Before one can answer whether or not
athletes should use protein and creatine supplements there are a number of
other questions that must first be answered. First off, what qualities define
and are important for an athlete? Physically, an athlete needs good health to
compete and outperform his opposition, whether it is outrunning a wide receiver
or setting a new max weightlifting. Mentally, an athlete needs focus and
concentration to train properly and to react quickly during competition.
Spiritually, an athlete needs indomitable perseverance to keep pushing on when
their body says stop. Being as this is a paper about supplements that only
affect the body physically, its focus will be on how creatine and protein
supplements affect athletes’ health, physiology, and performance, on the
differences between natural and supplemented creatine and protein, and what
sort of effort and nutrients the body requires to take advantage of these
supplements.
Creatine is a nutrient that is
naturally produced by and used by the human body, “nearly all of the body’s
creatine supply resides within skeletal muscle – where it assists in force generation”
(http://www.creatinemonohydrate.net/). Physiologically, as soon as the body’s always
ready but very limited supply of ATP (Adenosine triphosphate, which is the
chemical used by muscles to generate force) is used up muscle cells begin
moving the phosphate group out of stored phosphocreatine and onto ADP, yielding
ATP and creatine. “So at this point we’ve moved from 2 – 3 seconds of all-out
work (ATP) to almost 10 seconds (ATP + creatine)” (Jenkins, MD. “Creatine
Supplementation in Athletes: Review”).
The body can restore the creatine to phosphocreatine, but that process
takes about 30 seconds. Because of this it helps lifters to get a few reps of
heavy lifts or explosive movements in, “it delays the onset of muscle fatigue,
thus allows for longer and powerful workouts” (http://www.fitho.in/guide/supplements/creatine-monohydrate-supplement/)
therefore putting more rips in the muscles and making them bigger in the
restorative muscle growth period (so long as there is enough available protein
to rebuild the muscles). Creatine assists muscle building in weightlifting,
sprinting, and sports like baseball and football, but does not assist much in
endurance training because it assists in the generation of short, powerful
bursts of energy. (whentotakecreatine.org)
Creatine is usually taken “on training days… after your workout. It will
not make you nauseous and is best taken at this time in order to replenish lost
stores” (Robert DiMaggio). It is taken
post workout because it needs time to be digested in moved to a store where
your muscles can readily use it the next time they really exert themselves. A benefit
of creatine supplements being post workout powders or sometimes pills is that
one doesn’t have to worry about waiting for it to take effect or filling
themselves just before the workout with something that could make them nauseous. However Fitho (http://www.fitho.in/guide/supplements/creatine-monohydrate-supplement/)
recommends creatine monohydrate to be taken 1 hour before workout, once a day,
with 8 ounces of liquid. Creatine has water retaining properties that often
make muscles look bigger and bulkier, but when the supplement is let off, the
muscles often appear to become smaller.
Protein is used for rebuilding muscle
and tissues, red blood cells, finger nails, and for synthesizing hormones. The way muscle growth works is that when
somebody is working out, small rips are being made in the muscle fibers, that’s
partially why it hurts, and the term “no pain no gain” was coined.
“Excess protein does NOT build muscle bulk
and strength exercise does” (Jenkins, MD. “Protein Requirements for
Athletes”). A common misconception among
athletes is that taking supplements will instantly boost their muscle size,
while in reality, without a rigorous workout schedule the athlete will not see
considerable gains. Protein is the first
substance the body burns for energy, not muscle, but protein.
This is because protein cannot be stored in
the body, if it is not used it is sent to the excretory system to be
removed. People using protein powders
have to be careful that they are working extremely hard to take advantage of
it, otherwise they are sending their money down the tubes.
Dr. Mark A. Jenkins, the director of the
student health service and Team physician for Rice University
says that if a person wants to increase their
protein consumption they should “increase your intake of beans and rice, lean
beef, milk, and yogurt. It’s a much healthier (and cheaper) way to get extra
protein”.
Performance enhancing supplements are
a controversial topic, as they are surrounded by a cloud of opinions and get
huge fast scams. Some people feel that
using supplements is like cheating. Or
that it really isn’t nutritious at all, because it involves the substance being
refined, and therefore stripped of the the nutrients necessary in digesting and
making the best use of the desired nutrient. A supplement is a nutrient,
mineral, or chemical that is added to the diet, typically to make up for a
nutritional deficiency. Performance enhancing supplements are compounds
directed towards increasing athletic performance. Creatine in particular is a
nutrient believed to assist in muscle building (especially heavy sets and
explosive type exercises) and is taken regularly by many athletes and muscle
builders to build muscle strength.
Performance
enhancing supplements such as creatine and
protein require many other constituent nutrients for the body to take advantage
of them. Protein supplements consist of
protein that is stripped of its constituent nutrients— the nutrients that
normally accompany it. For example in a chicken breast there is not only
protein, but also many other nutrients that assist in its digestion and
processing. This is why whole foods are
better than artificial supplements. (Graham, Doug. MD.)
Athletes
should use creatine supplements only if they are participating in explosive
power type sports or exercise, but they should never let this become the focus
of their exercise. They are called
supplements for a reason, “something added to reinforce a whole” (http://dictionary.reference.com/browse/supplement)
as creatine supplements are not required to become strong, they assist in
giving a few more seconds of energy when
doing an short, powerful exercise. If
athletes want to add more protein to their diet they shouldn’t resort to
protein supplements, as chances are they will end up not making use of all of
the protein as the body won’t have the constituent nutrients necessary to take
advantage of it, unless they work out incredibly hard to burn off the extra
energy protein provides. It is healthier
and cheaper to instead increase the protein in one’s diet by using whole foods.
