The Stronger By Science Podcast Creatine, Genetics, and Dr. Peter Fitschen
High Caffeine Can Interfere With Creatine Loading
- Very high ergogenic caffeine doses may blunt creatine's performance benefit during loading.
- Typical coffee-level caffeine is much smaller than the ergogenic doses used in those studies.
Perception Of Genes Can Alter Physiology
- Perceived genetic risk can change both perceptions and physiology.
- Telling people they have a 'good' or 'bad' gene often affects outcomes more than the actual genotype.
Don't Overread Consumer Gene Tests
- Don't overinterpret direct-to-consumer genetic tests for athletic potential.
- Avoid catastrophic conclusions from single-locus results like ACTN3.
