Contribution of Leg Muscle Strength and Speed of Students Long Jump Ability

The purpose of this study was to determine how much contribution leg muscle strength and speed against the long jump students of the Faculty of Sport Sciences, State University of Padang.This type of research is correlational research that involved 28 male students.To obtain data, the instruments used were leg dynamometer, the test speed of 40 meters, and the long jump.Data were analyzed by multiple and straightforward product-moment to determine the contribution of used frequency determinant.Based on data analysis found that the results are magnified by leg muscle strength, had no significant relationship with the long jump, characterized by the results obtained by the rcount>rtable, have contributed as much as 47%.From the results obtained running speed of 40 M had no significant relationship with the long jump, characterized by the results obtained by the rcount>rtable, have contributed as much as 22%.There is a significant relationship between leg muscle strength and speed to run 40 M against the long jump students.
