A
few months ago when Jeff DuPonte noticed the
oh-too-familiar cramps beginning to grip his thighs, his whole family raced into
action. For 20 minutes his wife and daughters worked at a
near-frantic pace, kneading the tightening muscles in his
arms and legs and applying heating pads and blankets.
Simultaneously, Jeff swallowed several large glasses of
water, along with a mixture of cornstarch and water and
bites of white rice.
“It was truly amazing how
effective this strategy was,” says Jeff in retrospect.
“I was not only better in an hour, but I was up and
walking within two hours and had a normal next day.”
Since this episode, Jeff has had another “chance” to
try his combined method of massage, heat and
carbohydrates
and it worked equally well the second time. “Granted
these attacks were only a 6 on a scale of 10, but I wouldn’t
hesitate to try it again,” he says. “The longer one
goes in an attack—and we are talking minutes here—the
more the muscle shrinks and hardens.”
Jeff’s experience raises
some interesting questions. Why was this combo so much
more effective than carbohydrates alone? What does massage
accomplish in muscle? Why do so many athletes, coaches and
trainers believe massage aids in muscle recovery? Are
there any potential dangers in using massage during an
attack of muscle breakdown caused by CPT II deficiency?
For answers, we turned to
expert Peter Tiidus, Ph.D., a Canadian researcher who has
studied exercise-induced muscle damage. “We do know that
massage is unlikely to have any great influence on blood flow in relaxed muscles of healthy
individuals, and will probably not increase oxygen or fuel delivery to these muscles,“ says Tiidus.
“However, it is certainly possible that massage can decrease spasms, and this would aid in the
return of blood flow.”
In addition to damage from
low levels of ATP (fuel), the
cramps that occur in CPT II
deficiency can block blood flow to the muscle and lead to
more damage, says Tiidus. Then when blood flow is restored, a third type of damage occurs known as
reperfusion injury. Research suggests that this third type
of injury is caused by free radical generation. Tiidus
notes that the longer the blood flow to muscle is blocked, the greater the injury. Therefore,
any technique that could potentially reduce spasms or
cramps would have the potential to reduce cumulative
muscle injury.
What about potential damage
from the massage itself? “If the massage is relatively
gentle and is started immediately at the onset of cramping, then it
is unlikely to be harmful,” says Tiidus. However, he cautions that high-pressure massage used later
in an attack of muscle breakdown could manually damage the
muscle.
Jeff DuPonte agrees. “I
look at this as a rehab measure, except preemptive,” he
says. “But you need to know the difference between a severe case and
a lesser attack. It all depends on a good deal of common sense and judgment.”

MASSAGE
Two massage techniques
are commonly used in athletic settings for their potential
restorative effects on muscle.
EFFLEURAGE
Includes both light and deep muscle stroking in the
direction of blood and lymph flow, i.e. towards the heart.
The goal is to relax the muscle and reduce any excess
fluid accumulation.
PETRISSAGE
Involves muscle kneading and rolling performed with the
palms or heels of the hands, or tips of the fingers. The
goal is to decrease muscle spasms.

When
college-student Kristina Olsen feels the first twinge of
muscle pain, she reaches for her B-D®
glucose tablets.
“My doctor and my dietician decided that I should keep
glucose tablets or Insta-Glucose™ with me at all times,”
she says. “I am to take it the minute I feel any muscle
pain.“
One orange-flavored B-D® glucose pill delivers 5 grams of
quick-acting carbohydrates. The recommended dose of 3
tablets begins to work in about 10 minutes.
“I used to drink Mountain Dew when I had problems,”
says Kristina, “ but glucose pills are easier to carry
with me and they don’t have caffeine.”
Becton-Dickinson® glucose pills and Insta-glucose™ gels
were developed for diabetics, but similar fast-acting
carbohydrate gels have been developed for athletes under
names like Gu, PowerGel, Clif Shot, Rocket Pocket and
Squeezy.
Gels are generally faster-acting than sports bars because
they contain no fat or fiber. However, some gels may have
added caffeine. Read the labels! |
