TRAINING WITH POWER
The power formula applied to indoor cycling is as follows:
•
Power is the amount of work being done, measured in Watts, by the cyclist in a given amount of time
• Force is the amount of resistance from gear 1 to 24
• Velocity is speed, indicated by the cadence (RPM) at which the rider is pedaling
• Power, speed and force are related. Power measures work intensity and it is modified by the two
variables of force and speed (distance/time).
To maximize power output, riders must regulate gear and RPM. While pedaling fast may appear
challenging, without any resistance the power output is low. In contrast, pedaling very slowly with
high
gears may also provide a less than desirable Watts output. Therefore, to maximize power output,
manipulation of gear and RPM must be considered. In terms of effort, both components of power must
be factored in.
