1. When you exercise, your muscles demand more oxygen in order to metabolize energy. Your muscles also must have a medium to transfer the poisonous carbon dioxide that is a byproduct of the energy metabolism. The muscles rely on the bloodstream to carry out these tasks and therefore require a greater flow of blood. Blood is pumped to the muscles by the heart, stimulated by chemicals that muscles use during exercise to signal their new energy requirements. The chemicals the muscles use at this point automatically trigger a higher blood flow. The higher blood flow, however, has to get to the muscles, and this happens from the heart’s pumping mechanism. It is the heart’s pumping mechanism that realizes an increasing pace during exercise. That quicker pumping mechanism is what constitutes a higher blood pressure during exercise.
2. Your body requires a constant supply of blood glucose to function properly. To maintain an adequate level of blood sugar, your body stores glucose as glycogen in your liver and skeletal muscles. During strenuous exercise, your body uses these stores to provide critical energy, resulting in a decrease in glycogen during exercise. Because glycogen levels are depleted during both anaerobic and aerobic exercise, your body requires a recovery period to return to normal levels. Glycogen synthesis is greatest during a two-hour window immediately after your workout. During this period, consuming simple carbohydrates can dramatically raise your glycogen levels. After two hours, your body replenishes glycogen at a rate of roughly 2 percent an hour.
