I will be racing SSCX this season and won’t have the luxury of spinning a low gear and have been incorporating some lower cadence (65-75 RPM) work into my Sweet Spot workouts.
I’ve noticed that low-cadence work elicits a higher heart rate (usually a 5-10 BPM increase) than higher cadence at the same wattage. This is especially evident if I’m out of the saddle doing high-force standing pedaling. I’m wondering why this could be (less efficient Type 2 fibers?), and if I should continue to work on low-cadence in order to better adapt this system and whether or not there fitness benefits or gains to be made by doing so.
