Abstract

Abstract : Objective: Exaggerated blood pressure (BP) response during exercise is associated with increased risk of worsening hypertension in normotensives, as well as in athletes with high normal blood pressure. To date, conflicting data have been reported concerning the nature (physiologic versus pathologic) remodeling in athletes. Data regarding preadolescents are limited.. Objective: The aim of the study was to evaluate the influence of the rest and maximal exercise BP values to the cardiac dimensions in professional elite young preadolescent footballers. Design and method: Ninety-four highly trained male footballers (mean aged 12.85 ± 0.84) competing in our Football League (at least 7 training hours/week) and 47 age-matched healthy male controls were enrolled in the study. They were screened by ECG and echocardiography at a tertiary referral cardio centre. The control group had sedentary life style (less than 2 training hours/week). Echocardiographic parameters were obtained by standard measurements. Results: All participants had normal blood pressure (BP). Mean BP in footballers was 109.95+/-65.75 and mean BP in controls was 108.19+/-60.75. There was no difference in SDP between these two groups (p > 0.05), but footballers had significantly higher values of the DBP (p < 0.01). The data indicate significant increases in absolute values of LV dimensions, but especially in the dimensions of the aortic root size (p < 0.001) in preadolescent professional footballers compared with the values expected for age-matched controls, whereas there are no differences in absolute values of ventricular septal and posterior wall thickness, LV wall thickness and LVM (p > 0.05). However, regarding aortic root dimensions there is a significant difference even in absolute values. (p < 0.001). No significant correlations between LVMI and rest values of BP were detected. Dimensions of the left atrium and aortic root however significantly correlated with SBP and DBP (p < 0.01). However, significant correlations were described between LVMI and maximal systolic BP (p < 0.01) as well as diastolic BP (p = 0.047). Conclusions: Elite preadolescent footballers had significantly higher DBP compared to sedentary controls. Left atrial and aortic root dimensions correlate with resting SBP as well as DBP, while LWMI correlates with maximal SDP and maximal DBP.
