The effect of continuous and interval cardiac rehabilitation training on homocysteine, serum Atrial natriuretic peptide and functional capacity in coronary artery bypass graft patients

The purpose of this study was to investigate on the effect of continuous and interval cardiac rehabilitation training on functional capacity homocysteine and Atrial natriuretic peptide (ANP) in Coronary artery bypass surgery patient.

According to the aim of the study, 30 patients with inclusion criteria were selected and divided into three groups: continuous and interval training and control group. Individuals were trained for 8 weeks according to their special program. Before and after training protocol, blood sampling was used to measure homocysteine and ANP and functional capacity was assessed. To analyze the data, mixed design analysis of variance was used and when differences was significant Bonferroni post hoc test was used to determine the place of difference. All statistical analyzes were performed using SPSS software version 20.

Serum homocysteine decreased significantly after 8 weeks of training in both experimental groups, this decline was higher in interval training group than continuous training group (p <0.05). The intervention of continuous and interval exercises significantly reduced the level of serum ANP and improved functional capacity in experimental groups, which interval group experienced more improvement of functional capacity than continuation training group (p <0.05).

In this study, it was observed that interval training could increase functional capacity and cause to decrease the inflammatory factors, thereby preventing further complications in these patients like heart attacks.
