Abstract

We evaluated the influence of a twice-weekly group exercise program on visceral fat area (VFA) and plasma adiponectin (APN) in the elderly. Thirty-three community-dwelling elderly (age : 72.4±6.9yrs) participated in a 12-week supervised, geriatric exercise training program (GET) followed by a 12-week unsupervised GET (u-GET), which included stretching, strengthening, and balance-training exercises. Participants were evaluated for physical fitness, blood glucose, HbAlc, triglyceride, cholesterol, insulin, and APN. VFA was measured by computed tomography. All measurements were taken before the GET (TR1), after 12-weeks of GET (TR2), and at the end of the u-GET (TR3). Twelve weeks of GET produced significant increases in physical function measures. Both walking speed and functional mobility values at TR3 were significantly higher than TRl values. A significant reduction in VFA was seen at TR3 in men. APN progressively elevated from TRl to TR3 in women. In the frail elderly, 12 weeks of GET effectively increased functional ability and APN. The beneficial effects on VFA and APN were sustained following the participation in the unsupervised setting, suggesting that the frail elderly should be encouraged to participate and maintain a resistance training routine to achieve preferable effects on both functional ability and cardiovascular risk factors.
