Muscle fatigue is a feeling of tiredness or exhaustion that occurs after repeated muscle contractions or physical activity.
It is a normal response to exercise and is typically caused by the build-up of lactic acid in the muscles. Lactic acid is a byproduct of anaerobic metabolism, which occurs when the body’s demand for energy exceeds the oxygen supply to the muscles.
This can cause the muscles to become tired and fatigued. There are several factors that can contribute to muscle fatigue, including the intensity and duration of the exercise, the type of muscle fibers being used, and the overall condition of the muscles.
To help prevent muscle fatigue, it is important to warm up before exercise, stretch properly, and maintain proper hydration and nutrition.
