Abstract：
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.
摘要：
方向速度(CODS)的变化由几个物理方面决定，比如直线冲刺速度，腿部肌肉的反应力和力量。看来核心力量也可能在CODS中发挥作用，然而,它与CODS的关系尚不清楚。这篇叙述性综述的目的是分析有关a）核心力量与CODS之间的关系以及b）核心力量训练对CODS的影响的文献。该分析揭示了核心力量和稳定性的参数（下肢运动期间激活的核心肌肉的压力和最大自愿收缩的最大平均力输出）与敏捷性T测试中的时间之间的显着关系。然而,该参数与核心肌肉的力量耐力（木板测试的总时间）没有显着相关。核心训练为技能较低的中年青少年运动员的CODS发展提供了足够的刺激,而其有效性在高技能的成年运动员中下降。这些发现表明，核心肌肉力量对方向速度的变化有很大贡献。因此，核心培训对改善CODS很有用。
