如果你已经有一段时间没有从事某种运动,当突然开始锻炼时,会在第二天感到肌肉疼痛,这是为什么?这种类型的疼痛称为延迟性肌肉酸痛,通常在事后几小时内发生,并在接下来的几天里加剧。会导致延迟性肌肉酸痛的运动由偏心(拉长)肌肉收缩组成,这时肌肉在收缩时反被拉长。下楼梯或下坡就是这样的例子,大腿前侧肌肉在支撑身体重量的同时被拉长。 If you have not exercised for some time, when you suddenly start exercising, you will feel muscle pain the next day. Why is this type of pain called delayed muscle soreness and usually occurs within a few hours afterwards? And intensified in the next few days. A movement that causes delayed muscle soreness consists of eccentric (elongated) muscle contractions, when the muscle is stretched when it contracts. Down stairs or downhill slopes are examples of this. The front thigh muscles are stretched while supporting the weight of the body.
