Many studies documented the relationship between elevated plasma concentrations of natriuretic peptides and cardiovascular diseases, especially heart failure. However, it is still uncertain whether physical exercise leads to a significant release of natriuretic peptide in healthy subjects. The aim of this study was to determine the effect of maximal physical activity on plasma BNP concentrations in healthy individuals within 3 hours after the short-term exercise. BNP plasma concentrations were measured in 15 healthy volunteers before, immediately after as well as 1 hour and 3 hours after bicycle spiroergometry. Maximal workload and exercise capacity were assessed in watts, watt-seconds, metabolic equivalents and VO(2max). Mean BNP plasma levels before, immediately after, 1 hour and 3 hours post-exercise were 19.4+/-2.5; 30.6+/-4.7; 17.9+/-2.5 and 18.7+/-3.1 pg/ml, respectively. The increase of BNP concentrations immediately after exercise was statistically significant (p=0.0017) compared to baseline values. We did not find any correlation between the post-exercise increase of BNP levels and age, body mass index, maximal workload or exercise capacity. In conclusion, short-term maximal physical exercise in healthy individuals led to a fast and transient rise of plasma BNP concentrations, which remained well within normal range and far below the cut-off value for heart failure (100 pg/ml).
