Abstract:
This form of research is correlational research penjaskesrek fourth semester student population. The sampling technique in this research by using total sampling, where samples preformance this research is the population of 20 people. Instruments that do ntuk collect data in this research is to use the test and direct measurement of leg muscle explosive power with style flop high jump results. Explosive leg muscle power measurement using Degnan MD jump for high jump and flop style with a test jump 3 times. This study aims to determine how much information the relationship between leg
muscle explosive power with the result flop style high jump, as well as to determine whether there is any information about a meaningful relationship between the two variables. The data obtained as a result of the research is quantitative data through tests and measurements which will then be processed with statistical normality test done to test Liliefors at level α = 0.05. To find out how much the relationship between the two variables can be determined by using the product moment formula, sedagkan to find significant correlations can be determined by using t-test. Based on the research results, it can be concluded that there is a significant relationship between leg muscle explosive power with the result flop style high jump, where the level of α = 0.05 obtained t 4.3 1.734 so t tabel Ho is rejected and Ha accepted, donations variable X the Y variables considered sufficient and obtained r = 0.71.
