Abstract

This study aims to determine the Contribution of Wrist Flexibility and Arm Muscle Strength to Smash Badminton in Extracurricular Students at SMA Negeri 1 Teluk Kuantan. This type of research is descriptive with a population of 15 people. All populations were taken as the research sample, thus the sampling technique used total sampling, the data were analyzed using correlational product moment statistics. Followed by a simple linear regression test at the significant level of Kuantan and the Y variable is the Smash hit based on the calculation known r count = 0.67 while r table is 0.482. because r count is greater than r table: 0.67> 0.482 and the variable x2 is the Arm Muscle Strength of Extracurricular Activities at SMA Negeri 1 Teluk Kuantan and the Y variable is the Smash hit based on the calculation known r count = 0.67, While r table is 0.482, because r count is greater than r table: 0.67> 0.482. Thus the variable XI (flexibility of the hand) and variable X2 (muscle strength of the arm) have a significant relationship to Variable Y (Smash). As well as the variable x2 is the Arm Muscle Strength of Extracurricular Activities at SMA Negeri 1 Teluk Kuantan and the Y variable is the Smash hit based on the calculation known r count = 0.67 while r table is 0.482. Because r count is greater than r table : 0.67> 0.482. Based on the results of the above calculations, it can be seen that 0.67 at the 5% significance level is found in r table or 0.67> 0.482 and t table. It can be concluded that there is a Contribution of Wrist Flexibility and Arm Muscle Strength to Smash Badminton in Extracurricular Students at SMA Negeri 1 Teluk Kuantan because KD = 67%.
