Sažetak
Sprinting speed is a complex ability whose physiological basis is mostly genetically defined. Top competition results are therefore as a rile attainable only for a small, select number of individuals. The purpose of this study was to find the most important kinematic and dynamic parameters, their developmental trend and their influence on the efficiency in maximal sprinting speed for young sprinters of both sexes, from eleven to eighteen years of age. We recorded kinematic and dynamic parameters with locomometer. The vertical pressure on the surface was calculated by biomechanical modelling of running steps. We calculated correlation between maximal sprinting speed and Kinematic and dynamic parameters. The results show, for both sexes, that the structure of the sprint stride changes drastically in connection to the stride length and frequency, the ratio between the contact and the flight phases and the vertical pressure on the surface. The correlation coefficients show that the duration of contact (R=0.71), the relative stride frequency (R=0.52) and the vertical pressure on the surface (R=0.89) are good indicators of the sprinting potential of young runners.
