Adults gain
substantial health benefits from two and a half hours a week of moderate aerobic
physical activity, and children benefit from an hour or more of physical
activity a day, according to the new Physical Activity Guidelines for
Americans. The comprehensive set of recommendations for people of all ages and
physical conditions was released today by the U.S. Department of Health and
Human Services.
The
guidelines are designed so people can easily fit physical activity into their
daily plan and incorporate activities they enjoy.
Physical
activity benefits children and adolescents, young and middle-aged adults, older
adults, and those in every studied racial and ethnic group, the report said.
It’s
important for all Americans to be active, and the guidelines are a roadmap to
include physical activity in their daily routine,” HHS Secretary Mike Leavitt
said. “The evidence is clear -- regular physical activity over months and years
produces long-term health benefits and reduces the risk of many diseases. The
more physically active you are, the more health benefits you gain.”
Regular physical
activity reduces the risk in adults of early death; coronary heart disease,
stroke, high blood pressure, type 2 diabetes, colon and breast cancer, and
depression. It can improve thinking ability in older adults and the ability to
engage in activities needed for daily living. The recommended amount of
physical activity in children and adolescents improves cardiorespiratory and
muscular fitness as well as bone health, and contributes to favorable body
composition.
The Physical Activity Guidelines for Americans are the most comprehensive of their kind.
They are based on the first thorough review of scientific research about
physical activity and health in more than a decade. A 13-member advisory
committee appointed in April 2007 by Secretary Leavitt reviewed research and
produced an extensive report.
Key
guidelines by group are:
Children and Adolescents -- One hour or more of moderate
or vigorous aerobic physical activity a day, including vigorous intensity
physical activity at least three days a week. Examples of moderate intensity
aerobic activities include hiking, skateboarding, bicycle riding and brisk
walking. Vigorous intensity aerobic activities include bicycle riding, jumping
rope, running and sports such as soccer, basketball and ice or field hockey.
Children and adolescents should incorporate muscle-strengthening activities,
such as rope climbing, sit-ups, and tug-of war, three days a week.Bone-strengthening activities, such as
jumping rope, running and skipping, are recommended three days a week.
Adults -- Adults gain substantial
health benefits from two and one half hours a week of moderate intensity
aerobic physical activity, or one hour and 15 minutes of vigorous physical
activity. Walking briskly, water aerobics, ballroom dancing and general
gardening are examples of moderate intensity aerobic activities. Vigorous
intensity aerobic activities include racewalking, jogging or running, swimming
laps, jumping rope and hiking uphill or with a heavy backpack. Aerobic activity
should be performed in episodes of at least 10 minutes.For more extensive health benefits, adults
should increase their aerobic physical activity to five hours a week
moderate-intensity or two and one half hours a week of vigorous-intensity
aerobic physical activity. Adults should incorporate muscle strengthening
activities, such as weight training, push-ups, sit-ups and carrying heavy loads
or heavy gardening, at least two days a week.
Older adults -- Older adults should follow
the guidelines for other adults when it is within their physical capacity. If a
chronic condition prohibits their ability to follow those guidelines, they
should be as physically active as their abilities and conditions allow. If they
are at risk of falling, they should also do exercises that maintain or improve
balance.
Women during pregnancy-- Healthy women should get at least two and one half hours of
moderate-intensity aerobic activity a week during pregnancy and the time after
delivery, preferably spread through the week. Pregnant women who habitually
engage in vigorous aerobic activity or who are highly active can continue
during pregnancy and the time after delivery, provided they remain healthy and
discuss with their health care provider how and when activity should be
adjusted over time.
Adults
with disabilities -- Those who are able should get at least two and one
half hours of moderate aerobic activity a week, or one hour and 15 minutes of
vigorous aerobic activity a week. They should incorporate muscle-strengthening
activities involving all major muscle groups two or more days a week. When they
are not able to meet the guidelines, they should engage in regular physical
activity according to their abilities and should avoid inactivity.
People with chronic medical conditions -- Adults with chronic
conditions get important health benefits from regular physical activity. They
should do so with the guidance of a health care provider.
