VO2 Max

Determine Your Heart Rate Zones

Schedule an Appointment

Our VO2 Max assessment takes the guesswork out of training by analyzing an athlete's oxygen consumption while they run on our treadmill.  The collected data defines their heart rate training zones so they can maximize their training efficiency and minimize their risk of overtraining.

Systems Tested:

  • Aerobic or Ventilatory Threshold (VT): VT is determined from ventilatory changes that reflect a trend change in your CO2 extraction, O2 consumption, and breathing volume and rate. This is the top end of your aerobic zone and your maximum ability to promote endurance.
  • Anaerobic Threshold (AT): More fatiguing than your VT, AT is a non-sustainable level of exercise intensity. At AT, your body can no longer utilize fat and oxygen to meet energy demands.
  • Peak Oxygen Consumption: Peak Oxygen Consumption is the maximum amount of oxygen that can be transported and used by your working muscles.

Cost of Test: $100. Cost includes VO2 Max assessment, printed results, goal consultation, and a customized 8-week training plan based on your results.

Test Duration: 90 minutes 

Test Location: Fleet Feet Training Center - 11731 Manchester Road, Des Peres, MO 63131 

Test Protocol: The VO2 Max assessment is done via a graded exercise treadmill test that increases in speed and/or incline.
