TO ASSESS THE COMPLEXITY OF MOVEMENTS IN SKI RUNS
The complexity of sports movements is an important factor affecting the process of formation of motor skills, and, ultimately, the effectiveness of technical training. The complication of the composition of the movement requires additional time and energy costs to develop and consolidate the coordinated interaction of the links of the musculoskeletal system. This may be an important factor in the formation of new ways of performing competitive movements, in particular, modern moves in cross-country skiing. In this regard, there is a problem of developing methods for assessing the complexity of movements. This article presents some results of such an assessment by measuring the delay time of the start of movement when an audio signal is given. This time is used as an indicator of the level of intermuscular coordination. The results of experiments to determine the delay time in test exercises of four types modeling the complication of the movements of the skier's hands are presented. The problem of using ski poles at high speeds is touched upon.
