Scientists have found out that women who wear high-heel shoes make the calf muscles shorter. The heels also give many women pain in their legs when they take them off and walk. The researchers tested different women aged between 20 and 50 who wore heels that were 5cm or higher. The research, which covered a two-year period, also looked at women who never wore high heels. The research team used ultrasound to measure the length of the fibres in the calf muscles. Their results showed that the muscle fibres of high-heel wearers were 13 per cent shorter than those in the non-high-heel-wearing women. Lead researcher Professor Marco Narci said: "This confirmed the hypothesis that when you place the muscle in a shorter position, the fibres become shorter.”

科學(xué)家發(fā)現(xiàn)，穿高跟鞋的女性腓腸肌會(huì)變短。脫掉高跟鞋之后行走，她們的雙腿還會(huì)疼痛。研究人員檢測(cè)了20歲至50歲之間經(jīng)常穿5厘米以上高跟鞋的不同女性。該研究歷時(shí)兩年時(shí)間，還觀察了從來不穿高跟鞋的人。研究團(tuán)隊(duì)使用超聲波來測(cè)量腓腸肌纖維的長(zhǎng)度。他們的結(jié)果顯示，穿高跟鞋的女性肌肉纖維比從來不穿高跟鞋的人短13%。首席研究人員Marco Narci教授說：“這證實(shí)了一個(gè)假設(shè)，當(dāng)你把肌肉放在較短的位置，纖維也會(huì)變短。”

The researchers also found that women who regularly wore high heels suffered more muscle aches and pains when they took their shoes off. This is because their muscles are being overstretched for long periods and do not have time to relax. Professor Narci said it was harder for women to stretch their feet out when they took their shoes off. He did advise women to do simple stretching exercises to relieve the pain. "If you stand on your tip toes and lower your heels up and down again it will stretch out the tendons making it easier to walk without heels,” he said. He did not suggest women stop wearing high heels but recommended wearing flat shoes a little more often."Fashion is intended to be uncomfortable and none of the women in the study planned to give up their high heels," he said.

研究人員還發(fā)現(xiàn)，經(jīng)常穿高跟鞋的女性脫下鞋子之后更容易肌肉疼痛。這是因?yàn)樗齻兊募∪忾L(zhǎng)期過度拉伸，沒有時(shí)間放松。Narci教授表示，當(dāng)她們把鞋子脫掉之后更難舒展雙腳。他建議女性做一些簡(jiǎn)單的伸展運(yùn)動(dòng)來緩解疼痛。“用腳尖站立，上下移動(dòng)腳跟，可以伸展肌腱，脫掉高跟鞋之后走路更容易。”他不反對(duì)女性穿高跟鞋，但是建議更經(jīng)常穿穿平底鞋。“時(shí)尚會(huì)讓人不那么舒服，研究中的所有女性都不計(jì)劃放棄高跟鞋。”他表示。
