Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

To evaluate changes in heart rate variability (HRV) after the six-minute walk test (6MWT) in nurses following a night shift and explore the impact of night shift work on the regulation of the autonomic nervous system in the heart.

Thirty-five female nurses, with a mean age of 28.7 years (range 21.0-37.0 years), participated in this study. On the first and second mornings after a night shift, the nurses performed the 6MWT. During the test, electrocardiogram (ECG) signals, blood pressure, and walking distance were recorded simultaneously.
