Relationship between physical activity and the amount of maximal oxygen uptake of the freshmen of a university: Comparing students of college of physical education and general college

ABSTRACT

BACKGROUND: Thesedays, the physical strength of adolescents had been weakened compared to the past. The reasons are that adolescents like to enjoy watching TV or video and PC in their rooms and going to school by car even though it is near distance. Therefore, the authors were to investigate the relationship between their physical activity and the amount of maximal oxygen uptake. METHODS: The subjects of this study were 103 freshmen of the college of physical education and 115 freshmen of general college of a university. The instruments used in this study are the step-test and the questionnaire which is composed of sex, age, physical activity, inactivity, rate of perceived exertion, and sports activity. RESULTS: The quantity of the physical activity of the freshmen of the college of physical education such as daily walking distance, floors of step-up and active sorts was significantly higher than that of the freshmen of general college. The hors spent on sitting in chair is less than that of freshmen of general college. The quantity of physical inactivity such as watching TV or video and using PC of freshmen of the college of physical education was lower than that of freshmen of general college. The amount of maximal oxygen uptake(VO2max) estimated by the step-test was significantly higher in freshmen of the college of physical education than those of general college. CONCLUSION: The amount of maximal oxygen uptake of the freshmen of the college of physical education was higher than that of freshmen of general college. And VO2mas was related with physical activity, sports activity and RPE.
