the muscles produce lactic acid which then relieves the muscles but it results in muscle cramps
During exercise, changes in insulin concentration can affect glucose mobilization by stimulating glucose uptake in muscles. When insulin levels decrease during fasting or intense exercise, there is reduced inhibition of glycogen breakdown and increased release of glucose from the liver to maintain blood glucose levels. Conversely, high insulin levels during rest or fed state promote glucose uptake by tissues, decreasing reliance on liver glucose release.
The blood glucose is used by the muscles during exercise. The level of the glucose in the blood drops down. This stimulates the secretion of the hormone called as glucagon. This glucagon is secreted by the alpha cells of the endocrine part of the pancreas.
mechanical energy
During exercise the body depletes its glucose reserves and blood sugar levels fall.
During high intensity exercise, muscles primarily get their energy from stored glycogen in the muscles and glucose in the bloodstream.
glucose is changed into pyruvate
glucose is changed into pyruvate
glucose is formed in the form of ATP

During gentle or moderate exercise, the products of cellular respiration of glucose are carbon dioxide and water (CO2 + H2O), just as in other cells.But if the exercise is vigorous, the muscle cells can switch to anaerobic cellular respiration (fermentation), in which case they convert each molecule of glucose into two of lactic acid.Later, most of the lactic acid is converted back to glucose.
