Abstract
The purpose of this study is to clarify the differences in myoelectric activities and power exerting the lower limbs of the performance that is jumping height is high and low people in the rebound jump. The subjects was 23 male students belong to track and field (age : 20.8 i 0.9 years, height : 179.6 * 6.1 an, and body mass : 82.3 * 17.0 kg). The subjects performed five-repeated rebound jump (5RJ), based on the jumping height of the result, divided into jumping high-high group (GOOD) and the low group (POOR), it was compared with the lower limbs joint power and myoelectric activity. As a result, fi was dearly that differences in the performance of GOOD and POOR has become the appropriate preliminary motion that was preactiviation of the lower limbs muscles in the before foot contact and due to the quick action in take off of the first half.
