摘要：Ernesto C, Silva FM, Pereira LA, Melo GF. Cross Validation of Different Equations to Predict Aerobic Fitness by the Shuttle Run 20 Meters Test in Brazilian Students. JEPonline 2015;18(1):46-55. Indirect cardiorespiratory fitness (CF) tests have been proposed as a feasible alternative to predicting aerobic fitness. Regardless of feasible use of Shuttle Run 20 meters test (SR20m Test) in Brazilian schools, to date no study has investigated the validity of the main equations in predicting the VO2 max by SR20m in Brazilian schoolchildren. Ninety Brazilian students 13 to 17 yrs of age (38% male, 62% female) participated in this study. All subjects performed an Incremental Treadmill Test with gas analysis (TT) to determine VO2 max and the SR20m Test on different days. VO2 max obtained from the TT was compared to the VO2 max predicted by SR20m using 3 different equations (Léger, Kuipers, and Barnett). The findings indicate that for the males only, the equation by Léger was different compared to TT (P=0.023) with a strong correlation between TT and all the equations (Léger = 0.76; Kuipers = 0.75; Barnett = 0.76). For the females, only the equation proposed by Léger did not differ from VO2 max obtained TT (P=0.181). Moderate correlations were observed for Léger, Kuipers, and Barnett (0.53; 0.54; 0.66, respectively). Therefore, we recommend the use of Kuipers and Barnett equations for males and Léger’s equation for females to predict VO2 max in Brazilian school children.
