Abstract
Introduction. Ideal body weight is an important component for volleyball players, as it is necessary to maintain physical performance during training and matches to maximize effectiveness. The aim of this research was to evaluate the effectiveness of weight training machine and body weight training methods in reducing body fat levels.
Method. This study employed a two-groups pretest-posttest design. The population consisted of female volleyball athletes, with a sample of 14 athletes selected through proportional sampling based on the criteria of female gender, age range between 15–20 years, and possessing the ideal body weight for volleyball players. Ordinal pairing was conducted to divide the participants into groups. The instrument used was a skinfold caliper to measure body fat at the biceps, triceps, subscapular, and suprailiac sites. Data were analyzed using a paired t-test and an independent t-test.
Results.
– The weight training machine group demonstrated a significant reduction in body fat levels, with a calculated t-value of 14.789 and a significance value of 0.000 (< 0.05).
– The body weight training group also showed a significant reduction, with a calculated t-value of 9.348 and a significance value of 0.000 (< 0.05), although the reduction was smaller compared to the weight training machine group.
– A significant difference between the two training methods was observed, with a calculated t-value of -4.583 and a significance value of 0.000 (< 0.05), indicating that weight training machines were more effective than body weight training.
Conclusion. It can be concluded that weight training machines are more appropriate when approaching competition periods to maintain body proportions and optimize performance. Body weight training, however, is more suitable for pre-competition phases or longer training periods.
