Do you ever feel sore after exercise? Exercise physiologist Andrew Cate explains why muscle soreness occurs, and what you can do to prevent it.

What is delayed onset muscle soreness?

Delayed onset muscle soreness (DOMS) is a condition involving muscular pain which occurs one to three days after physical activity. It's more likely to happen to people embarking on a new exercise program, or who are engaging in a new activity, especially: For example, if you run three times a week on a regular basis, but play a random game of tennis, you may still experience DOMS. The actual pain is thought to be an inflammatory response that occurs due to micro-tears in the muscle fibres.

Other symptoms of DOMS may include reduced range of motion, reduced muscle strength, and swelling or tightness. It's thought DOMS may be a protective mechanism that assists in muscle repair, as the body makes it difficult to perform similar movements in the days afterwards.

Tips to minimise and prevent DOMS

Most people who exercise will experience DOMS at some point in their lives. But there are strategies you can adopt to prevent DOMS, or minimise its impact:

Tips for the treatment of DOMS

If you are experiencing DOMS, the following strategies may help to reduce its severity and duration.

How to tell the difference between DOMS and a cramp

There are some distinct differences between a muscle cramp and DOMS. Cramps occur suddenly and are an extremely painful muscle contraction. Unlike DOMS which occurs after exercise, cramps usually occur during exercise, especially once fatigue has set in.

Another significant difference is that you may still be able to perform light exercise with DOMS, while it’s virtually impossible to continue exercising during a cramp.
