Improving lower limb muscle power, agility, and aerobic endurance in healthy adolescent boys through plyometric exercises and agility ladder drills

Abstract

This study aimed to enhance leg muscle power, agility, and aerobic endurance in 13-15-year-old boys by integrating plyometric exercises with agility ladder drills. A cohort of 45 participants underwent pretest and post-test assessments, measuring vertical jump performance, agility through the T-Test, and aerobic endurance with the multistage fitness test. Data were analysed using descriptive statistics, the Wilcoxon signed-rank test, and the Mann-Whitney U test. Significantly improved power (P=0.006), agility (p=0.001), and endurance (P=0.001) were observed within the experimental group. Comparing the experimental and control groups revealed notable differences in agility (P=0.000) and endurance (p=0.000), with no significant variance in power (P=0.416). These findings highlight the positive effects of combining plyometric exercises and agility ladder drills on the physical performance of 13-15-year-old boys, recommending this approach for enhancing power, agility, and endurance.
