ResumoPURPOSE: The aim of this study was to investigate the effect of 30 minutes of physical exercise with elastic bands on the sleep of shift workers. METHODS: This study was approved by the Research Ethics Committee (COEP) of the UFMG. The participants were 12 male volunteers, aged between 25 and 50 years, fast rotating shift workers 4 x 1 off-road truck operators in a mining company. The volunteers had their sleep evaluated by the PSQI. In the second moment, the subjects were submitted to 2 months of short duration physical exercise intervention (up to 30 minutes) with elastic bands. The intervention phase consisted of two to four physical exercise sessions per week, lasting approximately 30 minutes per session. After the 2-month intervention period, the volunteers had their sleep evaluated by the PSQI. RESULTS: The generalized linear model (GEE, Generalized Estimated Equations) was applied to describe the effect of group and time (before and after treatment) on measures of sleep assessed by the PSQI. The following variables were considered: group and time as a fixed effect, controlled by age and time spent working on the scale. There were no significant treatment effects (POST 4,5 ± 3,3 vs PRE; 6,3 ± 3,6) for the PSQI score variable. However, it was possible to identify that the proposed physical exercise had improved the sleep of 4 (33.3%) of the workers who had poor quality sleep and started to show good sleep quality after the 2-month intervention period. - Table - Sleep evaluation data by PSQI - N (%); mean and standard deviation of sleep quality score by PSQI.
