Brief Summary

The objective of this study is to examine the accurate circadian variation of cardiac autonomic function by space flight. The crew will wear an Actiwatch for 96-hour and an electrocardiograph (ECG) for 48-hour. The crew conducts two In-flight data collections along with pre- and post-BDC.

Expeditions Assigned

31/32,33/34,35/36,37/38,39/40

Previous ISS Missions

We conducted continuous 24-hour RR intervals measurement in ten crews for preliminary data of this project. The preliminary data showed various changes on biological rhythms and some biological rhythm of crews showed prolonged for 24hours or more than those before and after flight.

Experiment Description

Research Overview

• To clarify the change of an accurate biological clock from space circumstance.



• We will evaluate continuous 48-hour RR intervals measurement on Holter ECG ,and sleep/wake rhythm on actiwatch for 96-hour.



• This research will be analyzed for improving the health care technology of long duration astronauts, for checking out the difference of them between before and after the flight on the earth and during long-duration space flight.
