cross-sectional study for the relationship between body composition and
body surface area with echocardiographic variables in endurance-trained
Department, Guru Nanak Dev University, Punjab, India
We ought to study the relationship between echocardiographic variables
and body composition & body surface area in endurance trained
athletes. Endurance training is associated with an increase in cardiac
structural dimensions and mass in athletes. In other populations, body
surface area was found to influence cardiac dimensions. We hypothesised
that the increase in cardiac musculature dimensions observed with
training may be a normal response to the increased training load and
increased body surface area.
Methods. Fifty male endurance athletes (cycling, N=16; long
distance running, N=22 and swimming, N=12) with eighteen male control
subjects underwent echocardiography and dual photon x-ray
absorptiometry body composition analysis. Correlation analysis was
sought for echocardiographic variables and body surface area and body
Results and conclusion. All subjects were in
the age group of 18-25 years of age. The endurance athletes had
enlarged cardiac dimensions than the control subjects (p<0.001).
Left ventricular mass, size and thickness correlated significantly with
the body surface area and lean mass but did not significantly relate to
the body fat percentage and fat mass. Lean mass was found to
be an independent predictor of left ventricular measurements.
