ABSTRACT
Aim: Resistance training is the most famous method for the prevention, rehabilitation of myotendinous injuries and especially for the development of muscle’s ability in competitive and recreational sports. The purpose of the present study was to examine the average exerted force ( ), the mean power consumption (Pmean) and the work production on Quadriceps Femoris Muscle of elite athletes, in accordance with joint’s knee movement velocity, during eccentric contractions, before and after the application of a specific resistance training program. Methods: 14 elite athletes participated in this study. Seven of them (training group) performed isometric and eccentric contractions on isokinetic dynamometer before and after the application of specific resistance training program. The other seven athletes (control group) followed the training program of their team and they have participated only to the procedure of measurements. Results: The results showed, that after the application of the specific training program, the subjects improved significantly (P
