From April in 1964 to March in 1965, I gave guidance in regular living and physical and health education under proper nutrition to the 26 children (21 boys, 5 girls) in acertain institution for so-called physically weak children and pupils in Gifu Prefecture, and tried to see its effect upon the restoration and increase of their health through the growth of form and fu nction. As the result of this investigation, the following conclusions were obtained. 1. The condition of nutrition. From the caloric point of view on the monthly condition of nutrition which is 2, 524.2 Cal (the rate of nutrition is 94.6%), with 81.6g in albumen and 5.06g in fat, they have the most calories in March (2, 446.3 Cal.) and the fewest in June (2, 270.2 Cal.). The rate of nutrition (supplied foods-remains of foods/supplied foods × 100) is the highest in March (96.3%) and the lowest in June (93.3%). Such being the case, measures must be taken to check the fall of nutrition in summer, and generally to increase the rate of nutrition. 2. The form. Seventeen boys were measured three times in a year (April, October, and March), in height, weight, girth of the chest, the index number of weight to height, girth of the chest to height, Vervaeck, Rohrer and Tsurumi-Nakatate, and it was found that height was below the national average. The rate of increase during a year is very remarkable in the index numbers of weight to height, Rohrer, and Tsurumi-Nakatate. Height and weight show an increasing tendency from April to October, while the others do from October to March. There is high correlation between form and nutrition (nutrition to height r=0.503, nutrition to weight r=0.552, nutrition to girth of chest r=0.609, nutrition to the index numbers of weight to height r=0.598, nutrition to the index numbers of girth of the chest to height r=0.392, nutrition to the index numbers of Vervaeck r=0.732), and significance is observed in height, weight, girth of the chest, the index numbers of weight to height, girth of the chest to height, and Vervaeck. 3. The function. Fifteen boys were measured three times in a year (April, October, and March) in 50-metre running, standing broad-jump, soft-ball throwing, Serjent jump, Berpeetest, strength of back and vital capacity, and it was found that they were generally below the national average. Esp ecially in 50-metre running, strength of grip, strength of back, and vital capacity, it was verb remarkable. The rate of increase during a year is remarkable in all the items, especially, in 50 metre running, Serjent jump, strength of grip and vital capacity. Individually, those who were inferior in April showed a considerable increase. As in from, the rate of increase from April to October being compared with that from October, to March, soft-ball throwing, strength of grip and strength of back show an increasing tendency from April to October, while the others do from October to March. There is high correlation between function and nutrition (nutrition to 50-metre running r=0.408, nutrition to standing broad-jump r=0.465, nutrition to soft-ball throwing r=0.549, nutrition to strength of grip r=0.529, nutrition to strength of back r=0.534), and significance is observed in 50-metre running, standing broad-jump, soft-ball throwing, strength of grip and strength of back. In view of the abovementioned results, I am convinced that those physically weak children who are apt to be regarded as dangerous and neglected will be able to recover their health under proper management and education.
