摘要
Ballistic limb motion is enabled by proximal core stiffness. However, controversy exists regarding the best method of training this characteristic. This study sought to determine the most effective core training method to enhance distal limb athleticism. A total of 12 participants (24 +/- 3years, 1.8 +/- 0.05m, 76.8 +/- 9.7kg) consisting of Muay Thai athletes performed a core training protocol (Isometric vs. Dynamic, with Control) for 6weeks, using a repeated measures design to assess performance (peak strike velocity, peak impact force, muscular activation) in various strikes. Isometric training increased impact force in Jab (554.4 +/- 70.1N), Cross (1895.2 +/- 203.1N), Combo (616.8 +/- 54.9N), and Knee (1240.0 +/- 89.1N) trials (P<0.05). Dynamic training increased strike velocity in Jab (1.3 +/- 0.2m<bold>s</bold>-1), Cross (5.5 +/- 0.9m<bold>s</bold>-1), Combo (0.7 +/- 0.1, 2.8 +/- 0.3m<bold>s</bold>-1), and Knee (3.2 +/- 0.3m<bold>s</bold>-1) trials (P<0.05). Isometric training increased Combo impact force 935.1 +/- 100.3N greater than Dynamic and 931.6 +/- 108.5N more than Control (P<0.05). Dynamic training increased Jab strike velocity 1.3 +/- 0.1m<bold>s</bold>-1 greater than Isometric and 0.8 +/- 0.1m<bold>s</bold>-1 more than Control (P<0.05). It appears that both static and dynamic approaches to core training are needed to enhance both velocity and force in distal limbs.
