This study was intended to investigate on annual differences of height growth pattern. Twelve years (ages from 6 to 17 years) of two longitudinal datas of standing height been situated annual differences of five years, one was O group that was data from 1967 to 1978 years of A institute of technology students (71 boys), another was N group that was data form 1972 to 1983 years of certain high school students (231 boys). Distances and velocities in both O and N groups were calculated and described their curves, and peak height velocity ages (P. H. V. ages) were judged from velocity curves. Both of them were grouped according to their P. H. V. ages into each 5 groups. Distribution of groups classified by P. H. V. ages and characteristics of distance and velocity curves were investigated to make a comparison between O and N groups, and as for changes of growth amount during the adolescent growth spurt. The results were summarized as follow. Distribution of appearance for groups classified by P. H. V. ages were not changed too both O and N groups. As for characteristics of distance curves, tall boys before adolescent were attained to adolescent growth spurt period more earlier than short ones, and final height was showed a tendency that premature boys were shorter than average and late mature ones. Premature boys were showed a tendency to be large in change of growth amount durig adolescent growth spurt, as for characteristics of velocity curves. The above characteristics of distance and velocity curves were not changed too both O and N groups.
