Abstract

Introduction:The aim of this research is to compare the effects of three training methods — plyometric, weighted, and barbell (Turkish) training — on the anaerobic capacity of high school male volleyball players. A total of 48 subjects, aged 23 ± 5 years, were selected purposefully and randomly divided into four groups of 12 participants each.
Methodology:The height and weight of the participants were recorded, and their anaerobic capacity was measured using the Lewis formula based on the vertical jump test during the pre-test. The three experimental groups performed weight training, plyometric exercises, and plyometric exercises combined with weights, respectively. The fourth group followed a standard volleyball training regimen. The training period lasted eight weeks, with three training sessions per week. After the eight weeks, a post-test was conducted to measure the effects of the different training methods on the participants' anaerobic capacity.
This research was conducted in a semi-experimental design due to the uncontrollability of some factors influencing the independent variable. For data analysis, a t-test was used to evaluate the differences between pre-test and post-test results, and to compare the means between the three experimental groups.
Results:The results of this study showed:Eight weeks of weight training significantly improved the anaerobic capacity of the volleyball players.Eight weeks of plyometric training significantly improved the anaerobic capacity of the volleyball players.Eight weeks of barbell (Turkish) training significantly improved the anaerobic capacity of the volleyball players.There was no significant difference between the effects of the three training methods on anaerobic capacity.
