SUMMARY
Energy requirements in active elderly individuals living in a rural region of Northwest Mexico
The energy requirements in free-living elderly rural people were investigated by measuring physical activity level and basal energy expenditure using a physical activity questionnaire and indirect calorimetry, respectively. Approximately 65 different occupational and leisure activities over the previous 12 months were considered. Energy expendilure by physical activity was estimated using PAL for specific activities reported in the literature. All 65 the activities were considered to adapt the questionnaire. Reproducibility was evaluated by administering the questionnaire on two separate occasions within 3- 4 week elapsed between them. It was found to be reliable for the study (Pearson correlation was r = 0.85; p<0.05). The physical activity level of the women and men were l.50±0.29 and l.65±0:66, respectively (p<0.05). The basal metabolic rate also differed between women and men (p<0.05) with 5348±7l9 kJ/day and 6l60±862 kJ/ day, respectively. Similarly the total energy expenditure was different (p<0.05) in women and men 83l1±l6l0 kJ/day and l02l0±2268 kJ/ day, respectively. Results indicate that the physica activity questionnaire presented can be an alternative methodology to estimate physical. activity in free-living elderly people and together with indirect calorimetry measurements can be useful to estimate their energy expenditure and hence energy requirements.
Keys words: Aging, basal metabolic rate, level physical activity, body composition, energy requirements.
