S2 EPISODE 44 - Athletes, Exercise Immunology & Immuno-Nutrition w/ Dr. David Pyne PhD

Season 2 Episode 44, Dr. Bubbs interviews expert physiologist Dr. David Pyne PhD to talk exercise immunology and keeping athletes cold and flu free. In this episode, Dr. Pyne reviews the fundamentals of immunology and how the immune system is regulated by exercise and nutrition. He’ll discuss how training volume, intensity and load impact immunity, and more importantly, why keeping athletes cold and flu free is paramount for athletic success. Dr. Pyne also discusses the key immunity biomarkers and how effective they may (or may not) be at flagging at-risk athletes. Finally, he dives into the topic of immune-nutrition and how the food you eat, and supplements like probiotics, can impact athlete immunity and therefore ability to train and compete.

S2 EPISODE 19 - High-Dose Omega-3, CBD Oil & Concussions w/ Dr. Michael Lewis MD

In Season 2 Episode 19, Dr. Bubbs interviews Dr. Michael Lewis MD to discuss the applications of high-dose omega-3 supplementation in concussions. In this episode, Dr. Lewis reviews the pathophysiology of concussion and how it unfolds in two distinct phases, which athletes are at the highest risk of concussion, his research into the use of high-dose omega-3 for concussion in the military, protocols for omega-3 use with concussion, as well as the novel application of CBD oil for head trauma and mental conditions. 

Lay-Ups In This Episode

1)  In the general population, young children and the elderly are at the highest risk of concussion from falls.

2)  Concussions unfold in two distinct phases: the trauma and the subsequent biochemical cascades.

3)  High-dose omega-3 supplementation may help to accelerate recovery from brain trauma.

S2 EPISODE 17 - Dietary Supplements & The High Performance Athlete w/ Prof. Stuart Phillips PhD

In Season 2 Episode 17, Dr. Bubbs interviews world expert Professor Stuart Phillips PhD to talk about his contribution to the International Olympic Committee's (IOC) recent research and consensus statement on the use of supplements in sport. In this episode, Stu discusses athlete rationale and motives for using supplements, caffeine dosing strategies for endurance based exercise versus repeated sprints, the application of dietary nitrates and what exercise duration benefits most, as well as evidence-based immune support supplements (sharing which are more hype than substance). Stu also outlines supplements that indirectly support performance via improving capacity to train or recovery such as HMB, omega-3s, and collagen supplements, as well as the  ‘decision making’ tree to help coaches, athletes and practitioners figure out how to best apply supplement strategies.

Lay-Ups In This Episode

1)  Supplements can impact performance directly, or indirectly via supporting improved training and/or recovery.

2)  Supplements can help athletes get that extra 2-5% of the performance or recovery gains.

3)  Always ensure you use NSF or Informed-Choice supplements or from certified WADA approved labs.
