    This study was to perform the kinetic analysis of tucked backward salto on the balance beam. Eight womern`s gymnastics players (age: 15.88±2.45 yrs, career: 6.38±0.52 yrs, height: 152.38±7.35 cm, weight: 44.25±7.54 kg) of the I-region participated in this study. The kinematic variables were analyzed response time of motion, angle, velocity, acceleration and the kinetic variables were analyzed ground reaction force (GRF) of motion. For measure and analysis of kinematic and kinetic variables of this study, used to synchronized to 6 Eagle camera and 1 force plate, used to the Cortex (Ver. 1.0) for analyzed of variables. The results were as follows; To the kinematic variables of tucked backward salto on the balance beam, a time appeared longer landing than air rotation, changes of angle regulated segment of body smaller moment of inertia when air rotation, larger moment of inertia when releasing and landing. A velocity appeared fast motion when releasing and air rotation of body, but appeared more decelerations from landing and acceleration showed to be tended to velocity. A GRF appears jump more the twice the weight at the moment that showed the power of motion to all subject.
