description <p>Abstract</p> <p>Background</p> <p>Consistently swelling proportion of the frail elderly within a modern society challenges the overstrained public health sector to provide both adequate medical care and comprehensive assistance in their multiple functional deficits of daily living.

Ninety-one frail elderly (F 71 M 20; mean age 79 years) were recruited from both nursing home residents and community dwellers and randomly split into four groups: Group I – progressive resistance exercises (PRE) + functionally-oriented exercises (FOE) + nutritional supplementation (NS), Group II – PRE + FOE + placebo, Group III – standard exercises (SE) + FOE + NS, Group IV – SE + FOE + placebo. Each group pursued a 45 min. exercise session 5 times weekly.
