When taking supplements during your
workout, you can find many of the ingredients in pre-workout supplements the
ones that research has shown to improve performance, like caffeine or nitric
oxide in real foods, too. Plus, with those real foods, you also get other good nutrients
for you. Dieticians recommend a 'food
first' approach for both recreational and extreme athletes who are looking to fuel
their workouts. Real foods, rather than powders or supplements, are ideal
because they offer the best variety of macro and micronutrients, tend to be
easiest to digest, and are more palatable. Also, they recommend that keeping it
simple with a snack one to two hours before a workout, making sure endurance
athletes get a heavy serving of carbohydrates and weightlifters get a combo of
carbs and protein. Watch the fiber and fat, as you'll digest those more slowly,
which could lead to digestive discomfort. To make it clear, protein and a
fast-digesting sugar to spike insulin should be on your list. Additionally,
there are a few other ergogenic supplements you should consider.
Typical needs for using a pre-workout
supplement:
Whey Protein Isolate (WPI)
Whey is the protein that's separated from
the curd in the production of cheese. The best forms of WPI have limited fat
and lactose; production processes like cross-flow microfiltration have helped
in its purification. WPI is absorbed quickly and provides a steady stream of
amino acids which enter the blood quickly. This has been shown to promote gains
in lean mass and strength, reductions in body fat, and increased growth hormone
release.
Creatine
From meat sources, creatine has been shown
to increase protein synthesis by pushing water into muscle cells. It's also
been shown to increase phosphocreatine stores in muscle tissue, which is used
to make more energy for longer and more intense workouts. Research also
indicates that creatine elevates insulin-like growth factor, an anabolic
hormone.
Glutamine
Glutamine is important for protein
synthesis and is often depleted during heavy exercise. Research has shown that
supplementation increases muscular growth by boosting muscle cell volume and
growth hormone release, while also reducing catabolism.
Caffeine
A stimulant that helps mobilize fat cells
into the bloodstream, caffeine has been shown to increase muscle strength and
intensity when taken pre-workout. Besides boosting metabolism, caffeine has
also been shown to reduce post-workout muscle soreness by 50 percent.
Sugar
Fast-digesting
carbs like sugar, dextrose, and maltodextrin quickly spike insulin levels,
helping drive all the other ingredients in your post-workout shake into
glycogen-depleted muscle tissue. Of note, since fructose must be broken down by
the liver, it's not as fast as these other sugars.
If you're a recreational exerciser, you
probably don't need a pre-workout supplement. Beet juice, whole-food protein
sources, and natural caffeine sources like tea or coffee can likely provide the
benefits you're looking to achieve when taking a pre-workout supplement but
without the risk. A great pre-workout supplement should do all of the above,
but it should do so without the addition of unnecessary artificial colors,
flavors and sweeteners that are often used to mask the inherently bitter or
sour taste of many of the ingredients
