Muscle soreness is a common occurrence, especially after physical activity or exercise. While it is usually temporary and not serious, it can sometimes be a symptom of muscle damage. This sensation is known as Delayed Onset Muscle Soreness (DOMS) and is characterised by pain and stiffness in the muscles after strenuous exercise. DOMS is associated with microscopic tears and muscle damage, but the magnitude of soreness does not always reflect the extent of muscle damage.

What You'll Learn

Muscle soreness and serious injury
Firstly, muscle soreness typically occurs after exercise and is often a result of delayed onset muscle soreness (DOMS). DOMS usually develops 12-48 hours after exercise and can last for up to five days. It is caused by micro-tears in the muscle fibres, which trigger an inflammatory response as the body works to repair the trauma. This results in swelling and soreness, indicating that the body is rebuilding muscle fibres to become stronger. DOMS typically improves with movement and is not a cause for concern.
On the other hand, a serious muscle injury may be indicated by sharp, noticeable pain that affects your mobility. Strains, for example, occur when a muscle or tendon is torn or damaged and often cause intense pain, muscle spasms, swelling, and difficulty moving the affected muscle. If you experience these symptoms, it is advisable to seek medical attention.
According to Dr. Scott Rand, a sports medicine doctor, the key distinction is whether the pain is "earned" or not. If the pain is a result of a challenging workout and it dissipates over time, it is likely muscle soreness. However, if the pain is unexpected and affects your mobility, it may indicate a more serious injury that requires medical evaluation.
Additionally, the location and persistence of the pain can be indicative of a serious injury. For example, adolescents who experience sharp pain in the elbow or front of the shoulder during a throwing motion may have a growth plate injury, which can cause long-term damage if left untreated.
In summary, while muscle soreness and serious injury can have some overlapping symptoms, distinguishing between the two requires understanding the context, intensity, and persistence of the pain, as well as any associated loss of mobility. If you are unsure, it is always best to consult a healthcare professional for a proper diagnosis and treatment plan.

DOMS and muscle-building
Delayed Onset Muscle Soreness, or DOMS, is the muscle soreness that you feel the day after an intense workout, a new exercise, or if you're a beginner. It can develop as early as 6 to 12 hours after your workout and may last for as long as three to five days, peaking around 48 hours. DOMS is caused by a type 1 muscle strain, which is some degree of fibre damage, but nothing too serious.
DOMS is correlated with exercise-induced muscle damage to some degree, but it is not an accurate indicator of muscle damage. While soreness can provide some insight, it should not be used as a marker for a good workout. High levels of soreness indicate that the muscle's capacity for repair has been exceeded, which can impede the ability to train properly and decrease motivation.
There are several theories that try to explain what causes DOMS. One of them is the enzyme influx theory, which suggests that extra calcium is stored within damaged muscles after exercise and triggers the release of various enzymes that signal muscle breakdown, resulting in inflammation and pain. Another theory is the muscle damage theory, which states that during weight training, muscle damage occurs and the structure is rearranged.
To decrease the risk of DOMS, it is recommended to slowly progress into a new exercise program. This allows the muscle time to acclimate to a new movement and leaves room for more adaptation. While a proper warm-up is always suggested, neither warming up nor stretching before exercise has been shown to reduce or prevent DOMS. Foam rolling has only been shown to improve DOMS in some studies.
While DOMS is not necessary for muscle growth, muscle damage is a contributing factor to muscle hypertrophy, though not a necessary one. However, extreme muscle soreness can be counterproductive, as it can decrease force-producing capacity and motivation levels, which will be detrimental to performance in subsequent workouts.

Muscle soreness and recovery
During exercise, muscles undergo micro-tears, resulting in inflammation and the release of blood, which irritates the muscles and causes spasms and soreness. This process is essential for muscle growth and repair, making soreness a positive indicator of muscle adaptation. However, it is important to note that soreness does not always indicate muscle growth, and the correlation between muscle damage and growth is poor.
The intensity and duration of muscle soreness can vary depending on the type of exercise, with activities like weight lifting, jogging, and hill running commonly causing DOMS. Soreness usually peaks a day or two after exercise and gradually subsides within a few days. It is characterized by a tight, aching feeling that typically improves with movement and does not affect mobility.
To differentiate between soreness and injury, it is important to consider the nature and persistence of the pain. Injury pain may be sharp and immediate, indicating a potential strain or sprain. Additionally, pain that persists for more than a couple of weeks or worsens with rest may be a sign of a more serious issue requiring medical attention.
Proper recovery techniques are essential for managing muscle soreness and preventing injuries. These include rest, hydration, proper nutrition, stretching before and after workouts, and gradually increasing exercise intensity. Alternating between different types of activities and allowing for rest days can also help manage soreness and improve recovery.

