GERKIN
The Gerkin protocol, also known as the reman’s protocol, is a sub-max Vo2 (volume of oxygen) test.
The test will increase speed and elevation alternately until you reach 85% of your Max heart rate. The
time it takes for you to reach 85% determines the test score (VO2max) as shown in the chart below.
