Influence of Angular Values of Body Segments on the Distance of the Throw Out In (Z) Axis
Abstract:
This research was carried out on atop atlete, representative of Bosnia and Herzegovina, with the aim of determining the significance and magnitude of the angle value impact (A) of the body segments in the projection (Z) or the sphere length of the sphere 0.1 s before the spit.
When selecting variables, it was taken into account that they satisfy the basic metric characteristics (validity, relievability, objectivity, sensitivity ...) and that they are aligned with the technology and instrumentation used to capture and determine their kinematic parameters. In order to determine the magnitude and size of the influence of kinematic parameters of the individual shot put elements (A) in the projection (Z) or 0.1 s before the ball spout (predictor set of variables) on the length (range) of the sphere (criterion variable), regression analysis was used. The regression results of the analysis indicate that there is a statistically significant influence of the angle position (A) of the body segments in the projection (X) or the length of the sphere 0.1 s before the throw-out.
Analysis of the influence of individual variables of the angular position (A) in the axis (Z), shows that the most statistically positive impact on the criterion variable length in the ejection time of 0.1 seconds before ejection has a variable angular position of the left shoulder of the level of the seventh cervical vertebra ( AzLC7R). The time span up to 0.1 seconds before the angular position of the left shoulder to the level of the seventh cervical vertebra to the axis (Z) there is as a result of the angular connection (A) of movement in the vertical extension expressed body axis (Z) relative to the projection of the moment of casting and reconciliation.
