Abstract
An analysis was made of the possibility of executing modern giant-slalom technique variants, and the differences between them, on a sample of seven elite athletes in a simplified competitive situation. The analysis of the selected runs showed that all the athletes were able to perform the turns in given conditions with both giant-slalom techniques – the technique with velocity control and the technique with velocity increase. The analysis of kinematic parameters was limited to the centre of mass (CM) trajectories. The differences were tested with a Student’s t-test for dependent samples. Statistically significant differences were obtained between the two skiing techniques in the athletes’ CM trajectories in the measured area (second and third turns). This fact, together with other proven differences between the trajectories of both techniques, mostly contributed to the confirmation of the advantage of skiing with the technique with velocity increase and the realization of the theoretical and practical background of this study.
