Why do I feel pain after exercise?
Have you ever felt sore after starting a new activity or pushing yourself harder than usual during a workout?
Muscle soreness that shows up 1 or 2 days after exercising can affect anyone, regardless of your fitness level.
But do not be put off. This type of muscle stiffness or achiness is normal, does not last long, and is actually a sign of your improving fitness.
Find out how to better manage your sore muscles after exercise.
Why do my muscles feel sore after exercising?
Sore muscles after physical activity, known as delayed onset muscle soreness (DOMS), can occur when you start a new exercise programme, change your exercise routine, or increase the duration or intensity of your regular workout.
When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness.
DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid is not involved in this process.
Who can DOMS affect?
Anyone can develop DOMS, even those who have been exercising for years, including elite athletes.
It can be alarming for people who are new to exercise, and may affect their initial enthusiasm to get fit.
The good news is the soreness will decrease as your muscles get used to the new physical demands being placed upon them.
The soreness is part of an adaptation process that leads to greater stamina and strength as the muscles recover and build.
What type of activities can cause DOMS?
Any movement you're not used to can cause DOMS. Taking up a new exercise, a harder than usual workout, or working your muscles in a different way can all cause DOMS.
How long does DOMS last for?
DOMS typically lasts between 3 and 5 days. The pain, which can range from mild to severe, usually occurs 1 or 2 days after the exercise.
This sort of muscle pain should not be confused with any kind of pain you might experience during exercise, such as the acute, sudden and sharp pain of an injury, such as muscle strains or sprains.
How can I treat DOMS?
There's no one simple way to treat DOMS. Nothing is proven to be completely effective.
These things may help ease some of the symptoms:
- ice packs
DOMS does not generally require medical intervention. But you should seek medical advice if the pain becomes unbearable, you experience severe swelling, or your urine becomes dark.
How can I prevent DOMS?
One of the best ways to prevent DOMS is to start any new activity programme gently and gradually. Allowing the muscle time to adapt to new movements should help minimise soreness.
There's not much evidence that warming up will be effective in preventing DOMS. But exercising with warmed-up muscles will reduce your chance of injury and improve your performance.
While stretching has many benefits, there's currently no evidence stretching before or after exercise helps reduce or prevent DOMS.
Can I continue exercising with DOMS?
You can exercise with DOMS, although it may feel uncomfortable to begin with. The soreness should go away once your muscles have warmed up. The soreness will mostly likely return after exercising once your muscles have cooled down.
If you find it hard to exercise, you could rest until the soreness goes away. Alternatively, you could focus on exercises targeting less affected muscles to allow the most affected muscle groups time to recover.
Will I keep getting DOMS?
DOMS is a type of muscle conditioning, which means your muscles are adapting to the new activity. The next time you perform the same activity or exercise at the same intensity, there'll be less muscle tissue damage, less soreness, and a faster recovery.
