What is it to be "high performance"? Does it simply mean to be the best in the field of sports? If so, that is curious, as we do not speak of "high performance musicians" or "high performance actors" or "high performance doctors".
No, the language of late modern sport is the language of the machine, and one would talk of high performance in this context as if describing a particularly well-oiled engine, tweaked and tuned to achieve maximum velocity. Citius, altius, fortius is how one might understand it in translation.
In this sense we may consider the "high performance athlete" the siamese inverse of the "muscle car", with the machinic reading of the former intimately connected to the anthropometric reading of the latter.
With that in mind, one can only note the irony after Michael Waltrip's crew chief was fined and suspended at the Daytona 500 NASCAR race for illegally injecting a substance contained in jet fuel into Waltrip's car.
Citius, altius, fortius, copiosus?
