漢英對照/我們曾經認為，伸展肌肉對於溫暖肌肉和準備鍛煉很必要

我們曾經認為，伸展肌肉對於溫暖肌肉和準備鍛煉很必要。 但是，越來越多的研究表明，在熱身之前伸展肌肉實際上會損害肌肉。 當一切變冷時，肌肉纖維尚未準備好，可能會受損。 如果您先運動，血液將流到該區域，這將使組織更柔軟，更容易拉伸。

We used to think that stretching muscles is necessary to warm the muscles and prepare for exercise. However, more and more studies have shown that stretching muscles before warming up can actually damage muscles. When everything gets cold, the muscle fibers are not ready and may be damaged. If you exercise first, blood will flow to the area, which will make the tissue softer and easier to stretch.
