KECEPATAN LARI SPRINT 50 METER PADA MAHASISWA PJKR UNIVERSITAS ROKANIA

Abstract

This research was motivated by several problems that researchers encountered in the field, namely: (1) Weak physical condition of students, especially the explosive power of leg muscles, (2) Running ability is not yet optimal, (3) Lack of physical condition building exercises for students, (4) Lack of facilities. and training infrastructure. The aim of this research is to determine the relationship between leg muscle explosive power and 50 meter sprint running speed in PJKR students at Rokania University. This research is a type of correlational research with a sample size of 8 people and analyzed using product moment correlation. The results of the research show that: There is a significant relationship between leg muscle explosive power and the 50 meter run in PJKR students at Rokania University. The results of Product Moment Correlation analysis show Rcount (0.410) > Rtabel (0.400), while Tcount (1.796) > Ttable (1.746). Thus, it can be concluded that the working hypothesis proposed by Ho is rejected and Ha is accepted, which means that hypothesis one is accepted, namely that there is a significant relationship between leg muscle explosive power and the 50 meter run in PJKR students at Rokania University.
