With advancing age the risk of developing osteoporosis rises. This
risk may be increased by having lower than normal peak bone mass, and
subsequent greater than normal bone loss. The chances of this
happening can be lessened by doing exercises that involve weight
bearing. This is because when you do weight bearing exercises your
bones adapt to the impact exerted by this extra weight and the pull
of your muscles by building more cells, and thus become denser and
stronger. The type of exercises that are most beneficial vary
depending on age.
Children
For children, bone strengthening exercises can start before they can
even walk. Crawling and active play begin the gaining of muscle mass.
After they have learnt to walk unaided, activities such as climbing,
walking and running, and jumping all contribute to the development of
strong bones.
Teenagers
and Young Adults
As
children reach adolescence an active lifestyle is crucial to
increasing bone mass. It is around this age that the most can be done
to achieve a high peak bone mass in their early twenties. All sorts
of competitive sports, from soccer to tennis to martial arts are
beneficial, as are more individual exercises. Skipping, body weight
exercises and high-energy activities
such as aerobics and dance can strengthen muscles, while putting
weight on the bones, encouraging them to increase cell production. In
order to build up strong bones children should aim to undertake 60
minutes of exercise a day.
Adults
From your mid-thirties natural bone loss begins to occur. In order to
reduce the rate of this, muscle-strengthening activities should be
done at least twice a week. This can include doing some of the
activities that young adults do, but also less exercise-focussed
pursuits, such as brisk walking, stair climbing, carrying groceries,
gardening and moderate-resistance weightlifting. These activities are
less aimed at building bone mass as they are at maintaining muscle
strength. Adults need less frequent exercise than children, but
should aim to do at least 150 minutes of cardiovascular exercise a
week, on top of muscle-focussed exercises.
Elderly
For elder individuals, or those at high risk of osteoporosis and
fragile bones, it is advised to avoid particularly high impact
exercises. However, maintaining a healthy, active lifestyle is
beneficial. Going for a walk or doing necessary housework are both
good ways of keeping active throughout the day. Swimming can improve
stamina and joint flexibility in a low-weight environment, while tai
chi is recommended as it is low impact but can improve balance and
posture while strengthening muscles in the legs.
Until a bone is broken, there are no symptoms of osteoporosis. As the
likelihood of developing it increases as you age the best
preventative method is to build up strong bones at a young age and to
sustain beneficial exercises throughout life.
