摘要：本研究の目的は, 1956〜60年, 1964〜68年と, 1971〜74年に実施した測定結果に基づいて, 10才〜14才までの日本人児童の形態的発育と機能的発達を分析し, 形態的発育における促進現象の考察と, 機能的発達における都市と農村の年代差を明らかにすること, さらに, 形態的発育と機能的発達との関連について相対成長の立場から考察することである. 対象は縦断的に測定された都市児童の男子316人, 女子283人, 農村児童の男子110人, 女子84人である. 測定種目は身長, 体重, 握力, 立幅とび, 立位体前屈, サイドステップ, 肺活星である. 結果を要約すると次のとおりである. 1. 近年における日本人児童男女の形態的発育は顕著で, 大型化の傾向が続いている. 2. 男子の身長における年間発育量のピークは1964〜68年と1971〜74年の都市, 農村ともに11〜12才で同時期に出現している. 3. サイドステッフ゜, 肺活量, 握力の発達傾向は地域や性によって違いがみられたが, 都市, 農村の男女とも近年の児童がすぐれていた. 4. 身長〜握力について, アンバランスな発達は身長152cm以後の問題として捉えることができる. 身長, 立幅とびについて, 近年の児童がより遅く変移し, 大型化により増大した体重を移動させるだけの筋力やパワーが, 形態的発育に比例して増大していない. 身長〜肺活量について, 年代的な差異はほとんどない.
其他摘要：The purpose of this study was to analyze the peculiarities of morphological growths and functional developments of Japanese children form 1O to 14 years old; to observe the phenomenon of so-called "ascelalation" in growth; and to clarify the age difference between the urban and the rural children in functional developments; and to clarify the relationship between morphological growths and functional developments by the relative growth on the investigation which was performed in the 1956〜60, 1964〜68, and l971〜74. The materials used for this study were the longitudinal data of the height, weight, grip strength, standing-long-jump, standing-trunk-flexion, side-step and vital capacity of 316 boys and 283 girls in urban areas, 110 boys and 84 girls in rural areas. The results obtained were as follows; 1. Larger growth of Japanese children, boys and girls, were significantly evident in recent years, and the tendency toward larger growth is still going on. 2. The peak of increments in height from year to year in boys, both in urban and in rural areas, in 1964〜68 and 1971〜74 appeared in the same age (11〜12 years old). 3. There existed some differences in children's development of side-step, vital-capacity, and grip-strength according to area and sex. However, modern children, both in urban and in rural cities, showed superiority to those in the older period. 4. An unbalanced development in height vs. grip-strength relationship was observed after children reached to the height of 152 centimeters. The critical point on standing-long-jump vs. height curves appeared more lately among recent children. Therefore, the muscular-strength to carry the larger body-weight was supposed not grow in proportion to morphological growth. There was almost no age difference concerning vital capacity vs. height.
