Kontribusi Daya Ledak Otot Tungkai dan Kelentukan Pergelangan Tangan terhadap Ketepatan Smash Bulutangkis

Abstract

This study aims to determine the explosive power of leg muscles, wrists formation, and know their
contribution to the accuracy of jumping smash badminton. The type of this research was correlational. The population
of this research is 54 people, the sample is taken by purposive sampling so that the sample is 25 people. Limb muscle
explosive power data obtained from a vertical jump, wrist shape by measuring wrist range, precision jumping smash
took smash accuracy test. Data were analyzed by using product moment correlation analysis and contribution (r² x
100%) with significance level α 0,05. Data analysis of explosive muscle limb power was obtained score = 0,4450 and
table = 0,396. Its contribution to the accuracy of jumping smash players is 18.14%. Data analysis of wrist formation
was obtained score = 0,5021 and table = 0,396. Its contribution to the accuracy of jumping smash is 23.31%.
Analysis of explosive muscle limb power data and wrist joints together contributed 46.83% to the accuracy of jumping
smash
