Characterization of the latent periods of excitation and shortening of anterior tibial muscle of white rats depending on the blood level of triiodothyronine

In experiments in situ it was shown an expressed negative correlation between the duration of latent periods of excitation and contraction of the anterior tibial muscle of white rats and the blood level of free triiodothyronine. The difference in mean values of latent periods at starting and final points of scale of physiological fluctuations of triiodothyronine level amounted 15,5% and 37,0% respectively. In parallel with lengthening of latent period of anterior tibial muscle excitation it was found an increase in latent period of this muscle contraction. Inter­estingly, at high values of the latent periods of excitation such dependence disappeared.

Keywords: muscle contraction, level of triiodothyronine.
