Abstract

Background. In view of the continuous increase in the importance of information technologies in all spheres of society, the problem of the effect of significant cognitive loads that accompany information stress becomes extremely urgent. The article presents an analysis of studies (2018–2019) on resistance to cognitive loads in males with different levels of physical activity. Aim. The article aims to evaluate the dynamics of psychophysiological reactions to cognitive load in males with different levels of physical activity. Materials and methods. Regulatory mechanisms were assessed using the index of functional changes. The simulated load consisted in the Gorbov–Schulte table to be made in the conditions of time deficit, increased motivation and interference. Continuous recording of vascular tone, vascular blood flow, heart rate, electrical skin activity was performed. It is established that a different level of physical activity is specifically associated with the adaptation of a person to a significant cognitive load. Results. The dynamics of skin electrical activity, heart rate, vascular tone and vascular blood flow in people with moderate physical activity reflects optimal reactions to load. Conclusion. Persons systematically involved in physical activity in these conditions have a higher adaptive capacity of the vascular part in comparison with professional athletes and people not engaged in physical activity.
