The elastic band of penguin suit is aimed at the effects of weightlessness on astronauts' cardiovascular system, bones and muscles. In order to prevent muscle atrophy caused by weightlessness, in the space station, in addition to running platforms, bicycles and tensioners, astronauts will also wear penguin suits to alleviate the situation caused by weightlessness.
The two adjusting rings on the chest strap of penguin suit are used to adjust the tightness of the elastic band on the chest. These straps bind the human body tightly, so that the muscles can maintain a certain tension for a long time, which can effectively prevent muscle atrophy caused by weightlessness. The name of this suit is penguin suit.
Common sense of using space penguin suit
There are many elastic bands in the astronaut's "penguin suit", such as a stretcher for exercise on the ground. After the astronauts put it on, the muscles are tensioned by elasticity to avoid muscle atrophy. Bagging for astronauts' thighs. Its function is to prevent microgravity from affecting the distribution of body fluids, such as causing too little blood in the brain.
Otherwise, because there is no gravity, most body fluids will flow back to the legs, which will have adverse effects on the human body. "Shenzhou 9" astronauts wear "penguin suit" and bag 1-2 hours every day.
The elastic band of "penguin suit" is a bit like a stretcher on the ground. Astronauts can exercise their muscles through the action of force after wearing it. This kind of weightlessness protection countermeasure equipment can be covered outside the astronauts' daily clothes. After entering Tiangong-1, the three astronauts will wear "penguin suits" for at least 8 hours every day and train 1 to 2 hours every day.
