Aerobic Fitness Testing

Aerobic Fitness Testing (VO2max, submax, and Lactate Threshold testing)


Cardiovascular fitness can be measured by performing a maximal or submaximal exercise test on a bicycle or treadmill. Knowing your aerobic fitness level and lactate threshold can be useful for setting fitness/training goals, determining proper individual exercise intensity, and evaluating the results of an exercise program.  

All testing is done by appointment. Please call 801-585-7325 to schedule your test.

Submaximal Aerobic Fitness Testing ($70 Community, $60 University)


The submaximal aerobic fitness test is a graded exercise test performed on a bicycle. This test will give you an accurate estimate of your aerobic fitness level, allowing you to compare your cardiovascular fitness to others in your age group.  Knowing your aerobic fitness level can be useful for setting fitness goals, determining proper individual exercise intensity, and evaluating the results of an exercise program.

Submaximal aerobic fitness test protocol

  • All testing is done by appointment. Please call 801-585-7325 to schedule your test.
  • 45-minute appointment
  • A submaximal aerobic test involves exercising 75-85% predicted max heart rate
  • Generally completed on bicycle ergometer
  • Heart rate and workload are used to predict maximum oxygen uptake
  • Great test to determine cardiovascular fitness
  • Test takes approximately 12-15 minutes
  • Results are available immidiately after the test is completed
  • PEAK exercise physiologist will explain test results

VO2max Maximal Aerobic Fitness Testing ($105 Community, $90 University)

VO2max (maximal oxygen uptake) is accepted as the criterion measure of cardiorespiratory fitness. PEAK uses open-circuit spirometry to accuately measure VO2max. Athletes can use VO2max testing information to determine training intensity and gauge results of a training program. Following American College of Sports Medicine (ACSM) guidelines, we cannot test men older than 45, women older than 55, or individuals with 2 or more risk factors As we do not have a physician on staff. Please check our risk factor list prior to making an appointment.

VO2max Protocol Information

  • All testing is done by appointment. Please call 801-585-7325 to schedule your test.
  • 75-minute appointment
  • Graded exercise test lasting 8-14 minutes (not including warm-up and cool-down)
  • Can be completed on a treadmill or a bicycle
  • Heart rate is monitored
  • Athlete will wear a noseclip and mouthpeice to capture exhaled air
  • Oxygen uptake is measured with a metabolic cart
  • Results are available immidiately after the test is completed
  • PEAK exercise physiologist will explain test results

Lactate Threshold Testing ($105 Community, $90 University)

Lactate threshold (or anaerobic threshold) is a good predictor of athletic endurance performance. The lactate threshold is a point during physical activity at which blood lactate builds up faster than the body can remove it.  With proper training athletes can increase their lactate threshold and are thus able to tolerate higher intensity exercise for longer periods of time. Knowing your lactate threshold can help to determine a training regimen to improve athletic performance.

Lactate Threshold Protocol Information

  • All testing is done by appointment. Please call 801-585-7325 to schedule your test.
  • 75-minute appointment
  • Graded exercise test
  • Can be completed on a treadmill or a bicycle
  • Exercise intensity is increased in periods of about 3-5 minutes
  • Blood samples are taken with a finger stick at the end of each period
  • Heart rate will be measured
  • Process continues until the blood lactate concentration increases significantly
  • Results are available immidiately after the test is completed
  • PEAK exercise physiologist will explain test results
