Speed-Specific lsokinetic Training.

The authors studied the effects of high speed (240 degrees /sec) and low speed (60 degrees /sec) isokinetic exercise. Twenty-four subjects were randomly selected into one high speed and one low speed treatment group; treatments consisted of one set of 15 repetitions, 3 times a week for 6 weeks. Pre- and post-testing with a Cybex II isokinetic dynamometer was performed to determine if significant strength gains were elicited at 30, 60, 180, 240, or 300 degrees /sec. Both low and high speed groups produced significant strength gains (0.0 1 significance level) at their treatment speed and at one testing speed higher. However, this study indicates that the range of this carry over is not sufficient enough to replace speed-specific training. J Orthop Sports Phys Ther 1984;6(3):181-183.
