The purpose of this study is to clarify the characteristics of the foot pressure distribution of spike-jump in volleyball using an in-sole presser distribution measurement system (Monte system Inc). For this study, seven male and three female university volleyball players were asked to make typical jumps such as vertical jump, 1-step jump, and 3-step jump. The pressure distribution was analyzed in accordance with the three areas of foot. The results may be summarized as follows : 1) In a vertical jump, the sole presser shifts whole sole to toe. 2) On the other hand, a spike jump requires running up, and it increases the pressure to heel, and the wider movement of the pressure-center is also observe. 3) All the subjects made higher jump in the spike-jump than they do in the vertical one; however, the 1-step and 3-step jump do not present significant difference in the height of jump.
