Using The Drive Shot In Different Minutes To Measure The Students' Cardiopulmonary Function

Aims:The continuing descent of the level of students' cardiopulmonary function in China,is related to the low level of students' cardiopulmonary function;also,it is related to the detection index,the ways and methods of measuring,and the acceptability of the tests.At present,the index and method used to measure the cardiopulmonary function indirectly at home and abroad are not closely related to the exercise form,hobbies and the accustomed sport of the examinees.As a result,the examinees are tempted to arouse a feeling of contradiction,and they won't get full involvement in the tests.Furthermore,the muscle group involved in various sports events are different in strength level,and working conditions,and all the factors mentioned above will affect the results and assessment of the tests.This research is directed at the popular sport events in china in the research,we inquire into the cardiopulmonary function index and methods that are effective,easy to test and more acceptable to the university students with the aim to make the physical fitness monitoring perfect,promote the level of the students' cardiopulmonary function and provide a new aspect in cardiopulmonary function test.Methods:We choose randomly 30 undergraduates who are familiar with basketball playing from the Physical Education College of Hunan Normal University,and then we use the distance of drive shot in 6,9 and 12 minutes as the monitoring index.After that,we evaluate the effectiveness of the mark by measuring the maximal oxygen uptake directly.Meanwhile,we measure the exercise heart rate,the respiratory quotient and serum lactic after exercise and screen out an index which is valuable,acceptable and easy to measure.Results:The maximal oxygen uptake of the subjects is 43.74±6.18ml·kg^-1·min^-1,the heart rate at maximal oxygen uptake is 182.41±6.17times·min^-1,the respiratory quotient is 1.41,and the serum lactic is 92.36±12.47mg%,it indicates the results is valuable,reaches the test demand;the result of the subjects' 12,9 and 6 minutes drive shot is 2745.73±255.11m,2046.60±182.07m and 1502.33±88.84m,the heart rate after exercise is 183.46±7.33times·min^-1,186.42±8.15times·min^-1 and 189.06±7.91times·min^-1.The exercise time at the heart rate is more than 180times·min^-1,it is longer than 86%the whole exercist time,the 12, 9,6 minutes drive shot is highly-relevant to the test of the cardiopulmonary function.It shows the drive shot time higher than 6 minutes is an effective parameter of cardiopulmonary function to college students.And the questionnaire shows,all the subjects willing to choose the drive shot to test the cardiopulmonary function,it shows the exercise acceptable to the students.Conclusions:It is effective to use the drive shot in 12,9 and 6 minutes to measure the students' cardiopulmonary function,and the detection index is closely related to the exercise form,hobbies and the accustomed sport ot the examinees,so they are more acceptable.To mast the drive shot is not difficult,the examinees' technique has little influence on the test result,and the experiment devised in reason.
