| Résumé : | [BDSP. Notice produite par INIST 0R0xRIe0. Diffusion soumise à autorisation]. Objectives. This study determined the effect of enriched foods and all-around physical exercise on bone and body composition in frail elderly persons. Methods. A 17 week randomized, controlled intervention trial, following a 2x2 factorial design- (1) enriched foods (2), exercise, (3), both, or (4) neither-was performed in 143 frail elderly persons (aged 78,6 5.6 years). Foods were enriched with multiple micronutrients ; exercises focused on skill training, including strength, endurance, coordination, and flexibility, Main outcome parameters were bone and body composition. Results. Exercise preserved lean mass (mean difference between exercisers and nonexercisers : 0.5 kg 1.2 kg ; P<. 02). Groups receiving enriched food had slightly increased bone mineral density (+0.4%), bone mass (+0.6%), and bone calcium (+0.6%) compared with groups receiving nonenriched foods, in whom small decreases of 0.1%, 0.2%, and 0.4%, respectively, were found. These groups differed in bone mineral density (0.006 0.020 g/cm, P. 08), total bone mass (19 g ; P=04) and bone calcim (8 21 g ; P=03) Conclusion. Foods containing a physiologic dose of micronutrients slightly increased bone density, mass, and calcium, whereas moderately intense exercise preserved lean body mass in frail elderly persons. |
