What is one explanation for sore muscles after a 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.

What is the science behind sore muscles?

“Small microscopic tears occur in the muscle,” he says. The mild muscle strain injury creates microscopic damage to the muscle fibers. Scientists believe this damage, coupled with the inflammation that accompanies these tears, causes the pain.

What are two causes of muscle soreness after exercise?

Microscopic tears in the muscle, or a breakdown in muscle tissue, likely causes DOMS after a workout. Trying a new type of exercise or increasing the intensity can increase how sore you are in the days following a workout. Over time, though, your muscles become resilient to that exercise.

Does being sore after a workout mean your muscles are growing?

If your muscles ache after a tough workout, you’re not alone. The classic next-day burn known as delayed onset muscle soreness (DOMS) happens to almost everyone, even the most conditioned athletes. In most cases, it’s a perfectly normal sign that your muscles are growing stronger.

Should I work out while sore?

In most cases, gentle recovery exercises like walking or swimming are safe if you’re sore after working out. They may even be beneficial and help you recover faster. But it’s important to rest if you’re experiencing symptoms of fatigue or are in pain.

Is being sore after a workout good?

The good news is that normal muscle soreness is a sign that you’re getting stronger, and is nothing to be alarmed about. During exercise, you stress your muscles and the fibers begin to break down. As the fibers repair themselves, they become larger and stronger than they were before.

What causes muscle soreness after a workout?

What causes muscle soreness? Aching muscles after a workout, otherwise known as delayed onset muscle soreness (DOMS), are due to micro-tears in your muscles that occur when you put stress on them, says Schoenfeld.

What is DOMS (delayed onset muscle soreness)?

It is commonly called Delayed Onset Muscle Soreness, or DOMS, and it is completely normal. DOMS usually begins within 6-8 hours after a new activity or a change in activity, and can last up to 24-48 hours after the exercise.

Should you workout when you’re sore?

A postworkout massage or foam rolling to relieve sore muscles help, too, according to Schoenfeld. But if you are ridiculously sore, Schoenfeld cautions you to not work out until your muscles feel a bit better, since you could risk an injury (a larger tear).

Why do my muscles tear when I exercise?

In other words, a lack of a certain activity in your routine leads to more muscle micro-tears when you finally do it. (But your muscles will get used to the activity over time and won’t tear as much anymore.) Overtraining can have the same effect. “If you really overdid it, you could be sore for up to a week,” Schoenfeld says.
