Abstract

This study examined the effect of a plyometric training program on the leg power of track and field athletes at Yating National High School during the School Year 2025–2026. It focused on three key components of performance: speed, agility, and power. A true experimental design, specifically the pretest–posttest control group design, was used in the study. Sixty (60) student-athletes were selected through purposive sampling and then randomly assigned to either the control or experimental group. The experimental group participated in a four-week plyometric training program conducted three times a week, while the control group continued with their regular training routine. Performance was measured using the 40-meter sprint test for speed, the Illinois agility test for agility, and the standing long jump test for power. The collected data were analyzed using mean and standard deviation, as well as paired sample t-test and independent sample t-test at the 0.05 level of significance. The results showed that both groups improved after the training period; however, the experimental group showed greater improvement across all variables. No significant difference was found between the two groups during the pretest, indicating that they had similar starting levels. Significant improvements were observed from pretest to posttest in both groups. When comparing the posttest results, significant differences were found in speed and agility, while no significant difference was noted in power.

Keywords: Plyometric training, athletic performance, track and field athletes.
