PURPOSE: To determine the effects of progressive resistance training on mobility, muscle strength, and quality of life in nursing-home residents with impaired mobility.
METHODS: Nursing-home residents aged 77 years and older with impaired mobility were recruited in Berlin, Germany. The eight-week exercise program consisted of progressive resistance training twice a week. Mobility (primary outcome) was assessed with the Elderly Mobility Scale (zero = worst, 20 = best) at baseline and after 8 weeks. Muscle strength (secondary outcome) was determined by the eight-repetition maximum. The Short Form-36 Health Survey was used to assess quality of life.
RESULTS: Of the 15 participants (mean age 84 years, range 77-97 years), ten completed the 8-week program. Mobility (Elderly Mobility Scale mean ± standard deviation pre 14.1 ± 3.2 and post 17.5 ± 3.6; P = 0.005) as well as muscle strength of upper and lower limbs improved (from 62% at chest press up to 108% at leg extension machine), whereas most quality of life subscales did not show considerable change.
CONCLUSION: Resistance training twice a week over 2 months seemed to considerably improve mobility and muscle strength in persons aged 77-97 years with impaired mobility.
