Gareth Sandford, PhD, is a physiologist at the Canadian Sports Institute Pacific. He has worked across 15 individual and team sports within three Olympic systems (UK, New Zealand and Canada) and three professional sports leagues (English football, cricket and rugby), supporting over 400 athletes that achieved 18 Olympic, Paralympic and World Championship medals and one world record. In this interview we discuss athlete profiling using the Anaerobic Speed Reserve, and how to optimise the training process for different types of athletes.    IN THIS EPISODE YOU'LL LEARN ABOUT: -Athlete profiling and testing -Endurance, Hybrid, and Speed profiles and their unique characteristics -What is the Anaerobic Speed (Power) Reserve, and its underlying determinants? -How to improve sprinting speed or peak power -When and how to train for strengths and weaknesses -Why doing a lot of high intensity training can hinder rather than help the athlete -Critical Speed (Power) training   SHOWNOTES: https://scientifictriathlon.com/tts398/   SCIENTIFIC TRIATHLON AND THAT TRIATHLON SHOW WEBPAGE: www.scientifictriathlon.com/podcast/   SPONSORS: Precision Fuel & Hydration help athletes perform at their best through their online tools, patented Sweat Test and range of electrolytes and fueling products.
