Comparing the acute response of ANP serum to intensive anaerobic exercise in healthy trained & untrained men

Atrial natriuretic peptide is a type of peptide hormone which release into blood in term of atrials stretch. This hormone it have beneficial effect in decrease hypertension. Physical activity may be that causes to change secretion of this hormone. The purpose of this study evaluate the effect of one session anaerobic exercise in serum ANP on trained and untrained healthy men.
Population consist of 15 trained healthy men( age: 21/6 ± 1/88 year, height: 174/33 ± 5/75 cm, weight: 67/68 ± 5/53 kg) and 15 untrained healthy men( age: 21/4 ± 2/16 year, height: 175/66 ± 4/76 cm, weight: 69/6 ± 4/61 kg). Both groups performed Rast anaerobic test. They run with maximum power 35 metric distance( 6 distance) and around 10 second rest between any distance. 10 minute before started and immediately after training, blood sample were collect to assay serum ANP. Data were analyzed by used Spss software( version 16), descriptive statistics, independent T test, correlated T test and analysis of covariance in significance level P ≤ 0/05.
The result showed that one session anaerobic training it causes significant increase of serum ANP in both groups, but in trained group was significantly higher than untrained group. Also primal content of serum ANP it were higher in trained group than untrained group.
Based on this investigate, it seem that one session of anaerobic training it able to increase of serum ANP in trained and untrained healthy men, and plays a important role in blood pressure control.
