KONTRIBUSI KELENTUKAN TERHADAP KETERAMPILAN TENDANGAN LINGKAR DALAM TARUNG DERAJAT DI SATLAT UNP KOTA PADANG

Abstract

This study aimed to determine the contribution of flexibility to the skill of executing the inner round kick (tendangan lingkar dalam) in Tarung Derajat athletes at the training units of UNP and UIN Imam Bonjol, Padang City. The research used a quantitative correlational approach with 30 athletes as samples (15 from UNP training unit and 15 from UIN Imam Bonjol training unit). Flexibility was measured using the sit and reach test, while round kick skill was assessed using a validated technical assessment rubric. Data analysis employed Pearson product-moment correlation and simple linear regression. The results showed a low positive correlation (r = 0.222) with a low determination coefficient (r² = 0.0494), indicating that flexibility contributed only 4.94% to round kick skill, with the remaining 95.06% influenced by other factors. The t-test results (t-count = 1.206 < t-table = 2.048) indicated no statistically significant contribution. The study concluded that while flexibility is a supporting component, round kick skill in Tarung Derajat is predominantly influenced by other physical components such as leg muscle power, rotational coordination, dynamic balance, and motor pattern mastery.
