Astronauts face numerous challenges in space, including the effects of microgravity on their bodies. Bone density decreases, muscles shrink, and bodily fluids shift, leading to vision problems.

To combat these effects, 12 volunteers are participating in the Bed Rest with Artificial Gravity and Cycling Exercise (BRACE) study. Conducted by the Institute for Space Medicine and Physiology (MEDES) and supported by the European Space Agency (ESA) and French Space Agency (CNES), the study investigates the effects of artificial gravity on astronauts.

Study Design

The participants, healthy men aged 20-45, are divided into three groups:

• Control group: Resting in bed for 60 days
• Bed rest with cycling: Resting in bed and exercising regularly on a cycling machine
• Bed rest with cycling and centrifuge: Resting in bed, cycling, and periodically spinning in a centrifuge to simulate artificial gravity

All participants must keep at least one shoulder on the bed at all times. They will receive payments of $19,300 over four years.

Physiological Measurements

Before and after the 60-day bed rest period, researchers will conduct a range of physiological tests, including:

• Neurological health
• Cardiovascular health
• Metabolic health
• Muscular health
• Bone health
• Urinary, blood, opthalmological, and psychological evaluations

These measurements will help scientists understand the effects of artificial gravity on the human body.

Applications for Space and Earth

Artificial gravity could improve the health of astronauts on long-duration space missions. It may also have applications for people on Earth, such as:

• Elderly individuals
• Bedridden patients
• People with musculoskeletal conditions
• People with osteoporosis

Bed rest studies like BRACE provide valuable insights into the effects of immobilization on the human body. This research can be applied to rehabilitation programs for patients recovering from surgery or serious illness.

Cycling in Bed Improves Bone Health for Astronauts

The BRACE study is the first in Europe to include cycling as part of the bed rest protocol. Researchers believe that cycling may help to maintain bone density in astronauts.

Previous studies have shown that bed rest can lead to a decrease in bone density of 1-1.5% per month. This is a significant concern for astronauts who may spend months or even years in space.

Cycling is a weight-bearing exercise that can help to maintain bone density. By incorporating cycling into the BRACE study, researchers hope to learn more about the effects of artificial gravity on bone health.

Artificial Gravity Cycling Improves Cardiovascular Health for Astronauts

Artificial gravity cycling may also improve cardiovascular health for astronauts. In space, the lack of gravity causes bodily fluids to shift, putting pressure on the heart and blood vessels. This can lead to a decrease in blood volume and a drop in blood pressure.

Artificial gravity cycling can help to counteract these effects by increasing blood flow and maintaining blood pressure. This may reduce the risk of cardiovascular problems for astronauts on long-duration space missions.

Conclusion

The BRACE study is providing valuable insights into the effects of artificial gravity on the human body. This research could lead to new ways to improve the health of astronauts in space and people on Earth with limited mobility.

What is ENO Breathe?

ENO Breathe is a virtual program that helps people recover from long-haul Covid-19 symptoms using the techniques of opera singing. Developed in partnership with the English National Opera (ENO) and the Imperial College Healthcare NHS Trust, the program teaches participants breathing exercises and vocal techniques to improve their breathing and reduce their anxiety.

How Does ENO Breathe Work?

ENO Breathe sessions are conducted via Zoom and last for one hour each. Participants learn a variety of breathing exercises, including diaphragmatic breathing and singing lullabies. These exercises help to strengthen the diaphragm, improve lung capacity, and reduce hyperventilation.

Benefits of ENO Breathe

According to data provided by ENO Breathe, 90% of participants in the pilot program reported positive improvement in their breathlessness, while 91% felt that their levels of anxiety had dropped. Additionally, 100% of participants said they would continue practicing the techniques after the program ended.

Who Can Benefit from ENO Breathe?

ENO Breathe is designed for people who are experiencing long-haul Covid-19 symptoms, such as breathlessness, fatigue, and anxiety. Participants do not need to have any prior experience with singing or music.

What to Expect in an ENO Breathe Session

ENO Breathe sessions are led by a team of doctors, therapists, and vocal coaches. The sessions are designed to be accessible and enjoyable for all participants.

• Breathing Exercises: Participants learn a variety of breathing exercises to improve their lung capacity and reduce hyperventilation.
• Vocal Techniques: Participants learn vocal techniques that are used by opera singers to improve their breathing and resonance.
• Singing Lullabies: Singing lullabies is a relaxing and soothing activity that can help to reduce anxiety and promote a sense of well-being.
• Community Support: ENO Breathe provides a supportive community for people who are recovering from long-haul Covid-19. Participants can share their experiences and support each other in their recovery journey.

How to Join ENO Breathe

ENO Breathe is available to people in England who are experiencing long-haul Covid-19 symptoms. To join the program, visit the ENO Breathe website or contact your local post-Covid clinic.

The Science Behind ENO Breathe

The breathing exercises and vocal techniques used in ENO Breathe are based on the science of respiratory physiology. Diaphragmatic breathing helps to strengthen the diaphragm, which is the main muscle responsible for breathing. Singing lullabies helps to slow down the breath and promote relaxation.

Personal Story: Sheeba’s Experience with ENO Breathe

Sheeba is a 43-year-old mother of two who experienced long-haul Covid-19 symptoms for over a year. She joined ENO Breathe in June and has since noticed a significant improvement in her symptoms.

“Before the program, I didn’t have many people to talk to about my experience,” Sheeba said. “But through ENO Breathe, I met others who were in a similar situation. Everyone had a similar experience to mine and we’re all at the same stage in our lives. Through singing, I feel rejuvenated.”

ENO Breathe Expands to Reach More Patients

Due to its success, ENO Breathe is expanding to reach more patients across England. By this fall, the program will reach 1,000 patients from more than 30 post-Covid clinics.

Online Resources

ENO Breathe offers a variety of online resources to help participants continue practicing the techniques they learn in the sessions. These resources include exercises, song sheets, and audio and video recordings.
