Bent Rønnestad, PhD, is a professor at the Inland Norway University of Applied Sciences. Bent has been heavily influential in the sports science world in areas such as concurrent training, high intensity interval training, periodisation, and heat training.         IN THIS EPISODE YOU'LL LEARN ABOUT: -Is time near VO2max a good indicator for the effectiveness of an interval workout?  -Different types of interval sessions: short intervals, traditional long intervals, fast start long intervals, and variable long intervals -How do the above types of sessions compare for acute responses (e.g. time at VO2max) and for training adaptations and performance improvements?  -Periodisation of interval training -An overview of heat training and adaptations in both hot and temperate conditions -Specific protocols used to increase hemoglobin mass, markers of performance and performance, and maintenance protocols -For whom is heat training a recommended? -How does heat training compare to altitude?    SHOWNOTES: https://scientifictriathlon.com/tts386/   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.
