Effect of Lemian exercises on the sleep quality of soldiers during a long voyage
Objective To explore the effect of Lemian exercises on the sleep quality of soldiers during a long voyage,in order to provide an effective method for improving their sleep quality during navigation.Methods A total of 127 people who had poor sleep quality during a long voyage were selected as research objects.They were randomly divided into intensive training group(n=43,complete the exercise every day during the set time),self-training group(n=42,free to complete the exercise every day)and control group(n=42,routine sleep health education).The Pittsburgh sleep quality index(PSQI),sleep quality improvement and satisfaction with the intervention were investigated before training,after 4 weeks of training and after 8 weeks of training.Results The PSQI scores of the three groups were significantly decreased after 4 weeks of training(P<0.001),but there was no statistical difference in the PSQI score or sleep quality improvement rate among the three groups(P>0.05).The PSQI scores after 8 weeks of training were significantly lower than those after 4 weeks of training in the three groups(P<0.001).The sleep quality improvement rate after 8 weeks of training was higher than that after 4 weeks of training in both intensive training group and self-training group(P<0.05).After 8 weeks of training,the PSQI scores of the intensive training group and self-training group were significantly lower than that of the control group(P<0.05),and the sleep quality improvement and satisfaction rates of the intensive training group and self-training group were significantly higher than those of the control group(P<0.05).There was no significant difference in the PSQI score,sleep quality improvement,or satisfaction rate between the intensive training group and the self-training group(P>0.05).Conclusion The sleep quality of naval soldiers can be improved by Lemian exercises during leisure time of long voyage.However,the efficiency of the exercise is slow,and it is recommended to start practicing in advance.
