Abstract

This study investigated the influence of the jump smash technique (with and without approach) on the accuracy and kinematic parameters of volleyball players' movements, utilizing two-dimensional video analysis (Kinovea) on 12 club members. The kinematic analysis results showed significant differences in three key variables: jump height, external shoulder rotation, and backward trunk lean, where the jump smash technique with approach demonstrated superior values. Although the accuracy data indicated a higher average for the technique without approach (3.85 vs. 3.02), the study concluded that the jump smash technique with approach provided a more significant overall impact on both accuracy and changes in kinematic parameters in the players.volleyball club, when compared to the jump smash technique without a run-up.

Abstract

Aerobic exercise is a structured physical activity with great potential to enhance students' fitness and well-being. This study aimed to examine the effects of an aerobic exercise program on physical fitness, body composition, and sleep quality among students of Universitas PGRI Mahadewa Indonesia. A quasi-experimental design with a pretest-posttest control group was employed. Seventy-two second-semester female students were selected through purposive sampling and randomly assigned to an experimental group (n=36) participating in a moderate-intensity aerobic exercise program for 10 weeks (3 sessions/week, 60 minutes/session), and a control group (n=36) receiving no additional treatment. Physical fitness was assessed using the modified Indonesian Physical Fitness Test (TKJI) and VO₂max (Rockport Walking Test); body composition was measured via bioelectrical impedance analysis (BIA); sleep quality was evaluated using the Indonesian version of the Pittsburgh Sleep Quality Index (PSQI). Data were analyzed using paired t-test, independent t-test, and ANCOVA at α=0.05. Results demonstrated significant improvements in VO₂max (p=0.000; Δ=4.31 mL/kg/min), reduction in body fat percentage (p=0.000; Δ=-2.87%), increase in muscle mass (p=0.002; Δ=+1.24 kg), and improvement in PSQI scores (p=0.000; Δ=-2.6 points) in the experimental group compared to controls. It is concluded that a structured 10-week aerobic exercise program significantly improves physical fitness, body composition, and sleep quality of female students at UPMI. These findings support integrating aerobic exercise as a mandatory component in college student wellness programs.
