Abstract

Introduction: The reduction of melatonin is associated with the increase in vasoconstriction and blood pressure(BP).The purpose of this study was to investigate the effect of short-term melatonin consumption (MC) on some cardiacparameters of young women during rest,immediately after exercise and during recovery. Materials and Methods: This semi-experimental study was done in Mashhad. Active young women (24people) voluntarily participated in the study,and were randomly divided into two groups of MC and placebo groups.During rest condition,BP and body temperature were measured and heart contractility and hemodynamic parameters were measured using the cardio screen system. Then Bruce protocol was conducted on the treadmill until exhaustion phase. In the recovery,the subjects walked on the treadmill and at the fifth minute cardio-screen indicators and blood pressure were recorded. For one week,experimental group took 3milligram melatonin tablets and placebo group took 3milligram of placebo tablets every night. On the ninth day of luteinizing,the tests were repeated again and by using paired t-test and ANOVA test the following findings were obtained (p<0.05). Results: There were a significant difference(SiDi)between two groups in BP changes in the
