Working out on a regular basis has been gaining tenacity in recent times. From pre-workout warm-ups to post-workout energy drinks, humans want everything to complement their workout regime.
It is well-known that coffee is the best caffeine source and enables humans to go sleepless by restricting adenosine receptors and building alertness. Researches have made a ground-breaking discovery on how a caffeine stimulant can be used to burn fat.
What Does the Study Say?
The study published in the Journal of the International Society of Sports Nutrition suggests that pre-workout caffeine consumption in the afternoon can burn more fat.
The study consisted of 15 physically fit participants who were nonsmokers and free of any medical ailments. These participants were active men between the age of 25 years to 39 years who have done endurance training as part of their workout routine regularly.
The participants took a weekly test twice in the morning and twice in the afternoon, where one set of participants consumed placebos. In contrast, the other set drank FDA (Food and Drug Administration) approved level of caffeine in the ratio of 3 mg caffeine per kg in body weight and not more than 400mg exactly half an hour before exercising.
The test exercises were further divided into aerobic exercises such as brisk walking, swimming, cycling, etc., and anaerobic exercises such as weightlifting, sprinting, pushups, etc.
The study proved a significant increase in MFO (Max Fat Oxidation) and VO2max (Max Oxygen Uptake), leading to an increased fat burning rate in men who consumed caffeine pre-workout and performed aerobic exercises in the afternoon.
Participants who consumed caffeine pre-workout in the morning also had increased fat burning in comparison to non-drinkers. The level, however, was low in comparison to participants who consumed caffeine in the afternoon.
What Is the Downside?
- The test size is too small and doesn’t include women. Therefore it is not certain if pre-workout caffeine consumption will be effective for women.
- The ethnicity, race, food habits, sleep cycle, and stress level of the participants are unknown.
- Caffeine has its side effects, and it is necessary to consult with a doctor before experimenting on oneself.
- Individuals with heart ailments are not advised to consume caffeine.
- Caffeine is present in coffee, tea, energy drinks, and many others, and the study does not mention what type of caffeine should be consumed pre-workout.
