Rowing Power Output
What is Rowing Power Output?
Power output in rowing is calculated from the flywheel deceleration curve on a Concept2 ergometer. The PM5 measures flywheel velocity during and after each stroke, then computes the work done per stroke. The standard formula relating power to pace is: Watts = 2.80 / (pace in seconds per metre)³. For example, a 2:00/500m split equals approximately 203 watts, while a 1:40/500m split produces about 350 watts. Power is the most objective measure of rowing effort because, unlike split time (which is derived from power), it scales linearly and is unaffected by drag factor settings. Tracking power output over time is the best way to measure fitness improvements, set training targets, and compare performance across sessions.
How Watta Uses Rowing Power Output
Watta's Work Output component (35% of the Effort Score) is directly built on power output data. Higher watt output relative to your personal baseline earns more Work Output points, making power tracking central to the entire Watta scoring system.
