Higher cadence in cycling at the same power output can lead to increased gross power and oxygen consumption.

“what happens that that you you start to go at the higher Cadence if you now actually measure your gross power and your net power you start to see that yes the net power is the same but the gross power actually starts to go up when you're starting to bring up your Cadence as well which tells why the V2 now also starts to go up because the the V2 or the oxygen consumption doesn't care about your propulsive power it requ it cares about how much power is required it's counting both the usable and wasted energy exactly”
