USN ZMA (120 Capsules) (3 pot saver)
I (Matt) am not entirely sure why USN suggest supplementing their ZMA prior
to training, as well as bedtime (normal suggestion). As mentioned on the comments
of Maximuscle's ZMA, I have supplemented ZMA (and Magnesium separately) on numerous
occasions - usually when dieting. I sleep very deeply after supplementing it
(before bedtime), which is obviously beneficial for recovery. Frank Zane (ex
Mr Olympia) was an advocate of supplementing Magnesium after his first session
of a double split to enable him to sleep between workouts. Maximuscle ZMA is
fairly cheap for potentially very good results, so it comes highly recommended!
WHAT USN HAVE TO SAY:
USN's ZMA is produced using high levels of the original, patented ZMA powder
that has become a number one supplement used by strength and power athletes,
bodybuilders and endurance athletes. Research shows that this blend of nutrients
raises low testosterone levels, increases strength, and accelerates gains in
muscle size. One university study showed a 30% increase in testosterone levels
following ZMA supplementation.
Deficiencies in Zinc and Magnesium are common in athletes. This results in
reduced testosterone levels, lack of performance, reduced recovery, cramps and
tiredness. USN's ZMA contains a powerful combination of ZMA powder and vitamins
to help combat these deficiencies. ZMA can be used by all athletes wanting to
gain lean muscle size and strength, including bodybuilders, rugby players, sprinters
and other strength athletes. ZMA is also used widely by endurance athletes,
such as runners, cyclists and triathletes, as it helps to prevent the drop in
testosterone levels linked with high volumes of training.
ZMA increases insulin-like growth factor-1 (IGF-1) which stimulates growth
and development of muscles by increasing the uptake of glucose and amino acids
into cells. Studies show that ZMA increases muscle strength by around 11%, resulting
in rapid gains in muscle size. ZMA has also been to shown to improve sleep patterns
when taken 30 minutes before bed, resulting in increased muscle growth.
Many studies show that most athletes are deficient in zinc, magnesium and vitamin
B6. A zinc deficiency results in decreased muscle endurance and lowered total
work capacity of muscles. Regular exercise results in decreased zinc and magnesium
levels, therefore requiring supplementation.
The minerals zinc and magnesium have a number of important functions in the
body. Zinc has been strongly linked to the production of testosterone, a hormone
that plays a vital role in regulating muscle growth. In addition to its effect
on testosterone, zinc has also been shown to increase levels of growth hormone
and IGF-1. Both are essential for increasing muscle size. Magnesium is also
an essential mineral that is involved in more than 300 chemical reactions in
the body including the oxidation or ‘burning' of fat.
Unfortunately, most people don't get enough of these minerals in their diets.
Clinical trials show that animals fed low zinc diets exhibit little muscle growth
at all. If you exercise, the problem can be made worse, as just one training
session can increase magnesium losses by 21%. These deficiencies have led researchers
to study mineral supplementation in some depth, with some extremely promising
results. Magnesium increased muscular performance far more quickly than in those
taking a 'dummy' supplement. Similar findings are reported for zinc. After just
14 days of supplementation, subjects showed an impressive increase in muscular
strength and endurance. Even in men just moderately deficient in zinc, 30 milligrams
daily was enough to double testosterone levels in only six months.
Results have been even more impressive when a zinc and magnesium combination
has been used. In one study, two groups of American Footballers took part in
an 8-week training program. One group was given ZMA, while the second group
used a 'dummy supplement. None of the footballers knew which was which. ZMA
supplementation led to a 33.5% increase in testosterone. In contrast, testosterone
levels actually dropped in the control group. IGF-1 (a powerful hormone that
plays a vital role in muscle growth) is normally lowered in response to regular
exercise. Yet, despite the intensive training program, ZMA users experienced
a 3.6% increase in IGF-1 levels. In non-ZMA users, IGF-1 levels dropped by a
21.5%. These powerful effects on hormone levels also had an impressive effect
on muscle strength - ZMA users demonstrated gains in strength that were 252%
larger than the control group.
