THE MORPHO-FUNCTIONAL CHARACTERISTICS OF THE RIGHT HEART IN ELITE SERBIAN TRIATHLETES

Many research papers show that the most intense cardiac remodelling can be seen in endurance athletes, but no studies have examined right heart remodelling in triathletes. The aim of the study is to examine the morphological and functional characteristics of the right heart in elite Serbian triathletes. To assess the morphofunctional characteristics of the right heart, cardiac ultrasounds were performed following current recommendations, using a Philips IE33 device and a 5.2-MHz probe. The right ventricular diameter (RVEDD) was measured from the parasternal crosssection, and the right atrial volume (RAvol) and the right ventricular wall thickness (RVWT) were measured from the four-cavity cross-section. The M-mode method was used to measure the amplitude of the movement of the right ventricular tricuspid annulus (TAPSE). The sample consisted of two groups of men: experimental – elite triathlete seniors from Serbia (n=17; age: 35.88±11.27), and control – healthy untrained adults (n=20; age: 21.35±2.08). RVEDD, RAvol, and RVWT were significantly higher in the experimental group compared to the control group (p
