The goal of this study is to contribute to explanation of differences in the selected parameters initializing movement of the lower and upper extremities during the running throw-in and to compare the chosen spatiotemporal characteristics of the throw-in after the run up and from the standing position. The research group consisted of n=13 (mean+-S.D.: age=20.28+-0.91 years, height=179.45+-4.62cm, weight=76.15+-3.72kg). length of the throw-in) after the run up than in throw-ins from the standing position.
In standing position throws, a mean value of the longest measured trials was 20.19+-1.52m. In run up throw-ins, the distance of the throws was longer by 13.5% when compared to the throw-ins from the standing position (23.34+-2.75m, p{0.01).
In case of maximal velocity of the ball after the throw-in, the lower mean velocity was registered in throw-in from the standing position (13,92 m.s-1) than in the run up throw-in (14,97m.s-1) (p{0.01). The highest registered velocity (peak velocity by means of the radar gun) after the throw-in from the standing position was 15.61m.s-1 and the minimal speed was 11,72 m.s-1.
When throwing-in after the run up the maximum velocity was 17.21 m.s-1 and the minimum velocity was 13.03m.s-1. The difference in mean altitudes of the throws was statistically significant (p{0.01).
The mean height of the standing position throw was 4.49+-0.93 m and after the run up it was 5.27+-0.90. Fig. 3 presents spatiotemporal characteristics of throw-ins from the standing position and after the run up.On the basis of the data gained, it is possible to assume that, despite the different spatiotemporal parameters of the throw (symmetrical vs. asymmetrical), players may achieve a similar length of the throw.
The recorded differences in throw-in performance should be transformed in physical training of players.
