Gravity
Gravity
The force that pulls all objects towards each other, most notably towards the Earth, influencing movement, the force we feel on our feet when standing, and the ease of movement when lying down.
Whole Body Vibration Technology
Whole Body Vibration Technology
A technology involving vibrations that simulates the effects of increased gravity exposure.
Risks of Prolonged Sitting
Risks of Prolonged Sitting

Study Notes
Gravity and Health
- Whole body vibration technology is not an invention of the Soviet space program, but is a technology studied by NASA and the European Space Agency.
- Images depict situations reducing gravity exposure: astronauts in space, divers underwater, elderly in wheelchairs, those in hospital beds, and children sitting.
- Gravity pulls from head to toe, pressing on feet when standing.
- Changing position, like lying down, alters gravity's effect.
- Lying down distributes weight, reducing stress on feet.
- Astronauts train underwater to mimic microgravity due to water buoyancy reducing gravity's impact.
- Prolonged reduced gravity causes muscle weakness, bone loss, and body deterioration.
- NASA studied bed rest effects on volunteers to understand reduced gravity's impact.
- Prolonged sitting increases heart disease, type-2 diabetes, obesity, and emotional issues risk.
- The head-down bed rest model for space travel simulation negatively impacts the body more than flat bed rest.
- Post-7-day bed rest changes mirror those in elderly nursing home residents.
- Gravity is most impactful during 0 to 20 years of age.
- Reduced gravity (e.g., prolonged sitting, lying down) hastens aging and health problems.
- Increasing gravity exposure can counter negative effects and promote healthy aging.
- Australians sit an average of 481 minutes daily, 337 minutes at a computer.
- Only 73 minutes remain for standing and exercise daily.
- Hypervibe machines use whole body vibration for increasing gravity exposure and improving health.
