EFFECTS OF CONCENTRIC TRAINING ON POWER AND CHANGE-OF-DIRECTION SPEED

Main purpose of this study was to determine and analyse effects of concentric training on jumping power and change-of-direction speed. Ninety-seven healthy physically active men participated in this study (age: 20 ± 2 yrs ; body mass 76.1 ± 7.4 kg ; body height 181.3 ± 5.7 cm). Experimental procedure consisted of initial testing, 10 weeks of concentric jumping training and final testing. Motor abilities were measured using seven tests for determining power (4) and change-of-direction speed (3). Experimental group conducted concentric jumping training for 10 weeks, 3 times per week. Control group continued with their regular daily activities. Differences between groups at the beginning and at the end of experiment were determined using discriminative analysis. Main results of this research show that concentric jumping training has a negative influence on change of direction speed. These results imply that in agility training, concentric jumping exercises should not be performed.
