ABSTRACT
ObjectiveTo explore the effectiveness of mindfulness yoga training on sleep quality in college students， so as to provide references for the intervention of sleep problems in college students. MethodsFrom March 28， 2021 to April 20， 2021， A sample of 45 college students with Pittsburgh Sleep Quality Index （PSQI） score ≥8 was recruited. Participants were randomly divided into study group （n=22） and control group （n=23）. Participants in the intervention group received mindfulness yoga training twice a week for 4 weeks. The control group did not receive mindfulness yoga training during the trial， but the same training would be given after the trial. Before and after the intervention， PSQI and the N-back training tasks were used to evaluate the sleep quality and working memory ability of the two groups. ResultsThe main effects of time on the PSQI total score， the accuracy and reaction time of N-back training task were statistically significant （F=37.240， 6.898， 10.775， P<0.05 or 0.01）. The main effects of grouping factors on PSQI total score and the accuracy of N-back training task were statistically significant （F=8.057， 11.093， P<0.05 or 0.01）. The interaction of time and group had statistical significance on PSQI total score and the response time of the N-back training task（F=32.730， 17.578， P<0.01）. After intervention， the PSQI total score of the study group was lower than that before intervention （F=69.898， P<0.01）， and the response time of N-back training task was shorter than that before intervention （F=27.939， P<0.01）， the differences were statistically significant. ConclusionGroup mindfulness yoga training may help improve the sleep quality of college students.
