Abstract
The changes in plasma concentrations of TSH and thyroid hormones (L-T3 and L-T4), lactate, proteins and FFA were studied in 8 male volunteers and 8 handball players undergoing maximal exercise during 12 min on the bicycle ergometer from 1 W to 4 W/kg. Serial blood samples were taken at - 30, 0, 3, 6, 9, 12, +3, +15 and +30 min intervals. All collected samples of TSH, L-T3 and L-T4 were measured by radioimmunoassay. The possibility of interference by RAI determination, with proteins and FFA, has been studied also. In this study the available evidence suggest that proteins and FFA do not play a role of interference in the determination methodology of thyroid hormone levels. The results show correlation with haematocrit values. This interpretation is in accordance with the fact that in men, plasma concentrations of thyroid hormones are related to changes in plasmatic volume, the intensity and the extended duration of exercise.
