MEASURE
YOUR POWER
POWER - Superior to monitoring hear t rate
which is only a measure of how hard the
human body is working internally, power
output for a cyclist is the amount of work
generated into for ward motion. Power
equals work multiplied by time. Work for
a cyclist is the force applied to the crank
arm times the cadence. Multiply this by time
and we get power. What this means is that
power is a definitive value of a cyclist ’s
performance. Unlike hear t rate, there are
no variables with power.
Training to specific power outputs usually
requires the use of a crank system such as
those made by InfoCrank, Power2Max, or a
rear wheel based device like a PowerTap hub.
Using the Revbox as a training tool, a rider who
does not have a crank based system can use
the supplied laminated handlebar char ts. These
align fan speed with power, with the fan speed
being picked up by a wireless cycle computer.
While not as accurate as a crank based system,
this method is an adequate way for a rider
without that equipment, to gauge their power
while training on the Revbox.
From in depth personal fitness tests, with
protocol explained in the supplied Revbox
manual, a rider is able to create an athletic
profile of their current physiological capacity.
This information can be used by the rider to
train to cer tain power outputs, maximising time
and efficiency. Just with an additional cadence
computer, even a rider without power measuring
cranks is able to train ver y specifically for their
goals using the Revbox.
