GENERAL KNOWLEDGE

Detailed explanation-1: -Bone loss and kidney stones are well-known as essential problems for astronauts to overcome during extended stays in space. Crew members engage in physical exercise for 2.5 hours a day, six times a week (15 hours a week) while in orbit to avoid these issues.

Detailed explanation-2: -They will exercise approximately two hours every day using exercise machines, such as treadmills and ergometers. The treadmill is a machine on which, the astronauts do running exercises with their bodies strapped to it. The Ergometer is a machine similar to a bicycle without wheels.

Detailed explanation-3: -Meals should be nutritionally balanced with calcium-rich foods (milk, small fish, etc.) and vitamin D (fish, mushrooms, etc.). Limited sunbathing is also important for activation of vitamin D. Physical exercise to increase bone load and muscle training should also be integrated into each person’s daily life.

Detailed explanation-4: -Exercise helps to keep both your bones and muscles strong. That makes it key to helping astronauts reduce the amount of bone loss they experience in space. To reduce bone loss, astronauts must exercise for a minimum of 2 hours per day.
