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

Not Applicable

Completed

• Conditions: Sleep Deprivation
• Interventions: Behavioral: Moderate intensity interval training (MITT)

• Registration Number: NCT04562857
• Lead Sponsor: Cairo University

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.

Arm && Interventions

Group	Intervention	Description
obstructive sleep apnea	Moderate intensity interval training (MITT)	interval exercises (intervention) on bicycle for patients with AF and OSA for 10 weeks, 3 times/week for duration of 30-45 min/ session.
Central sleep apnea	Moderate intensity interval training (MITT)	interval exercises (intervention) on bicycle for patients with AF and CSA for 10 weeks, 3 times/week for duration of 30-45 min/ session.

Primary Outcome Measures

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

Secondary Outcome Measures

Name	Time	Method
six minute walking distance (in meters)	10 weeks	represent aerobic capacity (distance walked in 6 min)
