A new study
published by the National Institutes of Health pulls together a body of
previous studies and makes it clear that middle-age and older adults should
be doing anaerobic exercise - high-intensity intervals and sprints rather
than slow, low-intensity exercise like walking, says 50 year old fitness
book author Phil Campbell, M.S., M.A.
sprinting types of exercise--whether it's running, cycling, swimming,
cross country skiing-are shown by medical researchers to make the body
produce significant amounts anti-aging growth hormone," says Campbell,
author of a fitness book for middle-age adults, now in it's 2nd edition
(Ready, Set, GO! Synergy Fitness, Pristine Publishers, 384-pages, $19.95).
reported that several well-known entertainers take growth hormone (GH)
injections for its body fat cutting, muscle toning, youth rejuvenating
properties, but Campbell cautions that there can be serious side-effects
from GH injections. At age 50, Campbell prefers getting the benefits of
GH by running sprints and other types of high-intensity exercise.
hormone injections are given to children with clinical stature growth
problems to help them grow normally," explains Campbell, "however,
GH does not make adults grow taller."
adults, GH can reverse several measurable clinical factors of the middle-age
bulge--now named "the somatopause" by researchers. The middle-age
somatopause is signified by energy decline, weight-gain (around the middle,
and hips), loss of muscle, and wrinkled skin after the age of 30.
exercise should be a part of every fitness routine," says Campbell.
However, he cautions that physician clearance and a progressive build-up
of the high-intensity exercise is necessary to prevent injury.
Campbell cites 160 biomedical research studies in his book to make the case middle-age and older adults should be performing shorter, but more intense forms of exercise.
