The components of leg muscle power, leg length, and pelvic flexion are components that are very supportive in the success of Dollyo Chagi's basic kick technique, because in addition to acting as one of the techniques that can break the opponent's attack, this kick is also one of the factors to produce high points in order to maximize a match. The purpose of this study was to determine how much the contribution of leg muscle power, leg length, and pelvic flexibility in optimizing dollyo chagi kicks in junior taekwondo professional athletes. The sample of this study was 45 athletes from ATIA Lanal Lampung taekwondo. The method used is descriptive correlational. The instrument of this study is that athletes perform dollyo chagi kicks by maximizing leg muscle power, leg length, and flexibility in the hip joint, and the analysis of the data is using product moment correlation. The results showed that there was a contribution to the leg muscles by 58.36% for dollyo chagi kicks, leg length contributed 12.25% to dollyo chagi kicks, and hip joint flexibility in dollyo chagi kicks contributed 28.09%. The relationship between the three components ranging from leg muscle strength, leg length, and hip joint flexibility is very influential with the percentage contributing 67.4% to dollyo chagi kicks. So the results of this study can be concluded that the leg muscle strength component greatly contributes to the ability of dollyo chagi kicks, and the biggest contribution to dollyo chagi kicks is the strength of leg muscles contributing 58.36%. © 2023 by authors, all rights reserved.
