The Effect of Drill-Passing Training Through Circuit Training on the Underhand Passing Ability of Volleyball Extracurricular Students at SMP Negeri 5 Prabumulih

Abstrak

Objectives: This study aimed to determine the effect of drill-passing training through circuit training on the underhand passing ability of students participating in the volleyball extracurricular program at SMP Negeri 5 Prabumulih. Materials and Methods: A quantitative pre-experimental method with a one-group pretest–posttest design was used. The participants were 25 male volleyball extracurricular students selected using purposive sampling. The intervention consisted of 16 training meetings conducted from April to May 2026, three times per week, with each session lasting approximately 90 minutes. The training was organized into four circuit stations emphasizing repeated underhand passing drills, technical control, coordination, and movement consistency. Underhand passing ability was measured using the Brady Volleyball Test. Data were analyzed using the Shapiro–Wilk normality test and paired-sample t-test with SPSS version 26. Results: The mean pretest score was 14.56, while the mean posttest score increased to 18.68. The Shapiro–Wilk test showed that both pretest and posttest data were normally distributed (p = 0.447 and p = 0.507). The paired-sample t-test indicated a significant improvement after the intervention, with a mean difference of -4.120, t(24) = -23.375, p < 0.001, and a 95% confidence interval from -4.484 to -3.756. Conclusions: Drill-passing training delivered through circuit training significantly improved students’ underhand passing ability. This method can be recommended as a structured and practical training strategy for volleyball extracurricular programs at the junior secondary school level.
