The purpose of this research was to investigate the characteristics of the vertical jump of children aged between 1 and 5 years by comparing with the vertical jump of adults. Through 8 Qualisys high speed cameras the kinematics of the vertical jump was captured and recorded at 100㎐. The following variables were calculated joint range of motion (ROM), propulsion time, highest and lowest COM positions, left and right maximum angular velocities and the timing of the maximum angular velocity. In comparison of the ROM of the lower extremities of the children aged 1 and 2 with that of the adults was very small. This meant that the children did barely flex and extend their lower limbs during the vertical jump motion. As for the ROM data of the lower extremities for the adults, showed significantly larger ROMs and a reduced jump preparation time. As for the range of the center of mass (COM) of the subjects, at the lowest COM point the children had a higher COM. Except for the 1-2 year old children there was a significant difference between the maximum angular velocities of the lower limbs. According to the results, age as an internal constraint did not effect the timing of the maximum angular velocity representing the coordinative characteristics of the joints of the subjects older than 3 years old.
