99% of people who can't do 40 push-ups are going to fail because they don't have the strength. Firefighters are probably one of the only demographics where you are going to get a non-trivial percentage who have the strength but not the cardiovascular health required.

- Alex3917 8y agoI mean it's not surprising that, in firefighters, pushups would be a better predictor of cardiovascular health than a VO2 max estimation. For the treadmill test, they cut participants off at 85% of their predicted max heart rate. Whereas with 40 push-ups you're pretty much guaranteed to be at your actual max heart rate after the first 10 or 15. In other words, push-ups are probably a better measure of cardiovascular fitness than the treadmill test, but only for the tiny percentage of the population who isn't limited by strength.
