After such exercise, the muscle adapts rapidly to prevent muscle damage, and thereby soreness, if the exercise is repeated. [1] [2]: 76 Delayed onset muscle soreness is one symptom of exercise-induced muscle damage. The other is acute muscle soreness, which appears during and immediately after exercise.
Acute muscle soreness (AMS) is the pain felt in muscles during and immediately, up to 24 hours, after strenuous physical exercise. The pain appears within a minute of contracting the muscle and it will disappear within two or three minutes or up to several hours after relaxing it. [1] There are two causes of acute muscle soreness: [1]
This is known as compartment syndrome which leads to greater death of the surrounding muscle tissue around the injury. [14] As the muscle dies this will cause pain to radiate from the affected area into the compartmentalized tissue. A loss of range of motion from swelling will also be seen in the affected limb.
Sensory overload, [13] emotional distress, injury, sleep deprivation, infections, and spending too long standing or sitting up are other potential triggers. [6] The resulting symptoms are disproportionate to the triggering activity and are often debilitating, potentially rendering someone housebound or bedbound until they recover. [11] [6] [14] [4]
Myalgia or muscle pain is a painful sensation evolving from muscle tissue. It is a symptom of many diseases . The most common cause of acute myalgia is the overuse of a muscle or group of muscles ; another likely cause is viral infection , especially when there has been no injury .
Muscular lactic acid levels return to normal levels within an hour after exercise; delayed onset muscle soreness is thought to be due to microtrauma from unaccustomed or strenuous exercise. [282] Stretching before or after exercise does not reduce delayed onset muscle soreness. [283] Urine is not sterile, not even in the bladder. [284]
Immediate onset of symptoms includes physical impacts, such as dizziness, headache, anterograde or retrograde amnesia, loss of consciousness, vomiting and more. [1] Delayed onset of symptoms may occur a few hours or days after the injury. The delayed symptoms involve all the physical, emotional and cognitive changes.
This meaning implies that the primary defect is within the muscle, as opposed to the nerves ("neuropathies" or "neurogenic" disorders) or elsewhere (e.g., the brain). This muscular defect typically results in myalgia (muscle pain), muscle weakness (reduced muscle force), or premature muscle fatigue (initially normal, but declining muscle force).
