“…In the current study, LV mass of dynamic and static athletes was significantly greater than that in nonathletes. This finding was previously reported by Abinader et al26 and D’Andrea et al3 Although the current study did not result in a difference between static and dynamic athletes with regard to LV mass, Venckunas et al indicated that LV mass was lower in static athletes compared with dynamic athletes 7. During dynamic exercise, the LV withstands repetitive stress, which leads to an increase in LV mass.…”

Background:Over the last two decades, morphological cardiac changes induced by athletic conditioning have been of great interest. Therefore, several studies have been orchestrated to delineate electrocardiography (ECG), echocardiography, and heart rate variability (HRV) findings in athletes.Purpose:To assess the ECG, echocardiography, and HRV in a group of dynamic and static type athletes.Methods:Fifty professional athletes (20 static and 30 dynamic exercise athletes) and 50 healthy nonathletes (control group) were recruited. Standard 12-lead ECG and transthoracic echocardiography was performed on all athletes and the control group. Through echocardiography, variables including left ventricular (LV) end-diastolic/systolic diameter, LV mass, and left atrial volume index were measured. In addition, both the athletes and the control group underwent ECG Holter monitoring for 15 minutes and several parameters related to HRV (time and frequency domain) were recorded.Results:The most common ECG abnormalities among the athletes were sinus bradycardia and incomplete right bundle branch block. LV end-diastolic diameter and left atrial volume index were significantly greater in the dynamic athletes (P < 0.001). LV end-systolic diameter was significantly lower in the static group (P < 0.001). LV mass of the dynamic and static athletes was significantly greater than that of the controls (P < 0.001). Among the ECG Holter monitoring findings, the dynamic athletes had lower systolic blood pressure than the controls (P = 0.01). Heart rate was lowest in the control group (P < 0.001).Conclusion:The most common ECG abnormalities among adolescent Iranian athletes were sinus bradycardia and incomplete right bundle branch block. Static exercise seemed to reduce LV end-systolic diameter, while dynamic exercise resulted in increased LV end-diastolic diameter and left atrial volume index. Additionally, Iranian athletes showed no differences in HRV parameters, excluding heart rate and systolic blood pressure, compared with the nonathletes.

“…Global diastolic LV function was normal as well, which in contrary to the report on Strongmen who perform very intense resistance training and avoid aerobic training (30). Global diastolic function (assessed as E/A ratio) has been reported to be normal in female athletes from other resistance type of sports (9).…”

Introduction: Exercise training, besides many health benefits, may result in cardiac remodelling which is dependent on the type and amount of exercise performed. It is not clear, however, whether significant adaptation in cardiac structure is possible in females undergoing resistance type of exercise training. Rigorous high volume training of most muscle groups emphasising resistance exercises are being undertaken by athletes of some aesthetic sports such as female fitness (light bodybuilding). The impact of this type of training on cardiac adaptation has not been investigated until now. The aim of the current study was to disclose the effect of high volume resistance training on cardiac structure and function. Methods: 11 top-level female fitness athletes and 20 sedentary age-matched controls were recruited to undergo two-dimensional echocardiography. Results: Cardiac structure did not differ between elite female fitness athletes and controls (p > 0.05), and fitness athletes had a tendency for a smaller (p = 0.07) left ventricular (LV) mass indexed to lean body mass. Doppler diastolic function index (E/A ratio) and LV ejection fraction were similar between the groups (p > 0.05). Conclusions: Elite female fitness athletes have normal cardiac size and function that do not differ from matched sedentary controls. Consequently, as high volume resistance training has no easily observable effect on adaptation of cardiac structure, when cardiac hypertrophy is present in young resistance-trained lean female, other reasons such as inherited cardiac disease are to be considered carefully.

“…In this study 11 of 100 athlete participants show an increase in left ventricle enddiastolic dimension (<58mm). The study carried out by Venckunas detected that there is a close correlation between the increase in the size of the heart and exercise (Venckunas et al, 2011).…”

Competitor's heart is a set of constructions and physiological alteration that correlate to a long period of sport. The lack of reference to this status may lead to be classified as a disease, this study intended to evaluate morphological and functional changes in left ventricular in male athletes. One hundred and thirty-one intact participants between 15-33 years were involved in this research, 31 of them act as a control subject, echocardiographic scan was done to find left ventricular internal enddiastolic dimension, interventricular septal wall thickness, left ventricular posterior wall thickness, relative wall thickness, left ventricular mass and ejection fraction for two groups of athletes (aerobic & anaerobic) and nonsports group (control), analysis was conducted using SPSS (Statistical Package for the Social Sciences). Athlete's average parameters were higher than those of the control were; end diastolic dimension (51.5±4.8mm versus 48.0±4.4mm), interventricular septal wall thickness (9.7±1.05mm versus 8.4±0.9mm), posterior wall thickness (9.5±0.85mm versus 8.4±0.6mm), relative wall thickness (0.40 ±0.08mmversus 0.35±0.05mm), left ventricular mass (191.1±37.2g versus 141.1±36.4g) and ejection fraction (70.6±5.3 versus 66.5±4.5). There was a significant difference between athletes and the control participants concern to all measurements. Results of the study are compatible with earlier findings; this data will be benefit into medical evaluation purpose in the sporty society.
