title: [Serum concentration of T3, T4, FT3, FT4, TSH during cycloergometer muscular exercise].
abstract: The serum concentrations of total and free thyroid hormones and of TSH have been determined in 10 trained subjects before, during and after exercise on a bicycle ergometer. The concentrations of T4 and FT4 increase during the muscular exercise and reduce 30 minutes after the end of work; the decrease is statistically meaningful for the T4. The concentrations of TSH and T3 reduce 30 minutes after the end of work on a bicycle ergometer. The serum concentration of FT3 and of hematocrit doesn't presents any statistically meaningful variation during and after the muscular exercise. The results achieved in our work are in support of the hypothesis that the physic and intense exercise would involve the thyroid gland exalting its activity.
