Abstract

The use of proper and correct plyometric training methods will increase strength and speed in performing basic volleyball techniques. From the plyometric exercise method, especially squat jump and double leg bound exercises, it is estimated to have an influence on leg muscle power. This research will be carried out in the courtyard of SMP Negeri 3 Karanganyar, Jalan Lawu No. 86, Ngarjosari, Karanganyar Regency, Central Java. This research will be carried out for six weeks starting on February 5, 2024 to March 16, 2024 with a frequency of meetings three times a week on Monday, Wednesday and Friday. The experimental method is chosen to determine certain symptoms through the treatment carried out on the experimental sample. An experiment is a pattern that allows researchers to simultaneously study the influence of two or more types of experimental variables. There was no significant difference in height increase between the squat jump and double leg bound treatment groups. Evidenced by the average increase in the squat jump treatment group by 5.7 (2.544%) while in the double legbox bound treatment group by 6 (2.819%). As well as the results of the statistical test of the anova test obtained a probability value of 0.436> 0.05.
