The purpose of this study was to evaluate the spike shoes for the sprint race by the parallel measurement of mechanical power of foot joint and the lower limbs muscular strength. To perform this purpose, the system for the parallel measurement of mechanical power of foot joint and the lower limbs muscular strength was developed. Furthermore, the mechanical power of subject's foot joint in wearing the high performance spike, the general competition spike and the running shoes was measured in the conditions of the plantar flexion jump (PFJ ), the counter movement jump (CMJ) and the drop jump (DJ) using the sliding seat. The experiment led us conclusions as follows; the mechanical power of the high performance spike in DJ was the highest of experimental shoes. The increasing ratio from CMJ to DJ of the high performance spike was the highest of these, too. The iEMG in wearing the high performance shoes in DJ was the lowest. The high performance spike could be output the high mechanical power in the phase of the plantar flexion.
