36 - EFFORT INTOLERANCE IN SUBCLINICAL HYPOTHYROIDISM: IMPLICATIONS IN PHYSICAL TRAINING PRESCRIPTION ABSTRACT

Abstract

The subclinical hypothyroidism (SH) is characterized by cardiovascular and metabolic alterations that compromise the capacity of exercise accomplishment. The intolerance to the effort is the main characteristic of these patients. Studies disclose that the hormonal replacement with levothyroxine (L-T4) revert these alterations, but the evidences are insufficient in relation to the improvement of the functional capacity. In general, patients with low tolerance to the effort present a slower response during the exercise and recovery. The present study examines the main cardiovascular alterations decurrent of the SH and its implication in the functional capacity, providing directions for future research. There is a lack of studies on the response to the exercise in these patients. Thus research is necessary that can give support to the physical exercise prescription for patients with SH.
