Abstract

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 team A was 97.16 (50.95%) ±2.78 for the first jump and 93.58 (49.05%) ±4.23 for the second one. In team B, the jump length was 87.75 (51.27%) for the first jump and 83.41 (48.73%) ±5.77 for the second one. The difference between the jump length of the 1st and the 2nd jumps was statistically significant 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 from team A
