PERBANDINGAN VALIDITAS TES VO2MAX ANTARA METODE MAKSIMAL DAN SUB-MAKSIMAL PADA REMAJA

Abstract

Direct measurement of VO2max is very costly in analyzing gas, so that indirect measurements or predictions with maximum and sub-maximal methods can be used as an alternative to measure VO2max ". Validity of the test VO2max, both the maximal and sub-maximal methods have already been calculated but separately in different populations. This study aims to compare the validity of the test VO2max the maximum and sub-maximal methods using the same subject with almost the same time. The validity used in this study is concurrent validity with Astrand Treadmill Test as a comparison test. 40 male students (mean age 19.2 ± 0.6 years; mean body weight 68.3 ± 5.2 kg) from the Department of Physical and Health Education at the State University of Malang volunteered to participate. The average test result "VO2max entered good criteria (45.2-50.9 ml. Kg-1. Min-1) and excellent (51.0-55.9 ml. Kg-1. min-1). The validity of MFT (0.88; p value = 0.037), Balke Test (0.90; p value = 0.003), Cooper Test (0.91; p value = 0.001) which represents the test VO2max with maximum method. Test validity VO2max sub-max method is represented by Queens test of 0.77 with p value = 0.067 and Rockport test of 0.75 with p value = 0.071. The validity of the test VO2max the maximum method is better at predicting the magnitude of VO2max than the submaximal method.
