This study was to analyze the difference between volleyball players and volleyball club members through the 3-dimensional video analysis of required time, physical displacement, angle variables and velocity variables of arms and legs when performing a spike, and to provide useful data for coaches, players, and volleyball members. The followings are the summary of study. 1. In the performance time each phase, player group was longer than club group in every phases except for phase of 2 steps before foot treading. Total time required was 2.531sec for player group, 2.344sec for club group. Player group was 0.187sec longer than club group. 2. In direction of right and left(X), player group moved smaller than club group in every phases except for the phase for landing. In direction of forward and back(Y), player group moved much in impact which is duration section and the phase for landing, while club group moved much in approaching section such as phases of 3 steps before jumping, 2 steps before jumping, 1 step before jumping, and jumping. In direction of upper and lower side(Z), player group moved high in every phases. In moved distance of pace, player group moved longer in phases of 2 steps before jumping, 1 step before jumping, and jumping, while club group moved longer in phases of 3 steps before jumping, impact, and landing. 3. In the angle of shoulder joint which is arms joint in case of impact, player group showed bigger angle than club group. In the angle of elbow joint and wrist joint, player group showed smaller angle than club group. And in the angle of knee joint which is legs joint in case of jumping, player group showed smaller angle than club group. In the angle of foot joint, club group showed smaller angle than player group. 4. In speed of center of body each phase, player group moved fast in the phases of impact and landing. Club group was slightly faster than player group in the phases of 3 steps before jumping, 2 steps before jumping, and 1 step before jumping. In the speed of hand in case of impact, player group was 1212.98sec, club group 1148.06sec - player group was faster than club group. The fastest section except for speed of hand was jumping section for both groups - player group 326.54sec, club group 329.93sec.
