| Popis | The paper aims to define, by means of correlation analysis, the dependency between the achieved performance and selected kinematic parameters of the technique of top shot putters at the level of 17 - 23 meters, and also after dividing them with discriminant analysis to weaker (17-20 m) and better (20 - 23 m) performances. On the basis of biomechanical analyses of the performances in shot put, and with the help of correlation analysis, we determined the dependence of selected parameters on performance, which essentially determine the length of the shot put. Hypothesis No. 1 has been confirmed as the relationship between the power and velocity of the shot at the moment of release in the whole group of putters was at 1% level of statistical significance (r = 0.68). Correlation between the performance and take-off angle was not statistically significant. The dependence of the performance on speed components of the shot in the moment of release in our study was statistically significant at 5% level only in the horizontal component (r = 0.55). The dependence of release height in the whole group went to 1% level of significance (r = 0.64), thus confirming this parameter to be one of the limiting factors of shot put technique. In the group of 20 - 23 m, the dependence of the angle of take-off was insignificant, with a correlation coefficient r = -0.07, confirming the hypothesis No 2 that assumed the group with better performances will have larger dependence on the release velocity than on the parameter of the angle of take-off. Further research is needed because this work deals only with selected performance parameters and these results do not provide sufficient basis for complex recommendations for comprehensive training. |
