Results of the multiple regression analysis assessing the importance of the 30 m/40 m ski difference and 35 m/40 m ski difference in COM speed (vCOM) and COM turn radius (RCOM) to explain the corresponding difference in the dependent variable calculated ground reaction force (FcalcGRF) during the second half of the COM Direction Change II phase (COM DC II, second)
| Predictors of FcalcGRF differences | β-weight | p Value |
|---|---|---|
| 30 m/40 m ski difference (Model*) | ||
| RCOM (COM DC II, second) (30 m/40 m) | −0.865 | 0.002 |
| vCOM (COM DC II, second) (30 m/40 m) | 0.371 | 0.018 |
| 35 m/40 m ski difference (Model†) | ||
| RCOM (COM DC II, second) (35 m/40 m) | −0.687 | 0.002 |
| vCOM (COM DC II, second) (35 m/40 m) | 0.581 | 0.003 |
