Methods: Eighteen elementary obese male students aged 11-12yrs were recruited in the study. Each participant firstly completed an incremental exercise test to evaluate the maximal oxygen consumption (VO2max), and following four cardiorespiratory field tests, including the 600-m and 800-m running, 9-minute run/walk test and 6-minute walk test. The time required or the distances finished in the tests were defined as cardiorespiratory performance. Collected data were analyzed by Pearson's product-moment correlation to verify the correlation between VO2max and each of the four field tests performance. Besides, the coefficient of determination (r2) derived from linear regression analysis was defined as validity. Results: 1) 600-meter running, 800-meter running, 9-minute running and 6-minute walk test were significantly correlated to VO2max respectively (r=-.78, r=-.78, r=.70, r=.60, p<.05). 2) The coefficient of determination (r2) were 0.60、0.61、0.49 and 0.36, while the standard error of estimates (SEE) were 3.34, 3.32, 3.78 and 4.27. Conclusion: All the four tests were effective in evaluating the cardiorespiratory fitness of elementary obese male students. In terms of physiological characteristics and time efficiency, the 600-meter running test was recommended for elementary obese male students.
