Professor David Bishop is a world leader in muscle exercise physiology with more than 250 publications to date. He explains how high training volume and high-intensity training each leads to particular endurance adaptations on a cellular and mitochondrial level. Knowing about these adaptation pathways and effects of different training methodologies is essential for triathletes and coaches when planning out their training.    IN THIS EPISODE YOU'LL LEARN ABOUT: -The difference between mitochondrial content and mitochondrial function -How high-volume training skews towards increased mitochondrial content, and high-intensity training towards improved mitochondrial function -Mitochondrial content may be the more important adaptation of the two when it comes down to performance -Different intensity levels and their benefits and drawbacks -Guidelines on appropriate Training Intensity Distributions  -"Training Low" - adaptations to training with low glycogen stores   SHOWNOTES: https://scientifictriathlon.com/tts215/   THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com   SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
