The study investigated the relationship between short sprint performance and mechanical parameters obtained during the acceleration and deceleration tasks with the change of direction (COD) performance in female and male soccer players. The acceleration and deceleration ability were compared in the "High/Fast" "Low/Slow" COD performance group based on a median split analysis in each sex group. One hundred three French soccer players were assessed for the sprinting Force-Velocity (F-V) profile (i.e., theoretical maximal force [F0], velocity [V0], power [Pmax]), 10 m performance, linear deceleration test (maximal braking force [HBF], braking power [BP], deceleration [Dec]), and COD performance using 505-test. The 10 m performance was strongly associated with 505-test performance (ES = [0.64 to 0.71]), whereas the sprinting F-V profiles parameters were weakly to moderately correlated with 505- performance (ES = [-0.47 to -0.38]). The BP was also moderately associated with 505-test performance (ES: range = [-0.55 to -0.46]). In addition, the High/Fast female COD group presented higher F0, Pmax, HBF, and BP than the Low/Slow group, whereas the male groups presented very few mechanical differences. Multiple regression analysis shows that the COD performance of male players was determined by 10 m performance and maximum deceleration power. In contrast, no statistically significant model could be found to determine the change of direction performance in female players. In conclusion, the current finding indicated that the only variable strongly associated with COD performance was the linear 10 m sprint time. In the same way, the mechanical parameters obtained from acceleration and deceleration seemed to play a non-neglectable role in this population.
该研究调查了男女足球运动员短距离冲刺表现与在变向（COD）任务的加速和减速过程中获得的力学参数之间的关系。基于每个性别组的中位数分割分析，比较了“高/快”和“低/慢”COD表现组的加速和减速能力。对103名法国足球运动员进行了评估，包括冲刺力-速度（F-V）曲线（即理论最大力量[F0]、速度[V0]、功率[Pmax]）、10米表现、直线减速测试（最大制动力[HBF]、制动功率[BP]、减速度[Dec]）以及使用505测试的COD表现。10米表现与505测试表现密切相关（效应量ES = [0.64至0.71]），而冲刺F-V曲线参数与505表现的相关性较弱至中等（ES = [-0.47至-0.38]）。BP也与505测试表现中等相关（ES范围 = [-0.55至-0.46]）。此外，“高/快”女性COD组的F0、Pmax、HBF和BP高于“低/慢”组，而男性组的力学差异很少。多元回归分析表明，男性球员的COD表现由10米表现和最大减速功率决定。相比之下，未发现有统计学意义的模型可用于确定女性球员的变向表现。总之，目前的研究结果表明，与COD表现密切相关的唯一变量是直线10米冲刺时间。同样，从加速和减速中获得的力学参数在该人群中似乎也起着不可忽视的作用。
