  • Individuals diagnosed by a pulmonologist within the past year who initiated CPAP therapy no more than 12 months ago and demonstrate regular use
  • Individuals with habitual snoring
  • Individuals who have not participated in OSA-focused physiotherapy interventions within the past 3 months

Who cannot take part

  • Medical contraindications to physical activity according to American College of Sports Medicine (ACSM) guidelines, such as unstable coronary artery disease or decompensated heart failure
  • History of stroke or significant respiratory, neuromuscular, inflammatory, or other disorders causing hypercapnia
  • Craniofacial abnormalities, severe upper airway obstruction, or secondary respiratory diseases such as chronic obstructive pulmonary disease (COPD)
  • Body mass index (BMI) >40 kg/m²
  • Severe substance or alcohol dependence
  • Regular use of sedatives, muscle relaxants, or opioids that may affect sleep patterns
  • Pregnancy or postpartum period (<6 months)

About the trial

What the trial wants to find out

Although exercise and physical activity have shown beneficial effects in individuals with obstructive sleep apnea (OSA), evidence regarding the effects of daily physical activity habits on sleep quality and respiratory parameters remains limited. This study aims to investigate these associations in individuals with OSA.

The 2 groups in the trial

  • Control Group (CG)No study treatment, for comparison

    Participants will continue using physician-prescribed continuous positive airway pressure (CPAP) therapy and will be instructed to use CPAP every night for 24 weeks. No additional physical activity education will be provided as part of the study intervention.

  • Physical Activity Education Group (PAEG)Treatment being tested

    Participants will receive physical activity education at baseline, supported by visual materials and brochures. The education will include moderate-intensity aerobic and muscle-strengthening activities in accordance with established physical activity guidelines. Participants will be contacted periodically to assess adherence to physical activity recommendations. Participants will continue their prescribed CPAP therapy throughout the 24-week study period.

    Treatment: Physical Activity Education

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
