The purpose of this study was to compare and analyze the effect of tempo on coordination during jump rope. Thirty healthy adult males participated. The task was to jump rope single under with both feet synchronize with metronome tempo(80, 100, 120, 140, 160 bpm). The joint angles and angular velocities of wrist, elbow, shoulder, hip, knee, and ankle were calculated using data stably performed 5 times consecutively among the data performed 10 times in a row synchronize with metronome tempo. And angle-angle diagram, phase plane portraits, and correlation analysis were analyzed using each joint angle and angular velocity. The results of this study were as follows: First, The angle-angle diagrams show that the joint angles decrease as getting faster the tempo. In the wrist-shoulder and hip-ankle diagrams, coupled coordination was observed as getting faster the tempo. Second, In the phase plane portraits, the angular-angular velocity of all joints showed a convex shape. As getting faster the tempo, the angular velocities of the shoulders, hips, and knees decreased. Third, Elbow-shoulder, hip-knee, knee-ankle, and hip-ankle correlation coefficients were high. It was found that the correlation coefficient of hip-knee and hip-ankle decreased as getting faster the tempo. In conclusion, Wrist, elbow, and ankle joints played a more important role in jumping rope than the shoulder, knee, and hip joints. And, When the tempo of jumping rope was 120 bpm or higher, a stable coordination pattern appeared, but when the jumping rope was slowed at a slow tempo, an unstable coordination pattern was observed.
