Abstract

Training with an optimal demand maximizing muscle power is recommended and considered superior to classic demand training which lacks precisely determened intensity The first goal of this research was to examine the number of repetitions required to achieve variables of high reliability determining the optimal drop height (DHopt) while using the picking or fitting methods and following variables: relativized maximal muscle power in the concentrated phase of jump (PPcon), achieved jump height (H), and reactive strength index (RSI). The second goal was to examine the correlation between the two methods used and variables that define DHopt Thirty examinees participated in this experiment (students of the Faculty of Sport and Physical Education, University of Belgrade) When DHopt was determined by the variable PPcon using the fitting method (two repetitions were enough) the smallest number of repetition was needed to achieve 'high' reliability. When DHopt was determined by the variable RSI using the picking method three repetitions were needed, and when DHopt was determined by the variable H using the picking and fitting methods five repetitions were needed in order to achieve high reliability The fewest number of repetitions was needed when DHopt was determing PPcon using the picking method The lowest correlation between the methods of picking and fitting, the only statistically significant different DHopt between the two methods, was shown when DHopt was determined by PPcon variable.
