Sprinting is characterized by a transition from propulsion via knee extending musculature during initial acceleration towards ischiocrural musculature thereafter. This may lead to a decrease of correlation of the maximal strength in the back squat and sprinting performance with increasing distance. The aim of this investigation was to show the correlation between maximal dynamic force of the extensor chain of the lower limbs and short distance sprinting performance. Therefore, sprinting performance (0-5, 0-10, 0-15, 0-20, 0-25, 0-30m) and one repetition maximum (1RM) of 51 physical education students were determined. Pearson correlation coefficients were calculated and show significant (p < 0.01) correlations for the relationships with the absolute 1RM (r = -0.661 to -0.792) and the relative 1RM (r = -0.648 to -0.739). However, a decrease in correlation over distance was not found. The results show that the maximal strength of lower extremities’ extensors is a basic requirement in short distance sprinting and should be considered in training.
