Strong Muscles, Strong Bones

Exercise in any form - mild, moderate
or intense - is good for you and can help
reduce the risk of disease and keep the
heart healthy.

But when it comes to strengthening bones,
milder forms of activity may not be enough.

Thirty-eight men and 46 women, ages 55 to
75 years, all of whom were generally healthy
but didnít exercise regularly, were recruited
to help determine the link between physical
activity and bone strength.

Researchers concluded that neither overall aerobic fitness nor mild
physical activity had a significant effect on bone density. Greater
muscle strength, however, was associated with stronger bones.

''Although some activity may be better than none at all for certain
aspects of health, like heart health, milder forms of activity may not
be sufficient to hold off or attenuate the age-related decline in bone,
'' says lead researcher Dr. Kerry J. Stewart of Johns Hopkins University
School of Medicine in Baltimore, Maryland.
