Your muscles produce more energy when you exercise, and the circulatory system's activity during exercise enhances the supply of fluids, oxygen and nutrients your muscles need for energy production. Exercising also increases your body's rate of various chemical reactions.The circulatory system works hard in helping your body to balance and maintain healthy chemical concentrations during exercise. Regular physical activity helps increase the efficiency of the circulation system's activity during exercise.orking muscles becomes your circulatory systemâs top priority during exercise.
