EFFECT OF DOUBLE LEG BOUND EXERCISE ON EXPLOSIVE CAPABILITY OF LEG MUSCLE POWER IN THE UNMUS VOLLEYBALL MEN'S TEAM

The study aimed to determine the effect of double leg bound training on the explosive ability of limb muscle power on the unmus volleyball men's team. The type of this research is the type of experimental research with this type of research design is the preetest posttest one group design. The population of this study was the Unmus men's volleyball team, which numbered 20 people. The sample of this study was 20 people using a total sampling technique. Explosive Power of leg muscles was measured by vertical jump test with pretest before and poststest after giving training, then the data were analyzed by independent t-test at a significance level (a) of 0.05 with the help of SPSS 22 program. Based on the results of the t test conducted with the SPPS program 22 produces tcount of 3.536 with t table 1.729 at a significant level of 0.05. Means t count> t table, thus the formulation of the hypothesis is that there is the Effect of Double Leg Bound Exercises on the ability of Explosive Power of Leg Muscles in the Unmus Volleyball Men's Team. From the results of the study, it was concluded that there was a significant effect between double leg bound training on the explosive ability of limb muscle power on the unmus men's volleyball team. For sports coaches, especially the coach of the Unmus volleyball team can use the method of double leg bound training as one type of exercise to increase the ability of the leg muscles in addition to other types of plyometric exercises. For penjasorkes teachers and athletes and sports people, it is recommended to do double leg bound training because it can increase jumps.
