Data gathered from each protocol demonstrated that the usage of the ramped Bruce protocol achieved more consistent results in comparison across all BMI groups in achieving 80%–85% of their age-predicted maximum heart rate.

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.

1. Use HR and WL data from two or more submaximal stages of treadmill test.
2. Client must reach steady-state HR between 115-150.
3. Determine slope: (b)= (SM2-SM1)/(HR2-HR1)
4. VO2= SM2 + b (Hr max- HR2)

Define the simple VO2 max formula. The simplest formula to calculate VO2 max is VO2 max = 15 x (HRmax/HRrest). This method is considered to compare well with other common formulas. The units for VO2 max are milliliters of oxygen per kilogram of body weight per minute (mL/kg/min).

In the standard Bruce protocol, the starting point (ie, stage 1) is 1.7 mph at a 10% grade (5 METs). Stage 2 is 2.5 mph at a 12% grade (7 METs). Stage 3 is 3.4 mph at a 14% grade (9 METs). This protocol includes 3-minute periods to allow achievement of a steady state before workload is increased.

Maximal oxygen uptake norms for men (ml/kg/min)

Your VO2 Calculations Multiply 0.84 by your BMI and subtract the number from your first result to gain a revised total. Multiply -8.41 by your mile time in minutes and subtract the result from the revised total.

So, one way to determine your max VO2 pace is to warm up, then run for 8 minutes at the maximum intensity level you can sustain for 8 minutes. If, for simplicity’s sake, you ran one mile, then your VO2 max training pace is 8 minutes/mile.

VO2 Max Chart for Men (ml/kg/min)

A VO2 max test is a maximal exercise test performed on a treadmill or bike while connected to a machine capable of analyzing your expired air. Your test provides data on how much oxygen you use as you exercise and determines the maximal oxygen you can consume during exercise.

These are the ranges of VO2max that researchers have identified in the general population. This is where things can get tricky. Similar VO2max results can mean different things for different people. A VO2max of 40 can be excellent for one person, good for another, and only fair for a third.

The average male runner who runs simply for fitness purposes should have a VO2 max level of 50 to 55 mL/kg/min. Women in the same position should score 45 to 50 mL/kg/min. Men who run competitively can expect a VO2 max of 60 to 65 mL/kg/min, while women are likely to have a score of 55 to 60 mL/kg/min.

From the total walk/run time, an estimate of the athlete’s VO 2 max can be calculated as follows: VO 2 max = 14.8 – (1.379 × T) + (0.451 × T²) – (0.012 × T³) “T” is the total time of the test expressed in minutes and fractions of a minute, e.g. 13 minutes 15 seconds=13.25 minutes

Bruce Treadmill Test Stages, Speeds, and Inclines Stage Treadmill Speed Treadmill Incline 1 1.7 mph 10% grade 2 2.5 mph 12% grade 3 3.4 mph 14% grade 4 4.2 mph 16% grade

VO2_max = METs_max * 3.5 For elderly or frail patients, a modified Bruce protocol METs exists. The modified Bruce protocol stress test adds a stage 0 and 1/2 at the beginning. They are performed at 1.7 mph (2.7 km/h) and 0% and 5% treadmill inclination.

For an estimate of your VO 2 max, enter the run’s duration and then select the ‘Calculate’ button. For an analysis of your VO 2 max score see the VO 2 max page. Analysis of the test result is by comparing it with the athlete’s previous results for this test.
