Strength Training and Light Physical Activity Reduces the Apnea-Hypopnea Index in Institutionalized Older Adults

Published:October 04, 2014DOI:https://doi.org/10.1016/j.jamda.2014.08.006

      Abstract

      Objectives

      To determine the effect of 7 weeks of resistance training and walking on the apnea-hypopnea index (AHI) in institutionalized older adults compared with a usual care control group.

      Design

      Secondary analysis of data from a randomized controlled trial.

      Setting

      Ten nursing and 3 assisted living facilities in Arkansas.

      Participants

      Institutionalized older adults.

      Interventions

      Exercise group (EG) performed supervised resistance training to arm and hip extensors on 3 days a week with additional 2 days a week of light walking. Usual care group (UC) participated in the usual activities provided within their living facility.

      Measurements

      Two nights of polysomnography before and following 7-week intervention.

      Results

      Adjusted means in the EG group showed a decrease in AHI from 20.2 (SD ±1.3) at baseline to 16.7 (SD ±0.9) at 7 weeks. Absolute strength gains were not associated with improved AHI.

      Conclusion

      Supervised resistance training and light walking reduced the severity of obstructive sleep apnea in institutionalized older adults.
