Previous research has shown that kettlebell swings (KBS), utilizing the hip-hinge technique, exhibit similar lower-limb muscle activation patterns to sprint running. This study investigated whether the inclusion of KBS in the warm-up enhances sprint performance. Moderately trained males ( = 12) and females ( = 8) performed KBS and a control (CON) condition (passive rest) in random order before performing three 20-m sprint trials separated by 4 minutes. No condition (KBS versus CON) effects, time effects or condition by time interactions were found for sprint times at 5-m and 10-m. A significant time effect was found for sprint time at 20-m with faster sprint time at 12 minutes compared to 4 minutes ( = 0.022). No condition effect or condition by time interaction was found for sprint time at 20-m. Small to moderate correlations were found for change in sprint time (CON minus KBS) and KBS load at 4, 8, and 12 minutes. It appears the KBS is not effective for potentiating 20-m sprint performance; however, any potential benefit from the inclusion of KBS as a preconditioning exercise for sprinting may be influenced by individual strength capabilities with KBS.
先前的研究表明，利用髋部铰链技术的壶铃摆动（KBS）与短跑具有相似的下肢肌肉激活模式。本研究调查了在热身中加入KBS是否能提高短跑成绩。中等训练水平的男性（n = 12）和女性（n = 8）在进行三次20米短跑试验（每次试验间隔4分钟）之前，随机进行KBS和对照（CON）条件（被动休息）。在5米和10米处的短跑时间，未发现条件（KBS与CON）效应、时间效应或条件与时间的交互作用。在20米处的短跑时间发现了显著的时间效应，与4分钟时相比，12分钟时的短跑时间更快（P = 0.022）。在20米处的短跑时间未发现条件效应或条件与时间的交互作用。在4分钟、8分钟和12分钟时，短跑时间的变化（CON减去KBS）与KBS负荷之间存在小到中等程度的相关性。看来KBS对增强20米短跑成绩无效；然而，将KBS作为短跑的预处理练习的任何潜在益处可能会受到个体使用KBS的力量能力的影响。
