Sports Drinks, Bars, Or Gels:
Which Are Best?
There are so many products out there that claim they will enhance
athletic performance. Three commonly used products are: sports drinks,
energy bars, and energy gels. Are there benefits to using one over
the other? Let's take a look . . .
Research has been done on all of the above products. Keep in mind;
however, there are many brands of each product, and research may
not have been conducted on all products sold. In general, using
a sports drink has been shown to not only improve performance, but,
in one study, runners who drank the sports drink ran faster and
felt that the race was easier compared to runners who drank a placebo.
Note: It is important that a placebo is used in studies in order
to be sure that the changes that a researcher observes are due to
the effects of the intervention, not just by chance.
As far as energy gels are concerned, research has also shown that
they may be helpful for athletes, too. A recent study conducted
at California State University at Sacramento compared the use of
a gel to a placebo. Although the researchers did not assess performance,
they did report that there were higher levels of blood glucose (sugar)
in the athletes who consumed the gel compared to the placebo group.
One can speculate that this higher blood glucose will be used for
energy, and thus, spare stored carbohydrate, called "glycogen
", in the muscle. Since the gels do not provide fluids, it
is important to drink plenty of fluids, as well.
How do energy bars rate? Well, several researchers have investigated
the effectiveness of solid versus liquid carbohydrates. It doesnít
seem to matter if you take in solid or liquid carbohydrates, but,
it does matter that you also drink water with solid carbohydrates.
If athletes like the taste of energy bars, it may be worthwhile
for athletes to try them; since they are convenient and athletes
can keep several energy bars in their sports bag for quick energy
boosts.
