The purpose of this study is to answer the question whether delivering newspapers is effective to the maintenance of fitness or not. Subjects were five males, 22 to 61 years of age, and three females, 19 to 48 years of age, who delivered newspapers by bicycle for 60 to 80 minutes a day, five or six days per week throughout the year.
Each subject performed graded exercise by bicycle ergometer (Monark) in a laboratory to determine mine maximum oxygen uptake and to obtain a regression equation between the heart rate and VO₂. Then, the heart rates of daytime were recorded in snowy (February or March) and non-snowy (April) seasons.
Seven of the eight subjects satisfied the required level of maximum oxygen uptake for health maintenance which was recommended by Japanese Ministry of Welfare. Mean value of the heart rate during the newspapers delivery in snowy season was significantly higher than that of non-snowy season (112.5±4.2 vs. 105.9±4.3beats·min^-1). From a regression equation of heart rate and VO₂ in each subject, the exercise intensity during the task were estimated as 21.2±1.7 and 19.0±1.8ml·kg·min^-1 (6.1±0.5 and 5.4±0.5 METs), or 50±10 and 45±11 %VO_2max in snowy and non-snowy seasons, respectively. Therefore, it was concluded that the delivering newspapers, particularly in snowy season, was effective to the maintenance of fitness.

The purpose of this study is to investigate the relationship between the beginning period of walking alone and the beginning period of fundamental movements. The subjects are 1, 252 children aged from 2 to 6 years. The fundamental movement items in the questionnaire consist of 24 types of movements. The results are as follows;
If the beginning period of walking alone is early, the beginning period of fundamental movement is early as well. It was considered that the positive relationship also was found in beginning period between walking alone and 15 types of fundamental movements. Fifteen types of fundamental movements which indicated the positive relationship were as follows; climbing down, passing through, hiding oneself, running, climbing up, hanging down, jumping from a height, body rolling, walking on a balance beam, leaping, climbing up a tree, inverted supporting, kicking, catching, throwing. Their beginning periods were earlier among fundamental movements' ones.

In order to study the relationship between lifestyle and mental health, students were questioned on some items of lifestyle and KMI (Kyudai Medical Index) three times before and after the matriculation and 75 samples of male students were obtained. The results were as follows:
1. Their lifestyle before the matriculation were the most regular one, next to campus life or the spring vacation one.
2. The scores of division B and items of B1-B9 of KMI as an index of mental health degree showed that the satisfactory mental health of students comes during the spring vacation, at the ordinary campus life and at the time preparing for the matriculation, in order.
3. Their lifestyle and mental health were correlated to the same factors such as the time they could have and the school and family interference with their life, but in different ways.

In this paper, the relationship between dental functions (biting force/biting pressure) and physical fitness, motor ability and physique among 16 female junior high school students was examined. Some relationship was found between biting force or biting pressure and certain measurements of physical fitness, motor ability, or physique, above all, between the biting pressure and situps.
