MORPHOFUNCTIONAL CONDITIONS OF THE HEART OF ATHLETICATHLETES

Abstract

Descriptive study reveals the fact that involved 20 track and field athletes aims to see the condition of
the left ventricle morphofunction exposed to heavy intensity physical exercise for several years, which
is reflected through: 1) End-diastolic diameter - EDD, 2) End-diastolic diameter - systolic diameter -
EDS, 3) Posterior wall thickness - PWT, 4) End-diastolic volume - EDV, 5) End systolic volume -
ESV, 6) Ejection Fraction - EF, 7) intraventricular septum - IVS, 8) Fractional shortening - FS along
with other variables namely: Left Ventricular Mass (LVM), Left Ventricular Mass Index (LVMI),
Body Surface Area (BSA), maximal oxygen volume (VO2 max.), Heart Rate (HR ), Stroke Volume
(SV), Cardiac Output (CO), and Blood pressure (BP). To obtain data on VO2 max. use Balke Test
which run for 15 minutes, whereas to obtain the data of left ventricle morphofunction used
Echocardiography. The data obtained were analyzed using descriptive statistics. Despite a mean value
of the morphological left ventricle of heart due to exposure to physical exercise with high intensity
which is reflected through: 1) EDD, 2) ESD, 3) PWT, 4) IVS, 5) LVN, 6) LVMI exceeding normal
values or the presence of concentric hypertrophy, but this condition is followed by an increasing
function variables that are reflected through: 1) EDV, 2) ESV, 3) EF, 4) SV, 5) FS and overall cardiac
function are reflected through the high of VO2 max., a low heart rate and the high of cardiac output. In
other words, a phenomenon found in the sample enlarged heart condition (hypertrophic) without
disproportionate septal concentric LVH but assign it to this condition in what is called by the term
“athlete's heart”, which found that the size and weight increase but remain in a physiological condition.
