Dominic Stone
Delayed Onset Muscle Soreness (DOMS) is a common condition that causes muscle pain and stiffness after strenuous or unusual physical activity. It is characterised by a dull, aching pain and tenderness in the affected muscles, which typically peaks within 24 to 72 hours post-activity and resolves within 4 days. While the exact mechanism of DOMS is not fully understood, it is believed to result from microscopic tears and inflammation in the muscle fibres. This inflammation can lead to increased levels of histamines, prostaglandins, and potassium, causing pain. Although DOMS is typically not a cause for concern, it is important to differentiate it from other types of pain, such as rhabdomyolysis, which may require immediate medical attention.

Delayed onset muscle soreness (DOMS) is caused by eccentric exercises
Delayed onset muscle soreness (DOMS) is a common phenomenon experienced by many people who engage in physical activity. It is characterised by muscle pain and stiffness that typically occurs after strenuous or unusual physical activity. This soreness is the result of temporary micro-damage and inflammation in the muscle tissue. While DOMS can be caused by various types of exercises, it is particularly associated with eccentric exercises.
Eccentric exercises involve muscle lengthening, where an individual tenses a muscle while simultaneously lengthening it. Examples of eccentric movements include the controlled downward motion when straightening the forearm after a bicep curl or the way the quadriceps tense up while running downhill. Eccentric exercises create increased tension per unit area, resulting in greater injury to the tissue. This increased tension can cause the actin and myosin cross-bridges to separate before relaxation, leading to increased tension on the remaining active motor units.
The micro-damage caused by eccentric exercises is known as microtrauma, which is mechanical damage at a very small scale. This microtrauma stimulates nociceptors (pain receptors) within the muscle's connective tissues, resulting in the sensation of pain. Additionally, the enzyme efflux theory suggests that after microtrauma, calcium accumulates in the damaged muscles, inhibiting cellular respiration and leading to the breakdown of muscle protein.
While the mechanism of DOMS is not fully understood, it is believed that the soreness is a result of the body's inflammatory response to the microtrauma. This response may induce secondary damage, causing further pain and discomfort. It is important to note that the severity of DOMS is not always indicative of the extent of muscle damage. Implementing recovery strategies, such as massages, heat packs, and pain relievers, can help manage symptoms and aid in restoring muscular strength and performance.
In summary, delayed onset muscle soreness (DOMS) is often caused by eccentric exercises that create increased tension and lead to micro-damage in the muscle fibres. This micro-damage triggers an inflammatory response in the body, resulting in the pain and stiffness associated with DOMS. Understanding the relationship between eccentric exercises and DOMS can help individuals manage their recovery process effectively.

DOMS is a type of muscle pain that peaks 1-3 days after strenuous physical activity
Delayed Onset Muscle Soreness (DOMS) is a type of muscle pain that typically starts 12 to 24 hours after strenuous physical activity and peaks in intensity between 24 to 72 hours. It is characterised by muscle stiffness, tenderness, tightness, and a dull, aching pain. DOMS is thought to be caused by eccentric exercises, which involve muscle lengthening and generate greater tension per unit area, leading to microscopic tears and damage to muscle fibres. This damage triggers an inflammatory response, resulting in secondary damage and pain. While the underlying mechanisms are not fully understood, neural, mechanical, and cellular adaptations are proposed to play a role in reducing soreness.
The severity of DOMS is unrelated to the extent of exercise-induced muscle damage, and anyone can experience it regardless of their fitness level. Any physical activity that stresses the muscles can cause DOMS, including weightlifting, high-intensity training, or even everyday activities like carrying heavy boxes or home decorating. The pain typically occurs when the muscle is stretched, contracted, or under pressure, rather than at rest.
DOMS is often referred to as "muscle fever," but it is important to differentiate it from other types of pain. A rare but serious condition called rhabdomyolysis can develop days after intense exercise, causing sharp pain, muscle spasms, and numbness. If you experience these symptoms, seek immediate medical attention.
To manage DOMS symptoms, various recovery strategies can be employed, such as massages, heat packs, pain relievers, and cold-water immersion. Implementing these strategies is crucial for preventing and managing DOMS, as well as restoring muscular strength and performance levels. Additionally, gradually increasing the intensity of a new exercise programme can help reduce soreness by taking advantage of the repeated-bout effect.
While DOMS typically resolves within 4 days, it is important to listen to your body and adjust your exercise routine as needed. Proper recovery techniques and progressive exercise programmes are key to minimising soreness and maximising muscular health.

