The Effect of Rast Exercise on Plasma Levels of Apelin and Blood Pressure in Elite Women Runner

Intense exercise increases heart susceptibility to the disorder in this physiological factor.The purpose of this study is to study the effect of sprint interval training on plasma levels of apelin, blood pressure and heart rate in elite female runner. Plasma levels of apelin, Heart rate (HR) & blood pressure (BP), analyzed before, after and 24 hours after exercise. 15 elite female runner, whom were playing in Shiraz track & field league, selected for this study. They all were homogenized according to any kind of disease. Rast exercise made plasma level of Apelin decrease after exercise compared with plasma level before exercise and this decrease was significant (p=0.001). Also, plasma level of apelin increased significantly 24 hrs after finishing exercise (p=0.001), but there were no significant differences before exercise (p=0.375). Systolic blood pressure and heart rate increased immediately after exercise and decreased significantly after 24 hrs (p=0.001). However, significant difference was not observed in diastolic pressure before and after exercise (p=0.338). The finding of this study shows that sprint interval training decreases plasma levels of apelin, so we can say that apelin and blood pressure must be in balance in natural position. With knowing the role of apelin, changes in this peptide during exercise can be an alarm to cardiovascular risk factor, during or after exercise in elite athletes.
