The science behind muscle soreness and recovery

BBrandon September 19, 2023 7:01 AM

We've all been there: the day after an intense workout, you wake up feeling stiff and sore. But what's really going on in your muscles when you feel this way? And more importantly, how can you speed up your recovery? Let's dive deep into the science behind muscle soreness and recovery.

What causes muscle soreness?

The main cause of muscle soreness after a workout is a phenomenon known as Delayed Onset Muscle Soreness (DOMS). This occurs when you perform exercises that your body isn't used to, causing microscopic damage to your muscle fibers. This damage prompts an inflammatory response, which can lead to swelling and pain.

It's a common myth that lactic acid buildup is the cause of muscle soreness. While lactic acid does accumulate during intense exercise, it's usually cleared from your system within a couple of hours of your workout.

How to recover from muscle soreness

There are several strategies for recovering from muscle soreness. Here are a few that are backed by science:

  • Active recovery: Light activity like walking or cycling can help to increase blood flow to sore muscles, promoting recovery.

  • Stretching: Though it won't prevent DOMS, gentle stretching can temporarily alleviate muscle soreness.

  • Hydration and nutrition: Drinking plenty of water and eating a balanced diet rich in protein can aid in muscle recovery. Some studies also suggest that certain supplements, like creatine and BCAAs, can help.

  • Sleep: Sleep plays a crucial role in muscle recovery. During sleep, your body produces growth hormone, which helps to repair and rebuild muscles.

How long does muscle soreness last?

Typically, muscle soreness peaks 24 to 72 hours after a workout. How long it lasts can vary depending on several factors, including your fitness level and the intensity of your workout. However, it should gradually decrease and disappear within about a week.

The role of workout intensity

One important factor in both muscle soreness and recovery is the intensity of your workout. High-intensity workouts can lead to more DOMS, but they can also stimulate greater muscle growth and adaptation. The key is to listen to your body and not push beyond your limits.

The bottom line

Muscle soreness and recovery are complex topics, with many factors at play. While some soreness after a workout is normal and can even be a sign of muscle growth, it's important to take care of your body and allow it time to recover. By understanding the science behind muscle soreness and recovery, you can make more informed decisions about your workout routine and recovery strategies.
