The only difference was a lower heart rate with the lower cadence.
Example: Tray Mountain
High Cadence - Avg Cadence 95 RPM - Power - 128w - NP - 135w KJ - 691
Low Cadence - Ave Cadence 72 RPM - Power- 128w - NP - 135w KJ - 691
I want to build a little more power for hills is the reason I am going higher force, lower cadence. But, I want to know if the calorie burn is the same since I am getting less of an aerobic workout.
the calorie burn assumes a metabolic efficiency of ~25% which can vary from individual to individual and within the same individual depending on various parameters like cadence/hr/temp etc. How much you won't know unless you get tested in a lab. The difference won't be huge. Concern yourself with the training adaption, not the minimal differences in calorie burn
