Vo2 Max Test: What To Expect
Prepare! To prepare for your test, we recommend prioritizing rest. Taking it easy the day before, whether through gentle activities or complete rest, will ensure you perform at your best.
Test Day! The test is performed on our treadmill or a bike (bring yours). The test starts at an easy, warm-up pace and gradually increases in speed and intensity until you reach peak exertion. Our system tracks your oxygen consumption, heart rate, and energy output in real-time.
You Made It! We’ll conduct a brief data review after the test, and later send you a detailed report to help you fully understand your results. This includes a summary of important performance data and your optimal training zones. If you’re interested in The FAST Lab designing a training plan tailored to your results, let’s discuss!
