Abstract The purposes of the present study were to: (1) develop original equations to predict maximum voluntary ventilation (MVV) in African‐American adolescent girls; and (2) determine the validity of existing MVV prediction equations for use in African‐American subjects by comparing predicted MVV values in the literature with actual MVV values obtained in this study. Forced expiratory volume in 1 second (FEV 1 ), forced vital capacity (FVC), and 12 second MVV were measured with a clinical respirometer (Spirometrics model 2451) in 93 African‐American adolescent girls (13.5 ± 1.0 years). Age (r = 0.29). height (r = 0.38), FEV 1 (r = 0.52), and FVC (r = 0.48) were significantly ( P < 0.01) correlated with MVV. Multiple regression analysis was used to develop equations to predict MVV with age, height, and FEV 1 as predictor variables. Using Mallow's C p criterion, age‐FEV 1 and FEV 1 , equations appeared to be the most accurate predictors of MVV. When MVV was regressed on FEV 1 , in a no‐intercept model, the result was the commonly cited equation MVV = 35.0 × FEV 1 . Thus, the previously established relationship between FEV 1 and MVV can be extended to African‐American adolescent girls. Comparison of predicted MVV values calculated from other published equations with our subjects' actual values indicated that equations using age and/or height as predictors did not accurately predict MVV in our subjects.
