S2E34: HIIT Science, Physiology First & Weapons of Mass Destruction w Prof. Paul Laursen PhD

SEASON 2, EPISODE #34

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. 

About Pro. Paul Laursen

Across the last two Olympic cycles, Dr. Laursen was employed as Lead Physiologist for High Performance Sport New Zealand alongside a joint position as Adjunct Professor of Exercise Physiology at Auckland University of Technology. This unique role positioned him at the nexus between theory, research and application of sport science and physiology for Olympic sports in New Zealand. While he continues his Professorial role, he is now based in Canada as a coach and consultant (www.plewsandprof.com). He’s amounted more than 125 scientific publications. He’s personally competed in 17 Ironman triathlon events, including Hawaii, with a personal best time of 9:57. Follow Prof Laursen on Twitter @PaulBLaursen and @HIITScience.

S2E33: Fueling Endurance Athletes & Periodizing Body Composition w/Dr. Trent Stellingwerff PhD

SEASON 2, EPISDOE #33

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.

S2E18: Fasting Glucose, Inflammation, Keto & HIIT w/ Alessandro Ferretti

Season 2 Episode #18

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.

S2E7: Ketone Supplements & Endurance Exercise Performance with w Dr. Brianna Stubbs PhD

SEASON 2, EPISODE #7

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!

About Dr. Brianna Stubbs

Dr. Brianna Stubbs is a British rower and research scientist who won two gold medals for Great Britain at the 2013 and 2016 World Rowing Championships. She was the youngest person to row across the English Channel when she completed the feat in 2004, at the age of 12. Her research is focussed on ketone metabolism in athletes, the effects of different ketone supplements on human physiology, and the effects of ketone drinks on appetite.
