RESUMO
PURPOSE: This study aimed to develop a prediction model for peak oxygen uptake ((Equation is included in full-text article.)O2peak) in children with spina bifida (SB), considering peak workload (Wpeak), peak heart rate, age, sex, anthropometric measures, walking level, physical activity level, and level of the lesion. METHODS: Data of 26 participants with SB performing a graded arm crank test were used to develop the prediction model. An unrelated data set of participants with SB was used for validation. RESULTS: The following equation was developed to predict (Equation is included in full-text article.)O2peak of participants with SB: (Equation is included in full-text article.)O2peak (mL/min) = 194+18 × Wpeak - 110 × sex (adjusted R(2) = 0.933, SEE = 96 mL/min). Bland-Altman analysis showed a nonsignificant mean difference between the measured and predicted values of (Equation is included in full-text article.)O2peak (-0.09 L/min) and limits of agreement of -0.4036 and 0.2236 L/min. CONCLUSIONS: The prediction model shows promising results; however, further validation using the same protocol is warranted before implementation in clinical practice.
