Daily physical activity levels with objective measures of physiological variables can be of great help for evaluating the physical independence of patients. Exercise energy expenditure (EEE) and resting energy expenditure (REE) can provide indications of total energy expenditure representing functional body responses in daily activity. The aim of the present study was to examine those physiological values among different health conditions. Data triangulation was used: subjects were 31 healthy elderly in Study 1 (aged 74.1±
6.0 years), 8 male patients with gastrectomy in Study 2 (62.0±
9.4), and 12 female patients with ischemic cardiac disease in Study 3 (66.3±
6.5). EEE was measured using a microelectronic pedometer, and REE was measured using a portable calorimeter. Studies 2 and 3 conducted measurements at multiple time points until the patient reached a stable condition after discharge from hospital. In Study 1, EEE and REE were 3.83±
1.49 kcal/kg/day and 25.0±
4.3 kcal/kg/day, respectively. In Study 2, EEE and REE were 2.10±
0.80 and 23.5±
2.4 at 1 month after discharge and 2.80±
1.20 and 24.0±
2.5 at 3 months (ns), while in Study 3 EEE and REE were 1.35±
0.72 and 19.0±
4.7 at 1 month; 1.23±
0.82 and 17.1±
4.7 at 3 months; and 1.73±
0.53 and 20.5±
4.0 at 12 months (ns), respectively. EEE and REE in Studies 2 and 3 were lower than those of the general population of the same age. Our findings suggest that the healthy elderly maintained walking-based activity, while patients conserved their energy in such activity, and that this was reflected in EEE and REE. Thus, reduced EEE and REE appear to reflect health conditions during adaptation to normal daily life, and the physiological value of these variables can be identified.
