Kinematics study on vertical jump between different ability groups

The aim of this study was to investigate the contribution made by the lower limb joints to vertical jump performance by good and poor performers of the vertical jump. Two groups of players were selected who were found to be good and poor jumpers, respectively. The jump performance was recorded simultaneously by means of a force platform and a Vicon motion analysis system. Generally, better jumpers demonstrated greater joint moments, power at the ankle, knee, and as a result jumped higher under both conditions. It appears that the superior performance of the better jumpers was due to greater muscle capability in all lower limb joints rather than to technique.
