The issue of the relationship between the spatiotemporal dynamics of body temperature and changes in microcirculatory perfusion during physical exertion is considered. Local temperature gradients can serve as an indirect indicator of vascular reactions, but their diagnostic potential has not been sufficiently studied.

The purpose of the work. Investigation of the spatiotemporal dynamics of body temperature during metered physical activity and during the recovery period to identify temperature patterns associated with the functional state of the cardiovascular system and tissue perfusion.

Results. The study examined the spatiotemporal dynamics of body temperature in healthy volunteers under metered-dose exercise and during the recovery period. An experimental protocol has been developed that provides for the use of a multichannel local thermometry system under conditions of a bicycle ergometric stress test, which made it possible to record temperature changes in four vascular zones of the upper limb in real time. The revealed temperature patterns reflect the reaction of the main vessels and the microcirculatory bed and can serve as a basis for the development of diagnostic criteria for assessing vascular regulation.

Practical significance. The developed protocol of multichannel local thermometry can be used for noninvasive assessment of the functional state of peripheral blood circulation under stress testing conditions.
