Effects of Exercise Training in Patients With Atrial Fibrillation and Sleep Apnea: A Pilot Study

Study Overview
=================
Brief Summary
-----------------
Background: There are still many gaps in research concerning the effect of different physical training modalities on sleep deprivation in the population with different types of sleep apnea. Aims: The purpose of this study was to examine the effect of moderate-intensity interval training (MITT) on patients with different types of sleep apnea.

Detailed Description
-----------------
Methods: 15 Participants aged 45-65 years were randomized into two groups: obstructive sleep apnea group (OSA), and central sleep apnea group (CSA). The training lasted ten consecutive weeks with 30 uninterrupted sessions. The actigraph together with the Pittsburg sleep quality index (PSQI) was used in sleep quality assessment. The actigraph (Actiwatch Minimitter Company, Incorporated (INC) - Sunriver, OR, USA) was placed on the non-dominant wrist and activities were monitored continuously while being recorded at one-minute intervals. The participants kept the device for a period of 96 hours, filled PSQI, and did 6MWT before the first and last training sessions.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sleep quality scores (0 is best, 3 is worst) | data about sleep from Pittsburgh sleep quality index questionnaire | 10 weeks | 
| sleep latency (in min) | time spent in bed before falling asleep (from the actigraph) | 10 weeks | 
| Total sleep time (in hours) | Total time actually slept (from the actigraph) | 10 weeks | 
| Sleep fragmentation index (in %) (the more means worse) | Index of the level of the sleep continuity (from the actigraph) | 10 weeks | 
| cutpoints | numbers displayed on the actigraph to give a picture about activity level | 10 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| six minute walking distance (in meters) | represent aerobic capacity (distance walked in 6 min) | 10 weeks |
