Can caffeine increase the use of fat for fuel in the muscles?

Prior to athletic events that require long term energy some(not all)cyclist and endurance athletes will consume caffeine to help with fat burning for fuel. This practice may not be safe but is done to increase the use of fat used for fuel in the muscles. In order for this to occur, it will depend on the amount of fatty acids released from adipose stores into the blood supply. Athletes will attempt to increase the release of fatty acids into the blood by consuming caffeinated beverages. This practice does work successfully by increasing fatty acid release from adipose depots thus allowing the athlete to more efficiently use fat for energy in the muscles. Keep in mind that when competing this practice is considered illegal under the National Colligate Athletic Association if the amount of caffeine in the blood exceeds the equivalent of 6-8 cups (8oz.per cup) of coffee. Other risk that are involved with this type of practice are high amounts of caffeine can affect the heart negatively by increasing blood pressure, heart arrhythmia and cause blood glucose levels to drop. People who are sensitive to caffeine should avoid this practice.

In my opinion, I don’t recommend this. In fact, good old fashion hard work will not only suffice but also give you a sense of accomplishment and self-efficacy.
