The second to fourth finger length ratio (2d:4d) is thought to be related to diverse traits including cognitive ability, disease susceptibility, and sexuality.
To examine the relationship between 2d:4d and sports ability in women.
Hand radiographs from 607 women (mean age 54 years) were used to estimate 2d:4d. Ranking of sports ability was on a scale (1-5).
The highest achieved level of participation in any sport was significantly negatively associated with 2d:4d (b = -4.93, p = 0.01) as was the relationship between 2d:4d and running level (b = -6.81, p = 0.034). Ability in other sports also showed a negative relationship albeit non-significant.
These results suggest that a low 2d:4d ratio is related to increased female sports ability. It can be postulated that this ratio may predict potential sports ability. Understanding the mechanisms underpinning this relationship may give important insights into musculoskeletal fitness, health and disease.
食指与无名指长度比(2d:4d)被认为与包括认知能力、疾病易感性和性取向等多种特征有关。
研究女性的2d:4d与运动能力之间的关系。
使用607名女性(平均年龄54岁)的手部X光片来估算2d:4d。运动能力的排名采用1至5分制。
参与任何一项运动所达到的最高水平与2d:4d呈显著负相关(b = -4.93,p = 0.01),2d:4d与跑步水平之间的关系也是如此(b = -6.81,p = 0.034)。其他运动项目的能力也呈现出负相关关系,尽管不显著。
这些结果表明,较低的2d:4d比值与女性运动能力的提高有关。可以推测,这个比值可能预测潜在的运动能力。了解这种关系背后的机制可能会为肌肉骨骼健康、健康状况和疾病提供重要的见解。
