Lactic acid is a useless by-product of high-intensity exercise.

Question

Quizplus · Accepted Answer

Lactic acid is not a useless by-product. It actually serves as a fuel for the body during low-intensity exercise and can be converted back into energy by the liver. It also helps to buffer the build-up of hydrogen ions in muscles during high-intensity exercise, delaying muscle fatigue. However, it is true that too much lactic acid build-up can lead to muscle soreness and fatigue.
