- The Plyometric Roep Jumping is an easy-used training having a cheap tool, and it can be done anywhere, yet it has a good effect on athletes' physical performance. The aim of this research was to know the effectiveness of plyometric rope jumping training using 10, 20 and 30 second-working interval on strength an power of leg muscles. The numer of subjects in this research was 33 trained students which whould be divided into 3 groups of 10 second-working interval (n=11), 20 second-working interval (n=11) and 30 second-working interval (n=11) (controlling group). The measurement of both the strength of leg muscles used Half Squat Jump and the power of leg muscles used Standing Board Jump Test. This researchused consecutive sampling method with pretest-posttest control group design. The research result showed that the variables of strength and power of leg muscles experinced of leg muscles showed that there were no differences among those three groups. In conclusion, plyometric rope jumping training increased the strength and power of leg muscles, although there were no differences among the groups of 10, 20, and 30 second-working interval.
