Abstract
Objective: To examine the effects of a total body recumbent stepper exercise program on blood pressure, strength and walking speed in elderly, assisted-living residents.
Design: A non-experimental (longitudinal) pre-post-test descriptive design was used to determine changes in physical performance measures after 13 weeks of recumbent stepper exercising.
Setting: Morningside Assisted-Living Communities in Middle Tennessee.
Participants: Thirty-nine volunteer, assisted-living residents with mean age of 85.5 ± 6.6 years, height of 1.6 ± .1 m, and weight of 63.6 ± 9.6 kg.
Interventions: Recumbent Stepper exercise program. The residents were classified into two groups based on the total time of exercise logged over the test period. One group exercised less than an average of nine minutes per week while the other group averaged nine or more minutes of exercise per week.
Main Outcomes Measures: The residents were tested on physical characteristics, sitting and standing blood pressure, mobility (15.2 meter timed walk), and six strength measurements on a hydraulic exercise machine.
Results: Statistically significant differences pre- and post-intervention were found on several measures of blood pressure, strength, and mobility. While residents exercising less than nine minutes per week tended to remain stable or show changes in adverse directions on these measures (e.g., decreased Shoulder Press strength, p < .05), residents exercising at least nine minutes per week demonstrated positive improvements (e.g., Knee Flexion and Back Pulldown, p < .01), as well as increased mobility (p < .01). Statistically significant decreases were also found for measures of sitting and standing blood pressure (p < .05).
Conclusions: The results of this study revealed that assisted-living residents who exercised on a recumbent stepper as little as nine minutes per week decreased blood pressure, and increased strength and walking speed. This effect holds true even in the oldest-old individuals.
