"Serum concentration of nitric oxide in high intensity group was significantly higher after four weeks of exercise (p =0/004) and when compared with moderate intensity group (p =0/004). concentration of Nitric oxide (NO) in three times : in fasting blood , after one onset and after four weeks in moderate and high intensity(0<05). They declared that augmented oxidative stress in high intensity cause insignificant change in NO synthesis, although oxidize LDL in which one of the main component of oxidative stress and indicate can cause Dysfunction in NO formation and inactive NO production indirectly was insignificant in their study. It seems that exercise program with high intensity lead to different tension of shear stress on blood vessel wall and create different molecular responds . ‟ Acute moderate-intensity exercise induces vasodilation through an increase in nitric oxide bioavailiability in humans". ‟ Effect of Different Intensities of Exercise on Endothelium-Dependent Vasodilation in Humans Role of Endothelium-Dependent Nitric Oxide and Oxidative Stress"."

INTRODUCTION

Endothelial cells release chemical mediator that cause vasodilation and vasoconstriction (Libis,

2005). Endothelium‌ derived‌ NO is produced by the endothelial nitric oxide synthase (eNOS).This enzyme synthesis NO from L-arginine. Nitric oxide (NO) the most potent vasodilator release from endothelium. NO immediately propagated from‌ endothelium‌ into smooth muscle cells and cause muscle relaxation. Obesity has an important role in Atherosclerosis, by decreasing in NO bioavailability (Williams et al. 2002).Watts et al. (2004) indicate‌ in‌ their study that flow mediated – dilation in obese adolescence (14.3±1.5), after eight weeks of circuit training significantly increased when compared to control group(5.3 _ 0.9% to 8.8 _ 0.8%, p _ 0.05). This augment accompanied by‌ NO‌ production‌. In this surveys on obese‌ people‌ had‌ lesser intention to different exercise intensities so the aim of this study is examine different intensities in obese and the effect‌ of‌ these‌ intensities on NO production.
