Abstract

This study aimed to determine the effect of resistance band overhead press training on the arm muscle strength of students participating in the volleyball extracurricular program at SMP Kartika IV-1 Surabaya. A quantitative approach was employed using an experimental method and a One-Group Pretest–Posttest design. The study involved 20 students selected via total sampling. Arm muscle strength was measured using a push-up test, while the intervention consisted of resistance band overhead press training administered over six weeks with a frequency of two sessions per week. Data analysis was performed using IBM SPSS Statistics version 25. A Shapiro Wilk normality test indicated that the pretest and posttest data were normally distributed. Hypothesis testing using a paired-sample t-test revealed a significant difference in arm muscle strength scores before and after the training (t = −17.253, df = 19, p < 0.001). The results indicate that resistance band overhead press training can serve as an effective method for improving the arm muscle strength of students in the volleyball extracurricular program.
