Springfield, MO: On this Fit Friday, we're at the Body Composition Lab on the Missouri State University campus.

Paul says and show us, "we'll be ramping up the incline and speed on this treadmill in what's called a VO2 Max test."

Noah Alldredge says, "it's similar to a stress test... It's really appealing to fitness enthusiasts like yourself Paul.... It's a good way to test your overall fitness level when it comes to cardiovascular endurance."

Paul adds, "we could go into the formula-- but, let's keep it simple. It measures how well your body delivers oxygen to your muscles.. So, you get a snapshot of your current fitness level.

Noah Alldredge adds, "this is measuring Oxygen and CO2. "

Paul explains, "our own Sara Forhetz agreed to wear that funny looking mask and take the woman versus machine challenge."

Noah tells Sara, "you're gonna start off... At 2 miles per hour and zero percent incline and every minute we're going to increase the speed or the incline of the test."

Sara responds, "okay."

Noah tells us most people make it for about 10-to-12 minutes...

In the video you can see Noah tell Sara, "you'll really start feeling it at about 5-to-6 miles per hour."

Noah adds, "when you're done with the test... just step off to the side..."

Paul explains, "Sara did better than average....."

Noah delivers the results, "your VO2 peak was 58... Which puts you at superior fitness level.. "

Noah says, "you really can't do much better than superior..."

Paul asks, "and if somebody wants to come in and test this out?"

Noah says, "they just call up here to Missouri State. The Body Composition Lab at the Professional Building and it's 75 dollars for the VO2 Max test."

Paul concludes, "that's VO2 Max testing on this fit friday."

On the web, MSU explains the test this way: The VO2 max treadmill test is an incremental test to voluntary exhaustion. By measuring the amount of oxygen you breathe in and out you can calculate the maximal amount of oxygen that your body can use during exercise. This is an indication of your aerobic fitness as the more oxygen your muscles can take up and use to produce energy, the higher power output you can attain. When the test begins it will seem very easy. The intensity will increase by small increments every 1-2 minutes and will continue until you cannot keep pace and fatigue, which forces you to stop. You will wear a heart rate monitor throughout the test and also be fitted with a face mask to measure the air you breathe in and out for VO2 calculation.
