SCIENCE - HOW IT WORKS
The Science: How it Works
With an accurate measure of both oxygen and carbon dioxide, you get a clear picture of your body’s complete fuel composition. That is, you know exactly when you’re burning the energy-dense fat fuel as opposed to when you’re burning the less-efficient carbohydrate fuel.
A Fit Check metabolic assessment precisely measures – other metabolic systems merely estimate.
A Fit Check metabolic assessment measures several things:
- The amount of calories your body needs to function, including everything from regulating your body’s hormones to thinking the thoughts that run through your mind
- The amount of calories you need to consume each day to achieve your fitness goal, whether that’s weight loss or greater athletic performance
- The point, known as your aerobic base heart rate, is the highest intensity at which your body still uses fat as it's dominant fuel
- The highest sustainable intensity of exercise, known as your threshold, that your body can sustain and still burn fat efficiently
- The rate at which your body absorbs oxygen, which your body requires to burn fat
The Skinny:
Here’s the skinny on what happens when you come in for your assessment:
You receive a personal assessment pack. It includes a comfortable, somewhat stretchy mask, sensors, and accessories that are used during the assessment.
There are two parts to the assessment. You can choose to have one or two assessments, or the combo.
The first part measures your resting metabolic rate (RMR). Fit Check will help you position the mask over your nose and mouth, and then you get to kick back in a chair for about 20 minutes. Hang out, breathe, try to stay awake. That’s all there is to it. (Your assessment will be most accurate if you’ve fasted for a few hours and are well rested. Mornings are a great time for this assessment.)
The second part of the assessment measures your metabolic rate during exercise. This portion requires a bit of get up and go. You’ll put the mask back on, and for 10 to 15 minutes, you’ll walk or jog on a treadmill at increasing levels of intensity. The payoff is worth it: This is where you’ll learn how many calories your body burns while exercising; whether those calories come mainly from fat, carbs, or a combination of both; and at what intensity level you burn calories most efficiently.
And that’s the science-based secret to creating a personalized, fitness plan.
