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.

在經過艱苦的鍛鍊或一天的體力活動後，你經常會發現肌肉疼痛，但這些疼痛從何而來呢？據一位德國教授說，疼痛來自於非同尋常的肌肉拉傷，例如，騎自行車去兜風，因爲你已經很長時間沒騎了。疼痛的發生是因爲你的腿部肌肉不習慣這種運動。當肌肉進行某種偶然的活動時，肌肉內的細小纖維就會被撕裂。隨着肌肉痠痛的發展，身體必須努力修復肌肉撕裂，但這個修復過程不會馬上就發生。首先，身體必須意識到肌肉受損。當身體意識到肌肉受傷時，對此的反應是增加流向該區域的血流並增加體溫，然後，受損的細胞被清理乾淨，身體派出專門針對於此的細胞來分解大的肌纖維碎片。癒合可以發生在這之後。這些細胞到達你患處大約需要一天的時間。這就是爲什麼與肌肉痠痛相關的延遲最常見的原因。受損細胞的修復需要大約兩天，然後疼痛消失。不幸的是，幾乎沒有什麼東西可以減輕肌肉痠痛。止痛膏不起作用，但衝個熱水澡或泡個溫水浴可以緩解疼痛。
