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 1413 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
