It was found that isotonic training was better than isokinetic training for increasing muscle strength and power, full range of motion strength development, and that increases in power are specific to the mode of training and testing.

Implication. Since isotonic activities better reflect the movements of sport they would seem to be the preferred form of training. That isotonic training also produces specific and full development of the muscle also supports its value over isokinetic training.
