Specifics of differentiation of force and time parameters for skilled weightlifters

Relevance. A significant power of the exercises performed by weightlifters is associated with the effectiveness of solving speed-power tasks, which depend on the peculiarities of the manifestation of power and temporal accuracy of movements. Regulatory reactions are associated with the level of development of the coordination abilities of the athlete and with his gender. Subjective sensations of perception of power and time parameters underlying the control of movements of weightlifters are an indicator of the intensity of the functioning of the athlete's body, allow you to control the effectiveness of the training process. Insufficient study of indicators of coordination ability in men's and women's weightlifting determined the relevance of this study. The aim of the work was to study the subjective mechanisms of perception of power and time parameters by weight-lifters, taking into account sex differences. Methods. 20 qualified weightlifters of the male and female sex were examined. The ability of athletes to perceive and reproduce the specified values of muscle effort was determined by dynamometry. They calculated the nature of the implementation of errors relative to the given force parameters. The ability to assess the implementation of the «individual second» was investigated using a muscle reflexometer. The relative error and the nature of the reproduction of time were calculated. Statistical analysis was performed using the Student's criterion for unrelated samples using statistica 10. Results. Studies of the accuracy of the perception of force parameters have found fewer errors that occur when reproducing small power loads, and a lower ability to differentiate time parameters in weightlifters. Men had a better ability to differentiate effort when implementing larger weights and more accurate reproduction of time segments with fewer errors in its differentiation. Conclusion. Weightlifters have discovered a certain ability to correctly and accurately distribute power capabilities. A sufficient degree of manifestation of muscular feeling and plasticity of cortical nervous processes characterized the effectiveness of the formation of coordination connections. The value of time intervals, which is the result of integrative brain activity, revealed the closest individual time to an astronomical second. interval in weightlifters, which is due to the need for accurate implementation of the movement at a certain point in time.
