Do we really need a central governor to explain brain regulation of exercise performance? A response to the letter of Dr. Marcora

摘要

We would like to thank Dr. Marcora for his carefully argued response to our recently published paper (Crewe etal. 2008). In his response, Dr. Marcora indicates his acceptance that the brain, rather than some other organ, regulates human exercise performance. The debate between us represents a departure from the historical emphasis on "peripheral fatigue" as the mechanism "limiting" exercise performance. What remains are minor differences in our understanding of how the brain regulates exercise performance and in particular the role of the ratings of perceived exertion (RPE).
