How do you calculate VO2 max from Bruce protocol?

Results

1. VO2max (ml/kg/min) = 14.76 – (1.379 × T) + (0.451 × T²) – (0.012 × T³)
2. Women: VO2max (ml/kg/min) = 2.94 x T + 3.74.
3. Young Women: VO2max (ml/kg/min) = 4.38 × T – 3.9.
4. Men: VO2max (ml/kg/min) = 2.94 x T + 7.65.
5. Young Men: VO2max (ml/kg/min) = 3.62 x T + 3.91.

How long is the Bruce treadmill test?

In the most widely used test, called the Bruce protocol, there are seven stages, each one lasting for three minutes. If you get to the last stage, you’ll be walking at 5.5 mph up a 20% grade. The goal is to get your heart working up to at least 85% of its maximum capacity.

What is 10 grade on a treadmill?

Gradient of the treadmill is the measure of the slope of the treadmill belt. If the belt length is 100 centimeters, 10 percent gradient would mean that the end of the belt towards the hand rail / console would be 10 centimeter (10 percent of the length) higher from the ground than the other end.

Do they numb your throat for a treadmill stress test?

Your throat is sprayed and will be numb. A mild sedative is given and you may sleep through this test.

Is 13 Mets good on a stress test?

Exercise capacity is based on metabolic equivalents (MET) achieved, (one MET is defined as 3.5 mL O2 uptake/kg per min, which is the resting oxygen uptake in a sitting position). Less than 5 METS is poor, 5–8 METS is fair, 9–11 METS is good, and 12 METS or more is excellent.

How do you measure VO2 max on a treadmill?

It is measured as milliliters of oxygen used in one minute per kilogram of body weight (ml/kg/min). The Bruce treadmill test is an indirect test that estimates VO2 max using a formula and an athlete’s ability to exercise on a treadmill as the workload is increased.

What are the stages of the Bruce Bruce Treadmill test?

Bruce Treadmill Test Stages. Stage 1: 1.7 mph at 10 percent grade. Stage 2: 2.5 mph at 12 percent grade. Stage 3: 3.4 mph at 14 percent grade. Stage 4: 4.2 mph at 16 percent grade. Stage 5: 5.0 mph at 18 percent grade. Stage 6: 5.5 mph at 20 percent grade.

Is the Bruce Treadmill test indirect maximal oxygen uptake?

The Bruce treadmill test is an indirect maximal oxygen uptake test. It is considered indirect because it estimates VO2 max using a formula and the person’s performance on a treadmill as the workload is increased.

What is max oxygen uptake (VO2 max)?

Maximal oxygen uptake ( VO2 max) refers to the maximum amount of oxygen that an individual can take in and use during intense or maximal exercise. 3 It is measured as milliliters of oxygen used in one minute per kilogram of body weight (ml/kg/min). The Bruce treadmill test is an indirect maximal oxygen uptake test.
