Feasibility Study Of Incremental Squatting On College Students' Cardiorespiratory Endurance

Purpose:cardiopulmonary endurance can be measured directly or indirectly.Direct measurements are the most accurate,but specific and heavy instruments are needed;the existing indirect tests cannot be completed by one person and they also require physiological indicators,there are also requirements for the site size of these tests.The purpose of this study was to design a method to predict college students' maximal oxygen uptake by the incremental squatting test,and to verify the validity of it.College students' maximal oxygen uptake can be measured with no specific instrument on the premise of that method is feasible.This will lay the foundation for national fitness and personal lifelong sports.Subjects and methods:120 volunteers were recruited from the Shandong Normal University via flyers and phones,and one hundred and one subjects(50 were males and 51 were females)were included in;subjects performed incremental squatting test and YMCA test randomly;to analyze the differences in form index and sports index between men and women;to analyze the correlation between relative V02max and other indicators.Results:eighty-eight subjects completed both incremental squatting test and YMCA test;there was significant difference in form index between male and female;the difference in sports index between male and female was not significant;the correlations between the squatting times and the relative V02max in male,female and the total are significant(r=0.613,p<0.01;r=0.488,p<0.01;r=0.537,p<0.01).Conclusion:it is feasible to evaluate the cardiopulmonary function by incremental squat test.
