保育所の幼児689名を対象に身体意識の発達と保育者のかかわりについて追究した。その結果, 以下のことが明らかになった。
1. 体の事実に関する知識の発達を検討するために, 身体部位と動作語認知の調査を実施した。どの部位も個人差が大きく, 特に動作語の腕を振るは6歳後半男児でも18.8%しか認知していなかった。
2. 体のイメージ形成の発達を検討するために身体画を採用した。身体画の描画面積は身体画Aより身体画Bの方が大きかったが有意な差ではなかった。
3. 姿勢や運動のために必要な骨格や筋肉を自動的に調整する能力の発達を検討した。ラテラリティ, 正中線交叉, 片足立ちに個人差がみられた。

Recently, it is feared that the fitness for protection of the younger generation in Japan will fall down. The purpose of this study was to clarify the blood pressure regulation by utilizing a regulating reflex method of blood pressure among younger generation in Japan.
The study was made on 430 students, the 7th to the 9th grade at junior high school in Tokyo, from February to June 1995.
The results were summarized as follows:
1) The ratio of poor function in blood pressure regulation increased in comparison with the result of the investigations carried out in 1956 and 1984.
2) The blood pressure partly didn't drop just after the changing position from the lying to the sitting posture. The blood pressure didn't recover up to the resting value, even if 180 seconds passed after changing posture. A predominance of sympathetic nervous system was suggested.
3) It is necessary to reexamine the traditional criterion of regulating reflex method of blood pressure.

The purpose of this study was to investigate the life styles and physical activities of senior high school and technical college students in a snowy region both in snowfall and non-snowfall season. Questionnaires on the life style and physical activity were sent to 1675 students in Hokkaido.
The following results were obtained.
1) The students went to bed and got up earlier during snowfall season than during non-snowfall season. However, the hours of sleep were almost the same in both seasons.
2) More than a half of the students attend to school in snowfall season by different way from non-snowfall season. The commuting time in snowfall season was much longer than that in non-snowfall season.
3) More than one-third of the students answered that the amount of their physical activities decreased during the snowfall season. This trend was more noticeable among students who exercised 3 or more times a week than among students who exercised less than 3 times a week.
4) For students who did not participate in sports club activities, the shoveling snow in winter was found to be effective to compensate for hypokinetic sensation exercise.
5) In snowfall season, students tend to exercise for prolonged time with low frequency and low intensity, however in non-snowfall season they tend to exercise for shorter time with high frequency and high intensity.

The growth in the height of children in Japan was compared with that in Switzerland. After World War II, Japanese improved physically.
The growth in the height of Japanese children who were born between 1954 and 1956 shows a similar tendency to that of children in Switzerland during the same time, but the change in the height of Japanese children was comparatively less: 5.9cm to 8.9cm in boys and 5.3cm to 8.5cm in girls than that of Swiss children.
During the next 20 years, Japanese children became taller and close to the height of Swiss children. For example, the height of the 12 to 14 year old boys and the 11 to 12 year old girls in Japan became nearly equal to those of Swiss children.
It is said that the primary factors promoting the growth of children are changes in food, clothing and house. After World War II, nutrition and the living environment improved as the Japanese economy developed. The diet changed from rice and pickles to a more balanced diet. The 11 year old boys and 13 year old girls, grew remarkably. It is probably because primary school meals were planned nutritionally. When the students entered high school, their diet returned to unbalanced one and they were subjected to a stress for preparing examination. As a result, the rate of growth in height decreased rapidly.
