Abstract:
According to the past results of Sports Test, it was found that the night part-time high school students showed the significantly lower performance in endurance run than the full-time high school students. This fact may be partly due to the fatigue and the lack of motives necessarily caused by their mental and physical works in day time. This study was attempted to determine their aerobic work capacities (PWC170, Vo2max) in the same experimental condition as used for the full-time high school students and simulteneously comparing them with those of the full-time high school students in the same district. The subjects were 59 male and 38 female, aged from 15 to 19 years.
The results obtained in this study were as follows
1) The mean values of PWC170 (kpm/min) for boys increased slightly with increasing ages till 18 years. But girls showed almost same values through the ages. The maximal value were 910kpm/min at the age of 18 years for the boys and 617kpm/min for the girls aged 16 years respectively.
2) For boys the mean values of PWC170 (kpm/kg/min) ranged from 14 to 15kpm/ kg/min and ranged from 10 to 11kpm/kg/min for girls.
3) As for the mean values of Vo2max (l/min) of the boys increased slightly untill the age of 18 years. But girls were same in values through all the ages. The maximal values were 2.71/min at the 18 years for boys and 1.81/min for girls aged 15 years respectively.
4) For boys the mean values of Vo2max (ml/kg/min) decreased slightly from 49.48 ml/kg/min with ages. The mean values of Vo2 max (ml/kg/min) ranged from 34 to 35 ml/kg/min for girls.
5) The night part-time high school students were lower than the full-time high school students in PWC170 (kpm/min), PWC170 (kpm/kg/min), Vo2max (l/min) and Vo2max (ml/kg/min) for boys. For girls no significant differences were in these valiables after the age of 16 years.
