The effects of resistance exercise on obstructive sleep apnea severity and body water content in older adults: A randomized controlled trial.

Objectives/background: The prevalence of obstructive sleep apnea (OSA) in people over 70 years can reach up to 95%. Aerobic or combined exercise programs have been shown to impact positively on OSA severity. Resistance training changes leg fluid retention.

Effects of exercise on sleep symptoms in patients with severe obstructive sleep apnea.

Objective: To investigate the extent to which exercise is associated with symptoms in patients with severe obstructive sleep apnea (OSA).

Methods: We included subjects with an apnea-hypopnea index (AHI) > 30 events/h who completed validated sleep and exercise questionnaires. We compared symptom frequency/scores between exercisers and nonexercisers, adjusting for the usual confounders.
