Sport and healthy way of life : run your way to health

When I started running seven years ago, I could manage only about a
quarter of a mile before I had to stop. Breathless and aching, I walked
the next quarter of a mile, then I jogged the next quarter of a mile,
alternating these two activities for a couple of miles. Within a few
weeks I could jog half way round Hampstead Heath without stop-ping. Soon
I started to run up the quarter-mile slope to the top of Parliament
Hill, although I had to stop at the top to get my breath back.
Eventually I found that I could even manage to get up the hill
comfortably. I started to run because I felt desperately unfit. But the
biggest pay-off for me was—and still is— the deep relaxation that I
achieve by taking exercise. It tires me out but I find that it does calm
me down. In those early days I saw few other runners. Now there are many
more—and not just the macho sports freaks. Men and women of all ages
have now taken up running. Some 25,000 runners aged five to 85 are
attracted each year to the Sunday Times Fun Run in Hyde Park. In the
last two years the London Marathon has become the biggest British
sporting event— overtaking the boat race and the Derby in the number of
spectators it attracts. When I started to jog I never dreamt of running
in a marathon, but in 1982 I realized that if I trained for it, it was
within my reach, and after a slow, six-month build-up I man-aged the
26.2 miles in just under four hours. A creditable performance for a
first-timer and a far cry from those days when I had to stop for breath
after a quarter of a mile. What about heart attacks?My story shows that
an unfit 39-year-old, as I was when I started running, who had taken no
serious exercise for 20 years, can do the marathon—and that this is a
sport in which women can beat men. But is it crazy to do it? Does it
make sense to run in the expectation of becoming healthier? What about
the chances of injuring yourself or dying of a heart attack? I was
personally convinced of the health benefits of running because I felt
unfit, and I wasn't worried about the risk of a heart attack, because I
was not a smoker and I was sticking to a fairly low animal-fat diet. But
one person I knew well did die immediately after a jog and plenty of
people told me I was mad to start running. Reassuring  evidence  now
comes from doctors in Seattle, showing that vigorous exercise actually
reduces the chances of heart attack. They found that people who had a
sudden heart attack when they appeared to be completely fit had taken
less exercise than those of similar age. According to their findings,
published in the Journal of the American Medical Association (volume
248, p 3113) it is necessary to take 20 minutes of vigorous exercise at
least two or three days a week to obtain some protection from heart
attack. Apart from jogging, the exercise might be swimming, singles
tennis or squash, digging or chopping wood. Whatever it is, the exercise
