Performance in most endurance events is determined by the maximal sustained power production for a given competition distance, and the energy cost of maintaining a given competition speed. Strength training could thus contribute to enhance endurance performance by improving economy of movement, delaying fatigue, improving anaerobic capacity and enhancing maximal speed. In this session, Iñigo will outline the scientific basis of strength training for endurance performance; the mechanisms for strength-training-induced endurance gains; the methods and the nutritional recommendations to optimize concurrent strength and endurance training. BIO: Iñigo earned his PhDs in Biology of Muscular Exercise (University of Saint-Etienne, France) and Physical Activity and Sport Sciences (University of The Basque Country). He is a Level III swimming and triathlon coach. His research interests include training methods, recovery, tapering, detraining and overtraining. Iñigo has performed extensive research on professional cycling, swimming, running, triathlon, rowing, tennis, football and water polo. He has published over 100 articles in peer reviewed journals, five books and 30 book chapters, and has given over 300 lectures in international conferences. Iñigo has been a senior physiologist at the AIS, Euskaltel-Euskadi Pro Cycling Team, Athletic Club Bilbao professional football club, Araba Sport Clinic and the Spanish Swimming Federation. He is now associate professor at the University of the Basque Country, associate researcher at Finis Terrae University in Chile, and associate editor for the International Journal of Sports Physiology and Performance.
