— Banjarbaru City volleyball players have smash and block jumping abilities that are still low, so researchers believe that Banjarbaru City volleyball players have poor leg muscle explosive power. This study aims to determine the effect of double leg speed hop plyometric exercises on leg muscle explosive power in volleyball players in Banjarbaru City. The research method used is the method of pre-experiment design, with data collection techniques carried out through initial tests, giving treatment as many as 18 meetings and final tests. The population in this study were all male volleyball players in Banjarbaru City totaling 12 people, while the sample in this study were 12 people with sampling techniques using saturated sampling techniques. The results showed that the pretest data of leg muscle explosive power obtained an average = 55.75 cm with a standard deviation = 8.614. In the posttest data the leg muscle explosive power obtained an average = 59.67 with a standard deviation = 8.988. The analysis results obtained tcount = 15.07> ttable = 2.201, with Sig. (2-tailed) = 0,000; it turns out that Sig. (2-tailed) <0.05 thus the tcount is significant. The conclusion is that there is an effect of double leg speed hop plyometric training on leg muscle explosive power in Banjarbaru City volleyball players.
