CYCLE ERGOMETER
MAXIMAL EXERCISE TESTS
4.4 The cycle ergometer is a widely used instrument for
assessing cardiorespiratory fitness and is the preferred
modality for exercise tests conducted on individuals
or jog on a treadmill (Balady et al. 2010). On a fric-
with conditions affecting their ability to safely walk
tion-type cycle ergometer (see figure 4.5), resistance is
applied against the flywheel using a belt and weighted
pendulums. The hand wheel adjusts the workload by
tightening or loosening the brake belt. The workload
on the cycle ergometer is raised through increases
in the resistance on the flywheel. The power output
is usually expressed in kilogram-meters per minute
(kgm-min-¹) or watts (1 W ~ 6 kgm-min-¹) and is easily
measured using the equation
power = force x distance / time
where force equals the resistance or tension set-
ting on the ergometer (kilograms) and distance is
the distance traveled by the flywheel rim for each
revolution of the pedal multiplied by the number of
revolutions per minute. On the Monark and Body-ow
guard cycle ergometers, the flywheel travels 6 m
per pedal revolution. Therefore, if a resistance of 2
kg is applied and the pedaling rate is 60 rpm, then
power = 2 kg x 6 m x 60 rpm = 720 kgm-min-¹
or 120 W.
To calculate the distance traveled by the flywheel
