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.
