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<. groups receiving enriched food had slightly increased bone mineral density mass and calcium compared with nonenriched foods in whom small decreases of respectively were found. these differed g p. total p="04)" calcim conclusion. containing a physiologic dose micronutrients whereas moderately intense exercise preserved lean body frail elderly persons.>
