KONTRIBUSI POWER OTOT TUNGKAI DAN KELENTUKAN TERHADAP TIGER SPRONG

This study aimed to determine the contribution of leg muscle power and flexibility of the basic motor skills of tiger Sprong. The population used in this study amounted to as many as 30 students, with a sample of 30 students, so it was called as sample population (total sampling). Data collection of limb muscle power was using standing broad jump, flexibility was using Flexometer, and data analysis was using was simple linear regression and multiple linear regression. The results showed that leg muscle power have a correlation coefficient of 0.812 and accounted for 65.9%, flexibility has a correlation coefficient of 0.752 accounted for 56.5% while the limb muscle power and flexibility has a correlation coefficient of 0.848 and contributed 71.9% , It can be concluded that the variables that most contributed to the basic motor skills of tiger sprong was limb muscle power that is equal to 65.9%.Penelitian ini bertujuan untuk mengetahui kontribusi power otot tungkai, dan kelentukan terhadap kemampuan gerak dasar tiger sprong. Populasi yang digunakan dalam penelitian ini berjumlah sebanyak 30 siswa, dengan sampel sebanyak 30 siswa, sehingga disebut sampel populasi (total sampling). Pengumpulan data power otot tungkai menggunakan standing broad jump, kelentukan menggunakan Flexometer, serta analisis data menggunakan regresi linier sederhana dan regresi linier berganda. Hasil penelitian menunjukan bahwa power otot tungkai memiliki koefisien korelasi 0,812 dan memberikan kontribusi sebesar 65,9%, Kelentukan memiliki koefisien korelasi 0,752 memberikan kontribusi sebesar 56,5% sedangkan power otot tungkai dan kelentukan memiliki koefisien korelasi 0,848 dan memberikan kontribusi sebesar 71,9%. Dapat disimpulkan bahwa variabel yang memberikan kontribusi terbesar terhadap kemampuan gerak dasar tiger sprong adalah power otot tungkai yaitu sebesar 65,9%.Kata kunci : kelentukan, kontribusi, power, tiger sprong, tungkai
