Step kinematic predictors of short sprint performance in field sport athletes
(Prognosewerte der Schrittkinematik für die Kurzsprintleistung in Rasensportarten)
Field sport athletes must generate high velocities over short distances (10 meters [m] or less). The interaction between step kinematics (step length, step frequency, contact time, flight time) determines sprint velocity. This study determined the step kinematics that predicted 10-m sprint performance (0-5, 5-10, 0-10 m intervals) through stepwise multiple regression (p </= 0.05). Spearman`s correlations (p </= 0.05) were also conducted between step kinematics and velocity for each interval. 0-5 m step length and 0-10 m contact time predicted 0-5 m velocity (R = 0.685; p = 0.006). 0-5 m contact time, and 5-10 m step length and step frequency predicted 5-10 m velocity (R = 0.715; p = 0.002). 5-10 m step length and step frequency predicted 0-10 m velocity (R = 0.606; p = 0.001). Correlations were found between 0-5 m velocity and step length in all intervals, and 0-5 m flight time (? = 0.406-0.515; p = 0.011-0.045). 0-10 m velocity correlated with 5-10 and 0-10 m step length, and 0-5 m flight time (? = 0.398-0.444; p = 0.026-0.048). Longer step lengths were integral for short sprint speed in field sport athletes. Step length should be developed in these athletes to improve short distance velocities.
