Astronaut's Energy Requirements for Long-Term Space Flight (Energy) - 09.17.14
ISS Science for Everyone
Science Objectives for Everyone
Astronaut's Energy Requirements for Long-Term Space Flight (Energy) measures change in energy balance in crewmembers following long term space flight. Energy also measures adaptations in the components of total energy expenditure of crewmembers, so that an equation to determine the energy requirements of crewmembers during space flight 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 space flight.

Previous ISS Missions
- With the construction of the International Space Station and the related planned long-term human missions beyond low Earth orbit, the interest in nutrition as a countermeasure to the effects of space flight has increased dramatically. A growing body of data suggests a direct relationship between nutrition and the effects of space.
- The maintenance of energy balance appears critical but difficult during space flight. Clearly the determination of energy requirements is necessary for recommending healthy nutrition in weightlessness.
- Astronaut's Energy Requirements for Long-Term Space Flight (Energy) measures changes in energy balance after long term spaceflight, adaptations in the components of the total energy expenditure and derive an equation for the energy requirements of astronauts.
Astronaut's Energy Requirements for Long-Term Space Flight (Energy) determines the crewmembers energy requirements for long-term space flight. There is no compensation for severe negative energy balance during space flight.. This energy deficit affects all physiological functions. Energy measures changes in energy balance after long-term space flight, adaptations in the components of the total energy expenditure, and help to derive an equation for the energy requirements of crewmembers.
The knowledge of energy requirements for space flight 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 pre-requisite for planned long-term manned space flight.
The techniques used within this research for assessment of energy expenditure are also used for assessment of energy expenditure on Earth.
