Variable category | Variable code | Variable name | VIF value | Pearson correlation coefficient (with highly correlated variables) | Collinearity diagnostic criteria | Judgment of results |
|---|---|---|---|---|---|---|
Training Schedule | A2 | Training load parameters | 1.85 | Correlation with A3 (training load) r = 0.42 | VIF < 5, r < 0.7 No collinearity | No collinearity |
A3 | Training load | 1.92 | Correlates with A2 (training load parameter) r = 0.42 | VIF < 5, r < 0.7 No collinearity | No collinearity | |
Training conditions | B2 | Training shoes | 1.78 | With B4 (a set of Homo sapiens protective equipment) r = 0.38 | VIF < 5, r < 0.7 无共线性 | No collinearity |
B4 | Personal protective equipment for Homo sapiens | 1.81 | With B2 (training footwear) r = 0.38 | VIF < 5, r < 0.7 无共线性 | No collinearity | |
Damage knowledge | C1 | Knowledge of injury prevention and treatment | 1.67 | Correlation with C3 (Lecture/Case Understanding of Injury) r = 0.45 | VIF < 5, r < 0.7 No collinearity | No collinearity |
Other variables (A1, A4, A5, A6, A7, B1, B3, C2, C4) | - | - | 1.52–1.89 | r < 0.40 (with all variables) | VIF < 5, r < 0.7 indicates no collinearity. | No collinearity |
