Abstract

The purpose of this study was to identify the effect of three different training methods for increasing power output of the leg extension chain. Therefore three groups had to go through an eight week training program. One of the three groups had to perform counter movement jumps (CMJ) twice a week (group J) while the second group had to do two sessions with parallel squats every week. The third group (J + S) had to do the CMJs as well as the parallel squats twice a week. After the training period SJ and CMJ significantly increased in all experimental groups. No significant changes were found in the control group. Group J received an 8,8% increase in the SJ and an 8,9% increase in the CMJ while group S was able to enhance their jumping performance by 12,6% (SJ) and 11,8% (CMJ). Group J + S showed the biggest improvement by 15,5% in the SJ and 14,7% in the CMJ. The only significant difference between the three groups was found between group J and J + S in both testing conditions.
