Purpose: 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. Method: 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. 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. Conclusion: Based on the results of this research, it can be concluded that weight training, plyometric training, and barbell training are all effective in increasing the anaerobic capacity of volleyball players. Given the available time, number of athletes, and resources, any of these training methods can be selected to improve the anaerobic power of athletes. Coaches may choose the most appropriate method depending on the specific needs of their athletes and the resources available.
