COMPARISON OF LEFT VENTRICULAR ECHOCARDIOGRAPHIC PROFILE OF IRANIAN ELITE WEIGHTLIFTERS WITH NONATHLETES

The aim of this study was to compare the echocardiographic profile of Iranian
elite weightlifters with non-athletes.
Materials & Methods: Subjects of the research included 10 elite weightlifters with the mean age of
21.1±2.8 years and 10 non-athletes with the mean age of 19.1±3.8 years. The subjects were tested by
one and two-dimensional echocardiography to determine cardiac structure (left ventricular mass
(TLVM), left ventricular end-diastolic diameter (LVDD), left ventricular end-systolic diameter (LVSD),
end-diastolic inter ventricular septal size (DVS), end-systolic inter ventricular septal size (SVSS)) after
completion of the consent forms and medical history questionnaires. All data were recorded digitally
according to basic data analysis calculated by two expert echo cardiographers. The data were analyzed
by independent sample t-test.
Results: Results show that the mean left ventricular structural variables of the elite weightlifters were
more than non-athletes. Except in left ventricular end-diastolic and systolic size (P>0.05), there were
significant differences in other cardiac structural variables between the two groups (P< 0.05).
Conclusion: These results are consistent with the Morgan Roth hypotheses and follow the pattern of
concentric hypertrophy
