Abstract

This study aims to determine the contribution of leg muscle explosive power and self-confidence to the 50 meter sprint of the students of State Junior High School 22 Pekanbaru. The type of research used in this study is a correlation. The research instrument used was a standing broad jump test, a questionnaire and a 50 meter sprint test. According to data analysis and hypothesis testing, the contribution of leg muscle explosive power to the 50 meter sprint or variable X1 to Y is obtained rcount < rtable or 0.201 < 0.576 using a contribution value of 4.00% while the remaining 96% run is determined by the another factor, to be confident in the ability to run 50 meters sprint or X2 to Y variables obtained rcount < rtable or 0.250 < 0.576 using a contribution value of 6.20% while the remaining 93.80% is influenced by other factors, while donating muscle explosive power limbs and confidence in the ability to run 50 meters sprint or variables X1, X2 to Y obtained rcount < rtable or 0.527 < 0.576 it is known that there is a significant explosive power of leg muscles and confidence in the consequences of running 50 meters sprint and there is a contribution to the ability to run 50 meters sprint The number of students of SMP Negeri 22 Pekanbaru was 27.70% and the remaining 72.30% was influenced by other factors
