Comparison of Physical Activity Regimens as Treatments for Obstructive Sleep Apnea

November 22, 2011 updated by: Christopher Kline, University of South Carolina

Exercise: A Novel Treatment for Obstructive Sleep Apnea

The purpose of this study is to compare the efficacy of two different physical activity regimens as complementary or alternative treatment options for the treatment of obstructive sleep apnea. A secondary purpose of the study is to examine the effects of these activity regimens on various health consequences of obstructive sleep apnea, including blood pressure, systemic inflammation, and daytime functioning.

  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: moderate-intensity exercise training
Individuals will complete four days of aerobic exercise of moderate intensity (60% of maximal VO2, approximated from heart rate). Duration of aerobic activity will gradually increase from weeks 1 through 4 until 180 min of aerobic exercise at the prescribed intensity is performed each week. Following aerobic exercise on two days per week, moderate-intensity resistance training will be performed using eight different resistance machines. One set of 8-12 repetitions will be performed during weeks 1-4; from week 5-on, 2 sets of 8-12 repetitions will be performed.
Active Comparator: low-intensity stretching
Individuals will perform supervised whole-body flexibility exercises on two days per week. Two sets of each exercise will be performed, with the duration of each stretch gradually increasing from 15 sec to 30 sec. A total of 15-20 stretches, focusing on whole-body flexibility, will be performed.
