Detailed explanation-1: -Exercising muscles need more blood. And in response to regular exercise, they actually grow more blood vessels by expanding the network of capillaries. In turn, muscle cells boost levels of the enzymes that allow them to use oxygen to generate energy.
Detailed explanation-2: -Research published in the Journal of Atherosclerosis and Thrombosis shows that several hour-long, low intensity cardio workouts per week can increase capillary density by more than 25 percent.
Detailed explanation-3: -The potential of endurance training to increase skeletal muscle capillarisation has been known for a long time, with the first study in humans conducted by Andersen & Henriksson (1977). The study showed that capillary density was increased by 8 weeks of endurance training in previously sedentary males.
