My cadence has definitely suffered badly recently. I used to be at the upper end of average cadence. Even when I started road cycling I was doing rides 100 to 105 cadence, but I think looking back that was partly due to me doing the spin bike for a year before getting a road bike.
I’ve kept a high cadence for years until recently when I’ve upped my volume and rode outdoors almost exclusively (15 to 20 hour weeks). I’m climbing a lot and a lot of it at low cadence to keep myself in Z1 POL, but recently I feel it’s stressful to get into those higher cadences.
Last week when I was doing my POL intervals I was slogging them out at 75 to 85rpm. That’s really low for threshold and VO2 work, especially for me. Although quite impressed with my ability to now do that, seems my legs are stronger at this range and don’t tire as quickly, I knew I’d still burn out and it wasn’t sustainable when really doing longer efforts.
I’m wondering if this is related to the fatigue I was feeling today jumping back on the trainer and on ERG mode. The intervals weren’t as hard as what I was doing outdoor lately (4x8 etc) but I still dropped the power. Think it was called spaded sweetie that group workout.
As a side note - how long does it take to change muscle fibres from one type to another?
