Physiological models for estimating internal mechanical power (IP) generally share a common basis: the sum of IP and external (EP) is equal to total power, as represented by net VO2.  While biomechanical perspective argues against this simple summation, physiological serve valuable purpose because they account flow energy through system.  Despite their foundation, estimates using various have not been consistent.  Two pre-existing that use approach, well variations them body mass-cadence relationship, were applied submaximal data from eight well-trained male cyclists.  Three incremental cycling tests performed at cadences 50-55, 80-85 110-115 rev • min-1.  Differences in mean limits agreement used show values calculated two previously described similar any tested.  It was also shown relevant equivalents converting VO2 into metabolic produced smaller than when generic equivalent. published literature, therefore, might necessarily be caused differences participant characteristics, but rather accuracy variables are input models.
