One third to one fourth of main life is devoted to growth and motor development. An urbanization and a lack of big muscular activity in childhood may lead to impaire development of individual physical activity and attendant function. A riding on a bicycle is the play which is so great favorite with the children. The purpose of this study was to determine the riding on the bicycle or cycling in children from view point of physiological aspect. In this experiment, at first, using a special electric device maximum and ordinary cycling speeds were measured. Forty children, aged 5 years of old of male and female, were employed as subject. The maximum and ordinary cycling speeds were 3.40m/sec-4.45m/sec and 1.30m/sec-1.65m/sec for male, 2.94m/sec-3.68m/sec and 1.20m/sec-1.52m/sec for female, respectively. There was a difference in the cycling speed among the size and type of bicycle, sexuality, and physical fitness level of subject. It is the further the purpose of this study to determine the oxygen intake and cardio response of the schoolboys and schoolgirls, aged 6-9 years old, during cycling with various speeds at different lanes. During cycling at flat lane heart rate and estimated oxygen intake were 113 beats/min-128 beats/min and 0.39 l/min-0.48 l/min, respectively. It could be said that the physiological intensity of cycling is insufficient to improve the aerobic working capacity of children. Making comparison of the oxygen intake and heart rate between the flat lane and upward slope, those for upward slope were much more than for the flat lane.
