The act of gaining endurance through physical activity has been shown to decrease anxiety, depression, and stress, or any chronic disease in total.[3] Although a greater endurance can assist the cardiovascular system it does not imply that any cardiovascular disease can be guaranteed to improve.[4] "The major metabolic consequences of the adaptations of muscle to endurance exercise are a slower utilization of muscle glycogen and blood glucose, a greater reliance on fat oxidation, and less lactate production during exercise of a given intensity."[5]
