Dear students, another physiological cause of muscle fatigue is the interruption in excitation contraction coupling. This happens due to impaired calcium release from cells internal resources that is from endoplasmic reticulum. This recovery is relatively slower and it takes 24 to 72 hours to recover. Dear students, the third cause of muscle fatigue is the interruption of blood flow to the contracting muscles. As a result, the nutrient and oxygen supply to the muscles is affected. This is the cause of the muscle contraction. We call the complete muscle fatigue as the complete muscle fatigue and it takes more time to recover. Dear students, apart from these three major causes, other fatigue contributors are the accumulation of inorganic phosphates in the muscles. Then, accumulation of hydrogen ions, which we call metabolic acidosis, which affect the metabolic processes of the cells and muscle cells. Apart from this, due to muscle-cell contraction, the cells have either the depletion of glycogen in the energy resources or the depletion of ATP. As a result, muscle fatigue appears. Dear students, in the past, the biggest contributor for muscle fatigue was the accumulation of lactic acid. However, recent research has proved that this factor is not a cause of muscle fatigue. Therefore, we do not understand this factor because of muscle fatigue.
