Sixteen male elementary school children (grade 5) were selected as the subjects and equally separated into two groups. The VICON Motion Capture systems MX-13+ (250 Hz) and the KISTLER force plate (1250Hz) were used to collect the kinetic and kinematic data during standing-long-jump. The selected variables were tested by non-parameter Mann - Whitney U test. The results indicated that the jumping distance and the height variation of CM were significant difference (p< .05). The velocity and level velocity of CM were reach significant difference on initial jumping phase (p< .05). The level impulse and velocity of CM, shoulder joint, elbow, hip joint and knee joint were reach significant difference during propel and takeoff phase (p< .05). en_US dc.description.sponsorship 體育學系 zh_TW dc.identifier GN0095043110 dc.identifier.uri http://etds.lib.ntnu.edu.tw/cgi-bin/gs32/gsweb.cgi?o=dstdcdr&s=id=%22GN0095043110%22.&%22.id.& dc.identifier.uri http://rportal.lib.ntnu.edu.tw:80/handle/20.500.12235/105214 dc.language 中文 dc.subject 生物力學 zh_TW dc.subject 立定跳遠 zh_TW dc.subject 國小學童 zh_TW dc.subject biomechanics en_US dc.subject standing long jump en_US dc.subject children en_US dc.title 國小男童立定跳遠之生物力學分析 zh_TW dc.title The biomechanical analysis of standing long jump on school children en_US
