Objective To understand the effect of Baduanjin combined the resistance training of elastic band on the perceived stress and sleep quality of special service recuperating officers and soldiers， and provide a reference for the maintenance of the physical and mental health of the recuperating officers and soldiers. Methods Totally 68 young and middle-aged recuperating subjects who were concentrated in a special service recuperation center in July 2019 were selected. The subjects were randomly divided into control group and intervention group using a random number table method. 30 in the control group received conventional recuperation， while 38 in the intervention group were given extra Badanjin combined resistance training of elastic band exercise for four weeks. The Pittsburgh Sleep Index Questionnaire（PSQI） and the Chinese version of the Perceived Stress Scale（CPSS） were used to evaluate the perceived stress and sleep quality of recuperating subjects before and after the intervention，describe the overall sleep status and analyze and compare the subjects' perceived stress level under different sleep indicators and its correlation. Results Before the intervention， the positive rate of sleep disorder among special service recuperating officers and

soldiers was 51.47%. After intervention， the score of CPSS and PSQI of the intervention group was 20.66±5.41 and 4.45±2.61，

which were significantly lower than before the intervention（P<0.05）. The CPSS score of control group was 27.90±7.29， which was not significantly lower than before（P>0.05）， and the PSQI score was 6.50±2.58， which was lower than before （P<0.05）. The CPSS score and improvement of PSQI of the intervention group were significantly higher than those of the control group， and the differences were statistically significant （both P<0.01）. Conclusion The special service recuperating officers and soldiers have higher level of perceived stress and poor sleep quality. Baduanjin combined resistance training of elastic band can significantly reduce the stress levels and improve their sleep quality.
