The effect of complex training potantiaton on reactive force index parameters

The aim of this study was to investigate the potentiation effect of complex training method on jump height and reactive strength index. For this purpose, 10 recreational active males (Age:25 ± 2.53 years, Height: 186.81 ± 8.46 cm, Weight:84.68 ± 8.02 kg) who has 2 year strength training experience and lifts half squat with at least 1.5 times more than their bodyweight. Participants came twice to the labaratory with 48 hours apart. Anthropometrics measurments, 1RM half squat weight and optimal drop heights were determined during the first session. In the second session participants have applied the complex training method with 3 sets 90% 1-RM half squat and 5 vertical jumps. 15 sec later of the end of the last set the drop jump tests were began. The tests were continued at 2nd, 4th, 8th, 12th and 16th minutes after the third set of complex training protocol. Jump heights, ground contact times and reactive strenght index scores recorded for analysis. It was understood that parametric assumptions of the data obtained were fulfilled (p> 0.05). According this finding repeated measures ANOVA test was used to determine the differences of testing times of each parameter. The confidence interval was accepted as 0.05 in this study. As a result of the study, there is a statistically significant difference between the potentiation effect of the complex training and the jump height at the 4th measurement minute (p <0.05). The significance was also seen with the ground contact time in 15th seconds (p<0.05). The significant differences between reactive strength index testing times was at 15th seconds, 2nd, 4th, 12th and 16th minutes (p <0.05). As result of this study, it was observed that complex training potentiation did not have a positive effect on reactive strength index parameters.
