The purpose of this study was conducted to analyze the variation of the kinetic variables of Lower limbs depending on taping type during drop-landing and comparatively analyze the jump performance so as to analyze the effect of taping on injury prevention and exercise performance ability. The subjects of this study were 7 male basketball players with stable ankle joints. They performed drop-landing motions in conjunction with 3 taping types: C-type(inelastic tapping), K-type(elastic taping) and N-taping(without taping). To exclude the learning effect from repetitive motion, test was performed over three days. To calculate kinematic variables, the data obtained by using 6 infrared cameras, force plate and the electromyogram data through Kwon3D XP and Myoresearch; the data calculated was analyzed using SPSS 18.0 through One-Way ANOVA, correlation analysis and linear regression analysis; and the significant level was set at .05. The final data was comparatively analyzed. The results can be summarized as follows.

First, the effect of taping for the players with stable ankles was minimal and the high load on ankle joints offset the fixing effect of inelastic taping. Thus the inelastic taping for the players with stable ankles did not have an effect on the control of dorsal flexion during one-foot landing.

Second, increasing angular velocity by increasing the movable range of knee joints disperses impact forces, yet inelastic taping restricted the range of knee joint motion and at the same time increased angular velocity, adding to a negative effect on knee joints.

Third, inelastic taping induced inefficient motion of Lower limbs and unstable impact force control of ankle joints at the moment of landing and produced maximum vertical ground reaction force, which led to an increase of load.

Fourth, inelastic ankle taping did not have an effect on the maximum vertical jump height, yet increased knee joint power.

Finally, the coordination between angular velocity and joint movement varied depending on the type of taping. For stabling landing dispersing external impact force delivered to knee joints, taping treatment should be avoided.

Sixth, knee joint moment and vertical ground reaction force showed stabling landing in the range of joint motion and negative correlation, yet inelastic taping did not show a correlation, resulting in inefficient landing motion.

Seventh, the effect of the kinematic variables of ankle joints on the kinematic variables of knee joints varied depending on the type of taping, indicating inelastic ankle taping had a negative effect on knee joints. Eighth, the inefficient motion of Lower limbs because of inelastic ankle taping has increased knee joint momentum.
