In an indoor laboratory in Прикамский, Russia, a shirtless man is actively running on a treadmill, engaged in what appears to be a physiological assessment such as a VO2 max or stress test. He wears a specialized mask over his mouth and nose, connected by tubes to monitoring equipment, along with a black heart rate monitor strap across his chest. His black running shorts display "QUART" partially visible on the side, and his sneakers feature distinctive bright green and blue soles. In the background, a woman sits at a desk, diligently observing a computer screen and writing, likely recording data or managing the test. The room is brightly lit and equipped with several computer monitors and various medical instruments. Outside a large window, an overcast sky hangs over a view of a building with a red roof, lush green trees, and a sports court with a visible basketball hoop, with indications of wet ground. The brand name "CORTEX" is visible on the console of the treadmill.
