S2 EPISODE 37 - HIIT Science, Physiology First & Weapons of Mass Destruction w/ Prof. Paul Laursen PhD

Season 2 Episode 37, Dr. Bubbs interviews renowned sport scientist and coach Professor Paul Laursen PhD to discuss the science and application of HIIT training. In this episode, Prof Laursen outlines his new collaborative project HIIT Science and dives into key principles for programming HIIT training for individuals and team sport athletes. He kicks things off by addressing the importance of understanding the demands of the sport and the athlete profile. Laursen then shares the three main areas that can be targeted with HIIT training: aerobic, anaerobic and neuromuscular, and the five different types of HIIT training formats. He also outlines the pitfalls of thinking “format first” (i.e. the workout) and emphasizes the importance of thinking “physiology first” when programming training sessions for individuals and teams. Phenomenal insights from Prof Laursen and an exciting new educational resource for practitioners and athletes.

S2 EPISODE 36 - Fueling Endurance Athletes & Periodizing Body Composition w/ Dr. Trent Stellingwerff PhD

Dr. Bubbs interviews renowned physiologist Dr. Trent Stellingwerff PhD to discuss Eliud Kipchoge's record-breaking performance at the Berlin Marathon and the fueling strategies of elite marathoners. He also talks about the role of glycogen availability as a training regulator and the purposeful application of low carb availability training sessions in elite performers. As well, Trent dives into his past research into body composition periodization in endurance athletes and how it can impact athletic performance, injury risk and illness over a career. He shares insights into daily caloric restriction and weekly bodyweight loss targets as well as factors to consider before implementing this strategy with athletes. Finally, Trent shares his tips for recreational runners on improving performance and health and avoiding the trap of trying to ‘fuel like the pros’. Fantastic insights from a world-leader!

S2 EPISODE 20 - Fasting Glucose, Inflammation, Keto & HIIT w/ Alessandro Ferretti

Season 2 Episode 12, Dr. Bubbs sits down with Alessandro Ferretti to discuss the role of fasted morning glucose as a marker for health, recovery and longevity. Alessandro outlines what impacts your fasting glucose marker, when and how to measure, and some pitfalls of over-interpretation. Alessandro also discusses his recent research with Dr. Daniel Plews and Prof Paul Laursen on the effects of a ketogenic diet on HIIT training performance and the keys of how to interpret them into your practice.

Lay-Ups In This Episode

1)  Higher morning fasting glucose is associated with higher all-cause mortality.

2)  Chronic inflammation levels in athletes can hamper recovery and adaptation.

3)  Ketogenic diets do not hamper HIIT training over the course of 4-weeks in moderately fit endurance athletes.

S2 EPISODE 8 - Ketone Supplements & Endurance Exercise Performance with w/ Dr. Brianna Stubbs PhD

In Season 2 Episode 8, Dr. Bubbs interviews ketone expert Dr. Brianna Stubbs PhD to discuss the impact of supplemental ketones on endurance exercise performance. In this episode, Brianna explains the differences between endogenous and exogenous ketosis, the anti-inflammatory and antioxidant effects of ketones, and the impact of ketone supplements on blood glucose and lactic acid levels, as well as endurance time-trial performance. She also discusses research on exogenous ketone effects on satiety and potential implications for weight loss. Fantastic insights here from Brianna!
