The aim of the study was to investigate the influence of karate fights on Achilles tendon stiffness in karate competitors. Eleven male karate fighters participated in the present study. A handheld MyotonPRO device (MyotonPRO, Myoton Ltd, Estonia) was applied to measure Achilles tendon stiffness in karate fighters. The Achilles tendon was tested 5 cm above the tuber calcanei. Stiffness measurements were performed before and after eight sparring fights. Each fight lasted 2 min and was separated by a 2 min rest period. Achilles tendon stiffness for the dominant leg increased significantly from before fights (751.57 ± 123.493 N/m) to immediately after fights (809.43 ± 160.425 N/m) (p = 0.012). Presented results should be used by strength and conditioning coaches in training programs as a way to decrease the risk of injury.
本研究的目的是调查空手道比赛对空手道运动员跟腱刚度的影响。11名男性空手道运动员参与了本研究。使用手持式MyotonPRO设备(MyotonPRO,Myoton有限公司,爱沙尼亚)测量空手道运动员的跟腱刚度。在跟骨结节上方5厘米处测试跟腱。在八次对练比赛前后进行刚度测量。每场比赛持续2分钟,中间间隔2分钟休息时间。优势腿的跟腱刚度从比赛前(751.57±123.493N/m)到比赛后立即显著增加(809.43±160.425N/m)(p = 0.012)。力量和体能教练在训练计划中应采用本研究结果,以降低受伤风险。
