Abstract

The purpose of this study was to determine the riding on the bicycle or cycling in children from viewpoint of physiological aspect. In this experiment, at first, using a special electric device, maximal and ordinary cycling speedswere measured. Forty children, aged 5 years, of male and female, were employedas subject. The maximum and ordinary cycling speeds were 3.40 m/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 purpose of this study to determine the oxygen intake and cardiac 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 0.391/min-0.481/min, respectively. It could be said that the physiologicalintensity of cycling is insufficient to improve the aerobic working capacity of children. Making comparison of the oxygen intake and heart rate between theflat lane and upward slope, those for upward slope were much more than for theflat lane. Verf.-Referat (gekuerzt)
