Weight loss is not the only benefit people gain from exercising.
Researchers found that men who exercised regularly and vigorously
early in their adult life lowered their risk for developing Parkinson's
disease when compared to men who did not.
What is Parkinson's disease? It is a progressive nervous system
disease that usually occurs after age 50. It destroys brain cells
that produce dopamine (a brain chemical) and is characterized by:
- Rigidity
- Muscular tremor
- Postural instability
- Slowing of movement
Uncovering the Parkinson's-Exercise
Link
To determine the relationship between physical activity and Parkinson's
disease, researchers involved more than 48,000 men and 77,000 women--who
were free of Parkinson's disease, cancer or stroke--in a study.
Participants completed comprehensive questionnaires on disease,
lifestyle practices and physical and leisure time activities (beginning
in 1986 and updated every two years through 2000). Throughout the
study, a total of 387 cases of Parkinson's disease were diagnosed--252
men and 135 women.
The study showed:
-
The most physically active men at the start of the study lowered
their risk of developing Parkinson's disease by half, compared
to men who were least physically active
-
Men who reported engaging in regular physical activity in early
adult life lowered the risk for Parkinson's by 60 percent,
compared to men who did not
-
Women in the study who participated in strenuous activity in
the early adult years were also associated with a lowered risk
of Parkinson's (yet this link was not statistically significant
and there was not clear relationship between physical activity
later in life and Parkinson's risk)
