Abstract
Extract: Most investigators studying changes in body composition during growth agree to the desirability of having longitudinal data. A group of 110 boys and 126 girls, studied annually for 4-5 years with 880 measurements of total body K in a 2π liquid scintillation whole body counter, had total body K vs. height and total body K vs. weight data that fit previously described regression lines.
Speculation: Given an adequate diet and environment, children increase their total body K in a predictable amount in reference to skeletal growth.
