In two articles Timothy Noakes proposes a new physiological model in which
skeletal muscle recruitment is regulated by a central "govenor," specifical
ly to prevent the development of a progressive myocardial ischemia that wou
ld precede the development of skeletal muscle anaerobiosis during maximal e
xercise. In this rebuttal to the Noakes' papers, we argue that Noakes has i
gnored data supporting the existing hypothesis that under normal conditions
cardiac output is limiting maximal aerobic power during dynamic exercise e
ngaging large muscle groups.
