This study aims to find out: (1) the difference in influence between plyometric exercises side-to-side box shuffle and box jump on limb power; (b) differences in the influence of players who have high and low leg muscle strength against limb power; and (c) the interaction between plyometric exercises side-to-side box shuffle and box jump and limb muscle strength to leg power in wrestling athletes. This type of research is an experiment using a 2 x 2 factorial design. The population in this study was a South Coastal District wrestling athletes who numbered 38 people. The sample in this study amounted to 20 people who were taken using purposive sampling techniques, then performed ordinal pairing to divide each group. The instrument used is to measure the strength of the leg muscles, namely the leg and back dynamometer, while the power of the limbs uses vertical jump. The data analysis technique used is ANOVA two-way. The results showed that: (1) There was a significant difference in influence between plyometric side-to-side box shuffle and box jump exercises against power limbs in wrestling athletes, with a value of F 4.865 and a significance value of p 0.045 < 0.05. The side-to-side box shuffle exercise group was higher (good) compared to the box jump exercise group with a post-test average difference of 8.41. (2) There is a significant difference in influence between athletes who have the high and low leg muscle strength to leg power in wrestling athletes, with proven valueS F 20.74 and significance values p 0.000 < 0.05. Athletes who had high leg muscle strength were higher (good) compared to players who had low leg muscle strength, with an average post-test difference of 17.38. (3) There is a significant interaction between plyometric exercises (side-to-side box shuffle and box jump) and leg muscle strength (high and low) to leg power in wrestling athletes, with a value of F 41.819 and a significance value of p 0.000 < 0.05. There is a significant difference in influence between plyometric side-to-side box shuffle exercises and box jump on the increase in leg power in wrestling athletes. The side-to-side box shuffle exercise group was higher (good) than the box jump training group against the increase in leg power. There is a significant influence comparison between athletes who have high and low leg muscle strength to the increase in leg power in wrestling athletes. Athletes who have high leg muscle strength are higher (good) than athletes who have low leg muscle strength against the increase in leg power. There is a significant interaction between plyometric exercises (side-to-side box shuffle and box jump) and leg muscle strength (high and low) to the increase in leg power in wrestling athletes.
