Muscle fatigue is when muscles that were initially generating a normal amount of force, then experience a declining ability to generate force.

Exertional rhabdomyolysis, the exercise-induced muscle breakdown that results in muscle pain/soreness, is commonly diagnosed using the urine myoglobin test accompanied by high levels of creatine kinase (CK). Myoglobin is the protein released into the bloodstream when skeletal muscle is broken down.
The process of rhabdomyolysis also releases myoglobin into the blood, which will eventually end up in the urine and cause it to become red or brown: another condition known as myoglobinuria. [16] Some other common symptoms are exercise intolerance, which consists of fatigue, muscle pain, and cramps during exercise, and skin rashes.
The American TV show, Diagnosis, in episode 1 Detective Work, an athletic 23-year-old nursing student, Angel Parker, experiences episodes of extreme muscle fatigue, pain and cramping after prolonged exercise, sometimes followed by dark urine (myoglobinuria) and elevated CK (rhabdomyolysis). These episodes can leave her immobile for hours.
Delayed onset muscle soreness (DOMS) is the pain and stiffness felt in muscles after unaccustomed or strenuous exercise. The soreness is felt most strongly 24 to 72 hours after the exercise. [ 1 ][ 2 ]: 63 It is thought to be caused by eccentric (lengthening) exercise, which causes small-scale damage (microtrauma) to the muscle fibers.
Post-exertional malaise (PEM), sometimes referred to as post-exertional symptom exacerbation (PESE) [1] or post-exertional neuroimmune exhaustion (PENE), [2] is a worsening of symptoms that occurs after minimal exertion. It is the hallmark symptom of myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) and common in long COVID and ...
