Abstract

体育大学女性スポーツ選手19名(平均年齢19.8±1.0歳)と一般女性10名(平均年齢22.5±2.1歳)の全員に対しDXAによる骨塩量測定を施行した.さらに骨代謝に関連する血液検査を,同意を得た上記選手19名中17名に行い,以下の結論を得た.(1)一般女性群と比較して,陸上長距離選手群では除脂肪体重が高く体脂肪率が低い傾向が,柔道群では体脂肪率が低く腰椎・脛骨骨密度が高い傾向が,それぞれ統計学的に有意に認められた.(2)水泳群では一般女性群に比し,脛骨骨密度が低い所見が有意に観察された.(3)17名の選手群の内65%が血中カルシトニンの低下を,47%がエストラジオール[E<SUB>2</SUB>]低下をそれぞれ示したが,選手E 2低下群に骨塩量が不足している所見は,今回の調査では認められなかった.

Dual energy X-ray bone absorptiometry (DXA) analysis and blood examination were carried out on college sports women (n=19, average 19.8±1.0 years) and general women (n=10, average 22.5±2.1 years). Several findings were obtained as follows. (1)Lean body mass was higher and % fat was lower significantly (p<0.001, p<0.01) in female long distance athletes compared with general women. (2) Bone mineral density on lumbar spine (L<SUB>2</SUB>-L<SUB>4</SUB>) and tibia shaft was higher significantly (p<0.05, p<0.05) in female Judo participants compared with general women. (3) Bone mineral density on tibia shaft was lower significantly (p<0.05) in female swimmers compared with general women. (4) Blood estradiol was low in 47% of the female college sports women. But they did not show the tendency towards lack of bone mineral content.
