Effects of six weeks high-intensity interval training and resistance training in adults with obesity and sleep related breathing disorders.

Abstract

IntroductionThe effects of high-intensity interval training (HIIT) combined with resistance training (RT) in adults with obesity and sleep-related breathing disorders (SRBDs) is limited.ObjectiveThis study aimed to examine the effects of HIIT combined with RT on subjective sleep disorders in adults with obesity and SRBDs.Material and MethodsThis study was a pre- and post-test design. Seventeen adults with obesity and SRBDs were recruited into the study. They received 24 minutes of HIIT and 30 minutes of RT, 3 times/week for 6 weeks. The Epworth sleepiness scale (daytime sleepiness), Berlin questionnaire (snoring and daytime sleepiness category), estimated maximum oxygen consumption (VO2max), muscle strength using 1-repetition maximum, anthropometric variables, and blood biomarkers were examined at baseline and after 6 weeks of training.ResultsThe Epworth sleepiness scale, Berlin questionnaire (daytime sleepiness category), and the number of risks associated with sleep apnea using the Berlin questionnaire were significantly decreased after 6 weeks of training (all p<0.01). The estimated VO2max and muscle strength were significantly increased at Week 6 (all p<0.05). Body weight, body mass index, % body fat, and hip circumference were significantly decreased at Week 6 (all p<0.05). No significant changes were observed in blood biomarkers, except for fasting blood glucose (p<0.01).ConclusionSix weeks of HIIT combined with RT has beneficial effects on subjective sleep disorders, estimated VO2max, muscle strength, and most anthropometric variables in adults with obesity and SRBDs.
