PENGARUH LATIHAN PLYOMETRIC TERHADAP PENINGKATAN AGILITY JUMPING SMASH PERMAINAN BULUTANGKIS PADA PEMAIN PB DUA PUTRA SALTIM

Abstract

coordination, balance, and reaction speed to support an effective jumping smash. This study aimed to determine the effect of plyometric training on the agility jumping smash performance of PB Dua Putra Saltim players. The study employed a quantitative experimental approach using a one-group pretest-posttest design. Fifteen active players were selected purposively and completed a 12-session plyometric training program consisting of squat jumps, lateral jumps, hurdle jumps, box jumps, and plyometric-smash drills with progressive volume and recovery. Agility jumping smash performance was assessed through footwork speed, vertical jumping ability, and smash accuracy and power. Descriptive analysis showed that the mean score increased from 71.67 in the pretest to 85.33 in the posttest, an average improvement of 13.67 points. The minimum score increased from 58 to 75, while the maximum score increased from 92 to 100. The paired-samples t-test produced t(14) = -12.696 with p < 0.001, indicating a statistically significant difference between pretest and posttest scores. These findings indicate that structured plyometric training can improve physical components that support jumping smash execution, particularly lower-limb explosive power, agility, coordination, balance, and reaction speed. Plyometric training can therefore be considered a practical training strategy for improving badminton players' agility jumping smash performance.
