Free-living TEE and PAEE were estimated with the DAQIHF (TEEquest), motion sensor (Armband\u00ae TEEActi) and measured over 2 weeks using DLW (TEEDLW). Resting metabolic rate (RMR) and body composition were assessed with different methods, and peak V\u0307O2 with quality of life were correlated to TEE. Bland\u2013Altman and Student\u2019s t-test analyses were used to compare methods. Statistical significance was set for P &amp;lt; 0.05. Mean TEE did not significantly differ between TEEDLW and TEEquest (+352.4 kJ.24h\u22121; +5.3%; P &amp; NS) for the whole group, nor between women or men, NYHA class, or cardiomyopathy: dilated cardiomyopathy\/ischaemic cardiomyopathy. Bland\u2013Altman plots revealed no systematic bias for TEE between methods. In a subgroup of women, TEEquest was significantly higher than TEEacti (P &amp;lt; 0.05). RMR estimated from bioelectric impedance overestimated measured RMR (16.4%, P &amp; 0.0028). Patients spent 9.4% of their TEE in activities \u22653 metabolic equivalents. Measured peak V\u0307O2 and estimated from the questionnaire were similar (14.1 \u00b1 4.7 vs. 14.8 \u00b1 3.4\u2005mL.min\u22121.kg\u22121; P &amp;lt; 0.0001) and were correlated to both TEEDLW and
