摘要：This study aimed to create an equation to predict peak oxygen uptake from data of the 6-minute walk/run test and demographic and anthropometric variables in adolescents. The results of the 6-minute walk/run (6WRT); peak oxygen uptake; height; body weight and body mass index (BMI) in 125 adolescents age 10 to 14; of which 66 were female; were assessed. They were divided into a validation and a cross-validation group. A linear regression analysis was conducted to assess the associations between the independent variables 6WRT; age; gender; anthropometric measurements and the dependent variable peak oxygen uptake in the validation group. The Bland-Altman method was used to test agreement between measured and estimated values. It was found that the best model to predict peak oxygen uptake included the 6-minute walk/run test; BMI; and gender. These variables presented a multiple correlation coefficient of 0.77 and a standard error of estimate of 3.99 [(mL/kg)/min]. The accuracy of the model was tested by applying the equation created in the validation group to the cross-validation group and total sample. The Bland-Altman method results did not indicate any systematic bias or heteroscedasticity in both the validation and cross-validation groups. In conclusion; our multiple regression equation [peak oxygen uptake = 41.946 0.022(6WRT) – 0.875(BMI) 2.107(gender)] is adequate for predicting peak oxygen uptake in adolescents age 10 to 14.
