THE EFFECT OF LOADED VERSUS UNLOADED PLYOMETRIC TRAINING WITH CHANGE OF DIRECTION ON PHYSICAL FITNESS PERFORMANCE IN MALE FOOTBALL PLAYERS
Main Article Content
Abstract
Purpose
This study aims to investigate and compare the effects of loaded and unloaded plyometric training with change of direction on physical fitness performance in male football players.
Methods
Twenty-six male football players (aged 18-25 years) were randomly divided into two groups of 13 based on matched pairs of relative strength. The experimental group (EG) performed loaded plyometric training with change of direction, using a weighted vest equating to 8% of their body weight, while the control group (CG) performed unloaded plyometric training with change of direction. Both groups completed training session twice a week for 8 weeks. Assessments of strength, speed, muscular power, agility and aerobic capacity were conducted before training, 4 weeks, and 8 weeks after training. Data was analyzed using one-way repeated measures ANOVA within groups, with Bonferroni adjustment for pairwise comparisons, and independent sample t-tests for between groups at the significant level of p < 0.05.
Results
The results showed that the EG showed significantly greater improvements in physical fitness performance compared to CG (p < 0.05) after 8 weeks of training. Moreover, within group comparison, after 8 weeks, the EG and CG showed significant improvements in physical fitness performance compared to the baseline and after 4 weeks. (p < 0.05).
Conclusion
Loaded plyometric training with change of direction is more effective in enhancing physical fitness performance. Therefore, incorporating loaded plyometric training with change of direction is recommended for improving the physical performance of male football players.
