VO2 (volume of oxygen) testing may be defined as discovering the maximum amount of oxygen consumed by the body at near maximal or exhaustive exercise. This highly sought after testing protocol is deemed the absolute best indicator of cardiorespiratory endurance as well as a suitable insurance policy for fitness enthusiasts to burn more fat during cardiorespiratory workouts.
The two most valuable pieces of data an individual can receive from participating in a VO2 test are the particular point during performance which the onset of CO2 and blood lactate accumulation exceed the body’s ability to remove it (anaerobic threshold) and, whether the body is using carbohydrate or fat as a predominant fuel source at that particular time (substrate utilization). Through proper training we can teach the body to use higher percentages of fat at higher intensities. This will allow the body to preserve stored sugar, which may be a preferable source of fuel as intensities rise.
RMR (resting metabolic rate) may be defined as the maximum amount of oxygen (O2) consumed by the body at rest. Since there is a direct correlation between O2 and calories (energy), this allows the specialist to determine the appropriate amount of food (energy) that is needed to sustain normal physiological processes such as breathing and digestion. Of this needed energy, 60-75% of those calories account for the total calories expended each day. Measuring ones RMR will allow the professional to determine a valid plan with respect to healthy weight management and/or performance.
Look no further. Indirect calorimetry such as the use of an RMR test is the missing piece to the fat loss puzzle.
