Type and dose of daily energy expenditure (DEE) play a major role in modulations of health status and an increased knowledge of these dimensions of physical activity in congestive heart failure (CHF) patients would be valuable for clinical and epidemiological aims. We propose a new self‐administered DEE questionnaire adapted to CHF patients and tested its validity. One hundred and five stable CHF participants, NYHA class I–IV, LVEF=33.2±6.1% performed an incremental symptom‐limited V o 2 (peak) test and filled in the questionnaire for DEE calculation. Reproducibility ( n =24), sensitivity ( n =21) of the questionnaire and inter‐observer variability ( n =105) were tested. Intensity levels were identified from DEE and their relationships to V o 2 (peak), ventilatory and anthropometric characteristics were assessed by simple and multiple regression models. Reproducibility and sensitivity were high ( r =0.98 and 0.88, respectively, P <0.0001) and inter‐observer error reached 1.37%. DEE was highly correlated to physical activity energy expenditure ( r =0.96, P <0.0001). Relationships between DEE, V o 2 (peak), V E / V o 2 and anthropometric characteristics were significant. An activity level above 3 MET was the best intensity criteria related to V o 2 (peak) ( r =0.62, P <0.0001) and DEE ( r =0.80, P <0.0001). The questionnaire seems reproducible, sensible and valid for DEE estimation. V o 2 (peak) appears related to DEE and especially to activities above 3 MET in CHF.
