High-intensity interval training improves obstructive sleep apnoea

BackgroundThree hours per week of vigorous physical activity is found to be associated with reduced odds of sleep-disordered breathing.AimTo investigate whether 12 weeks of high-intensity interval training (HIIT) reduced the apnoea–hypopnea index (AHI) in obese subjects with moderate-to-severe obstr...

Summary:BackgroundThree hours per week of vigorous physical activity is found to be associated with reduced odds of sleep-disordered breathing.AimTo investigate whether 12 weeks of high-intensity interval training (HIIT) reduced the apnoea–hypopnea index (AHI) in obese subjects with moderate-to-severe obstructive sleep apnoea.MethodsIn a prospective randomised controlled exercise study, 30 (body mass index 37±6 kg/m2, age 51±9 years) patients with sleep apnoea (AHI 41.5±25.3 events/hour) were randomised 1:1 to control or 12 weeks of supervised HIIT (4×4 min of treadmill running or walking at 90%–95% of maximal heart rate two times per week).ResultsIn the HIIT group, the AHI was reduced by 7.5±11.6 events/hour (within-group p
