Study On Female University Students Physical Monitoring Of Several Indicators Associated With Maximal Oxygen Consumption

Objective:Female college students by testing the basic physical condition, as well as the indirect determination of VO2max and direct determination of maximum oxygen uptake in both the direct assay of treadmill test results as the standard to compare the step test,800m run,12min run on the maximal oxygen uptake prediction."State Student Health Standard"in the physical representation of the science and research, for better monitoring of indicators for monitoring the physical fitness assessment of students screened indicators provide experimental basis for further improving the"National Student Health Standard "provide a reasonable theoretical basis.Methods:A random sampling method, from Changsha University, Changsha, insurance, schools, students in the school sample, the subjects were freshman girls, a total of80people. Using step test,800m run,12min run and other indirect VO2max test methods, and treadmill test results directly measured as the standard method, three kinds of indirect test methods are measured VO2max values were analyzed.Results:(1) Step test index was46.50±5.403,800m run of the test results for the242.03±15.823s.(2)12min run in the testing process, the subjects, the average heart rate over190times·min-1,12min and ran away from the1938.52±216.280 m, the inferred value of VO2max34.65±4.631ml·kg-1·min-1,12min after the test run, a large part of the subjects felt very tired or very tired.(3) Treadmill tests showed that the direct method, subjects the average maximum heart rate is196times·min-1, respiratory quotient above1.10, the measured VO2max value of32.62±3.106ml·kg-1·min-1(4) With the step test,800m run,12min run three kinds of indirect test methods with the measured VO2max treadmill VO2max direct method for the determination of statistical software used for processing, the results show that although the12min run inferred VO2max values than the measured value is high, but no significant difference (P>0.05), and12min run with the direct method treadmill VO2max measured the correlation coefficient of the highest,0.862(p<0.01). Step test index and treadmill VO2max values directly measured correlation coefficient0.263(P>0.05);800m treadmill running performance and the value of directly measured VO2max correlation coefficient-0.597(P<0.05).Conclusions:(1) Three kinds of indirect test VO2max treadmill test results and test methods for the direct correlation analysis, only12min to run with the direct method treadmill VO2max measured the correlation coefficient of the highest, and12min run with the measured results between the presumably non-statistically significant. Tips,12min run effectiveness, high accuracy, simple, is suitable for college students in China speculate indirect VO2max test methods. (2) Step test index and treadmill VO2max values directly measured correlation coefficient0.263, thus, indirectly, with the step test index of aerobic endurance assessment of our students is not appropriate.(3)800m treadmill running performance and the value of directly measured VO2max correlation coefficient-0.597,800m run prompted speculation China is not an ordinary college students are more suitable for the indirect VO2max test methods...
