On the menu is standard 5x5min Vo2max bike intervals in Erg mode. My normal cadence is around 85.
This is what happens: I start out happy and excited with cadence 90+, HR reaches Vo2max range after about 1-1.5m, start feeling the burn in legs. Last minute(s) the cadence drops to sub 70 but HR and power is high and constant (92%+)
What exactly is happening here from a training adaptation, I train the vo2max (as confirmed through high HR and power) but what is the physical impact of the lower cadence at this point of the interval? Do I improve the lactate transportation / utilization (Vlamax) while maintaining the Vo2max benefit (leg burn is massive)
To me it would make limited sense to lower the power just to maintain the cadence if that would lead to lower HR (since the purpose of the session is Vo2max development).
Appreciate input!
