- Power/Weight: Higher is better - indicates efficiency.
- Adjustment Formula: Uses Concept2's weight factor calculation.
- Heavier Athletes: Generate more absolute power but less per kg.
- Lightweights: Often have excellent power-to-weight ratios.
The Concept2 Weight Adjustment
Concept2's weight adjustment formula corrects for the advantage heavier athletes have in absolute power production. The adjusted time is calculated as: Adjusted Time = Raw Time × (body weight / 270 lbs)^0.222. This 0.222 exponent is empirically derived and accounts for the non-linear relationship between body mass and rowing power. The result lets a 60 kg lightweight be compared directly against a 95 kg heavyweight.
