Abstract

Background: It is well known that continuos and vigorous physical activity produce cardiac adaptations. Aim of our study was to assess the normal values of left ventricular (LV) remodeling, as assessed by three-dimensional echocardiography (3DE) in group of endurance athletes (EA), strength athletes (SA) and control. SA were athletes from Canarian wrestling, originally from Canary Islands and similar to Greco-Roman wrestling.Methods: A population of 52 athletes (25 EA and 27 SA) and 16 sedentary controls, all of them males, underwent 3DE for assessment of LV end-diastolic volume (EDV), systolic volume (ESV), mass (LVM), which were normalized to body surface area, and ejection fraction (EF). Echocardiography was performed with Philips IE33 and off line analysis with Q-Lab software.Results: General data in table 1. EDV was larger in EA engaged in SA (70±6 ml/m2 vs 57.4±8.4 ml/m2; p<0.001) and controls (53.3±8.4 ml/m2; p<0.001). Also, ESV was larger in EA vs SA (25.6±6.3 ml/m2 vs 21.3±3.2 ml/m2 respectively; p=0.014) and versus control (20,1±5,1 ml/m2; p=0.014). However, there were no statistics differences between SA and control in EDV and ESV. LVM was significantly greater in EA (112.4±22.5 g/m2; p<0.001), compared to SA (96.9±12.4 g/m2; p=0.006) and controls (81.9±15.3 g/m2; p<0.001). Too, there were differences in LVM between SA and controls (p=0.029). No significant differences were identified for EF between EA (64.2±5.6%), SA (62.5±4.7%) and controls (62.3±5.5%).Conclusion: This is the first study that analyzes cardiac adaptations of Canarian Wrestling Athletes (SA). In our study EA showed greater LV remodeling as assessed by 3D in EDV, ESV and LVM than SA and controls. However, the systolic function remained within normal limits in all athletes and controls.
