The component of accuracy in performing a smash is one of the techniques that determine success in the game of volleyball, with the coach playing an important role in providing programs to improve athletes' performance. This study aimed to determine the effect of resistance band and medicine ball training on the accuracy of volleyball smashes, considering the explosiveness of arm muscles in amateur athletes. An experimental method with a 2x2 factorial design and a quantitative approach was used. The subjects were 30 amateur athletes from Yogyakarta State University. Measurement instruments included volleyball smash precision tests and arm muscle explosiveness measurements using the medicine ball throw test. Data analysis was performed using a two-way ANOVA test. The results showed a significant influence of training method on volleyball smash accuracy, with F = 6.116 and p = 0.002. Arm muscle explosiveness also significantly influenced smash accuracy (F = 23.144, p < 0.001). Furthermore, there was an interaction between training method and arm muscle explosiveness on smash accuracy (F = 7.324, p = 0.003). Thus, both resistance band and medicine ball training were effective in improving volleyball smash accuracy, especially when adjusted to the explosive power characteristics of athletes' arm muscles. This study provides recommendations for coaches to consider variations in training methods based on athletes' physical profiles to optimize results.
