After tough workout or a day full of physical activity, it's common to find your muscles aching, but where do these pains come from? According to a German professor, the soreness comes from straining your muscles in an uncommon way, for example, jumping on a bicycle for a ride, because you haven't ridden in a long time. Soreness occurs since your leg muscles aren't used to that movement. When muscles perform an activity they aren't regularly expose to, the tiny fibers that are inside them are being torn apart. As muscle soreness develops, the body has to work to repair the muscle tears, but this doesn't happen immediately. First, the body must realize the muscles are damaged. When the body realizes the muscles are hurt, the response is to increase blood flow to the area and increase body heat, damaged cells are then cleaned up and the body sends cells specially designed to break down the large muscle fiber fragments. Healing can take place after this. It takes about a day until these cells make it to your aching muscles. That's why there is most often a delay associated with muscle soreness. Repair of damaged cells takes about two days, and afterwards the soreness disappears. Unfortunately, there is little that can be down to relieve muscle soreness. Pain relieving creams don't work, but a hot shower, or warm bath can provide some relief.

在經(jīng)過艱苦的鍛煉或一天的體力活動(dòng)后，你經(jīng)常會(huì)發(fā)現(xiàn)肌肉疼痛，但這些疼痛從何而來呢？據(jù)一位德國(guó)教授說，疼痛來自于非同尋常的肌肉拉傷，例如，騎自行車去兜風(fēng)，因?yàn)槟阋呀?jīng)很長(zhǎng)時(shí)間沒騎了。疼痛的發(fā)生是因?yàn)槟愕耐炔考∪獠涣?xí)慣這種運(yùn)動(dòng)。當(dāng)肌肉進(jìn)行某種偶然的活動(dòng)時(shí)，肌肉內(nèi)的細(xì)小纖維就會(huì)被撕裂。隨著肌肉酸痛的發(fā)展，身體必須努力修復(fù)肌肉撕裂，但這個(gè)修復(fù)過程不會(huì)馬上就發(fā)生。首先，身體必須意識(shí)到肌肉受損。當(dāng)身體意識(shí)到肌肉受傷時(shí)，對(duì)此的反應(yīng)是增加流向該區(qū)域的血流并增加體溫，然后，受損的細(xì)胞被清理干凈，身體派出專門針對(duì)于此的細(xì)胞來分解大的肌纖維碎片。愈合可以發(fā)生在這之后。這些細(xì)胞到達(dá)你患處大約需要一天的時(shí)間。這就是為什么與肌肉酸痛相關(guān)的延遲最常見的原因。受損細(xì)胞的修復(fù)需要大約兩天，然后疼痛消失。不幸的是，幾乎沒有什么東西可以減輕肌肉酸痛。止痛膏不起作用，但沖個(gè)熱水澡或泡個(gè)溫水浴可以緩解疼痛。
