Abstract [en]

The purpose of this study was to investigate: (1) If variables from one-leg drop jump (DJ), DJ, squat jump (SJ), and counter movement jump (CMJ) tests can predict sprint performances for sprinters. (2) If sprinters and jumpers can be distinguished based on variables from one-leg DJ, DJ, SJ, and CMJ tests, also if sprinters and throwers can be distinguished based on variables from stiff leg jump (SLJ), SJ, and CMJ tests. A single linear regression and multiple linear regression analysis approach with models including two or three variables were used when predicting sprint performances. Five elite sprinters (1 female) participated in the first subexamination and five sprinters (1 female) vs five jumpers and six sprinters vs. six throwers (4 females) participated in the second. The force variable CMJ peak force relative to body weight significantly predicted the sprint performances maximal running velocity through 10 m (Vmax10m) and 60 m time. Vmax10m was also predicted by CMJ height. Jump heights from SJ and DJ did not predict sprint performances. The between group analysis of the athletes showed a non-significant group difference with respect to the jump variables. However, planned comparisons between sprinters and throwers showed significant differences on a number of SLJ variables. When constructing training programs for sprinters, aim should be to improve CMJ peak force and CMJ height because of the prediction of Vmax10m and 60 m time, presumably due to velocity specificity components.
