Question

. Congratulations - right after your graduation, you get hired by NASA! The chief NASA scientist hires you to submit a design for an exercise training regime for a round-way trip Mars (estimated to take at least 1.5 years). Given that the M-MED is protected by trademark, and NASA doesn’t want to pay for it, you may use any other sports equipment in existence, or come up with a novel solution. Your prospectus should explain to the NASA beancounters what changes occur in the human musculoskeletal system in space, and why they are a “mission risk”. You should then elaborate on how your machine(s) and training regimen reverses or prevents these changes in microgravity. Your answer should include some detail how the machine(s) works, what muscles and bones it loads, and why it is effective in maintaining the aerobic capacity and strength in astronauts, so that they can arrive fit and ready to work on Mars (and not just lounge about)

-->Gravity on Earth goes about as a gift for us. It is with the assistance of this gravity that blood and different liquids stream down from the heart into our appendages and different pieces of our body effectively. In any case, when in space, the nonappearance of gravity can cause genuine cardiovascular issues in space explorers since it doesn't require any push to drift around and reach up to the head. This can cause pressure in the optic nerve and as an outcome issue with vision. Nonetheless, there are a few muscles of our body like the soleus and adductor longus present in our appendages which help us stand erect on Earth against gravity. The legs are significant for us people performing bipedal velocity since they are the ones conveying the heap of the entire body around. Be that as it may, in space, the muscles of the legs are the parts which wilt away first without gravity. Without gravity, bones lose minerals at a lot quicker rate contrasted with old individuals having osteoporosis on Earth. The bone thickness diminished at a rate of 1% every month without gravity contrasted with 1-1.5% every year in the older on our planet. Without legitimate exercise or nourishment space explorers additionally, face muscle quality and continuance misfortune inside a couple of months. Abatement in bone thickness expands the blood calcium level which thusly can likewise cause renal stones bringing on additional difficulties. In this way to make up for gravity within the sight of microgravity in spaceships/space stations, space travelers need to perform thorough activities for in any event 2-3 hours for six days seven days to stay fit and work on landing on Mars.

-->When all is said in done high force low volume activities help to limit the wilting of muscles, bones and cardiovascular capacities. Generally, a typical treadmill or even a stationary bike can help keep up oxygen-consuming condition of the musculoskeletal framework. Bridles are clearly appended to the space explorers else they would skim and not have the option to keep up their position on the strolling surface. Utilization of confounded machinery are additionally unrealistic in spaceships since the utilization of a huge number of stray pieces is not sheltered in repulsive force or miniaturized scale gravity conditions. Therefore straightforward machines which would give draw and contort extending elastic groups joined to pulleys can be utilized for overwhelming weight squats, bowing activities for the legs and arms and so forth helping inappropriate support of the muscles and bones. Pressure sleeves around the thighs can likewise keep the liquids in the lower furthest points instead of gliding up to the higher pieces of the body.
