I don't attribute all of that to equipment because even runners are getting faster, though there is some discussion that we are approaching the limit at which a human can run 100m.
If everyone is getting faster, that doesn't change the calculus for racing. You still have to go faster than everyone else at the end.
I think it's just another excuse for losing.
