1. What is it and where
does it come from? |
|
There is one good reason why
three out of four of the '96 summer Olympic medallists used creatine: it
works and it works well. A French scientist first discovered creatine in
1832, but it was not until 1923 that scientists discovered that over 95%
of creatine is stored in muscle tissue. The first published report of
creatine having bodybuilding effects was The Journal of Biological
Chemistry in, get this, 1926! Although we’ve known about creatine for
quite some time, the first real use of it to enhance performance was the
1992 Olympic games in Barcelona, Spain. Q: I heard that creatine and caffeine can be consumed
at the same time. But an article I read claims caffeine inhibits the
absorption of creatine into muscle tissue. Which is true?
A: There was a controversial research study published in
1996 in the Journal of Applied Physiology about creatine and caffeine;
however, if you study that article closely, you'll find that caffeine
had no effect on creatine uptake into muscle. A more recent study by
Vanakoski, et al. in 1998 investigated the pharmacokinetics of caffeine
and creatine, both alone and in combination. They reported when creatine
was used alone or even in combination with caffeine that, "creatine
was rapidly and efficiently absorbed, as reflected by plasma
concentrations." Because researchers concluded that creatine was
efficiently absorbed even when combined with caffeine, it does not
appear from the results of this study that caffeine exerts a negative
effect on the uptake of creatine into muscle tissue.
Q: I have heard conflicting information about cycling
creatine. Should I or shouldn't I?
A: Some studies support creatine cycling and others do
not. There are a couple of different "cycling" strategies you
can try: 1. Stay on creatine all the time, but reload once every six
weeks; 2. Load for a week, stay in your maintenance phase for six weeks,
then stop taking creatine completely for a couple of weeks. Repeat.
Q: I mix creatine with my workout drink in the
morning, but sometimes I don't actually finish it until several hours
later. Is creatine stable in solution this long?
A: Creatine is not totally stable in solution, so it's
definitely not a good idea to keep it mixed with liquid for days, but
there shouldn't be a problem mixing it six to eight hours before it's
consumed. Any longer than that and you may be pushing it.
Q: Creatine supplementation seems to increase muscle
strength. Would it make a person's heart stronger since it is a muscle
too?
A: Research has shown that the cardiac tissue of
laboratory animals does, indeed, take up creatine; not to the same
magnitude as skeletal muscle but to some degree. There are reports of
patients with chronic heart failure having low levels of myocardial
creatine, and in that situation, administration of creatine is
beneficial.
Q: There's been a lot of press coverage in the past
about creatine and muscle cramping. Are studies underway to investigate
this?
A: Many scientific studies have been published and
presented about creatine over the past years, and we have never seen any
scientific evidence that creatine increases an athlete's chances of
experiencing muscle cramps or "pulls." In fact, results from
one recent study conducted at the University of Memphis (entitled
"Effects of Creatine Supplementation During Training on the
Incidence of Muscle Cramping, Injuries, and GI Distress") revealed
no reports of muscle cramping in subjects taking creatine-containing
supplements during various exercise training conditions. Among the test
subjects were elite junior swimmers, college football players, and
trained and untrained endurance athletes.
Q: Is the loading phase with Creatine necessary to
experience any benefits?
A: Necessary is a rather strong word. The loading phase
is not required when using Creatine, but results of our university
studies indicate that the loading phase helps you reach that magic
muscle-creatine saturation point quicker than if you just started out
with the maintenance dose. You can reach the same creatine saturation
point by taking one serving of Creatine for 30 days as you would from
loading for 5 days, but most people aren't interested in waiting a month
for results they could see in a week or less.
Q: Are there any unfavorable effects with using
Creatine?
A: Creatine occurs naturally in many foods, with an
especially high concentration in red meats and fish. While using
Creatine, you may notice increased urination, but this is simply due to
the extra volume of liquid you'll be drinking when mixing your Creatine.
If you do not wait three to four hours between doses, you may experience
some stomach discomfort. This is easily resolved by spacing your
Creatine dosages throughout the day or cutting dosages in half for one
to two days.
Q: What is the advantage of taking creatine in a
powder versus a capsule or tablet form?
A: Powder can be absorbed by the bloodstream more
efficiently than a pill, which has a coating that must be digested
first. Also, creatine is taken in gram amounts-which means, you'd need
to take 20 1-gram capsules or 40 tablets per day to load. Needless to
say, powder is much more efficient.
Q: If I'm trying to lose fat, should I worry about
the calories in Creatine?
A: No. Creatine has no caloric value. |
