What is the physical training of an astronaut like?

Physical activity is important for the physical and psychological maintenance of astronauts. Learn how astronauts stay fit in space in this article.

exercise isn’t just for terrestrial athletes, because Astronaut they also need stay in top shape while they are in space. But how do astronauts train before they go into space and once there? This is one of the requirements to become a NASA astronaut.

All NASA astronauts experienced the weightlessness of space. influence long term All that time spent in a zero gravity environment weakens the human body. spaceflight normally lead muscle atrophy already one Decreased bone density. To prevent this, or at least limit the damage as much as possible, NASA has excellent athletic trainers and physical rehabilitation technicians on staff. this is for astronauts Get in shape for spaceflight. These trainers also teach astronauts how to keep their bodies in ideal shape during flight and then work with them to restore their fitness after returning to Earth.

coaches have evolved multiple exercise and strength training programs for different phases of the mission. they mainly focus multi-joint exercises, Weight bearing and lower body. With this they intend to address the various parts of the body that are usually more vulnerable to gravity’s lack. As you indicated, it is highly likely that muscle atrophy and loss of bone density occurs in the lower body. the reason is less used arms and torso Due to weightlessness in space therefore activities like standing and walking allow our muscles and bones continuous training on earth; But this does not happen in space.

NASA’s research and development on training programs and machinery to prepare, maintain, and rehabilitate astronauts has contributed substantially to the general body of knowledge in physiology. (Exercise Science). Also, as a result, there are physical therapy and exercise equipment inspired by NASA and they are commercially available.

All studies done by NASA on the various effects of space travel on the body (studies that started at the beginning of the space program before anyone left Earth) have shown that prolonged exposure to low-gravity environments The lack of space leads to a severe loss of calcium in the bones, malformed blood cells, and an extra layer of fat (related to decreased levels of physical activity) around the heart. for all this, NASA doctors Post-flight examinations of astronauts due to loss of bone and muscle density. The North American space agency has decided it must develop specific exercise programs and equipment for space. Special physical needs of astronauts. With all of these efforts in mind, it’s no wonder how much astronauts get paid.

Space Physical Exercise: Shuttle

Prior to the launch of NASA’s Skylab space station in 1973, the US space agency leased it boeing engineer gary graham To design a cardiovascular exercise machine. it must be keep astronauts’ hearts in shape And will also optimize your blood flow. Astronauts needed to be able to use this machine in space as well, so Graham and his team at NASA eventually created an exercise machine for astronauts called the CMC Shuttle 2000.To use the CMC Shuttle, astronauts lie on their backs On a platform that slides on rails. They then take their feet off a protective plate and then stand up, holding on to adjustable bungee cords that create resistance. with each iteration, The machine moves the user’s diaphragm and that the chest cavity of astronauts is exercised, returning blood to the heart and helping to maintain heart health and overall circulation at acceptable levels.

Live Training

For example, NASA astronaut used cmc shuttle skylab mission 84 days from 1973 to 1974. Based on observations of the heart, muscles and blood circulation of astronauts using it in flight, further improvements to the design have been made. Without going further, a company called contemporary design In 1991 Graham and licensed the technology from NASA to produce commercially available instruments Shuttle 2000-1. Found primarily in physical diagnosis and rehabilitation settings, it is one of the few machines used by bedridden patients. L Shuttle 2000-1 Not only does it keep these patients’ hearts in good shape and keep their blood flowing properly, but it also Prevents atrophy of unused bones and muscles. Astronauts’ physical activity is a recurring question about life in space, such as how astronauts go to the bathroom.

Top Athletes Use It Too Shuttle 2000-1. The exercises performed on this machine, called plyometrics, offer activities Powerful and rapid muscle contraction. These exercises treat the muscles like coiled and weighted springs. huge explosion of speed and power when they are released. So, whether for rehabilitation needs, for pure maintenance or to take the body to the next physical level, this machine developed by NASA for astronauts makes it possible.

In the late 1980s, NASA researchers robert whalen He was tasked with finding ways to help astronauts maintain their strength with novel in-flight exercises. to maintain the human body in space general physical condition, The exercise requires weights to simulate the real effects of gravity on Earth. Whalen proposed the use of differential atmospheric pressure in spaceflight activities and exercises. load on astronauts Will mimic gravity with air when exercising, thus preventing the breakdown of bones and muscles.

Until then, mid flight exercise It was difficult and flawed for the astronauts. NASA’s standard equipment was an antigravity treadmill. The astronauts were somehow tied to the machine in order to stay in place. It was not only uncomfortable, but it was also suppressed muscle movement Who had to help Whalen then modified the treadmill concept by calibrating the high air pressure forces specifically to match effect of gravity Must be on the astronaut in question.

Whalen’s Coach

Whalen’s Coach It’s like a treadmill embedded in a bouncy castle. The user climbs into a sealed hole above the tread. once there, astronauts must run or walk, and the machine calibrates the inflatable sections to lift the body needed to push, applying air pressure to the astronaut’s weight lower body back And manually providing the same service that gravity does naturally.

Change-G-Run-Antigravity

In 2005, NASA and Whalen licensed the G-Trainer patent to a company called Alter-G, Inc. who adapted the machine for medical use and sports training. your antigravity treadmill Alter G aids in the physical rehabilitation of patients Decreased strength in the lower part of the body. But there’s a big difference between this and the NASA model, because technically the treadmill does the opposite on Earth of what it does in space. In space, air adds weight and provides healthy resistance. Lose weight on earth. Today, the G-trainer (G-trainer) is widely used Rehabilitation Center, Military Hospital and in training centers for professional and university sports teams.

NASA actively shares all of its knowledge with the athletic training community, even going so far as to offer athletic boot camps. Open to students pursuing a career in sports coaching, the internship provides valuable real-world experience. physical therapy and rehabilitation of muscles and bones are covered, as are actual physical evaluations of patients (including astronauts). Interns also have the opportunity to help design rehabilitation and training programs.
