plyometric exercises on increasing leg power; (2) the difference in the effect between athletes who have high leg muscle strength and low leg muscle strength on leg power; and (3) the interaction between plyometrics (single leg hop and double leg hop) and leg muscle strength (high and low) on increasing leg power in soccer players. This type of research is an experiment using a 2 x2 factorial design. The population in this study were 38 players from SSB Real Madrid UNY, which were taken based on purposive sampling technique and included as research subjects. The instruments in this study were leg and back dynamo meters and leg power using vertical jumps. The data analysis technique used is a two-way ANOVA. The results showed that: (1) There was a significant difference between single leg hop and double leg hop plyometric exercises on increasing leg power in soccer players, with F value 17.610 and p < 0.05. The single leg hop plyometric exercise group was better than the double leg hop group, with an average difference of 1.9 cm. (2) There is a significant difference in the effect between athletes who have high leg muscle strength and low leg muscle strength on leg power in soccer players, with F value 14.098 and p <0.05. Athletes who have high leg muscle strength are better than athletes who have low leg muscle strength, with an average posttest difference of 1.7 cm. (3) There is a significant interaction between plyometrics (single leg hop and double leg hop) and leg muscle strength (high and low) on increasing leg power in soccer players, with F value 46,878 and p < 0.05.
