"You can teach a person how to run, but you can not teach a person courage"

"Looking for fatigue in all the wrong places Noakes starts with a review of the history of the study of fatigue, which mostly focused on efforts to find the ultimate limitations of human exercise capacity in the body, such as the muscles or the heart. The problem with this approach is that it does not explain why athletes almost invariably simply choose to stop exercising before such bodily limits are reached (some of which would result in catastrophic injury or death.) For Noakes “the presence of the noxious symptoms of fatigue must indicate that exercise cannot be regulated solely by an inevitable and unavoidable failure of skeletal and or cardiac muscle functions.” Here are some common observations that are not explained by the theory that exercise is limited by some single factor in the body: athletes begin exercise at an intensity which is appropriate for the expected duration; athletes run harder in competition than in training; athletes speed up at the end of exercise (the end spurt). skeletal muscle is never fully recruited during any form of exercise – 35-50% in prolonged exercise and 60% during maximal efforts. To explain these and other observations, Noakes and his colleagues helped develop the Central Governor Model for fatigue. ..." source: by Todd Hargrove Thanks to the inspiration from Dr. Susann Kraeftner and her interviews with Noakes on "shift focus". --- Kjell
