Vigorous Exercise
Linked to Longer Life, New Study Says
Summary
There has been a common debate on how much
vigorous activity humans should participate in. The studies that were conducted
generated different results. Some of these studies suggested that we should engage
in vigorous exercise consistently to prevent chronic diseases and early
mortality. Other studies stated that adequate exercise is just as good.
Presently, a large new study in JAMA
Internal Medicine proposes that vigorous exercise can reduce early
mortality significantly, regardless of body weight or chronic disease status.
This study was administered by researchers
from James Cook University and the University of Sydney. Together, they observed
data that tracked over 204,000 participants, forty-five years old and older,
for a span of six and a half years. These participants were distributed into
three groups; those who engaged in only moderate activity versus those who partook
in vigorous activity thirty percent of the time, or more than thirty percent.
Examples of moderate exercises or activities include swimming for leisure,
social tennis, or household chores, whereas jogging, aerobics, or competitive
tennis would be labeled vigorous activity.
The results from this study indicated that
people who participated in vigorous exercise up to thirty percent of the time
had a nine percent reduced risk of dying, while the people who engaged in
vigorous exercise for more than thirty percent of the time reduced their
mortality risk by thirteen percent.
Analysis
One of the researchers stated that whether
a person is obese, have a heart disease, or diabetes, he or she will have a
greater chance at longevity with some amount of vigorous activity. I find this
to be true because a couple of years ago, one of my family members was obese
and pre-diabetic. After changing her diet, and exercising regularly, she lost
80lbs and was no longer developing diabetes 2.
All in all, exercise of any kind and amount can produce a significant difference
in someone’s life if it is done consistently.
