| Research Abstract |
A biomechanical study was performed investigating jumping movements used in basketball defense requiring quick and high performance. The results of the study suggested that 1)subjects had better to jump from squatting position with their arms high when they are not required to jump not so high and 2) they should jump from squatting position with their arms low when they are asked to jump in maximal heights. In any case, it was revealed that defenders must set their bodies squatting when they must jump both quickly and highly.
A biomechanical study was performed investigating medio-lateral reaching movements using foot step with and without pre-jump movements. The results of the present study showed that the total reach time (TRT) in the pre-jump condition was significantly shorter compared to the TRT without pre-jump movements. The decrement in the TRT was due to the decrease in the step time (time from the movement onset to the touch down of the step leg), not due to the response time (time from the visual stimulation to the movement onset) and the reach time (time from the touch down of the step leg to the onset of the touch to the target).
