risks of Reduced muscle size, strength
Another problem related to or related to gravity is the challenge of decreasing muscle size and endurance, which is the result of being affected by the microgravity in space, which is observed starting from flights that exceed 30 days, and these decreases include muscle atrophy, decreased strength, decreased fitness and reduced resistance to fatigue. Effects are mainly observed in the lower extremities and other postural muscles.
The process of losing muscle performance, clamping strength and fitness is well known and documented, but what is not known is the time course of changes in muscle performance during long-duration spaceflight that would affect flight missions as a whole. When muscle is lost during flight and after flight, understanding the time course is important. Critical to extend the durations of assignments.
Despite the importance of this challenge to crew health and mission performance, there are no tests or assessments that are used to determine whether the muscles are ready to travel on missions.
some solutions
Spaceflight analog studies show that resistance exercise is at least partially effective in preventing discharge-induced muscular fitness loss
For example, the International Space Station (ISS) has three main instruments
The second generation treadmill
Advanced denominator exercise
Cycle potentiometer with isolation system
This group is the ISS weapon to counter the loss of muscle fitness in space, but in Earth orbit. Although this group meets what is required of it in addressing this challenge, it can be replaced with another smaller one to suit long-haul vehicles.
These exercises can be performed on a daily or weekly basis, depending on the uploading that affects the flight crew. In addition to the resistance exercise that is performed on the equipment, there are nutritional supplements and medical preparations that also contribute to restoring muscle fitness.
