A new study by researchers in the University of Granada have suggested that drinking coffee before aerobic exercise may increase fat burning. The study was published in the Journal of the International Society of Sports Nutrition. Researchers found that if an adult drinks a strong coffee, which is considered 3 milligrams of caffeine per 1 kilogram of body weight, half an hour before exercise can have a significant influence on the rate of fate oxidation.
Furthermore, research showed that drinking coffee before exercise was most effective in the morning, as opposed to in the afternoon. The study was conducted on a cohort of men with a mean age of 32. All of the adults had no health conditions and were also non-smokers. They did exercise under four separate conditions with either a caffeine does or a placebo. Fat oxidization was most effective in the afternoon sessions, with or without caffeine. However, caffeine consumption in the morning exercise sessions resulted in a greater increase in the speed of fat oxidation, in comparison to non-caffeinated sessions.
Caffeine can be found to increase exercise performance by enhancing strength and anaerobic power during training sessions. It is a natural alkaloid that as used by both endurance and resistance athletes. However, like any drug, too much caffeine consumption can have negative side effects, such as insomnia, nausea, headaches and rapid heart rate. The Food and Drug Administration (FDA) recommend that adults who are healthy should not consume more than 400 milligrams of caffeine per day.
“The combination of acute caffeine intake and exercise at moderate intensity in the afternoon seems to be the best scenario for individuals seeking to increase the amount of fat utilized during continuous aerobic exercise,” the authors wrote. “Whether higher doses of caffeine induce greater effects on whole-body fat oxidation during graded exercise tests and further improves endurance performance remains to be investigated.”
