Lactic acid causes muscle fatigue because it accumulates in muscles during intense exercise, leading to a decrease in pH levels. This decrease in pH interferes with muscle contractions and energy production, ultimately causing the muscles to feel tired and fatigued.

Does lactic acid cause fatigue during physical activity?

Yes, lactic acid can contribute to fatigue during physical activity. When the body breaks down glucose for energy without enough oxygen, lactic acid is produced. This buildup of lactic acid can lead to muscle fatigue and discomfort.


What process leaves lactic acid in your body?

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.


Muscle fatigue occurs due to accumulation of?

carbon dioxide


What chemical is in high concentration in a fatigue muscle?

Lactic acid is in high concentration in a fatigued muscle. It is produced during anaerobic metabolism when the oxygen supply is limited, leading to an accumulation of lactic acid in the muscle tissue, contributing to the sensation of fatigue.


Muscle fatigue is caused by a buildup of?

Muscle fatigue is caused by an accumulation of lactic acid in muscles.


How does the accumulation of lactic acid in muscles contribute to the development of muscle fatigue?

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.


What are the three symptoms of lactic acid build-up?

The three symptoms of lactic acid build-up are muscle fatigue, muscle soreness, and muscle weakness.


Lactic acid in your muscle cells make them what?

Lactic acid in muscle cells can cause them to feel fatigued and sore. When produced during intense exercise, lactic acid can build up and contribute to muscle fatigue and discomfort. However, lactic acid can also be used as an energy source by the body under certain conditions.
