S2E44: Effect of Caffeine Intake on Muscle Strength and Power w Jozo Grgic PhD

SEASON 2, EPISODE #44

Dr. Bubbs sits down with expert Jozo Grgic PhD, to talk about the effects of caffeine intake on resistance training. Jozo outlines the mechanisms of how caffeine may impact strength and power-based training, lower-body versus upper-body movements, as well as its effects on pain and hormone response to training. He also discusses the caffeine dose ranges, coffee versus caffeine supplements, what the research says for female athletes and the effects of caffeine gum on performance. Jozo also shares how caffeine impacts blood pressure and his thoughts on the evolution of caffeine research.

S2E35: NBA Pre-Season, The Athlete Heart & Cardiovascular Disease w Tony Manci MS

SEASON 2, EPISODE #35

Dr. Bubbs talks heart health, cardiovascular screening and the “athlete heart” with clinical physiologist Tony Manci MS. In this episode, Tony will discuss hypertrophic cardiomyopathy (HCM) and sudden cardiac death in athletes, the difference between “athlete’s heart” and heart disease, and outlines an NBA pre-season cardiovascular screen. Tony also discusses the impact of a sedentary lifestyle on heart and vascular health, highlights modifiable risk factors to reduce your likelihood of heart disease, and shares his favourite strategies to build aerobic fitness. He also talks about the power of habits and the evolution of HCM research.
