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).
When you work out, your muscles move from a resting state to an active one, and they need more oxygen to do their work. Your body accomplishes this by forcing more oxygen-rich blood to flow through your body. During exercise, your breathing rate increases, and you also take in more air with each individual breath.our lungs take in that increased oxygen, which mixes with your blood, and then goes to your heart, a highly effective pump that delivers blood to the rest of your body. Your body produces more heat during exercise as well. An increase in blood flow also allows the skin to dissipate heat more effectively.
