The accumulation of lactic acid in muscles during intense exercise is often associated with fatigue, but it is not the primary cause of delayed muscle soreness (DOMS) that occurs after overexertion. DOMS is primarily attributed to microscopic damage to muscle fibers and the subsequent inflammatory response, rather than lactic acid buildup. While lactic acid levels can rise during vigorous activity, they typically return to normal shortly after exercise, whereas muscle soreness can develop 24 to 48 hours post-exercise.
Lactic acid fermentation
The three symptoms of lactic acid build-up are muscle fatigue, muscle soreness, and muscle weakness.
It's lactic acid. C3H6O3

The three symptoms associated with lactic acid build up are muscle fatigue, muscle soreness, and muscle cramps.
A muscle injury is a tear or bruise of the muscle itself. Muscle soreness is more commonly the burning from lactic acid trapped in the muscles that is burned off with strenuous use of the muscle.
Lactic acid fermentation is a metabolic process in which glucose is converted into lactic acid. This anaerobic process is common in muscle cells during intense exercise when oxygen supply is limited, resulting in the accumulation of lactic acid which can cause temporary muscle fatigue and soreness. Lactic acid fermentation is also used in the production of certain foods like yogurt and sauerkraut.
The anaerobic energy system, specifically the lactic acid energy system, produces a fatiguing end result due to the accumulation of lactic acid in the muscles. This buildup can lead to muscle fatigue, soreness, and a decrease in performance.
Anaerobic respiration in muscle cells during strenuous exercise produces lactic acid as a byproduct. This buildup of lactic acid can cause muscle fatigue and soreness.
When muscles work hard, they produce lactic acid as a byproduct. The accumulation of lactic acid can lower the pH level in muscles, leading to fatigue. This can interfere with muscle contractions and reduce their ability to generate force, causing muscle fatigue.
Muscle fatigue is caused by an accumulation of lactic acid in muscles.
Lactic Acid forms in the muscles as a metabolic by-product of intense muscle use. The resultant lactic acid (CO2 Buildup) in the muscle causes a delayed onset muscle stiffness/soreness.
