Fatigue: Mental vs. Physiological

I've came across this interesting article from "The Science of Sport" (you may find it here). Is fatigue a result of our conscious "Anticipatory regulation" or a result of muscle impairment?

It analyses some interesting questions like:
- If it was all physiological why do the best 10k races have the fastest last lap when the athletes have the biggest glycogen depletion and the biggest amount of lactate in the muscles? Why don't they speed up before?

- What cues, what signals, what experiences, what training, and what physiology are responsible for enabling the athlete to consciously slow down in the middle, and then speeding up at the end of a race and still optimize performance?

These guys, exercise physiologists have found their scheme between mental and physiological that just seems perfect to me and it ended being published at the British Journal of Sport Medicine.

If you're curious about it, you have a whole series of texts about this theme that will fill a great amount of hours of your spare time(you may find them here)

I've just a few time to write this post. Tomorrow I'll participate in a great training camp in Alentejo and I still have some hours of sleep to recover from.

I hope you find the article really interesting. And you can read more articles, proving performance is regulated, and not limited only by single organs or H+, Pi or low Ca++. Search for T.D. Noakes, J. Swart or R. Tucker, and you will find evidence for a cenntral regulatory model, based on anticipation, reserve, feedback,pacing and end-spurt phenomen.
