Your Results
VO₂max from Cooper (1968): (distance in meters − 504.9) ÷ 44.73. METs = VO₂max ÷ 3.5. Percentile estimated against FRIEND treadmill CPET reference standards (Kaminsky et al., Mayo Clin Proc 2015/2022) for your age and sex, interpolated from published 25th/50th/75th percentile values. Treadmill norms; a field estimate from a run test will differ from a lab-measured value.
Metabolic testing.
Sutherly offers four different metabolic tests to suit the need of the patient or athlete.
VO2max / CPET
Lactate
Lactate + VO2max
Comprehensive Thresholds
Below you will find specific information on each test.
-
Beginner to Advanced
This test involves 8-20min of effort, ramping up step by step until exhausion. While VO2max is a priority metric, this test also employs clinical Cardiopulmonary Exercise Testing (CPET) techniques to evaluate lung function and lung strategy. This test includes heart rate zones.
Test is $175 with an option to add $25 for resting lung function analysis to then compare to exercise lung function. -
Intermediate to advanced
This is a traditional lactate test that aims to find heart rate and pace/power of LT1 and LT2. This test involves 45-60min of running and periodic blood sampling taken from one’s ear.
This test costs $205.
-
Advanced
This test incorporates lactate testing and VO2max (but not CPET). This is a grueling test that involves an abbreviated lactate test followed by a VO2max effort. This convenient test provides acceptable accuracy of these measures but lacks the precision of when done on their own.
This test costs $295.
-
Pro
This test pulls out all the stops. It gathers every metric, from VT1 and LT1 to critical speed/power. It involves both resting lung function and active lung function, and employs CPET insight to these metrics. It is the ultimate “what is my bottleneck?” test. This test involves 45-60min of effort while gathering VO2 information and blood samples. This test does NOT evaluate VO2max.
