Some of them can put out impressive amounts of power, at least in short term efforts.
Steroids?
The CA data is from CA members, possibly some track racers considering the amount of power claimed.
The running data is aggregated from 20 years of available 5K race results. The chart looks very similar to the CA chart if you reverse the x-y axis.
The VO2 data, is unclear where they got it, or else calculated from some other data. I probably shouldn't list it without more investigation but it's strikingly similar to the other charts.
