The cause of DOMS is from eccentric contractions, or when a muscle becomes longer while under tension.

DOMS 是由偏心收缩或者紧张状态下肌肉抻长引起。

In contrast, exposing the muscle to a high-degree of tension, especially while the muscle is lengthening, also called an eccentric contraction, generates effective conditions for new growth.

相反的，让肌肉承受更高的拉力，特别是肌肉在伸展时，又被称作离心收缩，为肌肉提供有效的生长条件。
