In 2020, specialists trained in Central Russia for an Arctic airdrop from an altitude of 10 km onto islands in the Arctic Ocean. Participants performed their first airdrop from a turbojet military transport aircraft.

This study will look at how the body changes during training for high-altitude parachute jumps from 8 to 10 kilometers.

The Varicard and Holter Life systems, along with ISCIM6.0 software, were used to monitor heart rate changes over short periods. Researchers took measurements from the moment they prepared to board the aircraft until they arrived at the unit’s location after the jump. The following stages were taken into account in the electrocardiogram analysis: a state of rest in the aircraft during ascent to the initial drop point; desaturation; use of individual breathing apparatus when preparing to leave an aircraft; free fall from an altitude of 8 and 10 km to 3-2 km (approximately 4 minutes); descent with an open parachute; landing in a confined area, taking into account temperatures, wind speed, and direction during ejection and landing in a confined area. Analysis of the obtained data indicates a risk of autonomic dysfunction of the cardiovascular system. The desaturation data showed that the heart’s rhythm is more controlled by the body, which is common in cases of severe stress and tiredness. Researchers also found a significant positive correlation between MxDMn ms and spectral power. This finding indicated decreased resistance to high-altitude hypoxia and desaturation, which considered an internal dyschronism, a sign of premorbid conditions.

Because of the development of Arctic latitudes, there is a high probability of emergency deployment of specialists in the event of man-made disasters at critical structures, as well as the provision of medical assistance. Therefore, it is necessary to train specialists capable of providing assistance in emergency situations.
