VO2 test
The VO2 test is based on the Gerkin protocol, also known as the
reman's protocol, and is a sub-max VO2 (volume of oxygen) test. The
test will increase speed and elevation alternately until 85% of Max
heart rate is attained. The time it takes the heart rate to reach 85%
determines the test score (VO2max) as shown in the chart below.
