This study aimed to analyze the simultaneous contribution of leg muscle explosive power and hand-eye coordination to the smashing ability of volleyball extracurricular participants at SMA Negeri 1 Negara. The study employed a correlational method involving 30 male students selected through purposive sampling. Research instruments included a vertical jump test, a target-based ball throwing and catching test, and a smash skill test. Data analysis was conducted using multiple linear regression. The results showed an F-value of 384.58 (Sig. = 0.00 < 0.05) and an R² of 0.97, indicating that leg muscle explosive power and hand-eye coordination simultaneously contributed 97% to the variation in smashing ability, while the remaining 3% was attributed to factors outside the research model. Thus, there is a significant simultaneous contribution of leg muscle explosive power and hand-eye coordination to the volleyball smashing ability of the extracurricular participants at SMA Negeri 1 Negara
