Here, in comparison with community-dwelling middle-aged and older men, we investigated the skeletal muscle mass and bone mineral density of a Japanese alpinist (Mr. A) who, at the age of 80 years, is to date the oldest person to have climbed to the summit of Mount Everest (8,848 m). Using dual X-ray absorptiometry, we determined the appendicular skeletal muscle mass index (SMI), total bone mineral density (tBMD), whole body fat-free mass index (FFMI) and fat mass index (FMI) of Mr. A (84.6 yr) and 209 community-dwelling middle-aged and older men (50-79 yr, mean age: 68.1 yr). The SMI, tBMD, FFMI and FMI were 8.79 kg/m2, 1.075 g/cm2, 22.3 kg/m2 and 9.8 kg/m2, respectively, in Mr. A and 7.46 ± 0.81 kg/m2, 1.020 ± 0.100 g/cm2, 18.1 ± 1.9 kg/m2 and 5.5 ± 1.7 kg/m2, respectively, in the community-dwelling middle-aged and older men. The values in Mr. A were higher than those in the community-dwelling middle-aged and older men, with z-scores for the SMI and tBMD of 1.63 and 0.55, respectively. Mr. A maintained a high skeletal muscle mass and bone mineral density even at the age of 84 years, which may have been attributable in part to his long-term training for mountain climbing.

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.