Muscle pain and inflammation
Muscle soreness is a common occurrence after physical activity, especially after trying a new workout or exercise. This is known as delayed onset muscle soreness (DOMS) and can develop as early as 12 hours after your workout, lasting for up to three to five days. It is caused by micro-tears in the muscle fibres, which trigger an inflammatory response as the body works to repair the trauma. This results in swelling and soreness, indicating that the body is rebuilding muscle fibres to become stronger and more resilient.
While muscle soreness is typically temporary and improves with rest and home care, it is important to distinguish it from pain that may indicate a more serious injury. Acute injuries, such as pulled muscles or sprained ankles, can occur suddenly after an awkward movement or exercising with poor form. Chronic or overuse injuries, such as patellar tendonitis or plantar fasciitis, develop gradually due to frequent, repetitive movements.
To differentiate between soreness and injury pain, it is important to consider the intensity and persistence of the pain. Soreness usually presents as a tight, aching feeling that improves with movement and typically lasts only a few days. On the other hand, injury pain may be sharp and persistent, affecting your mobility and range of motion. If the pain does not dissipate within one to two weeks or worsens despite rest, it is recommended to consult a healthcare professional for evaluation and treatment.
Additionally, certain medical conditions can cause muscle pain without necessarily damaging the muscles. For example, fibromyalgia and chronic fatigue syndrome can lead to musculoskeletal pain, while hypothyroidism, vitamin D deficiency, and electrolyte imbalances can disrupt normal muscle function, resulting in pain.
While muscle soreness is generally not a cause for concern, it is always important to listen to your body and seek medical advice if you are concerned or if your symptoms persist or worsen.

Muscle soreness and progression
Muscle soreness is a common occurrence after a workout, especially after trying something new or challenging. This soreness is usually temporary and goes away on its own, but it can be uncomfortable and affect your mobility. While it may be a sign of muscle damage on a microscopic level, this damage is typically not harmful and is even considered part of the muscle-building process. In fact, muscle damage is one of the three main mechanisms of muscle growth, with research showing that muscle growth can still occur without it.
Delayed onset muscle soreness (DOMS) typically occurs 12 to 48 hours after exercise and can last for up to five days. It is caused by micro-tears in the muscle fibres, triggering an inflammatory response as your body repairs and strengthens these fibres. The harder the workout, the more muscle damage and soreness you may experience. However, the correlation between muscle damage and muscle growth is poor, and some muscle groups do not experience soreness to the same degree as others.
Progression in your exercises over time is what guarantees hypertrophy and increased muscle damage, regardless of whether soreness occurs. If you are getting too sore, you can lower the volume or intensity of your workouts and gradually increase the challenge. Alternating activities, such as exercising different muscle groups on different days, is important to give your muscles adequate time to recover. Proper warm-ups, stretching, rest, hydration, and nutrition also play key roles in helping your muscles recover and avoiding injury.
While muscle soreness is typically not a cause for concern, sharp and persistent pain that affects your mobility or persists beyond a few days may indicate a more serious injury that requires medical attention. It is important to listen to your body and learn what feels normal versus abnormal in terms of exercise-related soreness and pain. If you are unsure, a medical professional can provide a definite diagnosis and treatment plan.

Frequently asked questions
Muscle soreness is not always indicative of muscle damage. It is common to experience muscle soreness after physical activity or due to infections, and this usually improves with rest. However, muscle soreness can also be a symptom of muscle damage, especially if it persists or worsens despite rest. In such cases, it is advisable to seek professional medical advice.
DOMS stands for Delayed Onset Muscle Soreness. It is the pain and stiffness felt in muscles after strenuous exercise, typically peaking 1-3 days after the workout. DOMS is associated with microscopic tears and muscle damage, but the magnitude of soreness does not necessarily reflect the extent of muscle damage.
There are various treatments for DOMS, including rest, low-intensity activity, massage, nerve mobilization, hot baths, and topical analgesics. Some athletes also use cold water baths or whole-body cryotherapy, although evidence for their effectiveness is limited.
While muscle soreness is not a direct indicator of muscle growth, there may be an optimal level of soreness that suggests muscle damage without hindering recovery. Muscle damage is one of the mechanisms of muscle growth, but it is not required for growth to occur. Progression in weight and reps over time is more critical for long-term muscle growth.
