In order to study the physical fitness of rural children in Gifu prefecture, a total of 128 rural boys and girls aged 8-14 years old in the Tokuyama-Elementary School and-Middle School, which are in a far rural district from busy civilized urban distriet, were measured for the developmental status, i. e. physique, examination of physical fitness, maximum working capacity, cardiorespiratory function and urinary excretion in summer, 1962, and the comparison was made on the results obtained there with those of the average Japanese children of the same age. The results obtained were as follows: 1) Little or no difference was found between physical development of rural children and that of average Japanese boys and girls; i. e. the physique of rural children was not superior nor inferior to the value of the average Japanese children. 2) The record of sprint games, such as 50m-sprint-run, broad jumping, ball throwing, Sargent-jump, grip strength and back strength of rural children was lower than that of the Japanese average. Whereas, the endurance ability measured with a long-distance running (1500m for boys and 1000m for girls) was tended to be higher in the rural children, especially in the girls, than the average Japanese value. However, no significant difference was presented in the flexibility test(forward bending of the upper-body in standing posture) between rural and average Japanese values. 3) The examination of cardiopulmonary function : i.e. E.C.G., blood pressure, heart rate, vital capacity and maximum expiratony flow rate exhibited no abnormal sign. The systolic and diastolic blood pressure tended to increase with age, but the heart rate tended to decrease. The examination of the urinary glucose, protein and occult-blood remained normal, and most of the urine pH of the girls were within the range between 6 and 7, whereas, those of boys were between 5 and 6. 4) The maximum working capacity (maximum oxygen intake, vital capacity) showed a linear increase proportional to age and physique (body height, body weignt, body surface, etc,) over the range of the age tested. Sexual difference appeared after 12 years of age. 5) The possibility was suggested that the maximum O_2 intake could be predicted from the vital capacity of the same individual regardless of age, sex and physique, and a theoretical background for that was discussed.
