The main difference here is the frequency, duration and how much the power swings are. 30 seconds no problem it’s the ones that are doing it every few seconds that look suspicious.
A lot of people will push on and off the power when climbing but not to the point of almost sprinting then literally stop pedalling.
I don’t see any reason to stop pedalling in Zwift other than when supertucking. Possibly positional if you have gone too hard and find yourself on the front but if you judge things right there is no reason.
For anyone adjusting your socks for a second, and then you have to burst to 10w/kg to catch up, then adjusting your kit, and then you have to burst to 10w/kg to catch up, and so on every other second or two, continuously, maybe just don’t adjust your socks, kit, etc ?
Thanks Jamie for replying.
Just for clarity, I don’t think I’m defending the practice and hope my comments are not perceived as such.
The original video is clearly showing micro bursts to get an advantage.
It has power and cadence available for review.
In the graph submitted by C A Cestria, we review HR and power.
Is that enough?
The guy in question has wide fluctuations of power but there’s no scale, his HR is flat.
By contrast, C A Cestria has a much flatter power curve but increases his HR.
I asked if that graph was enough to determine microbursts and if so, how would one define it in a way to code.
There needs to be a better definition than I know it when I see it.
I agree that cadence seems important.
Zwift should include cadence graph so more situations are reviewed by the community and a proper working def can be developed.
You make an excellent point of people not understanding how microbursts different from normal riding and workouts.
I want to review my own rides and would like to post the data for review to demonstrate to others the difference.
I don’t know how to do so.
All my rides go to Strava and Zwift power and my accounts are public.
On 1/19/23, I did a 40/20 work out and the first block was performed out of saddle and the second was seated.
Never was my cadence 0.
My TDZ ride on 1/17/23 was basically rode as a race and I started out of saddle and held watts high until the lead settled.
I think both cases show non microbursts.
I think I’ve misinterpreted microburst as ALL increases in power without a corresponding increase in cadence.
I do think increases in power should probably also show an increase in HR.
Is that correct?
I don’t think cadence necessarily has anything to do with Microbursting. Eg. simultaneous shift of small to big ring in front while also shifting multiples on the rear, could yield small cadence differences but large power differences.
As for HR, I thought the frequency of up/down on power was faster than a human’s HR is going to change – talking about a few seconds or so up, and then a few seconds down.
I’ve looked up the graphs from the original as there is no scale to check, the swings are from 550w to as low 30w. All the peaks and trough are a 500w swing in quick bursts ie microbursts, I’d say if your HR is around threshold this kind of riding will just keep it there and not ramp up like C A’s did by doing a solid effort.
Cadence charts helps to see it but really a very spikey power chart (with scale to see how high the swings are) is enough to see microbursts in action.
This is the same guy as original post, proving on a climb he can ride at steady wattage, or when needed deploy microbursts. His heartrate climbs a lot more doing a steady efforts and actually recovers using microbursts.
I think he’s actually trying (and succeeding) to sticky watt. If you look at the raw numbers of the data on the Strava post for that ride (I think I have the same one), there are a ton of 2x and 3x repeated power numbers in the spiky parts.
That’s interesting to see. It was always my contention that this was most likely to be just a slightly different manifestation of sticky watts and not some magic zwift physics whereby the equations of motion were briefly suspended if you pedalled in a particular style.
