Doesn't everybody wish that they
had access to a personal coach for their questions about training and fitness?
Road Bike Action recently caught up with Johnathan Edwards M.D. Dr. Edwards
is a practicing sports doctor and anesthesiologist in Las Vegas, Nevada. He has been
a sports doctor for American cyclists as well as in Europe. He also worked with
athletes during the Paris Dakar rally. As a former professional motocross racer and
current Cat 2 road racer, he understands the health and training needs of
cyclists of all levels.
I
am a Cat 3 level racer and should I stretch my hamstring and
quadriceps muscles before my criteriums?
Contrary
to past thinking, stretching those hamstrings and quads without
warming up may be more detrimental to muscular strength that
previously thought. The latest research shows that stretching a cold
muscle can decrease muscular strength up to 30-percent.
Since
you were a little tyke in grade school, the PE coach has taught you
to stretch before you engage in physical activity. This dogma has
been ingrained in our brains and we continue on as adults. Research
has shown that those long held beliefs can cost you 30 percent of
your strength. The old presumption that performing a stretch for 20
seconds, (i.e. - static stretching) is actually bad for you. In a
recent published study conducted at the University of Nevada , Las
Vegas , the athletes generated less force from their leg muscles
after static stretching than they did after not stretching at all.
Furthermore, other studies have shown that this type of stretching
decreases muscle strength up to 30 percent.
So
what does this have to do with cyclists? Stretching muscles is common
before a criterium or a time trial. Before a long road race, this is
probably not an issue unless you are trying to go for a break right
away. Given this info, the best way to warm up is to just ride the
bike. A warm up should loosen muscles and tendons increasing the
range of motion of various joints. What is important is to increase
blood flow to all parts of the muscles. And this also lends some
evidence to applying liquids and gels that cause local heat and
vasodilatation of the skin, this may help as well; wearing leg
warmers may help. One medical journal study showed that the
quadriceps muscle tissue of rabbits could be stretched farther before
tearing if it had been warmed up. Furthermore, a study
published earlier this year showed that knee injuries were decreased
by about 50% in female soccer players who followed a warm-up program
that included dynamic warm up exercises.
While
static stretching is still commonly practiced, it doesn’t
improve the muscles ability to perform with more power. You may feel
as if you’re able to stretch farther after holding a stretch
for 30 seconds. But you have increased only your mental tolerance for
the discomfort of the stretch; the muscle is actually weaker. Thus,
spin away!
If you have your
own question about health or training that you would like to ask a
coach please send them to fitness@roadbikeaction.
