女生的力氣有多大?研究:答案全在手上 A woman’s finger length may determine how strong they are, study says

當(dāng)你感嘆自己力氣不夠大時(shí),有沒有想過決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.
研究表明食指比無名指短的女性可能更加強(qiáng)壯。
來自?shī)W地利的研究團(tuán)隊(duì)分析了手掌握力與人們第2和第4根手指長(zhǎng)度的比率關(guān)系(handgrip strength and people's 2D:4D ratios)。研究結(jié)果發(fā)表在《英國(guó)皇家學(xué)會(huì)學(xué)報(bào)B輯》(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數(shù)字比值之一,它的計(jì)算方法是將某只手的食指長(zhǎng)度除以同一只手的無名指長(zhǎng)度。
許多研究表明,2D:4D數(shù)字比率與各種身體和行為特征之間存在相關(guān)性。
不少過去的科學(xué)研究已經(jīng)發(fā)現(xiàn),這一比例與男性力量有關(guān),但它與女性力量的關(guān)系還不明確。參與該項(xiàng)研究的學(xué)者Katrin Sch?fer表示,這一理論對(duì)女性同樣適用。
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.
在實(shí)驗(yàn)中,研究人員發(fā)現(xiàn)2D:4D比例較低的女性往往握力更高。
換句話說,無名指比食指長(zhǎng)表明握力更強(qiáng)、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,胎兒在子宮內(nèi)接觸到更多的睪酮,因此長(zhǎng)大后握力更高。
不少研究已開始深入分析導(dǎo)致2D:4D比率與握力之間關(guān)聯(lián)的原因。
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(shí)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(shí)“會(huì)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。
如何測(cè)量2D:4D比率
說到這里,屏幕前的你是否已經(jīng)在用尺子量手指了?
別急,接下來CD君將用圖示的方法教大家如何準(zhǔn)確測(cè)量:
To measure your finger, straighten it and look at the palm of your hand.
測(cè)量手指時(shí)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(diǎn)。
Mark it with a pen. Measure it from the mark to the tip of the finger.
用筆做個(gè)記號(hào)。測(cè)量從該點(diǎn)到指尖的長(zhǎng)度。
大家的測(cè)量結(jié)果如何呢?
