Abstract:
Maximal oxygen uptakes were determined by means of ground run for 53 male and 56 female subjects aged from 3 to 5 years.
Furthermore 38 male and 45 female subjects restricted on the age of 4 and 5 years were chosen and 5 minute run was loaded on them to know their aerobic motor performance.
The following results were obtained:
1) Male absolute values of maximal oxygen uptakes (l/min) avaraged 0.655, 0.789, and 0.904 respectively at the age of 3, 4, and 5 years. The corresponding values for females were 0.523, 0.751, and 0.808.
2) For males mean values of maximal oxygen uptakes in terms of body weight (ml/ kg/min) were 42.60, 47.36, and 51.31 respectively.
For females the corresponding values only reached 35.91, 44.48, and 44.20. The sex differences were found at the age of 3 and 5 years.
3) The developments of relative maximal oxygen uptakes (ml/kg/min) with increasing age (months) were expressed by the following regression equations for males and females respectively;
y=52.723 logx-44.071 (n=53, r=.487)
y=44.095 logx-33.980 (n=56, r = .445) .
4) The regression equations of absolute maximal oxygen uptakes (l/min) to body weights (kg) were the following ;
y=0.51x-.125 (n=53, r=.729) for males
y=0.043x+.007 (n=56, r=.747) for females.
5) During 5 minute run males could cover 798.85m and 844.00m respectively at the age of 4 and 5 years. The corresponding values by females were 779.29m and 785.38m. Males could run significantly faster than females.
6) The correlation coefficients between relative maximal oxygen uptakes (ml/kg/min) and distances covered for 5 minutes (m) were .500 for males and .510 for females respectively.
The regression equations of 5 minute run (m) and maximal oxygen uptakes related to body weight (ml/kg/min) were
y=5.034x+576.680 for mals
y=5.009x+558.408 for females.
