Abstract

Study purpose. This study was conducted in response to insufficient lower leg muscle explosiveness observed in volleyball extracurricular students at State High School 1 Madang Suku III, which adversely affected their jumping performance during gameplay. Materials and methods. A quantitative experimental approach was employed using a two-group pretest–posttest design. Statistical analyses were performed using paired-sample t-tests to examine within-group differences and independent-sample t-tests to compare the effects between groups. Results. The findings revealed that the Jump to Box training method significantly enhanced lower limb muscle explosive power (t = 56.564, p < 0.05). Likewise, the Barrier Hops training method demonstrated a statistically significant improvement (t = 59.088, p < 0.05). However, the results of the independent-sample t-test indicated no statistically significant difference in effectiveness between the two training interventions (p = 0.704). Conclusions. These findings suggest that both Jump to Box and Barrier Hops exercises are equally effective in improving lower limb explosive power among volleyball extracurricular participants.
