ABSTRACT
The iodination degree of the thyroid gland colloid of male dogs that underwent the regimen of multiple physical loads (PL) was estimated by authors by visualization of SH and SS groups by dioxydinaphtildisulphyde (DDD). The quantitative analysis of the iodination degree in the different groups of animals and the analysis of the spatial organization of the section (the central and peripheral zones) does not indicate reliable differences between them. TLPs, influencing the whole organism leads to the increase of the concentration of iodine in TG of animals, the function of the heart and respiratory system, the effective consummation of the peak of efficiency. The average optic density is a marker allowing to forecast the changes of TG in response to multiple PL.
