| Research Abstract |
The purpose of this study was to examine developmental characteristics in neuro-muscular function of lower limb during running and jumping for the elementary school children. The results were follows; 1) Height of CMJ and RJ-index increased with growth. 2) Joint work at the hip in CMJ and at the ankle in 5RJ increased. 3) Pre activity of GA and TA muscles before the foot contact was shown for the sixth grade subject. These results indicate that children acquire motor pattern for counter movement jump and rebound jump and could perform using force enhancement by pre stretch. However, this mechanism can't explain the variation between the grades and within subject.
