Coffee Before Exercise Increases Fat Burn
A new research study[1] shows that caffeine improves the maximal fat oxidation (MFO) rate and aerobic capacity, which are lower in the morning than in the afternoon. The result of the study validates the earlier reported diurnal variation in the whole-body fat oxidation rate during graded exercise in active caffeine-naïve men and shows that the acute ingestion of 3 mg/kg of caffeine boosts MFO, Fatmax, and VO2max independent of the time of day. What was the Goal of the Research Study? Metabolic flexibility has lately been proposed as an additional key factor influencing performance in endurance exercises. Athletes’ endurance is lower early in the morning and late at night than in the afternoon, and that MFO and Fatmax are higher [Read more …]
