ASTRONAUT'S ENERGY REQUIREMENTS FOR LONG-TERM SPACE FLIGHTS (ENERGY)
Research Area: Integrated Physiology and Nutrition
Expedition(s): 29-ongoing
Principal Investigator(s): ● Stephane Blanc, PhD, University of Strasbourg, France


RESEARCH OBJECTIVES
Astronaut's Energy Requirements for Long-Term Space Flights (Energy) measures change in
energy balance in crew members following long-term spaceflight. Energy also measures
adaptations in the components of total
energy expenditure of crew members,
so that an equation to determine the
energy requirements of crew members
during spaceflight may be derived. Such
knowledge of energy requirements is of
a great importance to ensure health,
good performance, and the overall
success of a mission, and also
contributes to ensure adequate
exercise load and cargo allotments for
food during spaceflight.


EARTH BENEFITS
The techniques used within this
research for assessment of energy
expenditure are also used for
assessment of energy expenditure on
Earth.

SPACE BENEFITS
The knowledge of energy requirements for spaceflight is needed to ensure health,
performances, and the overall success of a mission. In addition, it will contribute to ensure
adequate, but not excessive, cargo supplies for food. In this regard, the determination of
energy requirements as a function of exercise load is a prerequisite for planned long-term
manned spaceflight.


RESULTS
No final results are available yet as the experiment is ongoing


This investigation is ongoing and additional results are pending publication.
