Sažetak
Alpine skiing is a sport activity requiring a high level of skill and coordination. In course of a run, a competitor skier must be able to energetically change its movement directions adapting to varying environments. Therefore, trained skiers possess a high level of physical abilities. We have approached this problem using a classical biomechanical method that included laboratory and terrain measurements. Laboratory tasks chosen were long jump from a standstill and simulated stepping on a custom designed device, and terrain tasks included defined skiing movements. During these tasks four EMG channels (m. rectus femoris, m. vastus lateralis, bilaterally), ground reaction force, and some kinematic variables were registered. Subjects ranging from ski instructor to top level competitor of an olympic level participated in our laboratory testing. Measured signals were processes and significant differences in signal parameters were found, reflecting the level of acquired movement skill in our sample of subjects. The feature marked the most was a very effective contraction-relaxation cycle of the monitored musculature found in top competitors. This approach seems suitable for evaluating the training state of skiers in course of their preparation for a season.
