Back strength of children in elementary school were measured by the "rope"aftached to the back strength dynamometer deviced by the author. The correlation between the back strength and physique was studied. The results were obtained here as folIows: 1) Correlations between the back strength, measured by the rope attached to the back dynamometer, and physique are rather weak than previous findings in 10years boys. It was revealed that the correlation between the back strength & physique was lower in girls than in boys. 2) It was found that there is definite correlation between the back strength and other muscle strength in both sex as shown in the last paper. 3) It was revealed that there is no significant difference between boys and girls, in the grip strength, while there is a significant difference between them in the back strength as well as in the arm strength.
