Barcelona: Caffeine – about 3 milligrams per kilogram (mg / kg), equivalent to a strong coffee – increases the fat-burning rate half an hour before aerobic exercise, a new study suggests.
The study, published in the Journal of the International Society of Sports Nutrition, also found that if exercised in the afternoon, the effect of caffeine was greater than in the morning.
“The results of our study showed that acute caffeine ingestion increased maximum fat oxidation during exercise 30 minutes before performing an aerobic exercise test,” said lead researcher Francisco Jose Amro-Gahette of the University of Granada, Spain.
For the study, researchers aimed to determine whether caffeine – one of the most consumed ergogenic substances in the world – to improve sports performance – actually oxidized during exercise or “burned” fat. Enhances
A group of men with an average age of 32 years completed an exercise test four times at seven-day intervals. Subjects ingested 3 mg / kg caffeine or a placebo at 8 am and 5 pm (each subject completed the tests in all four conditions in a random order).
The condition before each exercise test (hours ending after the last meal, physical exercise, or intake of stimulants) was strictly standardized, and oxidation of fat during exercise was calculated accordingly.
In summary, the findings of this study suggest that a combination of moderately intense caffeine intake and aerobic exercise in the afternoon provides the optimal scenario for those wishing to increase fat burning during physical exercise.
