Concept2 Pace Derivatives Chart

Concept2 ergometers display pace, watts, and calories per hour on the performance monitor during a workout. The charts below display each of these, as well as speed, to help in planning and performing your workouts. Mouse over or tap to see metrics at a given pace.

Below are descriptions of the terms and math involved in calculating the various metrics in the charts above. Reading these is not necessary.

Split

Pace is the time in seconds to cover a set distance — 500m for RowErg and SkiErg, 1000m for BikeErg. It is the basis for every other metric above.

Power

The monitor shows power (P) each stroke, measured in watts.

Calories per hour

Roughly how many calories a 79.5kg individual would “burn” over an hour, based on power (P) and time (t). First, mechanical work (W) in kilojoules:

Then calories per hour (E):

(See The Physics of Ergometers, section 11 for information on the constants.)

Speed

Speed is not shown by the monitor. It is calculated by scaling the pace across an entire hour, and is measured in kilometres per hour.

Note: speed is calculated and shown here to provide rough equivalency between Concept2 ergometers and other machines in terms of distance and time. This does not equate to effort or energy expenditure.
