Genetic polymorphism on the effect of oral caffeine intake on fat oxidation during exercise has been studied in active and healthy population performing an incremental test on a cycle ergometer with 3-min stages at workloads from 30 to 70% of maximal oxygen uptake (VO2max). Participants performed this test after the ingestion of a) placebo; b) 3 mg/kg of caffeine; c) 6 mg/kg of caffeine. Fat oxidation rate during exercise was measured by indirect calorimetry. The influence of the CYP1A2 c.-163A>C, GSTP c.313A>G and PGC1a polymorphisms was evaluated to determine the effects on fat oxidation during exercise
