| Summary: | Menopause is associated with decreased physical activity and sleep disturbances. Short sleep duration and poor sleep quality have been associated with an increased risk of falls, obesity, and type 2 diabetes. It´s important to understand how physical activity influences sleep health in postmenopausal women. The purpose of this study was to analyse the variation of sleep duration and quality as a function of moderate-vigorous physical activity (not recommended, MVPA<150 min/week; recommended, MVPA between 150 and 300 min/week; highly recommended, AFM>300 min/week). The sample included 40 postmenopausal women (57.28±5.68 years) enrolled in the Meno(s)Pause+Movement, 85% documenting the use of hormone therapy. Sleep (TST, total sleep time; SOL, sleep onset latency; SE, sleep efficiency; SFI, sleep fragmentation index) and physical activity were estimated using ActiGraph GT3X+ activity monitors. Physical activity was classified according to WHO (2020) guidelines and body composition was measured using bioimpedance (InBody 120). One-way ANOVA was used to compare the means of the variables in the MVPA groups being considered a 5% degree of statistical significance. Women taking medication that influenced sleep were eliminated from the analysis. The research was approved by the Ethics Committee of the UTAD (ref. Doc77-CE-UTAD-2022). Most of the sample showed fat mass ≥35% (65%) and visceral fat >9 points (72.5%). The average MVPA was 299,05 min/week, with 30 women showing levels of at least 150 min/week. All participants presented SFI>5 number of events (25,66±6,38 number of events) and SOL£30 minutes (2.83±1.29 min). The average TST was 7.38 (±0.50) min/day, with 75% showing recommended values. The MVPA groups did not produce a differentiated effect (p>0.05) on the parameters related to the duration and quality of sleep. There is no relationship between MVPA and sleep duration and quality in postmenopausal women. A replication study in a larger sample is suggested.
