女生的力氣有多大?研究：答案全在手上

Researchers found that women who have an index finger that's shorter than their ring finger could actually have more strength.

研究表明食指比無名指短的女性可能更加強壯。

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數(shù)字比值之一，它的計算方法是將某只手的食指長度除以同一只手的無名指長度。

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.在實驗中，研究人員發(fā)現(xiàn)2D:4D比例較低的女性往往握力更高。

A lower 2D:4D ratio – and higher prenatal testosterone exposure – is linked to higher grip strength in adulthood.2D:4D比率越低，胎兒在子宮內(nèi)接觸到更多的睪酮，因此長大后握力更高。

Earlier this year, researchers in Scandinavia found hungry people with low 2D:4D digit ratios "make more masculine food choices".今年早些時候，斯堪的納維亞的研究人員發(fā)現(xiàn)，2D:4D數(shù)字比率低的人在饑餓時“會選擇更男性化的食物”。

Also this year, Swansea University researchers found children born to a mother with an above-average income had a lower 2D:4D digit ratio.同樣在今年，斯旺西大學(xué)的研究人員發(fā)現(xiàn)，收入高于平均水平的女性所生的孩子的2D:4D數(shù)字比率更低。

To measure your finger, straighten it and look at the palm of your hand.測量手指時首先把手伸直，觀察一下自己的手掌。

At the base of your index and ring fingers there are likely to be creases. Your index finger is likely to have one crease, the ring finger is a band of creases.食指和無名指指根部有關(guān)節(jié)褶皺。你的食指可能有一條關(guān)節(jié)褶皺，無名指有多條褶皺。

Select the crease closest to the palm and choose a point on the crease midway across the base of the finger.選擇離手掌最近的褶皺的中間點。

Mark it with a pen. Measure it from the mark to the tip of the finger.用筆做個記號。測量從該點到指尖的長度。
