength training. The subjects were twelve males. The isometric strength and dynamic power of elbow flexors were tested by means of an electric dynamometer and fly-wheel every two weeks. During the first 8 weeks all subjects trained the elbow flexors isometrically at four different positions of elbow joints. This training produced 27-36% gains in isometric strength and 34-46% in power. Thereafter the subjects were divided into two groups: the FG group who trained isokinetically at a fast velocity of 157 degrees . s-1, and the SG group at slow velocity of 73 degrees . s-1. After 6 weeks of training, the FG group produced a significant gain in power with light equivalent masses and the SG group did so with heavy equivalent masses. Neither group showed change in isometric strength.
