Summary
This study looked at whether a person's genes (specifically the CYP1A2 gene) change how caffeine affects their strength training over 8 weeks. 48 healthy, active adults took either caffeine or a placebo before each workout. Researchers measured things like lifting speed, power, and muscle changes to see if genetics play a role.
