Popis:	97 The purpose of this study was to investigate the difference between high-performance and normal-performance children standing long jump performance via analyzed kinematic and kinetic data. 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).
