Abstract:
Maximal oxygen uptakes of 85 preparatory school children (46 for males and 39 for females), aged 5 and 6 years, were determined by means of ground run. Their motor performances such as 25 meter dash run, 50 meter dash run, standing broad jump, 5 minute endurance run and muscle strengths of grip and back were also measured. The following results were obtained:
1) Mean values of maximal oxygen uptakes in terms of body weights were 49.46ml/ kg/min for males and 46.30ml/kg/min for females and the significant difference was found between the sexes.
2) Correlation coefficients between the first and second measurements in the 5 minute endurance run were .9044 for males and .7757 for females, and therefore the reproducibi-lity was higher for males than for females.
3) Correlation coefficients between maximal oxygen uptakes in terms of body weights and the performances of 5 minute endurance run were .4170 for males and .0486 for females.
4) Correlation coefficients between body weights and absolute values of maximal oxygen uptakes were .8986 for males and .5626 for females.
5) Regression equations of absolute values of maximal oxygen uptakes (1/min) to body weights (kg) were y=.051x-.025 for males and y =.024x+.408 for females.
