Preventing
Sports injuries
Part three — Technique
By MORT MALKIN
Athletes who perform at a high competitive level
are at high risk of injury. The human body is only flesh and bone;
and overtraining is overtraining. As dually noted in part one of
this series, avoiding excesses of distance, intensity and frequency
(how far, how fast, how often) will reduce
the chances of injury.
Another way to lessen musculoskeletal risk is the
old reliable: gently, gently. You may object, “But I’m so competitive,
I go all out on every play. I don’t know how to play gently.” Performing
at your best can be done gently, nonetheless. Gentle is a matter
of: 1) fluid form and 2) coordination of effort by all the large
muscle groups so as not to place undue stress on one or two muscles.
Fluid form is a matter of technique. In runners,
ground contact must be light and stride progression smooth. Such
form prevents injury and improves running economy. Two examples
are illustrative. A local high school middle distance runner, Lani
(not her real name), is tall and strong with a long stride that
she used for powering through half-mile or mile races. She almost
always took first place in local competition, but rarely won in
regional meets. Her bounding form caused excessive forces to be
exerted on the ligaments and joints of the lower body. In her senior
year, Lani suffered a ligament tear that
took her out of competition for a few weeks. Technique work could
have created a smoother, lighter stride and prevented her injury.
At the same time the energy costs of running would have been reduced
and her performance level would have improved.
The second example is from the world stage of track
and field. Jim Ryan had held the U.S.
record for the mile run for many years. An era later, Steve Scott
was the premier American miler. Scott tried many times but failed
to break Ryan’s record. A group of sports medicine researchers,
who were doing a study of running economy, had data on Ryan’s efficiency
and were testing Scott. They found that Scott’s running efficiency
was a little lower than Ryan’s. Steve decided to work on mechanics.
The following year his running economy was measured again and had
improved beyond Ryan’s best. Later that year, Scott broke the American
record. Technique!
Fluid form is just as important in other sports.
Underlying Wayne Gretsky’s arsenal of
skills was his wondrous skating. In soccer, Franz Beckenbauer
was seamless in his movements and was the most elusive of all the
superstars of the Pele era. The greatest basketball players, from Dr. J to Michael
Jordan, have been smooth in their movements as well as accurate
in their shooting.
The second component of “gently” is having the
burden of power production shared among large muscle groups. For
example, a pitcher in baseball can throw by whipping his arm around.
Or, he can throw with his shoulder and his arm. Better yet, he can
add hip and leg power to upper body effort. Thus, the force behind
a 100-mph pitch is shared by several muscle groups and the risk
of injury is reduced. The same principle is applied to golf—in a
perfect drive, hip rotation initiates the swing. Golfers start by
facing sideways and finish facing forward. In boxing, too, arm power
is supplemented with shoulder and hip power. The classic picture
of Joe Louis knocking out an opponent with a right cross
shows his power coming from his hip and shoulder as much as from
his arm. Athletes in the weight events in track and field—i.e. javelin
or shot put—learn early that hip rotation leads the throw. In each
of these events the athlete finishes with the entire dominant side
of the body forward. All the muscles cooperate.
Technique offers a third prequisite
beyond preventing injury and improving performance. It raises the
bar for aerobic exercise. As noted above, technique enlists more
large muscle groups for the power of athletic movement. In doing
so, aerobic power is increased. The equation is simple: a greater
muscle mass produces a greater aerobic effect. Whether your reasons
for aerobic exercise are for raising fitness levels, reducing size/weight,
or improving health, technique will heighten the aerobic effect.
Athletes, coaches and health educators need to
focus on technique.
