Sport Performance Structure in Female Pole Vault from the Point of View of Physical Activity Kinematic Parameters
This research is oriented at explanation of sport performance by angle, speed, time and space char acteristics of centre of gravity, positions of body, extremities and pole during approach, take off and jump realization in female pole vault. Kinematic parameters were gained by two dimension analyser Consport Motion Analysis System (CMAS) There are involved 19 female pole vault jumpers with sport performance 408.1 490.5 cm (average result 431.2 cm) From the point of biomechanical movement activity analyse we consider as a more objective performance criterion (dependent variable) maximal centre of gravity height that were reached at valid attempts by female pole vault jumpers. By two dimension (2 D) analyse of group of female pole vault jumpers there were revealed 76 independent variables that entered into process of multiple correlation and regression analysis. On 1st sport structure performance factor level we isolated two complex parameters absolute grip and standing over by which we can explain dependent variable maximal centre of gravity height on 100% With stated proceeding we could separate seven factors on 2nd level. Three of the parameters horizontal speed of centre of gravity at moment of take off end, centre of gravity height at moment of take off end and operating angle during take off are bound with explanation of absolute grip variable. Four others parameters vertical speed of centre of gravity at the end of pull with turn, centre of gravity height at moment of end of lifting, time duration of take off and climb angle explain standing over. 14 more factors are found on 3rd sport structure performance level. Thus we succeeded in this process to reduce number of decisive variables with their mutual relationships and hierarchy. Transparent and simplified model of female pole vault sport performance structure enables to coaches and jumpers improve technical training.
