Every day, when puffing on the tape, focusing vigorously on keeping yourself lean, have you ever thought about what physically is happening in your body besides burning a lot of calories? For best results, the more people need to stop focusing solely on calorie burn, and start thinking about improving such fitness values as VO2 Max, or maximum oxygen consumption. What exactly is your VO2 Max? VO2 max is defined as the highest rate at which oxygen can be taken and used during high intensity exercise dynamics. When you are exercising in aerobic treadmill, every muscle contraction require oxygen to break down fats, carbohydrates and proteins, so that the supply of energy (ATP) needed to feed the muscles in order for movement to occur. feld listens, a sympathetic response will follow. Humans, at rest, need 3.5 ml of oxygen each minute for each kilogram of body weight to sustain cellular activity in the tissues that keep us alive. Now let's go back to our routine. As you increase the speed or incline (intensity), more oxygen is needed to transfer the oxygen through the blood and muscles. Due to the increased intensity during your exercise session, more oxygen is required to start the process of energy release.
