Abstract
Agility plays an important role at exercise. Twenty seconds side-step is the one of the items in exercise test. Eight senior high school students in the Physical Education Class served as the participants. The purpose of this study was to test wearing different sports shoes such as volleyball shoes, table-tennis shoes, running shoes, the Tug of war shoes and barefoot to do 5 seconds side-step to compare its movement time, time to touch force plates, angle and angle speed of knee joint and hip joint, velocity of body COG and the GRF when touched the force plates. The kinematic variables were captured by the VICON Motion Capture System（250Hz）. The ground reaction forces（GRF） data were collected by three KISTLER force plates（1000Hz）. The Visual 3D and the Vicon Nexus 1.81 software were used to analyze the kinematic and kinetic data of side-step.All the parameters were tested by Friedman two-way analysis of variance nonparametric statistical test by SPSS 12, the significant level was atα＝.05.The results showed that there was a significant difference during the period of leg push off session. We found that wearing volleyball shoes was faster than wearing the running shoes, there were the shorter movement time, shorter the time to touch force plates and greater push off force. The less COG displacement showed the shorter movement time. We recommend that the students can try to wear volleyball shoes and table-tennis shoes to participate the examine test. The students should try to shorten the COG horizontal displacementto reduce the movement time of the side-step.
