We are honored to talk about sweet spot training with Dr. Andy Coggan, Ph.D on this podcast.  Dr. Coggan is an Associate Professor of Kinesiology at Indiana University’s School of Health and Human Sciences.  IU has a doctoral program in Kinesiology so if there’s a young cyclist out there that wants to study how to get faster, IU’s Department of Kinesiology could be the place for you.

Andy and Frank go way back to the early days of USA Cycling Coaches Education Program primarily from the power based training seminars and clinics.  In 2004 Andy presented at the Coaches Summit at USA Cycling’s headquarter’s in Colorado Springs, CO and introduced a power based impulse – response performance model. The term sweet spot training was born a few months later from a group of coaches working to validate the model which would later become the Performance Manager Chart in TrainingPeaks and WKO. Andy is also the co-author of “Training and Racing with a Powermeter” along with Hunter Allen.

Of course we reference the sweet spot graph, address the arbitrary units from the y-axis and the expected physiological adaptations from training in Zones 1 – 7.

We also reference two important OG exercise physiology studies here:

Effect of training on enzyme activity and fiber composition of human skeletal muscle Gollnick PD, Armstrong RB, Saltin B, Saubert CW 4th, Sembrowich WL, Shepherd RE. J Appl Physiol. 1973 Jan;34(1):107-11.

Linear increase in aerobic power induced by a strenuous program of endurance exercise. Hickson RC, Bomze HA, Holloszy JO. J Appl Physiol Respir Environ Exerc Physiol 1977 Mar;42(3):372-6.

You can read about and listen to the story behind the performance manager chart, TSTWKT,  here.
