Cycle
Test
Equipment: Cycle
ergometer, stopwatch, pulse monitor.
Target Population: Anyone.
Advantages: Simple to
do, reasonably accurate, easy for ECG monitoring.
Disadvantages: High
max heart rate makes test under predict and test is less accurate
with advancing age.
Validity: Approx 0.85
correlation with gas analysis methods.
Procedure: Set up the
cycle ergometer with correct handlebar and seat adjustments (leg
should be almost straight at pedal bottom).
Choose a load to begin the test
(Loading Wattages Table).

| Whether
you use the lower or upper wattages will depend
upon your weight and fitness level. They are intended
to raise pulse to steady state 130-160 bpm. |

Pedal at 60 rpm for 6 minutes
at chosen loading, taking pulse every minute. Your pulse rate should
be steady state (130-160 bpm). If pulse is not in target range (above
or below) after 2 mins adjust loading by 25 watts accordingly for
remainder of the test.
At the end of minute 6 record
your pulse and resistance loading.
Calculate your Max VO2
from the Astrand nomogram by joining up the two points with a ruler
(use the age adjuster if you are not 20-25 yrs).

Convert your l/min Max VO2
to ml/kg/min by multiplying it by 1000 and dividing by body weight
(kg). Then check your Max VO2 rating below.
