Abstract

Background: The aim of study was to evaluate the effect of kinaesthetic differentiation during the in-run position on the in-run speed and jump length in ski-jumping team.

Material and methods: The examinations were conducted on a group of 14 elite athletes from the A (n = 7) and B (n = 7) national ski-jumping team. The measurement of the angle of attack for an athlete maintaining the in-run position was made using the Zebris CMS 10 device for a precise and replicable analysis of spinal mobility.

Results: Mean length of the jump in the team A was 97.16 (50,95 %) ± 2.78 for the first jump and 93.58 (49.05 %) ±4.23 for the second. In team B, jump length was 87.75 (51.27 %) for the first jump and 83.41 (48.73 %) ±5.77 for a second. The difference between the jump length of the 1st and 2nd jumps was a statistical significance at p < 0.05.

Conclusions: In athletes from team B, lower angular deviations were observed in the in-run position, which means that these athletes were characterized by better reproduced position, whereas they adopted a relatively higher in-run position compared to athletes form team A.
