Change of direction speed (CODS) is determined by several physical aspects, such as linear sprint speed, reactive strength and power of leg muscles. It appears that core strength may also play a role in CODS, however, its relationship to CODS remains unclear. The aim of this narrative review was to analyze the literature addressing a) the relationship between core strength and CODS and b) the effect of core strength training on CODS. This analysis revealed a significant relationship between the parameters of core strength and stability (the pressure of the activated core muscles during lower limb movement and the greatest mean force output of maximum volunteered contraction) and the time in the Agility T-Test. However, this parameter was not significantly related to the strength endurance of core muscles (total time in the plank test). Core training provides a sufficient stimulus for the development of CODS in less-skilled middle-adolescent athletes, while its effectiveness decreases in higher-skilled adult athletes. These findings indicate that core muscle strength contributes significantly to the change of direction speed. Core training is therefore useful for improving CODS.
变向速度（CODS）由几个身体方面的因素决定，如直线冲刺速度、反应力量和腿部肌肉力量。核心力量似乎也可能在变向速度中发挥作用，然而，它与变向速度的关系仍不明确。本叙述性综述的目的是分析文献，探讨a）核心力量与变向速度之间的关系，以及b）核心力量训练对变向速度的影响。该分析揭示了核心力量和稳定性参数（下肢运动时激活的核心肌肉的压力以及最大自主收缩的最大平均力输出）与敏捷T测试中的时间之间存在显著关系。然而，该参数与核心肌肉的力量耐力（平板支撑测试的总时间）没有显著关系。核心训练为技能水平较低的青少年中期运动员的变向速度发展提供了足够的刺激，而在技能水平较高的成年运动员中其效果会降低。这些发现表明，核心肌肉力量对变向速度有显著贡献。因此，核心训练对提高变向速度是有用的。
