Power Data Estimates for the climbing stages

Page 159 - Get up to date with the latest news, scores & standings from the Cycling News Community.
It can be seen that VO2max decrease is never bigger than air pressure decrease (for your info: air pressure at 1000 m is about 900 hPa (10% decrease vs sea level), at 3000 m about 700 hPa (30% decrease), at 5500 m about 500 hPa (50% decrease). It's basically proportional for lowest dots - almost linear dependency between air pressure and VO2max meaning that oxygen amount being the bottleneck in human engine.

BTW: Holly, molly! Who had a 15% VO2max decrease at circa 5200 m ASL? Superman Lopez, Superman from Krypton or some extremaly unfit fatty?
Clearly, among the 146 data points in this meta analysis, many are non sensical. Maybe the author could have spent some time weeding out the worse results.

I suppose a hypothetical person who has such a small VO2max decrease has a super-high blood cells content (a high mountain resident) and on top of that poor physical fitness (isn't able to utilize high oxygen amount circulating in his blood at a lower elevation).

Oscar Soliz or some other crazy Bolivian cyclist. ;)
 
Interesting article on Pogacar.


What is funny is that this is far beyond what was deemed possible just a few years ago. Anything above 6.5, I believe, was deemed impossible. Now you are just called greatest cyclist ever and admired, instead of question marks. Geraint is ridiculed for not attacking him for instance... Odd times.

The article is incorrect since they are using Arensman data to make predictions, but the problem is the strava of Arensman was incorrec because he had problems with the weight. He had more 4/5 kg than his normal weight.

He probably did something close to 6.2 w/kg on Grappa. Arensman said he gained weight during the Giro, almost 5 kg heavier. I'm not saying Pogi is not doping, of course he is but 6.5 w/kg is an all time performance, being in the same league as Riis in Hautacum.
