Podcast with Eric Trexler

Eric Trexler is a PhD student at UNC Chapel Hill, with a research focus on how exercise and nutrition affect metabolism, performance, and body composition. Eric comes from a background in natural bodybuilding, powerlifting, and strength coaching, and currently holds certifications in sports nutrition (CISSN) and strength and conditioning (CSCS). Eric completed his undergraduate degree at The Ohio State University, and his master’s degree at UNC Chapel Hill. Eric serves as a reviewer for multiple academic journals and has written numerous lay press and peer reviewed articles related to physique and performance enhancement. 






In this podcast, Eric and I discussed the following topics

1.What does caffeine actually do in the body?

2. Caffeine is a very popular substance to use for increased performance. Is there any difference if you ingest caffeine from liquids like coffee etc. or from supplements?

3. What seems to be the optimal dosage to ingest caffeine pre workout and how long is the half-life? 

4. Can you develop a tolerance for caffeine if you chronically consume it?

5. For many years, there has been a lot of talk about caffeine potentially lowering the effect of creatine. You recently did a study looking at this. Could you explain what the aim of the study was, how it was designed, what the results where and what practical implications this study has?
