The heart rate deflection point (HRDP) is the heart rate deviation point of the straight line that is defined in the study of the relationship between work and time and it is used as a criterion for intensity of exercise planning. The purpose of the present study is to review the Methodological approach of heart rate deflection point the new methods for determining this point. Finally, based on the standard criteria and based titles on of the articles, only remained 16 articles based on which the study was conducted. The results of the studies indicated that in the physiological mechanisms related to HRDP, the effect of cardiac muscle, catecholamine and the nervous system, the role of potassium and Lactic acid are among the possible mechanisms involved and in Methods for determining HRDP, determining the base heart rate, methods of calculating and measuring HRDP and exercise protocols were the most important Methodological approach of this point. The results indicate that disagreement about the ability of HRDP to determine the anaerobic threshold related to the methodology of HRDP measurement. Infect, it affects the definition of the anaerobic threshold. Therefore, studies on it continue.
