摘要：正課体育の授業を体力増強の立場からとらえ, 運動量と質の問題をエネルギー消費の面から解明することを企図し, 運動の質をR.M.R., 量を運動量指数で表わすこととし,中学一年男子を対象として, 陸上, とび箱, バレーボール教材について測定した. 測定法は, 各授業をそれぞれ十数種の基本動作に分類し, 数名の被検者にダグラスバッグを着装させて, 基本動作の性質によって数分または数回実施させ, 単位時間あたりまたは一回あたりのR.M.R.を算出し, これを基にタイムスタディー法により授業のR.M.R.を算出した.従来のストップウオッチ法を改良し, テープレコーダーおよびビデオテープレコーダーを用いて分析の正確を期した. 結果は何れの授業においてもR.M.R.の平均は2〜3の範囲にあった. これは「ぶらぶら歩き」程度の弱い運動であり, また, 運動量指数からみた運動量の上からも不十分であり, 今後の授業計画は用具, 施設, 指導法などの改善が必要である.
其他摘要：The purpose of this study is to investigate the energy expenditure of the students during school hours of physical education in junior high school. From a course of study which was set by the Ministry of Education, truck and field, gymnastics and volleyball activities were taken up for measurment of energy expenditure. The activity time of each student in school hour was analyzed in seconds by the time study methods using tape-recorder and video-tape-recorder. The subjects were 117 healthy junior high school boys. The results were as follows; (1) In a course consisted of sprint and running broad jump, the mean R.M.R., Exercise Quantity Index (EQI) and Calorie Expenditure (CE) during 50 minutes were 2.19, 109.5, and 149.8 Kcal, respectively. The mean R.M.R., EQI and CE were 2.50, 125.0, 168.6 Kcal in the sprint event, 2.94, 148.6, 185.5 Kcal in the running broad jump event, 2.27,132.3, 158.1 Kcal in the vaulting box course, 2.35, 117.3, 166.2 Kcal in the volleyball event, respectively. (2) The R.M.R. of various activities obtained materials were as follows; 65.1 for 50m dash, 43.5 for running broad jump, 19.6 for vaulting box, 55.1 for spike action in volleyball, 41.9 for blocking in volleyball and 33.6 for volleyball rolling receive. (3) For each student, the actual exercise time length for given teaching material was rather short in one school hour of physical education. For example, the ratio of actual exercise time to one school hour was 7.4% in the sprint material, 8.2% in combination of sprint and running broad jump, 7.4% in the running broad jump, 10.5% in the vaulting box and 6.7% for the volleyball, respectively. In many cases, mote than 50% of one school hour was found to be occupied by sedentary activities. (4) The margin of error between the value of time study method and the observed value was not more than 1O%. (5) The results of this investigation show that the mean exercise intensity and actual exercise time with respect to R.M.R. and EQI in one school hour are insufficient to improve the physical fitness of junior high school students. Accordingly, instructional technique, educational equipment and facilities should be reexamined from a stage of planning for school physical education.
