スポーツ科学研究, 11, 69-130, 2014 年  70  Analysis of sprint ability in elementary school children  Sakie Nobuoka1, Hiroyasu Tsuchie2, Takatoshi Higuchi3,Tetsuya Ogawa3, Kazuyuki Kanosue3 1Graduate school of Sport Sciences, Waseda University  2Josai University  3 Faculty of Sport Sciences, Waseda University  The purpose of this study was to analyze sprint ability in elementary school children. We especially investigated the relationship between foot contact type and sprint abilities in school children from 6 to 12 years of age. 687 children (352 boys and 335 girls) who run 50m sprint during their school’s fitness test were analyzed. Their mean foot contact time (T-c) and aerial time (T-a) during the interval 20-30m were calculated from video images captured by a high-speed video camera (300 frames/second). To control the effect of physical development, data were standardized with the mean value in each school year. In addition, their types of foot contact were classified into fore-foot, mid-foot and rear-foot types. As a result of statistical analysis, sprint time was significantly and positively correlated to T-c (boys; r = 0.75, P<0.01, girls; r = 0.72, P<0.01) but not to T-a. The sprint time was negatively correlated with ratio of aerial time to foot contact time (T-c /T-a, boys; r = -0.61, P<0.01 girls; r = -0.54, P<0.01). 70% of boys and 87% of girls belonged to rear-foot type. They also have tendency of longer T-c compared with other two types (P<0.05). From these results, T-c and T-a/T-c could be the key factors for sprint abilities of elementary school children, and also these factors could be influenced by their foot contact types.
