男子の体重,胸囲におけるMPV年齢別平均発育速度曲線の解析

Abstract

The effectuality of a Wavelet Interpolation Method (W I M) for local approximation was proposed by author's previous paper. In this paper, it is to analyze and describe mean growth velocity curve classified by M P V age of that by the W I M to examine the characteristics of weight and chest girth growth velocity curve. The growth distance curve is interpolated to longitudinal weight and chest girth growth distance data(6 to 17 years of age), and is differentiated as the growth velocity curve. M P V age is determined from the growth velocity curve, and the statistic of the M P V age is used to describe the mean growth velocity curve in weight and chest girth. As a result, five groups in the mean growth velocity curve classified by M P V age was set up as maturity types (early, somewhat early, average, somewhat late and late maturity type), and both phenomena of mid-growth spurt and after-growth spurt was shown in almost maturity types. This tendency in weight and chest girth was a little different from the case of height.
