FLORINDO, Alex Antonio and LATORRE, Maria do Rosario Dias de Oliveira. Validation and reliability of the Baecke questionnaire for the evaluation of habitual physical activity in adult men. Rev Bras Med Esporte [online]. 2003, vol.9, n.3, pp.129-135. ISSN 1517-8692. http://dx.doi.org/10.1590/S1517-86922003000300002.
The aim of this study was to verify validity and reliability of the scores for physical exercise in leisure (PEL), leisure and locomotion activities (LLA), and total score (TS) of the Baecke habitual physical activity questionnaire in adult males. Twenty-one students of Physical Education were evaluated. For validation, the maximum oxygen uptake (O2max) and the decrease of the heart rate in percentile (%DHR) were measured through the Cooper's 12-minute walk or run test, and an annual index of physical exercise (IPE), and a week index of locomotion activities (ILA). The reliability was verified through test-retest with interval of 45 days. The Pearson correlation coefficient, and partial correlation adjusted for age and body mass index were used for validation. The intraclass correlation and paired t-test were used for reliability. The results indicated that %DHR was correlated with LLA and TS (r = 0.47 and p = 0.030; r = 0.48 and p = 0.027, respectively). IPE was correlated with PEL and TS (r = 0.56 and p = 0.008; r = 0.46 and p = 0.036, respectively). ILA was correlated with LLA and TS (r = 0.64 and p = 0.002 and r = 0.51 and p = 0.017, respectively). There was no significant difference in PEL, LLA and TS means in test-retest. The intraclass correlations were r = 0.69; r = 0.80 and r = 0.77, respectively for PEL, LLA and TS. In conclusion, the Baecke questionnaire is valid and reliable to measure habitual physical activity in Brazilian adult men.
