The purpose of this study was to evaluate the effects of Salvia miltiorrhiza Bge on the shot speed and decuple jump performance of handball players. The subjects for the study were 20 senior high school handball players separated into a treatment group (TG) and a control group (CG) with equal number of players by Purpose Sampling. During the 8 week period of study, both groups underwent routine training, but the TG players were given Salvia miltiorrhiza Bge. The Penalty-throw was used to measure handball shot speed while decuple jump performance was evaluated by the total distance covered. Single factor ANCOVA was used to examine the differences between the groups after training with pretest values as a covariate. The result of this study showed that the TG players had significantly increased both shot speed (74.7±5.76 km/hr vs. 79.2±7 km/hr), and decuple jump distance (24.75±1.52 m vs. 25.26±1.55 m). Findings, shot speed at the end of the 8 weeks showed no statistically significant improvement over that measured after 4 weeks, suggesting that the effect of Salvia miltiorrhiza Bge on shot speed plateaus after 4 weeks while the effects on decuple jumping begin after 4 weeks of use. The Salvia miltiorrhiza Bge could enhance lung capacity besides improving handball player's muscular strength especially upper extremity.
