COMPARISON BETWEEN PLYOMETRIC AND ISOKINETIC TRAINING DURING THREE WEEKS ON ISOKINETIC STRENGTH IN SPORT SCIENCES STUDENTS

##article.abstract##

The purpose of the present study was to compare the effects of 3 weeks of isokinetic training vs plyometric training of the knee flexors and extensors on isokinetic strength. Twenty four students volunteered to participate, divided into 3 groups: one group performed the isokinetic exercises; a second group performed consecutive jumps, and a third was a control group. The knee extensor and flexor muscle peak torque, total work and average power of each leg were concentrically measured at 300º·s-1 using a Biodex System 3 isokinetic dynamometer. The results indicated that the concentric isokinetic training resulted in increase peak torque. ANOVA analysis between the three groups revealed statistical differences for peak torque (p<0.05) and average power (p<0.05) knee extension right leg and peak torque knee extension left leg (p<0.05).
