Abstract

Exercise training of moderate intensity provokes important adaptations and beneficial changes to cardiovascular system. On the other hand, high intensity exercise training, performed by elite athletes, leads to more extreme cardiovascular adaptations. Resting bradycardia, that is important marker of exercise training efficacy, is very pronouced in athletes and can reach 25bpm. The structural modifications are also very expressive in this population and they are knowed as athlete´s heart. However, the magnitude of these adaptations can range widely between athletes and some factors can county for this, such as: 1) the sport modality (prevalence of dynamic component - aerobic exercise; prevalence of static component - strength exercise; or both component), 2) the period of exercise training (base period or competitive period); 3) the time engajed in competitive training; 4) the gender of the athlete and 5) the athletic level (amateur ou elite). Besides the different magnitude of cardiac structural adaptation and the cardiac rhythm, the mechanisms involved to explain such adaptations are still controversial on literature. One reason for such controversy seems to be related to lack of control of these factors. Thus, we believe that one study designed to control the sport modality and training period in elite athletes could be of great interest for better understanding of the regulation and cardiovascular adaptation in this population. The findings would be usefull on clinical practice helping to distinguish between physiologic and non physiologic adaptations in this population. So, in the present project aimed to study the effect of different sports modalities (running, cycling, rowing) and the training periods (base and competitive) on hemodynamic, cardiac structural adaptations, and cardiac autonomic control in elite athletes.
