THE EFFECT OF IODINE FORTIFICATION ON THE LEVEL OF THYROXINE AND CERTAIN BIOCHEMICAL AND FUNCTIONAL VARIABLES OF VOLLEYBALL PLAYERS (YOUTH CLASS)

Abstract

Iodine is a vital and essential element involved in the production of the thyroid hormone, which is necessary for physical and mental development, as well as the development of various important body function. Therefore, iodine deficiency does not only lead to dangerous complications of the thyroid swelling, but also affects the level of intelligence and academic achievements of school children, and causes fatigue and inertia in general, preventing them from being productive or working properly. This factor hinders their development and has eventually negative influences on society both socially and economically. The problem of this research is the fact that minerals are crucial for the human body, as they perform great physiologic functions (especially for athletes). Scientific sources point out that thyroxine affects the percentage of minerals within the human body in such a way that whenever the ratio of this hormone increases, the level of minerals will increase as well. As is mentioned earlier, iodine is crucial for the activity of the thyroid gland and the secretion of thyroxine. Therefore, researchers attempted to increase the level of thyroxine secretion on a low ratio, but still within the normal limits, in order to study its influence on the level of minerals and certain functional variables of volleyball players of the youth class.
