Indoor rowing energy cost depends on the mechanical work required to move the flywheel. Speed dictates power output, which directly influences oxygen consumption and metabolic rate. The calculator converts distance and time into average speed, derives a 500-meter split, and matches that split to a metabolic equivalent of task (MET) before computing calories using , where is body mass in kilograms and is workout duration in hours.
Concept2 performance monitors typically report pace as time per 500 meters. Because MET values rise as splits fall, monitoring improvements in split times offers a direct indicator of energy output and cardiovascular stress.
Compare your pacing against common training zones.
| 500 m split | Approx speed | Estimated MET |
|---|---|---|
| 2:30 | 12.0 km/h | 6.0 |
| 2:05 | 14.4 km/h | 8.5 |
| 1:50 | 16.4 km/h | 10.0 |
| 1:35 | 18.9 km/h | 12.0 |
Matching your workout to these benchmarks helps tailor training plansโsteady-state rows stay near 6โ8 METs, while high-intensity intervals push beyond 10 METs.
Alternating rowing with other endurance or strength work balances repetitive strain and keeps training fresh. Hydration, technique drills, and active recovery sessions support consistent progress.
