Background and Study Aim: The main questions put by the investigators were: a) what was the competitors’ approach to the sport fight along the whole course in alpine skiing, and b) was the information of the runs of the previous competitors important for the next competitors. The first aim of the investigations was acquiring a knowledge on the tactical manner of skiing competitors. The second aim was a proposition of inclusion of some aspects of martial arts into training of skiers.
Material and Methods: Competitions of Alpine Ski FIS World Cup in: downhill, super giant, giant slalom, slalom were evaluated. Altogether 798 starting applications of skiers were noted. Basic geometry of the gates was obtained. All runs were recorded with video camera. Velocities and accelerations of the runs were calculated. Two biomechanical indices were introduced.
Results: Index of skiers’ level was highly correlated with the starting numbers. Index of velocity deviations was higher in technical disciplines comparing to the speedy ones. There is significant difference between better and the worse competitors taking into account tactical approach to the run. Better skiers ran specific fragments of the course with different velocity, hence they obtained shorter time of running.
Conclusions: Some gates were set in wrong manner. Skiers took into account knowledge of the tough fragment of the track and ran it in different way. It would be worthy to implement to the skiers’ training elements of martial arts.
