ISOTONIC TRAINING INCREASES STRENGTH BETTER THAN ISOKINETIC TRAINING

Ss (N = 26) were assigned to a no-training control group, an isotonic training group, or an isokinetic training group. Each was pre- and post-tested on a Cybex isokinetic dynamometer. Both training groups worked twice per week for three weeks. The isotonic group used the
Both exercise groups improved significantly in force, power, and total work in the mode of force in which they were not trained. However, isokinetic training made significantly greater improvements in three of the four measures of flexion of the knees.
Implication. Isotonic exercise is more effective than isokinetic exercise in improving knee flexion strength.
