Abstract
Purpose: The purpose of this study was to examine the effects of short-term resistance training on sleep quantity and quality in young women, according to their body fat.
Methods: Thirty-five young women were randomly assigned based on their body fat levels, using the 90th percentile of fat mass as a criterion, with a threshold set at ≥ 21 kg of fat mass for the obese group (n = 16) and < 21 kg of fat mass for the non-obese group (n = 19). Subjective sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI) at pre and post a progressive six-week full-body resistance training (RT).
Results: Post-intervention analysis showed a reduction in the overall sleep score (p = 0.006, η2 = 0.21), improvement in subjective sleep quality (p < 0.001; η2 = 0.357) and a decrease in sleep disturbances (p = 0.034; η2 = 0.129). However, no interaction between group x training for sleep parameters and body composition was observed (p > 0.05). There were no significant correlations between sleep quality, fat mass and fat-free mass in both groups investigated (p > 0.05).
Conclusion: Six-weeks of RT improved subjective sleep quality and reduced sleep disturbances in young women, regardless of the amount of fat mass. Sleep variables were not associated with changes in body composition.
期刊介绍：
The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep.
Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
