- This study aims to determine the relationship between arm muscle strength and hand eye coordination in extracurricular participants at SMK Negeri 3 Sukabumi against the background, the importance of the role of arm muscle strength and hand eye coordination in badminton This research uses quantitative methods with test and measurement techniques. The research sample was 15 extracurricular participants in SMK Negeri 3 Sukabumi, with a sampling technique using purposive sampling. The instruments used in this study include: (1). Arm muscle strength test (2). Hand eye coordination test (3). Test accuracy forehand service punches. Data analysis techniques using quantitative techniques with multiple correlation statistical analysis that is looking for the magnitude of the relationship and the contribution of two independent variables (X) or more simultaneously (together) with the dependent variable (Y), using SPSS and multiple correlation formulas, testing the significance of Fcount . The results showed that (1). There is a significant relationship between arm muscle strength (X1) and the accuracy of the forehand service (Y). (2). There is a significant relationship between hand eye coordination (X2) and the accuracy of the forehand service (Y). (3). There is a significant relationship between arm muscle strength (X1) and hand eye coordination (X2) with the accuracy of the forehand service (Y). Based on the results of calculations using the multiple correlation technique, the Fcount result is greater than Ftable, namely Fcount (20.21)> Ftabel (3.11) with a significant level of 0.05 then H1 is rejected, meaning that there is a relationship between arm muscle strength and hand eye coordination with the accuracy of forehand service punches in badminton games on extracurricular participants of SMK Negeri 3 Sukabumi. Based on the results of the correlation X1, X2 against Y obtained Fcount greater than Ftable, namely Fcount (20.21)> Ftable (3.11) with a significance level of 0.05. By getting the RX1X2Y calculation results of 0.877 with the category classified as strong and high. And simultaneous construction R2 x 100% = 0.8772 x 100% = 76.9% and the remaining 23.1%. This means that mastery of arm muscle strength and hand eye coordination contribute to the accuracy of forehand service punches in badminton by 76.9% and the remaining 23.1% by other variables.
