Although National surveys conducted by Ministry of Education, Culture, Sports, Science and Technology indicated severe decrease of physical fitness and motor abilities on children and youth, the declined phenomena were not identified on four categorized groups in the number of days of daily exercise and sports activities. Severe decrease is due to replacement of number of each group. The most remarkable replacement of cross sectional analysis on 10 years old female was recognized between “almost every day” and “sometime”. Whereas category “almost every day” moved down from first in 1989 to second place in 1990, category “sometime” moved up second in 1989 to first place in 1990. The purpose of this investigation was to identify specificity of each polygonal line of 4 group ratio by cross-sectional and semi-longitudinal cohort analyses from 1977 to 2015 of National surveys. (1) Whereas the critical point of inversion revealed on female by cross-sectional data has remarkable ripple effect, this phenomenon was not identified on male polygonal lines. (2) After three polygonal lines on low rankdesigned convergence of each sex in 1999, bipolarization of the number of days of daily exercise and sports activities extends. (3) Two trends of mid-1990's identified on cross-sectional and semi-longitudinal cohort analyses must be elaborated.
