The Relationship of Leg Muscle Strength and Back Muscle Flexibility to Shooting Results of Futsal Athletes at Ward 13 FC Academy in 2020

This study aims to determine the relationship between leg muscle strength and back muscle flexibility on the shooting results of Futsal Athletes, Ward 13 FC 2020. This research was conducted in the Futsal Field Akademi Bangsal 13 Fc. The population in this study were all athletes of the football school ward 13 as many as 30 people. Sampling was done using purposive random sampling. as many as 10 people were sampled. The data analysis technique used to test the hypothesis is the normality test, linearity test, and correlation test. From the results of the correlation test of the first hypothesis, it was obtained a significance value of 0.043 <0.05, so there is a significant relationship between leg muscle strength and the results of shooting the ball. The results of the second hypothesis test with a significance value of 0.032 <0.05, then there is a significant relationship between back muscle flexibility and the results of shooting the ball. Based on the multiple correlation test in the model summary table, it is known that the magnitude of the relationship between leg muscle strength and back muscle flexibility (simultaneously) on the results of shooting the ball calculated by the correlation coefficient is 0.488, this indicates a moderate effect. Meanwhile, the simultaneous contribution or contribution of leg muscle strength with back muscle flexibility is 23.8%, while 76.2% is determined by other variables.
