Construction Of Evaluation Index System Of Muscular Endurance For Middle And Old Aged With Physical Disability In Beiiing

Objective: Based on the theory and empirical study,the suitable evaluation index and the corresponding test methods for the muscular endurance of the disabled middle and old aged are selected,to construct index system to reflect the muscular endurance,and preliminarily explore the evaluation criteria of muscle endurance,so as to provide reference for future ralated research.Subjects and Methods:The subjects were the disabled adults in various areas of Beijing.The main tests were questionnaire survey and fitness test.The Scientific verificationprocessincludestheoretical screening,completetedtesting,test-retests,Index of discrimination analysis,back verifications,then Construct the evaluation system.tandardized test with a validated index to investigate status.The basic test results for general descriptive statistics,differences between age can be used independent sample T-test;The feasibility was completed by the formula of completion degree;Paired T test and the Pearson analysis was used to weigh the stability and correlation of the index,the coefficient of variation of the evaluation index of discrimination;The formulation of the reference standard was made by the method of deviation.Results:1.As a result of theory screening,the muscle endurance index for wheelchair disabled : 60 s fixed load elbow flexion,60 s single arm bench press,Load out;for stand class: 10 cm sit ups,45° supine lifting leg time,30 s supine lift leg(90°),40 s seat experiment,30 s continuous squatting.2.Second step of screening : 60 s fixed load elbow flexion(92%),60 S single arm bench press(88%),45° supine lifting leg time(86%),40 s seat experiment(91%).3.The third screening was the test-retest reliability,the selected index was 60 s fixed load elbow flexion(P=0.28 r=0.64),45° supine lifting leg time(P=0.85 r=0.83),40 s seat experiment(P=0.27 r=0.73).4.After the index discrimination analysis and regression test selected the suitable index for60 s fixed load elbow flexion,45° supine lifting leg time,40 s seat experiment.5.The results of back generation test showed 3 tests of endurance status in different gender and age groups.Use deviation method to establish 5 grade evaluation grade of muscular endurance in different gender and age groups.Conclusion: Established muscle endurance evaluation index system,index for: 60 s fixed load bearing elbow flexion for Wclass,45 degree supine lifting leg time,and 40 s seat experiment for S class.The reference standard of 5 levels was made through the method of deviation.
