RESUMEN
PURPOSE: To compare functional fitness (FF) levels among independent-living (IL) and day care (DC) elderly women of different age groups and to analyze changes in FF after 8 months of participation in an exercise program intervention for the IL elderly women. MATERIALS AND METHODS: A total of 674 elderly women were divided into four IL groups with age in the range of 60-64 years (IL60-64, n=149), 65-69 years (IL65-69, n=138), 70-74 years (IL70-74, n=135), and 75-79 years (IL75-79, n=83), and four DC groups with age in the range of 60-64 years (DC60-64, n=35), 65-69 years (DC65-69, n=34), 70-74 years (DC70-74, n=47), and 75-79 years (DC75-79, n=53). The intervention consisted of a multimodal exercise training, 3 days per week for 8 months. Senior Fitness Test battery performances were obtained at baseline and after 8-month intervention. RESULTS: Significant differences were identified between all IL groups and DC groups in all FF tests (P<0.001), except between IL70-74 and DC70-74 in the chair sit-and-reach. Analysis of covariance (ANCOVA) identified significant improvements in all FF tests between pre- and posttests in the IL groups (P<0.001), except in the chair sit-and-reach for the IL70-74. ANCOVA also showed a significant declining performance in all FF tests for DC groups (P<0.001), except in the chair sit-and-reach for the DC70-74 and DC75-79. CONCLUSION: IL women are more fit than institutionalized DC elderly women. The multimodal training was effective in improving all FF components related to daily living activities, in all age groups. In contrast, institutionalized elderly showed a clear tendency to worsen their FF over the time.
