Andrew Coggan, Ph.D.

Andrew R. Coggan, Ph.D., is an internationally-respected exercise physiologist who has published numerous scientific articles on diverse topics such as the effects of carbohydrate feedings on cycling performance, the physiological adaptations to endurance training, and the effects of aging on muscle metabolism during exercise. A national-caliber masters cyclist, he is also widely recognized as one of the leading experts on the use of power meters in training. His prolific posts to the "wattage" group hosted by Google and to other Internet forums have enlightened many about the physiology of exercise and training in general and the use of power meters specifically. In particular, Normalized Power(tm), Intensity Factor(tm), Training Stress Score(tm), Power Profiling?, Quadrant Analysis?, and the Performance Manager? chart featured in the WKO+ software are ideas that he developed specifically as a result of his interactions with, and to meet the needs of coaches such as, Hunter Allen. As a result of his contributions in this area, in 2007 he was honored by USA Cycling with their Sport Science Award and named a Finalist by the US Olympic Committee for their Doc Councilman Award.
