Popis:	Methods used for estimating physical activity measurement are suitable exclusively for adults. They are difficult to apply for the aged. The objective of this study is to assess actual condition of the daily energy expenditure (EE) and daily activity factor (DAF:EE/ basal metabolic rate -1) of the aged using heart rate (HR). Subjects used were 42 aged people: 17 men and 25 women, 35 from nursing home and 7 from their home, aged from 70.0 to 88.4 years old. Basal metabolic rate (BMR) was measured actually and EE was estimated by HR- oxygen consumption (VO2) method based on the two experimental active and non-active conditions formulas, between HR and VO2. Results obtained are as follows: 1. Mean BMRs measured in men and women were 20.5 kcal/kg and 19.8 kcal/kg, respectively. Mean EEs were 1590 ± 272 kcal/d and 1360 ± 264 kcal/d and mean EEs adjusted for weight were 27.4 ± 5.0 kcal/kg and 27.1 ± 5.4 kcal/kg in men and women, respectively. 2. Mean DAFs estimating from BMR and EE were 0.32 ± 0.22 for men, 0.33 ± 0.23 for women and 0.33 ± 0.23 on average. 3. Significant correlation (p
