概要 The purpose of this study was to investigate the physical characteristics and maximal aerobic power (MAP) of the Thakali tribe, which lives in the mountainous area of the Mustang district, in the West...ern region of Nepal. A total of 222 males and 209 females, aged from 20 to 80, participated in this study. The measurements of their physique were carried out for body height, body weight and skinfold thickness (triceps, subscapular, suprailiac, umbilical and calf). The percentage of body fat(%Fat) was calculated by the equation of Nagamine using the skinfold thickness, body weight and body surface area. MAP was estimated by Margaria's indirect method. No age-group difference in the mean body height(male; 159.9±6. 0-163.4±7.3cm, female; 150.8±5.5-153.1±5.2cm) was found in this group, and these values were similar to those for other groups in the mountain areas of Nepal. The mean body weight, skinfold thickness, %Fat and the appearance rate of obesity in the male middle-aged groups were significantly larger than those of the younger groups. Although the energy intake per day in this group was lower than that for other rural groups in Nepal, the %Fat and the appearance rate of obesity in the middle-aged were higher than those of the rural groups and were similar to those of the sedentary group in Nepal. In females, no significant differences in the mean body weight, skinfold thickness, (%h~at or the appearance rate of obesity were found between the Thakali tribe and other groups of mountain villagers, but the rates were higher than in other rural groups in Nepal. The mean MAPS of the Thakali males were almost at the same levels as those of the rural group of the Nepal in all age groups, but those in the younger female group were lower than those of the rural groups. It is thus considered that the fatty body composition in the aged male group and lower physical fitness in the younger female group may be due to their physically inactive lifestyle, professions as hotel owner, shopkeeper or shop assistant, etc.
ネパール上国のWesten Region, Mustang DistrictのTukucheおよびMurpha村を中心とする20歳以上のタカリ族の男性222名,女性209名の形態および推定最大酸素摂取量(MAP)を調査した。これらの調査値を1981年の同地区の調査値および他の地区住民の調査値と比較して検討した。1)身長は男女とも世代差が認められず,1981年の調査値とも差が認められなかった。約10年間の間に住民の社会経済的変化は起こっているであろうが,その変化は,身長に影響を与えるほど大きな変化ではないと考えられた。そしてタカリ族の身長は,チベット系住民やシェルパ族とも差がないと思われる。2)体重,皮下脂肪厚,体脂肪率および肥満者の出現率は,1981年に比べ多くなっていた。また男性では,若年に比べて中高年者が大きい傾向にあった。そしてこれらの値は,男性ではチベット難民キャンプの住民と,女性ではネパール北東部のシェルパ族とほぼ同様であった。摂取エネルギーは必ずしも多くないにも関わらず,体重や体脂肪などは自給自足的な丘陵地農民や都市近郊農民より大きかった。3)男性のMAPは必ずしも低くなく,シェルパ族や丘陵地農民と大差が認められなかった。女性では世代間のMAPの差は大きくなく,それは20歳代の低体力化の影響によると考えられた。20歳代の値は,座業的なチベット難民キャンプの20歳代や日本人と大差が認められず,他のネパール集団のそれより低かった。
