The Central Governor Model (CGM) is probably one of the most important and controversial theories in Exercise Science. I should recognize that this theory helped me to better understand Exercise Physiology and the complexity of the fatigue phenomenon during my early academic years. However, this theory would present some important flaws as the most criticized cardiovascular/anaerobic model. Some of these limitations are epistemological. My arguments are presented in form of a letter (attached) I previously sent to BJSM with regard to an interesting brief essay. Unfortunately, this letter was not considered for publication. Any comments and suggestions are welcome.
The CGM is a particularly flawed model because it fails to predict and cannot explain known phenomenon. It cannot explain many things including why isolated muscle preparations exhibit fatigue. But, mostly, the central tenant of the theory, that a central governor exists to prevent injury, fails because serious injury due to a whole host of reasons continue to happen. Plus, the theory doesn't include a mechanism but requires some sort of magical feedback and control mechanism. This "theory" only remains in discussion because of the dogged persistence of a few advocates who point to a couple of studies that show the CNS can modulate exercise intensity and that people can be tricked to go beyond what they think they can do.
When models fail to account for all of the data they need to be modified. The CGM is in need of great modification if it wants to be taken seriously.
The opinion piece by Hopkins is worth having a look at, IMO. Available here:
