中国の大学生の身体活動に関するー考察 : 中国と日本の男子大学生の日常生活における身体活動量の相違について

抄録

The purpose of this study was to investigate physical activity levels of Chinese students in comparison with Japanese students. First, a questionnaire on exercise habits was distributed among the students of 4 universities in China and 6 national unversities in Japan. Answers were obtained from 1,262 Chinese students (771 males and 491 females) and 1,409 Japanese students (1,282 males and 127 females). Second, eighteen healthy male students (9 Chinese and 9 Japanese) who did not participate in athletic clubs were selected as subjects for the measurement of daily activity levels. The heart rate of the subjects were recorded daily during the daytime by using Heart Rate Memory (TKK Instrument Co.). Measurements were taken both in China and Japan to determine the heart rate levels of each subjects and these were compared to the %V^^.O_2 max of different workload levels determined by a Monark ergometer. The results are summarized as follows: 1. The Chinese students tended to engage in exercise more than Japanese students in that (1) fewer complained about lack of exercise, and (2) a higher percentage of the population exercised habitually. Nevertheless, they did not have sufficient oppotunities for sports activity judging from the facts that (1) they had shorter exercise period (2) a lower rate of the population participated in athletic clubs and (3) fewer had experiented sufficient amount of exercise. 2. Although, in general; the Chinese subjects revealed higher rates of activity level exceeding 7O %V^^.O_2 max than the Japanese subjects, the durations of their exercise periods did not allow them to attain an essential time to improve aerobic power, except for one subject; while none of the Japnnese subjects fulfilled these conditions.
