ISS Science for Everyone

Science Objectives for Everyone
The objective of The effect of long-term microgravity exposure on cardiac autonomic function by analyzing 48-hours electrocardiogram (Biological Rhythms 48hrs [for 1YM]) investigation is to examine how the body’s “biological clock” affects cardiac (heart) function during spaceflight. Crew members wear an Actiwatch that monitors rest and activity cycles for 96 hours, and an electrocardiograph (ECG) to measure heart function for 48 hours. Three inflight data collections are taken, along with preflight and postflight baseline data collection (BDC).

Experiment Description

Research Overview

  • The goal of The effect of long-term microgravity exposure on cardiac autonomic function by analyzing 48-hours electrocardiogram (Biological Rhythms 48hrs [for 1YM]) is to clarify how an accurate biological clock changes with spaceflight.
  • Biological Rhythms 48hrs (for 1YM) evaluates continuous 48-hour rest and relaxation (RR) intervals measurement on a Holter electrocardiograph (ECG), and sleep/wake rhythm on an Actiwatch for 96-hours.
  • This research is analyzed for improving the health care of crew members on long duration space flight, by comparing the crew member’s cardiac autonomic function before, during, and after flight.

Operations

Operational Requirements and Protocols
Data is collected 3 times throughout the 1 year crew mission for Biological Rhythms 48hrs (for 1YM): at Flight Day (FD) 21 (+/-7 days), FD160~170 days, and Return (R) -1~3 weeks.
