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 digit1 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 a
