Devices, apps, and technology for triathletes with Michael Liberzon, Andrew Buckrell and Mikael Eriksson | EP#253 

Michael Liberzon and Andrew Buckrell from the Endurance Innovation Podcast interview Mikael Eriksson on devices, apps, tools and technology that help (and those that hinder) triathletes and endurance athletes in training and racing.  

IN THIS EPISODE YOU'LL LEARN ABOUT:

-GPS-watches, bike computers, heart rate monitors, and power meters

-Advanced metrics (e.g. left/right balance, ground contact time, torque effectiveness...)

-Training planning and logging systems (Training Peaks, Today's Plan, Excel, pen and paper...)

-Heart Rate Variability, sleep tracking, and recovery monitoring

-Performance testing (lactate, VO2max, INSCYD...) 

-Aerodynamic sensors for cycling

Glycogen metabolism and optimising glycogen resynthesis with Bob Murray, PhD | EP#252

Bob Murray, PhD, did his doctorate in exercise physiology at the Ohio State University and then became a university professor. He later left academia to work in applied sports science, including 23 years as director of the world famous Gatorade Sports Science Institute, and is now an independent consultant helping businesses in the sports and fitness industry understand and leverage state of the art sports science. Recently, Dr. Murray published a review article on glycogen metabolism and resynthesis in the Nutrition Reviews journal, which is the topic of today's interview. 

IN THIS EPISODE YOU'LL LEARN ABOUT:

-When and how is glycogen (the stored form of carbohydrate in the body) used at rest and during exercise (glycogen metabolism 101)

-What is the relation between glycogen and performance?

-What is the relation between glycogen and training adaptations?

-How much glycogen do we store, and how quickly do these stores get depleted during training and racing? 

-When and why is fast and complete glycogen resynthesis important for athletes? 

-How can we influence glycogen resynthesis rates through diet, types and amount of carbohydrate replenishment, protein co-ingestion, nutrient timing etc.?

-For what level of athletes is fast glycogen resynthesis important? 

-The positive and negative effects and consequences of deliberately or unknowingly delaying glycogen resynthesis

• Can walking be used instead of low-intensity runs with similar effect, if heart rate is sufficiently elevated by walking? 
• Possible reasons for a high heart rate even when running easy, and why heart rate isn't everything
• If your VO2max is high but your threshold power/pace is poor relative to this VO2max, what sort of training is recommended? 
• Possible reasons for poor threshold relative to VO2max, and generally, limited performance capacity at submaximal intensities?
