Research And Application In The Measure Of Maximal Oxygen Uptake

This paper investigated the testing methods of maximal oxygen uptake on 296 undergraduates both male and female. The methods used include direct cycling and indirect steps. Compared these two methods' testing results, analyzed the relativity between maximal oxygen uptake and other physiology indexes and deduced maximal oxygen uptake calculate formula for male and female using multiple regression. The results showed that:1.There is no significant difference on VO₂max between students of physical education and non-physical education department. There is significant relativity among VO₂max and the student weight, height, high rate, exercise load, exercise duration time (P<0.0001) .2.Testing results of second-high steps and cycling both showed that there is no significant difference on VO₂max between students of physical education and non-physical education department. There is difference of heart rate from the cycling testing results; there is significant different of instant heart rate from the steps testing results. There is high relativity between weight and maximal oxygen uptake (r=0.742, r=0.609, P<0.0001); high and maximal oxygen uptake(r=0.621, P<0.0001).3.Through step experiment result of VO₂max automatic metrical instrument, it can be used indirectly to judging of the heart-lung condition, which is a convenient, safe and relatively current method. It will get to know the tested maximal oxygen uptake and instant heart rate immediately.4.Put direct testing result of VO₂max as dependent variable and put age, high, weight and instant heart rate of step experiment as independent variable, using prediction deduced VO₂max calculate formula for male and female. It can be used to testing undergraduates' oxygen uptake capacity.
