Abstract
Background: Brain natriuretic peptide (BNP) reflects myocardial wall stress. BNP activities are similar to those
of atrial natriuretic peptide, including diuresis, natriuresis, hypotension and smooth muscle relaxation as well
as ability to inhibit the rennin aldosterone system. It is mainly produced and released into the circulation by
the ventricle in response to increased ventricular wall pressure or stretching. Therefore, BNP can be served as
a marker of left ventricular dysfunction. The aim of this study was to investigate effect of various professional
exercises on plasma BNP levels.
Methods: We enrolled 20 consecutive healthy professional athletic males from different sporting disciplines including
5 football players, 5 volleyball players, 5 bodybuilders and 5 water- polo players. Plasma BNP samples
were taken immediately before and 1 hour after exercise.
Results: Plasma BNP level was significantly increased after exercise (30.01 ± 23.46 vs. 16.72 ± 10.86 pg/ml;
P= 0.042). The highest increase in BNP level was found among volleyball players (mean values: 19.12 to 43.38
pg/ml; 126.3% increase after volleyball) compared to other exercises.
Conclusion: Exercise can increase plasma BNP levels, particularly among volleyball players.
