Abstract
Objectives: The aim of this study was to investigate the effects of 8-week endurance and resistance exercise training on release of brain natriuretic peptide. Materials and Methods: Study population was categorized into 4 groups: Group-1 (n = 6) consisted of sedentary individuals who volunteered to complete 8-weeks of endurance exercise; Group-2 (n=6) consisted of sedentary individuals who volunteered to complete 8-weaks of resistance exercise. Three blood samples [for Terminal pro BNP (NT-Pro-BNP)] were taken before, immediately after exercise and after 8 weeks of exercise training. Results: NT-Pro BNP was significantly increased immediately after endurance exercise [from 37.9 ± 1.4 pg/ml to 52.1 ± 1.5 pg/ml; P = 0.002] and was decreasedto 23.2 ± 9.3 pg/ml after 8 weeks of endurance exercise [P = 0.013]. On the other hand, NT-Pro BNP showed no significant changes immediately after resistance exercise [from 26.6 ± 4.9 pg/ml to 24.1 ± 4.5 pg/ml; P = 0.553]. Incontrast, NT-Pro BNP was significantly increased to 39.5 ± 1.6 pg/ml after 8 weeks of resistance exercise [P = 0.012]. Conclusion: Endurance exercise training reduces circulating NT-Pro BNP concentration, which is likely a marker of reduced ventricular wall tension and improved myocardial function. In contrast, strength exercise induces significant increase in NT-Pro BNP, which could be partially attributed to myocardial damage.
