Abstract :
This is a badminton game that can be used to improve muscle strength and shoulder flexibility in badminton games. This study uses a survey method with test and measurement techniques. 16 members of the Cicurug Junior High School 2 extracurricular members. The research sample of all members of Cicurug Junior High School was 2 extracurricular members, totaling 16 people, with the sampling technique using total sampling. The instruments used in this study include: (1). Arm muscle strength test (2). Shoulder flexibility test (3). Smash accuracy test. The data analysis technique uses a multiple correlation statistical data collection technique that is the magnitude of the relationship and the contribution of two variables. The results of the study show that. (1). There is a significant relationship between arm muscle strength (X1) and the accuracy of the smash (Y). (2). There is a significant relationship between Shoulder Flexibility (X2) and Smash (Y) accuracy. (3). There is a significant relationship between arm muscle strength (X1) and shoulder flexibility (X2) on the accuracy of the smash (Y). Based on the results of the calculation using multiple correlation techniques obtained by Fcount (18,97)> Ftable (3.81) with a significant level of 0.05, H0 is a meaning that means there is a relationship between arm muscle strength and shoulder flexibility towards the accuracy of the smash in badminton games at Cicurug Junior High School 2. Based on the results of the X1, X2 the correlation there is Y obtained Fcount (18,97)> Ftable (3.81) with a significant level of 0.05. By getting the Rx1x2y 0.863 with a relatively strong and simultaneous construction of R2 x 100% = 0.863² x 100% = 74,47% and the rest 25.53%.
