2007 issue now online Creatine, CLA improve muscle strength and lower body fat
in exercising seniors A report published online on October 3, 2007 in PLoS One (Public
Library of Science One) described the discovery of researchers at McMaster
University in Hamilton, Ontario that supplementing older exercisers with the
naturally occurring compound creatine monohydrate and the fatty acid conjugated
linoleic acid (CLA) results in increased muscle strength and a reduction in fat
mass compared with unsupplemented exercisers.
McMaster professor of pediatrics and medicine Dr Mark Tarnopolsky
and associates recruited 19 men and 20
women aged 65 and older to participate in a
program of twice weekly resistance exercise training. The subjects
were randomized to receive 5 grams of
creatinine monohydrate and 6 grams of CLA per day or a placebo for six months.
Participants were evaluated before and after the treatment period for strength
and muscular endurance, functional tasks, body composition, blood values,
urinary markers of compliance, oxidative stress, and bone resorption. At the end of the 24 week period, functional
capacity, as measured by tests involving walking, balance, sitting, standing,
and stair climbing, showed improvement in both groups. Additionally, oxidative
stress was reduced. Strength, measured by a variety of tests, also improved in
all participants, however, among subjects that received creatine and CLA there
were greater gains in muscle endurance, as well a significant increase in fat
free mass and body fat loss compared
with the placebo group. The trial builds on a study conducted by Dr Tarnopolsky
and Dr S. Melov at the Buck Institute of Age Research published in the same
journal earlier this year, which found that six months of resistance exercise
reversed some aging-associated muscle gene expression abnormalities. His data
confirms that supervised resistance exercise training is safe and effective for
increasing strength and function in older adults and that a combination of
creatine monohydrate and CLA can enhance some of the beneficial effects of
training over a six month period,?Dr Tarnopolsky concluded. Health Concern Exercise
enhancement Exercise is a proven life
extender. Thousands of clinical trials have documented the benefits of
a regular exercise program. It has been
shown to reduce the risk of many
diseases, including heart disease, the leading killer in the United
States It is effective in preventing obesity and depression, and it helps
people of all ages maintain flexibility, strength, and even independence. Yet
many people who exercise regularly aren't getting all the benefits they could
from their program, and some wonder why they never seem to make any progress at
the gym. The fact is, although any sustained exercise is helpful, results are
about more than the time spent in a gym or jogging on a treadmill. That only
half the picture. Nutrition is a critical component of any exercise program,
and there are proven ways to maximize your exercise program that you might not
hear about from your family physician or
from the government. Studies show that creatine supplementation effectively
increases lean muscle mass and strength (Nissen SL et al 2003; Kreider RB 2003;
Gotshalk LA et al 2002). Creatine donates a phosphate molecule to adenosine
diphosphate in order to produce more ATP for energy demands. The buildup of
lactic acid may also be delayed after creatine supplementation.> Studies support
the use of creatine to increase strength in older people (Gotshalk LA et al
2002; Chrusch MJ et al 2001). Other studies demonstrate that creatine can Help
those with degenerative neurological disorders and enhance memory in older
adults (Wyss M et al 2002; Beal MF 2003; Tarnopolsky MA et al 2001; Matthews RT
et al 1998; Tabrizi SJ et al 2003; Laakso MP et al 2003; Yeo RA et al 2000;
