About this study

Medical staff with sleep disturbances due to their night-shift work were randomized to either a treadmill walking session for 47 minutes with moderate intensity (the heart rate reaches 70~75% of the maximum heart rate), treadmill running section for 28 minutes with intermittent high-intensity (the heart rate reaches 90~95% of the maximum heart rate for 4 minutes and 50~70% for 3 minutes), or a quiet-rest control, 14 hours before undertaking a continuous night shift. Sleep quality was assessed by ActiGraph with subjective questionnaire for 1 night and 3 nights after exercise. Tests were performed (t-tests or χ2 tests) to test for differences between any two of the three intervention trials.
