摘要：中学生の優秀な中・長距離選手7を対象に, トレッドミル速度漸増負荷法(傾斜8.6%)によってVo_2max.を測定した. そのうち3名についてはexhaustion直後から40分間の酸素負債量を測定した. また中学放送陸上大会2,000m競走上位入賞者3名を対象に, レース・スピードに近い速度(300m/分)で2,000mを走行させ走行中の酸素摂取量を測定した. 以下はその結果である. (1) Vo_2max.の平均値は3.29l/分, また,体重当りの平均値は60.8ml/分であった. (2) V^^.o_2max.が得られた時の換気量の平均値は111.0l/分であった. (3) 2,000m走行中の酸素摂取水準は最後の4分間以上はVo_2max.の80%以上であった. (4) 酸素負債量はそれぞれ7.04l, 5.68l, 4.65lであった.
其他摘要：Metabolic responses during submaximum and maximum treadmill running were measured for seven excellent middle-long distance runners, aged 14 to 15 years. Oxygen intake, heart rates and respiratory rates were recorded during exercise and recovery phase. The maximum oxygen intake was measured by the speed progressive treadmill running test (8.6%slope). In the case of submaximum test, the subjects ran on the horizontal treadmill at a constant speed of 300m/min for 6'40". This speed was determined with their best records of 2000m running. The results obtained in this study were as follows: 1. The mean value of the maximum oxygen intake of seven subjects was 3.29l/min(2.49-3.631/min) and the mean value of the maximum oxygen intake per body weight was 60.8 ml/kg/min (57.2-69.0 ml/kg-min). This value is 30% more than that of Japanese ordinary adolescents of the same age, and it corresponds to 72% of Japanese top long-distance runners. 2. The mean value of the maximum ventilation was 111.0l/min (87.8-119.9l/min). When compared with college long-distance runners, these subjects demonstrated large ventilation relating to their maximum oxygen intake. 3. The mean values of oxygen pulse was 16.6ml/beat (12.8-17.9ml/beat) and tidal volume was 1.8l/freq. (1.4-2.2l/freq.) when maximum oxygen intake was obtained. 4. During 2000m treadmill running, oxygen was continuously consumed more than 80% of their maximum for the last four minutes. 5. The oxygen debt of the three subjects for the exhaustive exercise ware 7.04 l, 5.68l, and 4.65l, respectively.
