Background and objectives: The possible morphological and functional adaptation that the right ventricle (RV) suffers according to the type of sport practiced has received less attention than that one of the left ventricle. Our goal is to determine them in a group of professional athletes and compare them to healthy subjects who do not practice sports at a professional level.

Method: We performed a transthoracic echocardiogram (TTE) on runners (R), canarian wrestlers (W) and healthy controls (H). We compared the morphological and functional findings related to RV.

Results: 68 subjects (25 R, 27 W and 16 H), mean age 29 ± 4 years, mean training R and W 13.2 ± 7.3 years. Body mass index (BMI) and echocardiographic variables, according to the type of sport practiced, are shown in Table 1. In both R and W, a significant TAPSE increase was observed in relation to H. In the medium and basal diameters of the RV, once indexed by body surface (BS), a statistically significant increase in the R is observed from apical, four chambers at the end of the diastole and in the longitudinal diameter, both in relation to the W, and to the S.

Conclusions: our sample shows an increase in systolic function and RV diameters in R compared to W and in relation to H. All this seems to indicate that the adaptation of the RV varies according to the characteristics of the type of sport practiced, in relation to the controls
