An experiment was carried with 15 males (60.2 years old on the average) and 12 females (43.3 years old on the average) who had made it a rule to run regularly for exercise in daily life. The females were before the climacteric stage. Its purpose was to study the serum cholesterol fraction in relation to food intake and distance, duration, and speed of running for exercise.
The following results were obtained.
1) The composite variable of serum lipid synthesis tended to be affected more distinctly by the group with food intake as indicator than by the group with locomotion as indicator. It seemed to be influenced primarily by the amount of food intake to a remarkable extent, and secondarily by the group with locomotion as indicator. In this group an increase in consumption of energy with the practice of running exercises participated in bringing about such influence.
2) It was suggested that great care should be taken for food intake in performing running exercises as a habit, taking energy consumed by running into consideration.

The actual measurement of the body surface area generally take much trouble. And the existance of some interrelation among the height, weight and the others now lead to the calculation of the body surface area using a way of multipling these factors by a constant coefficient. After much investigation about a variety of calculation formula which have desingned by now we reached a conculusion that a from A=K₁X+K₂Y+Q (Howland-Dana from) is more desirable than the others, above all by applying X for the height (Hcm) and Y for the weight (Wg) the most desirable approximation can be got. From this point of view we achieved a new calculation formula for Japanease adult man and woman as follows. A=0.0901W+62.49H+266 for man and A=0.1309W+ 37.33H + 1799 for woman come as the result.
