Table 1 Unilateral values (Mean ± SD) for the variables of vGRFmax, vGRFmean (outside phase); vGRFmin, vGRFmean (inside phase); vGRFmin, vGRFmean (edge changing phase) determined by pressure insoles (PI) and force plates (FP) depending on the test situations: expert (n=10) vs. intermediate (n=10) level skiers, low vs. high dynamic skiing modes, on 15° (flat) vs. 23° (steep) slopes. When global significances for the factor “system” were observed, paired-sample t-tests between the force determined by the FP and the PI were additionally carried out. Significant differences between the systems are indicated by |
