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.

Abstract

This study aims to analyze the components of the physical condition of students of the Physical Education Study Program, University of PGRI Palembang class of 2024/2025. The research method used is a quantitative descriptive analysis method, with a sampling technique using purposive sampling. The sample in this study amounted to 40 students who met the criteria of being active in college and were willing to take a physical condition test. The data collection technique was carried out through the Indonesian Physical Freshness Test (TKJI) for the age group of 19–25 years which consisted of five test items, namely 60-meter sprint, pull-up, sit-up, vertical jump, and 1200-meter run. The results of the study show that the physical condition of students in general is in the good category. The average test results included 32 times arm muscle strength, abdominal muscle strength 35 times, cardio-pulmonary endurance 2,500 meters, speed 7.0 seconds, agility 10.8 seconds, flexibility 22 cm, and leg muscle explosiveness 48 cm. Based on these results, it can be concluded that Physical Education students of the University of PGRI Palembang class of 2024/2025 have good physical condition, but continuous improvement through a systematic exercise program is still needed to achieve an optimal level of physical fitness.
