The video depicts a physiological exercise test occurring in an indoor lab setting. A shirtless man with a muscular build, wearing black athletic shorts and sneakers, is running on a "SCHILLER" brand treadmill. He has a respiratory mask covering his mouth and nose, connected to equipment off-screen, and a heart rate monitor strap across his chest, indicating that his vital signs and gas exchange are being measured. To the right of the treadmill, a "CORTEX" branded mobile cart holds a computer monitor displaying various data points and a graph, including numbers such as "160", "3.435", "38.8 46,92", "15.59 4.89", and "83.0 0.91 00:11:13", which are likely physiological metrics. A keyboard and mouse are also on the cart. Partially visible behind the treadmill, a second person, presumably a technician or observer, is seated at a desk. A large window along the back wall provides a view of an outdoor environment. The weather appears overcast, with green trees and what looks like a red running track or sports field visible. Distant buildings can also be seen. The setting suggests a sports science facility or a university lab in Прикамский, Russia. The man is running steadily, focused on the activity, while the equipment records his performance data.
