The study of physical performance in young men living in the northern region and its assessment depending on the absence or presence of a bad habit — smoking. A total
of 50 boys aged 20 years participated in the experiment (smoking boys, n = 24; non-smoking boys, n = 26). To assess physical performance, we used load testing on a bicycle ergometer (load capacity — 1.5 kGm/min (0.25 W), pedaling frequency — 60 rpm). The cardiopulmonary MetaMax®3B system from CORTEX Biophysik GmbH was used to measure pulmonary gas exchange. The results of the study showed lower values of VO2 and VCO2 against the background of higher heart rate values in smoking young men in a state of relative muscle rest. When performing physical activity in this group, a slowdown in the processes of developing the hemodynamic system was noted against the background of an active increase in gas exchange processes. In smokers, the restoration of tissue oxygen supply (VO2) and the removal of metabolic products (VCO2) after exercising for 1 and 2 minutes is more pronounced (by 5–8 %). By the end of the recovery process (three minutes), the values of VCO2 and VT indicators in young men do not return to their initial values, remaining 11–15 % and 5–6 % higher, respectively, in smokers and non-smokers. The noted incompleteness
of the recovery processes in the respiratory system after the end of the three-minute recovery period indicates a low level of physical performance in young people, more pronounced in smokers.
