Active Metabolic Exercise Test (VO2 Max)

You’ll be using exercise equipment for this test, typically a treadmill or a stationary bicycle, although other cardio exercise equipment may be selected. A ramp test is the best method for identifying your limitations, zones and VO2peak. It consists of a 3 minute warm up, a 9-12 minute incremental test where the intensities will increase every 1 minute until reaching your maximum effort followed by a 2 minute inactive recovery (no movement). If you are completing a treadmill test and plan on using your results for training on the road, the treadmill should be placed at a 2% incline to mimic the road resistance that you do not have on a treadmill. If you are completing a bike test, your cadence should be maintained between 80-100 RPM throughout the test.


The PNOĒ 12 minute exercise fitness test will reveal how effective you are at using oxygen, burning fat and carbohydrates. This test will reveal which of your cardiovascular, respiratory, or muscular systems is the limiting factor in your performance. Your test will also provide the most accurate training zones available in your heart rate, so you can maximize the effectiveness of your training, develop individualized nutrition and workout plans to improve your performance.

What Does PNOĒ  Breath Analysis Measure?              


  • HR = Heart Rate or the number of times your heart beats in a minute (BPM)

  • VO2 = Volume of oxygen consumed per minute. (ml/min)

  • VCO2 = Volume of carbon dioxide consumed per minute. (ml/min)

  • BF = Breathing frequency in breaths per minute.

  • VT = Tidal Volume, The amount of air you breathe in per breath.

                                                                                                                                  Extrapolations based on VO2 and VCO2


  • Total CAL = Total calories burned per minute. (KCAL/min)

  • CHO = Carbohydrates burned per minute. (KCAL/min)

  • FAT= Fats burned per minute. (KCAL/min)

  • RER = Respiratory Exchange Rate, ratio of VO2 to VCO2.

  • VE = Minute Ventilation or Minute Volume, 

           volume of air breathed per minute = BF x VT (l/min)

  • VE/VCO2 = Volume of air breathed per minute per volume of CO2 expired per breath.

  • VE/VO2 = Volume of air breathed per minute volume per 

Active Metabolic Exercise Test Preparation (V02 Max)

As part of the preparation for your PNOE exercise  test, we ask that you please adhere stringently to the following recommendations.

 No intense exercise or any exercise of more than one hour 24 hours prior to the test. Continue medications as usual. Wear appropriate workout clothing and shoes. You will need a bottle of water and a towel, and perhaps a snack for after the test. Before your exercise test, you will create a customer profile on our mobile app. You will be fitted for a mask, backpack and a polar chest strap. 

 We'll then move to the exercise equipment you selected and establish the exercise intensity levels for your unique physical conditioning.

Once your intensity levels for the test are identified and a protocol is created, you will begin your exercise test.

 The test is divided into three parts, a three minute warmup, a nine to 12 minute incremental test where the intensities are increased every one minute throughout the test and a three minute inactive recovery. 

 Your results will be emailed to you within 48 hours. We will contact you to schedule a time to review the results of your exercise test.
