Abstract: Studying relationship between the impact of competition load in the work of endocrine glands is to somewhat new recent and largely correlated with major developments in sport biology and physiology science. It is well known that physical effort affects activity of many glands and hormone production rates like thyroid gland which secretes thyroxine hormone (T4) and thyronine (T3), which rotate in free form (FREE (F)) or united in blood. It is known that it affects the overall organization of metabolism, growth and tissue contrast as well as gene expression. Thyroid hormone increases metabolic actions in almost each tissue; it also increases the size and number of mitochondria in cells and its effectiveness, this in turn increase speed of triphosphate adenosine (ATP) formation to feed cellular energy with fuel needed for effort to be done for individual, especially athlete who needs great energy in depending on each requirements according to regulations in force. Although thyroid hormone is vital to many physiological system; but biological effects of short-term changes in thyroid hormone levels resulting from physical effort not fully explained yet. From what mentioned above the great importance of these hormones is clear, where correlation between competition load and these hormones not precisely specified, especially these hormones play great role in the metabolism which prompted researchers to conduct such a study and its importance to find the relationship between concentration level of thyroid hormones: associated and free T3 & T4 and adrenal cortisol hormone CO and pituitary hormone: thyrotropin TSH in blood plasma according to competition load within track racers (100m, 400m, 1500m, 5000m) hoping to present results probably will contribute to shed light in this field. Researchers used experimental approach with pre and post measurement for its relevance to research nature. Research sample included 24 male runners, their age between 20 to 29 years old were selected from first-class runners in Western Region represented for short-distance distance runners (100, 400 m), average-distance runners (1500 m), long-distance runners (5000 m). Statistical work done using SPSS program and includes (Mean-Standard deviation-Skewness–Kurtosis-Simple correlation). Most important results were that there were statistically significant correlation between competition load and changes in associated and free thyroid hormones (T3 & T4), Cortisol, thyrotropin TSH in blood plasma in (100 m, 400 m, 1500m 5000 m) in pre and most measurements, there were statistically significant correlation between competition load and changes in associated and free thyroid hormones (T3 & T4), Cortisol, thyrotropin TSH in blood plasma in (100 m, 400 m, 1500m 5000 m) between pres and post-measurements (immediately after competition), most important recommendation were necessity to give concern to nature of relations between activity of associated and free thyroid hormones T3, and T4 and cortisol CO and hormone thyrotropin TSH accordance to competition load, necessity to focus on training methods according to energy production, which in turn improves thyroid, and adrenal hormones (energy hormones) and pituitary gland hormone.
