## 3 Results
The direction change, although required to be 90\({}^{\circ}\), resulted in approximately 45\({}^{\circ}\) for the coefficient of 0.8 and about 50\({}^{\circ}\) for the other two coefficients, with statistically non-significant changes (\(p>0.05\)). Ankle torque exhibited a significant increase (\(p<0.05\)) as the shoe outsole friction coefficient increased, suggesting an elevated risk of injury with higher coefficients. Tables 6 and 7 present comprehensive findings related to the full approach jump. Similar to the observations in defensive slide and crossover diribbling, the linear adjustments in the shoe outsole friction coefficient exhibited non-linear effects on the specific parameters governing skill control. In terms of contact time, a substantial and statistically significant reduction (\(p<0.05\)) was evident as the shoe outsole friction coefficient increased from 0.8 to 1.0, indicating a heightened quickness of the jump. However, no further significant decrease (\(p>0.05\)) was noted when the coefficient increased from 1.0 to 1.2. Regarding the anterior-posterior impulse--a crucial factor influencing deceleration in forward motion--we found a significant and noteworthy increase (\(p<0.05\)), signifying a swifter cessation of motion. This was discerned with the rise in friction coefficient from 0.8 to 1.0. Nevertheless, no subsequent significant alteration was observed with a further increase from 1.0 to 1.2. Vertical impulse, associated with jumping height, displayed a comparable pattern, with a significant increase (\(p<0.05\)) observed from 0.8 to 1.0; yet, no subsequent significant change occurred with a further increase from 1.0 to 1.2 (\(p>0.05\)). The jump height exhibited a similar trend to anterior-posterior impulse and vertical impulse. \begin{table}
