Astronauts experience significant bone density loss in space. Ground-based studies, like this 90-day bed rest, show promising countermeasures for bone health in space and for bedridden patients.
Area of Science:
- Space physiology
- Bone metabolism research
Context:
- Accelerated bone density loss observed in astronauts on long-duration space missions.
- Restrictive experimental conditions in space necessitate ground-based simulations.
- European Space Agency (ESA) research since the mid-1990s focuses on causes of bone loss.
Purpose:
- To investigate potential causes of astronaut bone density loss.
- To test countermeasures against bone loss using a 90-day bed rest study.
- To generate high-resolution data for future space-based bone metabolism studies.
Summary:
- A 90-day bed rest study yielded promising data on countermeasures for bone loss.
- Findings are linked to observed phenotypes in simulated space environments.
- The study provides statistically significant and high-quality data.
Impact:
- Provides a crucial steppingstone for defining future space-based bone metabolism studies.
- Findings are directly applicable to improving recovery prognosis for long-term bedridden patients.
- Highlights the importance of activity for maintaining bone health in reduced gravity and sedentary conditions.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
