Study: Exercise May Prevent Parkinson's By Kathleen Fackelmann, USA Today Men
who engaged in regular, vigorous exercise as teens and young adults
drastically cut their risk of developing Parkinson's disease later in life, a
study reports Tuesday. As many as 1 million people in the USA, including actor
Michael J. Fox, have this progressive neurological disease, which commonly
strikes after age \(50 .\)
In addition to suggesting that exercise could ward off the disease, the
findings also raise the hope that physical activity might help hold the line
on brain cell destruction in people who already have it.Robin Elliott,
executive director of the Parkinson's Disease Foundation in New York, said the
study is promising because there is no cure for Parkinson's. Doctors today
have no way to stop or delay the progression of the disease, which affects the
brain region that controls movement. Common symptoms of Parkinson's are
tremors and a shuffling gait. Researcher Alberto Ascherio of the Harvard
School of Public Health and his colleagues studied 48,000 men and 77,000 women
who were relatively healthy and middle-aged or older at the study's start.
Over the course of the study, 387 people developed the disease. The team did a
statistical analysis to look for a link between physical activity and the risk
of Parkinson's. Men who said they jogged, played basketball or participated in
some other vigorous activity at least twice a week in high school, college and
up to age 40 had a \(60 \%\) reduced risk of getting Parkinson's, says the
study, which was published today in Neurology. The team found no such
protection for women. But the women in this study came of age in the '50s and
'60s, an era when young women did not have as many opportunities to
participate in sports. Ascherio says. The study had so few female athletes
that any protection may have been missed, he says. This study's findings are
supported by animal research: Michael Zigmond, a researcher at the University
of Pittsburgh and his colleagues have reported that exercise protects rats
from developing a Parkinson's-like disease. No one knows for certain whether
exercise can prevent or delay the symptoms of Parkinson's in humans. But there
is plenty of evidence suggesting that a regular fitness regimen might ward off
a host of ailments as diverse as heart disease and Alzheimer's. That leads
experts such as Zigmond to recommend a vigorous workout on most days of the
week. "We know that exercise is good for you in ways that go beyond any one
condition."
