aintenance and the improvement of strength in elderly persons lead to improved everyday functioning by these persons (Pollock, Graves, Swart, and Lowenthal, 1994, pp. S88-S95). Frequency, intensity, and duration are critical considerations in the design of a physical exercise program for persons 65 years old and older. In comparison with physical exercise programs for younger adults, the frequency and duration of physical exercise should be longer, while the intensity of such exercise should be lower (Pollock, Graves, Swart, and Lowenthal, 1994, pp. S88-S95). Resistance exercise training has been found to be generally safe and effective for improving muscle strength in persons aged 65 years old and older (Graves, Pollock, and Carroll, 1994, pp. S17-S22). The magnitude of such improvement that may be expected depends upon training intensity and the initial fitness level.
