Regional and total body bone mineral density in elite collegiate male swimmers

摘要

Background. To examine the role of long-term swimming exer- cise n regional and total body bone mineral density (BMD) in men. Methods. Experimental design: Cross-sectional. Setting: Musculoskeletal research laboratory at a medical center. Participants: We compared elite collegiate swimmers (n=11) to Age-, weight-, and height-matched non-athletic controls (n=11). Measures: BMD (g/cm~2) of the lumbar spine (L_2-4), proximal Femur (femoral neck, trochanter, Word's triangle), total body And various subregions of the total body, as well as regional And total body fat and bone mineral-free lean mass (LM) was Assessed by dual-energy X-ray absorptiometry (DXA, Hologic QDR 1000/W).
