Effects of Exercise Training on Exercise Capacity and Sleep Quality in Patients With Obesity Hypoventilation Syndrome

Obesity Hypoventilation Syndrome is defined as a combination of obesity (BMI ≥ 30 kg/m2) and daytime hypercapnia in arterial blood gas analysis (PaCO2 \> 45 mmHg) without other pathologies that cause hypoventilation. Symptoms seen in individuals diagnosed with OHS are stated as a feeling of suffocation due to apnea, loud snoring, morning headache and excessive daytime sleepiness. Respiratory mechanics, respiratory muscle performance, pulmonary gas exchange, lung functions and exercise capacity parameters are adversely affected in patients. Early treatment is important so that these negative changes do not lead to worse outcomes. Weight control, bariatric surgery, pharmacological treatment and non-invasive mechanical ventilation (NIMV) are included in the treatment program of OHS patients. The effects of exercise on the treatment program of OHS patients are unknown. Considering all the studies in the literature, the primary purpose of this study is to evaluate aerobic and strength training on exercise capacity and sleep quality in patients with hypoventilation syndrome. The secondary aim is to examine the effect of this exercise training on peripheral muscle strength, emotional state, body composition and quality of life parameters. In addition, the researchers believe that this study will form the basis for further scientific studies on OHS and exercise and will make an important contribution to the literature.
