Q&A #89 - Typical training week structures; Frequency and load of hard workouts; Stacking hard workouts; Intensity control during swimming What would be some good starting points for a weekly training structure? How many hard workouts is reasonable to include, and how much of a training load should they comprise? Does the load of hard workouts differ between triathletes and single-sport athletes? Can stacking harder workouts be a good strategy to get more relative rest between hard days? How can adult-onset swimmers in particular maintain intensity control and avoid overloading too much when it comes to swimming?

Professor Louise Burke is Head of Sports Nutrition at the Australian Institute of Sport (AIS). Through her career she has worked both practically with applied nutrition science as well as deep in academia, so she has a great perspective on both ends of the spectrum. In recent years, much of her research has been focused on investigating the effects of low-carbohydrate, high-carbohydrate, and periodised carbohydrate dietary interventions on endurance performance. This research is the topic of today's discussion. IN THIS EPISODE YOU'LL LEARN ABOUT: -The "Supernova" studies - comparing the effects of low-carbohydrate, high-carbohydrate and periodised carbohydrate intake on endurance performance -How quickly does it take to get fat-adapted? -The impact of fat adaptation on fat oxidation and performance -Why a constant high-carbohydrate diet outperformed the more sophisticated periodised carbohydrate diet SHOWNOTES: https://scientifictriathlon.com/tts236/ THAT TRIATHLON SHOW HOMEPAGE: www.thattriathlonshow.com SPONSORS: Precision Hydration - One-size doesn't fit all when it comes to hydration.
