abstract="Bone density was studied in intercollegiate athletes and older athletic women. Single-photon densitometry was used to assess bone density parameters at a new distal radial site, the midradius, and the first metatarsus. Dual-photon densitometry assessed bone density of the lumbar spine. Eleven intercollegiate tennis players, 23 swimmers, and 86 older &quot;athletic&quot; women from 23 to 75 years of age were compared with age-matched nonathletic controls. &quot;Athletic&quot; describes adult women who exercised at least three times per week, 8 or more months of the year, for a minimum of 3 years. The radius and metatarsus bone content of intercollegiate athletes was significantly above control values. Lumbar spine density was significantly higher only in tennis players. Mean bone density values for adult &quot;athletic&quot; women were also significantly greater than in age-matched controls. In the oldest athletic group (55-75 years of age) bone measurement values in radius and lumbar spine were in the same range as for younger &quot;athletic&quot; women. In contrast, after 50 years of age, these values in the control population decreased by 0.7%/year. Therefore the largest variance (increase) from age-matched controls occurred in the oldest &quot;athletic&quot; group. Also, we have established a distal radial density value (using our modified site) below which we consider women &quot;at risk&quot; and recommend further bone health evaluation. Only two adult athletic women greater than 55 years of age fell into this category. It is concluded from this cross-sectional study that a regularly maintained athletic program for adult women may reduce the rate of &quot;normal&quot; bone mass loss accompanying age, particularly postmenopausally.(ABSTRACT TRUNCATED AT 250 WORDS)<p /><p>Language: en</p>",
