Method: Twenty male college table tennis players were selected. All subjects had resistance training and enhanced training experience. There was no history of upper limb and lower limb injury within one year. No upper or lower extremity surgery was performed in the past. Kinematics and kinetic data were analyzed using 11 motion-infrared cameras (200 Hz sampling rate) and 1 force platform (2000 Hz sampling rate). Statistical analysis was performed using SPSS 18.0 software with dependent samples t-test statistics to compare the difference of the parameters between the arch support insole and flat insole. The significance level was set as α=0.05. Result: Ankle flexion changes, foot abduction angle changes, and heel left and right displacement parameters of arch support insoles were smaller than those of the flat insoles (p = 0.040, 0.022, and 0.047). The knee flexion angle changes and the maximum posterior ground reaction force were higher than those the flat insole (p = 0.011 and 0.001). Conclusion: The posterior ground reaction force in the arch support insole was large, indicating that the athlete got more brake from the ground as a support. At the same time, the knee flexion was increased as absorption and the hip stability was enforced for the propulsion and quickly hitting the next ball. In the arch support insole, these minor changes can greatly affect the movement of the table tennis and the execution of the forehand shot using the footwork.
