The burning sensation in a runner's muscles when lactate builds up is primarily due to the accumulation of lactic acid, which is produced during anaerobic metabolism when the body needs energy quickly and oxygen supply is limited. As lactate levels increase, it can lower the pH in the muscle cells, leading to acidosis. This acidic environment can stimulate nerve endings, resulting in the characteristic burning feeling. Additionally, the buildup of lactate indicates that the muscles are working at high intensity, surpassing their aerobic capacity.

The burning sensation in a runner's muscles during lactate buildup is primarily due to the accumulation of hydrogen ions (H+) that accompany the production of lactate during anaerobic metabolism. As the intensity of exercise increases, the body relies more on anaerobic pathways for energy, leading to an increase in lactate and hydrogen ions. This decrease in pH within the muscle cells can irritate nerve endings, resulting in the characteristic burning feeling. Additionally, the shift in pH can impair muscle function, contributing to fatigue.

Lactic acid will build up. That causes a burning sensation.
