Dr Coggan,
If someone put you on a computrainer at 95% of your FTP, when well trained, what would your lactate, measured by a finger prick look like every at 10, 20..60min ?
Would it be steady ? Over 4mmol/L after 20-30min ? Rise by x every y minutes ? I am just curious what the profile would look like, roughly
Assuming that my FTP was established on said CT, then I'd predict my lactate levels to be constant over time, perhaps peaking after 5-10 min then gradually decreasing. It is harder to predict the exact concentration, but considering it was difficult to drive my blood lactate levels above 8 mmol/L, I'd expect them to be rather low.
(I actually did almost this exact protocol back when I was a grad student, but haven't looked at those data in years and years.)
Thanks.
That is the exact pattern I see. In fact I measured at 8,16,24,32 and 40. At 8min it was 3.7, highest value was at 16min (4.8) then dipping to 4.5 and remaining there.
The fact it's stable, that's the SS, correct ?
Does the fact it's over 4 provide any insight ?
It may not be MLSS because maybe at 10watts more I would be at a stable 5.6 ?
I may have to try it at FTP rather than 95%.
I do this because I find it interesting to see what's going on under the hood. No other reason.
