This study investigated whether lower extremity stiffness plays a role in the enhancement of change of direction speed (CODS) and the duration of this enhancement after dynamic loaded warm-up (DLWU). Fifteen badminton athletes underwent DLWU, and CODS, individual muscle and tendon stiffness, and vertical stiffness were measured before DLWU and 6, 12, and 18 min after DLWU. The data were analyzed using ANOVA and covariance analysis. Significant improvements in CODS were found at 6, 12, and 18 min post-DLWU compared to pre-DLWU ( < 0.05). The Achilles tendon stiffness of the dominant leg increased at 6 min ( = 0.039) and 18 min ( = 0.024) post-DLWU compared to pre-DLWU. Achilles tendon stiffness of the dominant leg had a significant effect on improving CODS ( > 0.05). CODS improvement lasted up to 18 min after DLWU in badminton athletes, potentially related to increased Achilles tendon stiffness of the dominant leg.
本研究调查了在动态负荷热身（DLWU）后，下肢僵硬度是否在变向速度（CODS）的提高及其提高的持续时间中发挥作用。15名羽毛球运动员进行了DLWU，并在DLWU前以及DLWU后6、12和18分钟测量了CODS、个体肌肉和肌腱僵硬度以及垂直僵硬度。使用方差分析和协方差分析对数据进行分析。与DLWU前相比，在DLWU后6、12和18分钟时发现CODS有显著改善（<0.05）。与DLWU前相比，优势腿的跟腱僵硬度在DLWU后6分钟（=0.039）和18分钟（=0.024）时增加。优势腿的跟腱僵硬度对改善CODS有显著影响（>0.05）。在羽毛球运动员中，DLWU后CODS的改善持续长达18分钟，这可能与优势腿跟腱僵硬度增加有关。
