Students Time Vital Capacity And Maximal Oxygen Uptake Of The Status Quo Analysis And Correlation Study

Maximum O2 Uptake (VO_2max) is one of the main indicators of the maximalaerobic exercise capacity for human body. The measurement of VO_2max has animportant role in evaluating the growth and development levels, the potentialcardiopulmonary function, and athletic performances for young students. Vitalcapacity and Timed Vital capacity of the lungs are the physiological indicatorsreflecting ventilation ability and dynamic process of the lungs. But there are very fewcresearch data of VO_2max together with vital capacity and timed vital capacity,especially the literature reports about relationship research between those indicators.This study takes 210 college students (138 students of Physical Education Majorand 72 students of Nonphysical Education Major) as subjects, and measures theirVO_2max, vital capacity, timed vital capacity, index vital capacity/body weight, bodymass index (BMI) and instant heart rates of different phases. The purpose of this studyis to discover and analyze the current fitness state of students, especially the potentialability of cardiopulmonary function and aerobic work capacity, and to explore therelationship between VO_2max and vital capacity, and timed vital capacity.The research methods of this study include literature documentary method,experimental methods, statistical methods and comparative methods. The evaluationmethod of 1600m slow run on the fields, computerized IC card stair method are usedfor measurement of VO_2max, and the Chest Microspiro HI-501 made in Japan is usedto measure the vital capacity, timed vital capacity.The study results show: (1) The measurement results of VO_2max by usingevaluation method of 1600m slow run on the fields are basically consistent with thatby the computerized IC card stair method, therefore under certain conditions theformer one can replace the latter one, and safer and easier, and can be popularized insome extant (2) The rest and instant heart rates during exercise for boy students ofphysical education major (PEM) are lower than that for boy student of nonphysicaleducation major (NPEM) (p<0.01),but no significant difference for girl students in...
