(Sorry, I have to ask) but results in what?
It sounds like there's a risk of focussing on (endurance) athletes, not on unfit sedentary desk workers. Talking about which of the former benefits most from which particular training methodology could be missing the point, which is that it's the latter who are the group who really need to get off our backsides to improve our general health.
In other words, getting a few extra % of performance out of already fit people is of interest to a minority, but is irrelevant as far as public health policy is concerned.
