Bernard Courtois discovered iodine in 1811 while digesting algae, which resulted in the emission of purple vapor. Bernard Courtois identified iodine within the thyroid gland in 1895 and established in 1917 that iodine deficiency leads to thyroid gland enlargement. The kidneys eliminate over 90% of iodine. The study of iodine levels in twenty-four-hour urine, measured in µg per day, is acknowledged as an optimal approach for assessing the body’s iodine status. This study aimed to investigate the dietary consumption of iodine and the urinary iodine content in young individuals. The study aimed to explore the correlation between urinary iodine content, muscle mass, and the speed of muscular response. Seventy participants aged 18 to 24 were involved, comprising 35 males and 35 females. The exclusion criteria included confirmed thyroid illness and disorders of iodine metabolism. The morning urine was tested, dietary iodine intake was evaluated, and muscle mass and response time were measured. The median iodine concentration in urine was 120.77 μg/l, and the estimated iodine consumption was 624.66 μg. The median muscle tissue percentage is 32.55%, while the median muscle reaction speed is 274.5 ms. The correlation between urinary iodine levels, muscle tissue (%), and muscle reaction speed was assessed. A notable, negative, and modest association between urinary iodine content and muscle reaction speed was identified (Rho = -0.289). Other relationships lack significance. The projected dietary iodine consumption of participants in this study exceeds the reference values established by the World Health Organization. The iodine concentration in the urine of the individuals participating in this study is within the reference levels. There is no correlation between the iodine concentration in urine and muscle mass among the studied population. The iodine concentration in urine within the studied population exhibits a substantial, negative, and modest correlation with reaction speed.

Key Words: iodine, muscles, time reactions.
