Introduction: Adhesive molecules are cellular markers that identify the process of atherosclerotic plaque formation in the endothelial wall of arteries. The aim was evaluation of changes in E-selectin and P-selectin in men with heart failure after eight weeks of continuous and intermittent aerobic exercise.
Materials and Methods: 42 men with heart failure were selected by sampling method as volunteers and were divided into three equal groups (14 subjects) continuous aerobic, intermittent aerobic exercises and control groups. Continuous training (45-70% of Maximum Heart Rate) and intermittent training (45-80% of MHR with 5-10 minutes rest between each period) were done for 8 weeks (three days a week). Fasting blood samples were taken from all subjects before and after eight weeks of aerobic exercise and adhesion molecules were measured by ELISA method. Data were analyzed by ANCOVA at significance levels of P<0.05.
Results: Comparison of the groups with covariance analysis showed that the levels of E-selectin (P=0.002) and P-selectin (P=0.022) levels was significant in all three groups. The Bonferroni test showed, There was a significant difference between the intermittent and control (P=0.005) and between continuous and control groups (P=0.006) at the level of Eselectin and the intermittent aerobic and control groups (P=0.032) at Pselectin level, However, there was no significant change despite a decrease between the control and continuing aerobic (P=0.083) in Pselecteine. Also, there was no significant difference in the studied variables in both intermittent and continuous aerobic groups.
Conclusion: Aerobic exercise with reducing levels of adhesion molecules may play an important role in the prevention and control of cardiovascular diseases in men with heart failure.

IntroductionEvidence showed that adhesion molecules and inflammatory factors play an important role in the pathogenesis of atherosclerosis.The purpose of this study was to evaluate the effect of eight weeks of continuous and periodic aerobic exercise on the serum level of C-reactive protein and some adhesive molecules in men with heart failure. Materials and MethodsIn this study, 42 middle-aged men with heart failure were purposeful and randomly divided into three equal groups(14 subjects): continuous aerobic exercise, periodic aerobic exercise and control groups. Continuous training(45-70% of Maximum Heart Rate) and periodic exercise (45-80% of MHR with 5-10 minutes rest between each period) were done for 8 weeks(three days a week). Before and after exercise, blood samples were taken from three groups, ELISA method was used. Data were analyzed using SPSS (20 version) at a significant level of P≤0.05. ResultsAfter eight weeks of training, the level of C-reactive protein, adhesion molecule -1 and vascular adhesion molecule -1 had a significant decrease in the two training groups(P ≤ 0.05). but no significant difference was observed in the control group. There was a significant difference between the levels of hs-CRP(P = 0.023) and VCAM-1(P = 0.0001) in all three groups, but there was not a significant difference in ICAM-1 level(P = 0.17).ConclusionAerobic exercise by decreasing the levels of hs-CRP and VCAM-1 may play an important role in the prevention and control of cardiovascular disease in men with heart failure.
