.. Running Economy. Once again, it does not measure what we think it does. This has been dabled in for years in cycling (Which is an interesting story…They found that cyclists preferred pedaling at high revolutions per minute, while the research
showed that pedalling at a low RPM was more ‘efficient’ when measured via economy (VO2)…They were baffled. Then some guys got the bright idea of measuring efficiency in a different way (energetic cost- basically in joules/per kg/per meter, or thought of as how much energy does it take to cover a distance) and they found that in terms of this efficiency, cyclist were more efficient at high RPMs…just like the elites preferred…Similar research is starting to happen in running).
