INFLUENCE OF ANTHROPOMETRIC AND KINEMATIC PARAMETERS ON RESULT SUCCESSFULNESS OF SHOT PUT FINALISTS

Anthropometric characteristics and biomechanical parameters alongside with motor and specific-motor skills in great measures define results in athletic throwing disciplines. Their influence is different and often it is an indicator of obtaining good results. Current research is conducted with the finalists of World Championship (Berlin, 2009; Daegu, 2011) with the aim to determine the influence of anthropometric and kinematic parameters of the throw (release velocity, release height, release angle) on result successfulness in shot put. A total of 32 competitors were included in the research, out of which 16 was male(height, 192,13±7,61cm; weight 133,44±14,85kg) and 16 female finalists (height 182,94±6,31cm; weight 95,81±14,28kg). Obtained results were processed by multiple regression analysis which confirmed statistically significant influence of predictors on the result of male shot put finalists (R=0,793**, R²=0,629) and female finalists (R=0,806**; R²=0,650). The obtained results of regression analysis confirmed that the speed of the throw-out (Vo) was a leading parameter in the successfulness of the finalists’ result [Beta(f)=0,691; Beta(m)=0,528] and inverse relation with the angle of the throw-out, which can be confirmed by previous research on this subject. It is interesting that the angle of the throw-out in female shot putters was not defined as a factor of the impact on regression function, while the height of the throw-out recorded slight inversion in comparison to throw-out angle and the speed as a consequence of force of gravity.