DOMS is not related to the extent of exercise-induced muscle damage
Delayed Onset Muscle Soreness (DOMS) is a type of muscle pain that occurs after strenuous or unusual physical activity. It is characterised by muscle stiffness, tightness, tenderness, and soreness. DOMS typically starts 12 to 24 hours after a workout and peaks around 24 to 72 hours post-exercise.
While DOMS is associated with exercise-induced muscle damage, the severity of soreness is not indicative of the extent of muscle damage. In other words, the intensity of the pain does not directly correlate with the amount of muscle injury. This notion challenges the traditional understanding of DOMS, which attributed the pain to the accumulation of lactic acid in the blood. However, this theory has been largely rejected, as concentric contractions, which produce lactic acid, do not cause DOMS. Furthermore, lactic acid levels return to normal within an hour of exercise, which cannot explain the delayed onset of pain.
The pain associated with DOMS is now believed to result from microscopic tears and temporary microtrauma to the muscle fibres. Eccentric exercises, which involve muscle lengthening, are particularly implicated in causing DOMS. During these exercises, the increased tension force on the muscle fibres can lead to broadening, smearing, and damage to the sarcomere. This microtrauma stimulates nociceptors (pain receptors) within the muscle's connective tissues, resulting in the sensation of pain.
It is important to differentiate DOMS-related muscle soreness from other types of pain. While DOMS is typically characterised by a dull, aching pain, conditions such as rhabdomyolysis can cause sharp pain, muscle spasms, and numbness. Rhabdomyolysis occurs when skeletal muscle fibres break down and enter the bloodstream, requiring immediate medical attention. Therefore, while DOMS may cause significant discomfort, it is generally not indicative of severe muscle damage.
Additionally, the pain-free period before the onset of DOMS suggests that the condition is not solely due to muscle disruptions but has other underlying causes. The secondary injury model proposes that the inflammatory response following the initial muscle damage can induce secondary trauma. This response involves the activation of neutrophils and pro-inflammatory macrophages, which, in excess, can cause collateral damage to healthy cells.

DOMS is a type 1 muscle strain injury
Delayed Onset Muscle Soreness (DOMS) is muscle pain and stiffness, or "muscle fever", that occurs after strenuous or unusual physical activity. It is a type 1 muscle strain injury, with a pain-free period of 12 to 24 hours and peak soreness between 24 to 72 hours. DOMS is thought to result from temporary microtears and inflammation in muscle tissue, commonly triggered by eccentric exercises. Eccentric exercises cause you to tense a muscle at the same time you lengthen it, such as the controlled, downward motion as you straighten your forearm after a bicep curl.
The pain associated with DOMS is caused by microtrauma, or mechanical damage at a very small scale, to the muscles being exercised. This microtrauma stimulates nociceptors (pain receptors) within the muscle's connective tissues, causing a sensation of pain. The severity of DOMS symptoms correlates with the intensity and duration of the activity. The soreness increases to a peak between 24 and 72 hours, then subsides by 7 days.
While the mechanism of DOMS is not completely understood, there are several theories that attempt to explain it. One theory, the "enzyme efflux" theory, suggests that following microtrauma, calcium that is normally stored in the sarcoplasmic reticulum accumulates in the damaged muscles. This accumulation of calcium may activate proteases and phospholipases, which break down and degenerate muscle protein. Another theory is the secondary injury model, which proposes that after the initial trauma (muscle damage or injury), the inflammatory cascade that follows can induce secondary damage.
DOMS is typically resolved within 7 days without any specific treatment. However, there are several recovery strategies that can help manage symptoms, such as massages, heat packs, and pain relievers. Implementing these strategies is important for preventing and managing DOMS, as well as recovering from Exercise-induced muscle damage (EIMD), which are key for restoring muscular strength and performance levels.

DOMS can be prevented by gradually increasing the intensity of a new exercise program
Delayed Onset Muscle Soreness (DOMS) is a common physical response to intense or unfamiliar exercise. It is characterised by muscle pain, stiffness, and tenderness, which typically starts within 12 to 24 hours after a workout and peaks about one to three days later. DOMS is thought to be caused by microscopic tears and inflammation in muscle fibres, particularly following eccentric exercises, which involve muscle lengthening.
While it may not be possible to completely prevent DOMS, gradually increasing the intensity of a new exercise program can help reduce its likelihood and severity. This approach, known as progressive overload, allows the body to adapt and build resilience. For example, starting with eccentric exercises performed at 40% of maximal strength can provide protection from muscle damage when progressing to higher-intensity exercises later on.
Additionally, incorporating physical activity before eccentric exercises can help prevent DOMS. This includes dynamic stretching and warming up the muscles before a workout. Static stretching after a workout may also aid in recovery, but it is not a preventive measure for soreness.
Other strategies to prevent and manage DOMS include massage, self-myofascial release techniques, and full-body immersion in cold water, which can improve muscle recovery and blood flow. Proper hydration before, during, and after exercise in hot and humid temperatures can also reduce muscle soreness.
It is important to note that DOMS is typically a normal response to a new exercise program and usually resolves within a few days. However, if the pain is severe, sharp, or persistent, it is recommended to consult a doctor or physical therapist for further guidance and treatment options.

Frequently asked questions
Delayed Onset Muscle Soreness (DOMS) is muscle pain and stiffness, or "muscle fever", that occurs after strenuous or unusual physical activity.
DOMS is caused by eccentric exercise, which involves eccentric (lengthening) contractions of the muscle. This causes small-scale damage (microtrauma) to the muscle fibres.
Symptoms of DOMS include muscular aches, reduced range of motion, swelling, and a reduction in muscle strength. DOMS typically begins the day after physical activity and peaks in soreness around 48 hours later, lasting no longer than 72 hours.
DOMS can be treated with massages, heat packs, pain relievers, and antioxidants. Implementing recovery strategies after exercises that cause DOMS is vital to prevent and manage symptoms.
While DOMS is sometimes referred to as "muscle fever", it does not cause a fever. DOMS is characterised by muscle pain and stiffness, reduced range of motion, and swelling, but it does not include a fever.
