He enrolled in the I. M. Sechenov 1st Moscow Medical Institute, where he graduated with a doctoral degree. After, he enrolled in the Institute of Medical and Biological Problems, Ministry of Public Health, Moscow, where he specialized in astronautics medicine.

Polyakov volunteered for his 437 day flight to learn how the human body would respond to the micro-gravity environment on long-duration missions to Mars.

. Data from Polyakov's flight has been used by researchers to determine that humans are able to maintain a healthy mental state during long-duration spaceflight just as they would on Earth.

Polyakov underwent medical assessments before, during, and after the flight. He also underwent two follow-up examinations six months after returning to Earth. When researchers compared the results of these medical exams, it was revealed that although there were no impairments of cognitive functions, Polyakov experienced a clear decline in mood as well as a feeling of increased workload during the first few weeks of spaceflight and return to Earth. However, Polyakov's mood stabilized to pre-flight levels between the second and fourteenth month of his mission. It was also revealed that Polyakov did not suffer from any prolonged performance impairments after returning to Earth. In light of these findings, researchers concluded that a stable mood and overall function could be maintained during extended duration spaceflights, such as manned missions to Mars
