S2 EPISODE 47 - Effect of Caffeine Intake on Muscle Strength and Power w/ Jozo Grgic PhD(c)

Season 2 Episode 47, Dr. Bubbs sits down with expert Jozo Grgic PhD(c) 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.

S2 EPISODE 14 - The Opioid Epidemic, Meditation & Managing Chronic Pain w/ Dr. Abhimanyu Sud MD

In Season 2 Episode 14, Dr. Bubbs sits down with expert Dr. Abhimanyu Sud MD to talk about managing chronic pain and today’s opioid crisis. In this episode, Dr. Sud will share staggering statistics on the scope and intensity of today’s opioid epidemic, what’s driving the opioid crisis, the research evidence supporting the use of opioids for treating long-term pain, as well as the impact of opioids in sports – in particular contact sports like hockey and the NFL – and how meditation can alter areas of the brain that impact pain intensity and pain suffering. Dr. Sud also provides tips on meditation and shares insights into his routine. Make sure you listen to this fantastic episode!

Lay-Ups In This Episode

1)  More people dying in current opioid epidemic than at the height of the opioid crisis.

2)  The evidence-based research on the use of opioids for chronic pain management is very poor (despite their widespread use).

3)  Meditation can alter regions of the brain that control pain intensity and pain bothersomeness.
