Abstract
The present study is to analyze as the wave motion derived from the function for the annual change of physique and motor fitness of preschool children (four, five - year - old girls) by applying the fourth degree polynomial to annual between 1969 and 1999. For tens of certain kindergartens in the Aichi prefecture, height and weight(as physique), and 20m dash, standing long jump, tennis-ball throwing, jumping one leg and chinning exercises(as motor fitness) of four and five-year-old preschool children in 1969, 1979, 1989, 1999 were obtained as statistics. Analysis of variance was carried out to these statistics between annual (from 1969 to 1999). Polynomial set up annual as horizontal axis was applied to significant statistics as result of analysis of variance. Regarding the physique, it shows the trend of increase according to annual change (between 1969 and 1999). Regarding the motor fitness, 20m dash and standing long jump show the trend of increase, however, tennis-ball throwing show a decreasing trend according to annual change, especially in tennis-ball throwing, it is shown that shift to a slow trend of increase about from 1980 to 1995.
