ABSTRACT

Reski Amaliah Syam, 2022. The Correlation of Leg Muscle Strength, Leg Length

and Foot Reaction Speed to the 100-meter Running Ability of Athletes Athletic in

Takalar Regency. Supervised by Ikadarny and Haeril.

This research aims to prove the correlation between leg muscle strength and the

100-meter running ability, the correlation between leg length and the 100-meter

running ability, the correlation of foot reaction speed and the 100-meter running

ability, the correlation between leg muscle strength, leg length, and foot reaction

speed simultaneously on the 100-meter running ability. The research method used

is a quantitative research method and this type of research is correlational involving

three independent variables, namely leg muscle strength, leg length, and foot

reaction speed, while the dependent variable is the 100-meter running ability. The

population in this research were athletes athletic from Takalar Regency, with a

sample of 30 people taken by simple random sampling. The data analysis technique

used is the correlation coefficient. The results of the research showed that: 1) There

is a significant correlation between leg muscle strength and the 100-meter running

ability with a value of r = -0.710; 2) There is a significant correlation between leg

length and the 100-meter running ability with a value of r = -0.704; 3) There is a

significant correlation between foot reaction speed and the 100-meter running

ability with a value of r = 0.707; 4) There is a significant correlation between leg

muscle strength, leg length, and foot reaction speed simultaneously with the 100-

meter running ability with a value of R = 0.897.

Keywords: Leg Muscle Strength, Leg Length, Foot Reaction Speed and the 100-

meter running ability.
