Delayed onset muscle soreness (DOMS) is a type of muscle pain that occurs 12–24 hours after strenuous exercise. It can cause stiffness, muscle tenderness, or severe pain. DOMS can affect people of all fitness levels, and is common when athletes return to training after a period of reduced activity or are first introduced to certain activities.
Read on to learn more about DOMS, including symptoms, causes, treatment, and more.
Difference between DOMS and Acute Muscle Soreness
Pain felt during or immediately after a workout is a different kind of muscle soreness. It’s called acute muscle soreness.
Acute muscle soreness is that burning sensation you feel in a muscle during a workout due to a quick buildup of the buildup of metabolites during intense exercise. It usually disappears as soon as or shortly after you stop exercising.
However, DOMS often begins much after your workout has finished. You won’t feel DOMS during a workout.
How to identify if you have DOMS
According to theAmerican College of Sports Medicine, DOMS symptoms typically occur up at least 12 to 24 hours after a workout. The pain tends to peak about one to three days after your workout, and then should ease up after that.
Symptoms of DOMS to watch out for may include:
pain when stretching muscles, leading them to become contracted and tight
muscles that feel tender to the touch
reduced range of motion due to pain and stiffness when moving
High-intensity exercisecan cause tiny, microscopic tears in your muscle fibers. Your body responds to this damage by increasing inflammation, which may lead to a delayed onset of soreness in the muscles.
Pretty much any high-intensity exercise can cause DOMS, but one kind in particular, known as eccentric exercise, often triggers it.
Eccentric exercises cause you to tense a muscle at the same time you lengthen it.
For example, the controlled, downward motion as you straighten your forearm after a biceps curl is an eccentric movement. The way your quads tense up when running downhill is also an eccentric movement.
Is there a connection between DOMS and lactic acid?
It was once thought that a buildup of exercise-induced lactic acid was to blame for DOMS, but this common misconception has been debunked.
Acute muscle soreness is due to lactic acid buildup. DOMS, on the other hand, is not related to lactic acid buildup; it’s due to microscopic tears and muscle damage.
Who can experience DOMS?
DOMS can affect just about anyone, from elite athletes, to beginners, to people who haven’t worked out in a long time.
So, no matter your level of fitness, DOMS may strike whenever you dial up your workout intensity, perform eccentric exercises, or try a new kind of exercise your body isn’t used to.
