During strenuous exercise, lactic acid or 2-hydroxypropanoic acid is formed. Lactic acid buildup occurs during strenuous exercise, the body is incapable of removing the waste product from the muscle tissue. When lactic acid buildups it creates a burning sensation, however over recent years and studies, scientists have been doing more research on the acid and believe that is actually doesn't cause or increase muscle soreness but rather is an important fuel source for active muscles. But, more research is needed in this particular field for more definitive proof and information to be discovered.

Lactic acid is produced by our muscles during exercise.

The burning pain in our muscles during strenuous exercise is caused by the buildup of lactic acid, a byproduct of the body's energy production process when oxygen levels are low. This buildup can lead to muscle fatigue and discomfort.

The two substances that may be formed in anaerobic respiration are lactic acid and ethanol. Lactic acid is produced in the muscles during strenuous exercise, while ethanol is produced by yeast during fermentation.
During and after strenuous exercise, a student-athlete's heart beats quickly to pump more oxygen-rich blood to the muscles and organs that need it. This helps the body meet the increased demand for energy and oxygen during physical activity.
It's not unless you do things too strenuous. Exercise is encouraged.
Excess pyruvic acid is produced during prolonged strenuous exercise because the body relies more heavily on anaerobic respiration due to the insufficient supply of oxygen to meet energy demands. This causes an accumulation of pyruvate, the end product of glycolysis, which is then converted to lactic acid in order to regenerate NAD+ for continued ATP production.
Because the blood is diverted to the working muscles instead, as they need the more blood in order to provide oxygen for aerobic respiration
Strenuous activity causes the heart to beat faster because the body needs more oxygen and nutrients during physical exertion. The heart pumps faster to deliver these essential resources to the muscles and organs working hard during exercise.
The muscles continue to get enough energy during high levels of activity when there is not enough oxygen through the absorption of water. It is a good idea to drink water frequently when doing strenuous exercise.
