Title: Growth of the lean body mass during childhood and adolescence
Abstract: Determination of the K40 content of the human body in the whole body counter offers a means of estimating potassium content, and hence lean body mass. Fat content is obtained by subtraction. The lean body mass rises sharply during adolescence, particularly in the male in whom the maximal value (at 18 to 20 years of age) is 1.4 times that of the female where a maximum is attained by 15 or 16 years of age. Males have more lean body mass per unit height and less fat per unit weight than females. Average values for lean body mass in this study agree with those obtained by the other workers who have used total body water or densitometry.
