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

Abstract

Introduction:The effects of high-intensity interval training (HIIT) combined with resistance training (RT) in adults with obesity and sleep-related breathing disorders (SRBDs) is limited.Objective: This study aimed to examine the effects of HIIT combined with RT on subjective sleep disorders in adults with obesity and SRBDs. Material and Methods: This 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 (VO 2 max), muscle strength using 1-repetition maximum, anthropometric variables, and blood biomarkers were examined at baseline and after 6 weeks of training. Results: The 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 VO 2 max 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). Conclusion: Six weeks of HIIT combined with RT has beneficial effects on subjective sleep disorders, estimated VO 2 max, muscle strength, and most anthropometric variables in adults with obesity and SRBDs.

Home-Based Aerobic Interval Training Combined with Resistance Training Improved Daytime Dysfunction in Adults with Obesity and Sleep-Disordered Breathing

“…20 However, these studies prescribed a centerbased exercise program tailored by the researchers, which was different from the present study. 19,20 The center-based training may have fewer confounding factors and be easier for the participants to follow the study protocol. However, the home-based AIT combined with RT in our study was safe, practical to follow in general, and especially feasible to prescribe to obese adults with SDB because none of the participants reported any serious events during exercise.…”

“…Recently, the studies have investigated the effects of a HIIT program in obese adults with SDB. 19 20 These studies showed an improvement in sleep indices 19 and subjective sleep disorders. 20 However, these studies prescribed a center-based exercise program tailored by the researchers, which was different from the present study.…”

“…The sample size was calculated based on a previous study 20 using G-Power software (Version 3.1). Sleep variables including EDS (effect size = 1.10) and the Berlin Questionnaire (category 2) (effect size = 0.85) were used to calculate the sample size.…”

“… 17 18 Supervised training at centers is commonly used to examine the effects of AIT or HIIT programs in SDB patients found to improve sleep indices and subjective sleep disorders. 19 20 However, there have been many restrictions to performing such center-based training programs with individual supervision due to the coronavirus disease 2019 (COVID-19) pandemic. 21 Therefore, home-based AIT combined with resistance training (RT) was chosen in this study to gain the maximum effect 16 in adults with obesity and SDB.…”
