T. Colin Campbell: Well, I mean really it should be a diet that is largely focused on plant-based foods, by that I mean vegetables and grains and fruits and legumes, of course, and in particular, sort of whole foods. I mean, we ought not to be taking (laughs), I mean plant foods are really the optimal diet.
Your working muscles can take oxygen out of the blood three times as well as your resting muscles. Your body has several ways to increase the flow of oxygen-rich blood to working muscle: 1  increased local blood flow to the working muscle. 2  diversion of blood flow from nonessential organs to the working muscle.3  increased flow of blood from the heart (cardiac output).our body has several ways to increase the flow of oxygen-rich blood to working muscle: 1  increased local blood flow to the working muscle. 2  diversion of blood flow from nonessential organs to the working muscle. 3  increased flow of blood from the heart (cardiac output).
Active muscles demand huge amounts of oxygen, and the circulatory system works hard to provide it. Blood carries oxygen to the muscles. When the body is at rest, blood carries nutrients to the muscles so that they can repair and rebuild themselves.he healthier and more active the muscle system, the healthier the circulatory system. When we move, the pump of our muscles prompts blood to return to the heart through the veins. Regular exercise increases both the strength and size of the heart. It also clears fatty deposits out of blood vessels.
