- During ageing, both quality and quantity of sleep decline, contributing to reduced quality of life, obesity, hypertension, diabetes, glucose intolerance, metabolic syndrome and heart disease.
- Obstructive sleep apnea (OSA) is characterized by fragmentation and increased respiratory events including apneas with hypoxemia.
- 8 weeks of respiratory muscle training (RMT) decreased number of awakenings, apnea and hypopnea, and desaturation on REM and NREM sleep in older persons with OSA.
RMT effectively improves sleep quantity and quality and reduces apnea in people with OSA.
Sleep parameters included:
All of the above were assessed both before and after eight weeks of respiratory muscle training in older patients (aged 60 – 85) with sleep disorders and apnea. Results were compared to a low intensity IMT control group.
RMT significantly decreased number of awakenings, apnea and hypopnea, as well as desaturation of REM and NREM sleep.
RMT significantly improves sleep quantity and quality, with a severe reduction in apnea in older patients with sleep disorders.
