女生的力气有多大?研究:答案全在手上

女生的力气有多大?研究:答案全在手上

当你感叹自己力气不够大时,有没有想过决定自己力量的秘密就在手掌上……

当你感叹自己力气不够大时,有没有想过决定自己力量的秘密就在手掌上……

Researchers found that women who have an index finger that's shorter than their ring finger could actually have more strength.研究表明食指比无名指短的女性可能更加强壮。

来自奥地利的研究团队分析了手掌握力与人们第2和第4根手指长度的比率关系(handgrip strength and people's 2D:4D ratios)。研究结果发表在《英国皇家学会学报B辑》(Proceedings of the Royal Society B)上。

啥是2D:4D比率

 

The 2D:4D ratio is the most studied digit ratio and is calculated by dividing the length of the index finger of a given hand by the length of the ring finger of the same hand.2D:4D比值是最常被研究的数字比值之一,它的计算方法是将某只手的食指长度除以同一只手的无名指长度。

许多研究表明,2D:4D数字比率与各种身体和行为特征之间存在相关性。

不少过去的科学研究已经发现,这一比例与男性力量有关,但它与女性力量的关系还不明确。参与该项研究的学者Katrin Schäfer表示,这一理论对女性同样适用。

In experiments, women with a lower 2D:4D ratio tended to have higher grip strength than women with a higher 2D:4D ratio, the researchers found. 在实验中,研究人员发现2D:4D比例较低的女性往往握力更高。

换句话说,无名指比食指长表明握力更强、肌肉更健康。

A lower 2D:4D ratio – and higher prenatal testosterone exposure – is linked to higher grip strength in adulthood.2D:4D比率越低,胎儿在子宫内接触到更多的睾酮,因此长大后握力更高。
