Muscle soreness, scientifically known as delayed onset muscle soreness (DOMS), is a common discomfort that affects many people after physical exercise. Although it can appear in any muscle group, the legs are usually the most affected due to the load they bear during activities such as running, jumping, or performing resistance exercises.
This pain can range from mild discomfort to a sharp sensation that makes movement difficult, which can discourage many people from continuing their exercise routine. However, understanding why muscle soreness occurs and how to treat it effectively can make a difference in recovery and in maintaining an active and healthy lifestyle.
What is muscle soreness and why does it appear?
Muscle soreness, or delayed onset muscle soreness, is a phenomenon that generally occurs between 24 and 72 hours after performing intense or new physical activity for the body. This muscle pain is associated with microscopic damage to muscle fibers during exercise, especially in activities involving eccentric contractions, that is, when the muscle lengthens while contracting, such as lowering a weight or running downhill.
The body reacts to this muscle damage by sending inflammatory cells to the affected area, which causes swelling and pain. Although this process is a natural part of the body’s adaptation to exercise and, over time, helps strengthen muscles, it can be quite uncomfortable and discouraging, especially in the legs, which are essential for daily mobility.
The legs are particularly susceptible to muscle soreness due to the number of large muscles activated during most physical activities. From running and cycling to climbing stairs, the legs are in constant use and, when subjected to unusual effort, are more likely to experience this type of muscle pain.
Effective methods to relieve muscle soreness in the legs
There are several effective methods to ease this discomfort and speed up muscle recovery:
Adequate rest and active recovery
Rest is essential to allow the muscles to recover from the damage sustained during exercise. However, this does not mean you should remain inactive. Active recovery, which involves light exercises such as walking or gentle stretching, can help improve blood circulation and speed up the removal of metabolic waste responsible for the pain.
Hydration and nutrition
Water helps eliminate toxins and keeps muscle cells functioning properly. Additionally, a diet rich in proteins and complex carbohydrates can provide the necessary nutrients for muscle repair. Including foods high in antioxidants, such as fruits and vegetables, can also help reduce inflammation.
Massages and stretching
Massages help improve circulation and reduce muscle tension. Gentle stretching is also beneficial as it increases flexibility and can relieve muscle stiffness. It is important not to overstretch the muscles to avoid worsening the pain.
Use of creams and topical products
Anti-inflammatory creams and gels with ingredients like menthol often have a cooling or warming effect that can reduce the sensation of pain and improve comfort. However, it is important to use them as a complement to other recovery strategies and not as the sole solution.
Application of cold and heat
Applying cold within the first 24 to 48 hours after exercise can help reduce inflammation and pain. Later, applying heat can be beneficial to relax muscles and improve blood flow, which promotes recovery. Alternating between cold and heat can also be an effective strategy to relieve muscle soreness.
Common myths about muscle soreness
There are many myths surrounding muscle soreness, some of which can lead to ineffective or even harmful practices. Below, we debunk some of the most common:
Is lactic acid to blame?
For a long time, it was thought that muscle soreness was caused by the accumulation of lactic acid in the muscles. However, recent research has shown that lactic acid is cleared from the body shortly after exercise and is not responsible for muscle soreness. The pain is actually due to microtears in the muscle fibers.
Does drinking sugar water help?
A popular tip is to drink sugar water to relieve muscle soreness, but there is no scientific evidence supporting this practice. The key is hydration and a balanced diet, not excessive sugar consumption.
Is it better to keep exercising despite the pain?
While staying active is important, pushing the body to perform intense exercise while suffering from muscle soreness can worsen muscle damage. It is better to opt for active recovery and low-intensity exercises until the pain decreases.
How to prevent muscle soreness in the legs
The best way to deal with muscle soreness is to prevent it. Here are some effective strategies to minimize its occurrence:
Proper warm-up
A good warm-up before exercising prepares the muscles for physical effort and reduces the likelihood of muscle soreness. Include dynamic exercises that engage the muscles you will work, such as light squats or leg swings.
Gradual progression in exercise intensity
Avoiding sudden increases in exercise intensity or duration is key to preventing muscle soreness. Gradually increase effort, allowing your body to adapt to the new level of demand.
Post-exercise cool-down techniques
After training, it is important to perform an adequate cool-down. This can include static stretching or a gentle walk to help muscles return to their normal state and reduce stiffness.
