Delayed onset muscle soreness. What it is and what you can do to help



Returning to the gym or exercise after a period away often results in a in generalised ache and discomfort in the muscle groups used. This phenomena is often referred to as Delayed onset muscle soreness or DOMS.


What are the symptoms of DOMS ?


Delayed onset muscle soreness is often charcterized by muscular pain that typically peaks 24–48 hours after the exercise and subsides within 96 hours in more significant cases.


The severity of soreness varies as a function of the following factors;

  • How familiar you are with the exercise.

  • The intensity at which you exercised.

  • The eccentric or muscle lengthening component of the exercise.

  • The prior trained state of the muscle or movement pattern.

  • The speed at which exercises were carried out at.

As a rule DOMS is a bigger issue when the exercise is a relatively new large movement pattern or one that hasn't been done in a few weeks or months.


What happens to the muscle to create DOMS ?



First a bit of muscle anatomy and physiology.

Muscle fibres are created by muscle cells called sarcomeres which are essentially a connective tissue framework that houses the active or contractile part of muscle.



When we are exercising and the muscle is stretched under load this is known as an eccentric contraction. DOMS is associated more with eccentric contractions than the concentric or muscle shortening contraction.

During the eccentric contraction the repetitive loaded stretching component cause the damage. This involves :

  • Mechanical disruption to sarcomeres and connective tissue.

  • Inflammation and swelling within the cells.

  • Production of free radicals that cause secondary damage.

It is thought that the muscle tissue that is affected is often the less mature cells or the muscle cells that are ready to be replaced. As dramatic as this all sounds it is a self limiting phenomena that usually peaks at 36-48 hours post exercise and resolves by about day 4.


If you have a good training background the effects are usually less pronounced than if you are starting out for the first time or coming back from a long layoff.


What can you do to ease the effects of DOMS ?


Research published in the Scandinavian Journal of Medicine and Science in Sports found that marathoners consuming tart cherry juice five days before, on the day of, and 48 hours following their races reduced muscle soreness. And how’s this for the cherry on top? The athletes also showed signs of improved muscle recovery and function.

Tart cherries are rich in anthocyanins, colorful antioxidant compounds that are believed to work their magic by decreasing the effect of those free radicals.

Don’t like cherries? Red raspberries are another great source.



2. Drinking Coffee


Coffee makes everything better

The science: Multiple studies show that pre-workout caffeine consumption can reduce subsequent muscle soreness and fatigue. In one study published in the Journal of Pain, the strategy scored exercisers a 48 percent drop in DOMS.


3. Getting a Massage


Research from a 2014 study found that a post-exercise massage can significantly reduce pain. And over the long term, regularly getting massages may increase your body’s ability to fight off DOMS.

Schedule your sports massage directly following your workout. In the study, immediate massage was more effective at promoting tissue regeneration and reducing fibrosis compared to massage delayed 48 hours after exercise.


4. Foam Rolling


Similar to massage, foam rolling is all a relieving tension in the muscle’s connective tissue. Research has found that rolling out your muscles can help reduce delayed onset muscle soreness. It can also improve performance in subsequent workouts.

5. Performing Recovery Workouts


This may be one of the most effective methods. performing a 20-minute bout of low- or moderate-intensity cycling immediately following a high intensity workout can cause a reduction in muscle pain along with a added boost in strength.

Light recovery workouts increase blood flow, which in-turn naturally help the inflammatory process along, such as lymphatic draining, moving immune cells, and clearing inflammatory mediators.


So there are our top 5 tips to ease DOMS. On the other hand just suffer on for 48 hours after your session and you should be fine. It will be better the next time you do it.
