Analiza mocy kończyn dolnych i różnych typów reakcji u zawodników hokeja na trawie na wysokim poziomie zaawansowania sportowego

The aim of the research was to find out the time reaction in a jump after a sound and visual stimulus. Another aim was to define the power of legs among the hockey field players during the pre-season and start season. The result of the hockey field players’ from AZS AWF Poznań and the Polish National Team were the subject of the research, which was carried out twice by the system of optical research – Opto-jump. The somatic and fat measurements were made. The results of the selected group (Polish National Men’s Team) may give the vision of the model of the players their power of the legs, the reaction time at a sound and visual stimulus. Thanks to these results we can compare them with the league team and follow the changes of the parameters level during the training season. In conclusion the training season didn’t have any essential influence on the measured parameters. The Polish Representation results were at far higher level than the league team. We can confirm that the level of the measured features don’t change in a training year.
