THE STUDIES ON AEROBIC WORK CAPACITIES OF PREPARATORY SCHOOL CHILDREN (I) / 体力科学

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<BR>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.<BR>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.<BR>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.<BR>4) Correlation coefficients between body weights and absolute values of maximal oxygen uptakes were .8986 for males and .5626 for females.<BR>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.
