Abstract
The objective of this study was to examine the influence of isokinetic training and low-frequency electrostimulation in three groups of male athletes (N=20, each group). Three different training methods have been compared: isokinetic training (IT) alone, training with low-frequency electrostimulation (LEFS), and the combination of the two methods. Maximal muscle power was measured before and at the end of the training programs, using a REV 9000 isokinetic dynamometer. The findings indicate that all training methods result in significant increase in muscle strength. However, the largest training effect was due to the combination of IT and LFES.
