摘要

目的开发指长比在泰拳运动员选拔中的应用技术，为提升泰拳运动竞技水平提供实践指导。方法采用滚雪球抽样和简单随机抽样相结合的方法，在泰国曼谷共选取研究对象413名，其中男性泰拳职业选手84人，女性泰拳职业选手62人，普通男性大学生137人，普通女性大学生130人。测量研究对象的指长，并计算其指长比。采用SPSS 20.0统计学软件进行判别分析。结果男性泰拳职业选手，2D∶3D、2D∶4D、2D∶5D、3D∶4D和3D∶5D均显著低于普通男性泰国人群，女性泰拳选手的2D∶4D、3D∶4D和3D∶5D均显著低于普通女性泰国人群，以上差异均有统计学意义（P<0.05）。不管是全模型法还是逐步法，所建立的判别函数均有显著统计学意义，且正确判别率较高，稳定性较强。男性人群的正确判别率总体上高于女性人群。在区分泰拳职业选手与普通泰国人群时，男性2D∶4D的最佳临界值为0.951，女性为0.960。结论采用指长比构建的泰拳职业选手与普通人群的判别模型，能够为泰拳运动员选材提供重要参考。

Abstract

Objective To develop the application technology of finger length ratios in the selection of Muay Thai athletes, and to provide practical guidance for improving the competitive level of Muay Thai. Methods By using the method of snowball sampling and simple random sampling,413 subjects were selected in Bangkok, Thailand, including 84 male Muay Thai professional players, 62 female Muay Thai professional players, 137 ordinary male college students and 130 female college students. The finger length of the subjects was measured and their finger length ratios was calculated. SPSS 20.0 statistical software was used for discriminant analysis. Results The 2D∶3D, 2D∶4D, 2D∶5D,3D∶4D and 3D∶5D of male Muay Thai professional players were significantly lower than that in the general male Thai population, and the 2D∶4D, 3D∶4D and 3D∶5D of female Muay Thai players were significantly lower than that in the general female Thai population, and the above differences were statistically significant (P<0.05). Discriminant functions developed using both the full model and stepwise method were statistically significant, demonstrating high accuracy and stability. The correct discrimination rates were higher in the male population than that in the female population.When distinguishing between Muay Thai professional fighters and the general Thai population, the optimal 2D∶4D threshold for males is 0.951, and for females, it was 0.960. Conclusion The discriminant model of Muay Thai professional players and ordinary people based on the ratios of finger length can provide important reference for the selection of Muay Thai athletes.
