Abstract

Developmental patterns of several physical fitness elements in adolescent boys were investigated in reference with growth patterns of standing height. The data used consisted of 5 sets of the 7-year longitudinal data of 1969, 70, 71, 72 and 73 enrollments. The mean and standard deviation were determined in each elements with 5 sets of longitudinal data pooled. Then these statistics were used to determine the 10-steps growth and developmental channel for evaluating the individual growth and developmental status in each age. Then, all data were converted to the channel scores using these channels. Results were as follows; 1) By the channel method, growth patterns of standing height were classified into 3 patterns, i.e., early maturing, consistent and late maturing types. 2) Hierarchial cluster analysis was applied to the t-value matrix which was calculated between the patterns of 15 elements. For consistent type, 4 clusters were produced, while 5 clusters each were found for early maturing and late maturing types. 3) Developmental pattern curves of each cluster were drawn with the standard scores. With several exceptions, a certain increasing tendency could be observed in consistent and late maturing types. In the early maturing type, most of clusters showed the decreasing tendencies. 4) Between the groups with different growth pattern of standing height, the elements showing the same developmental pattern were not always same, and also each elements did not always show any identical pattern.
