Methodological approach of heart rate deflection point

Introduction 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 the 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. In the present study, the dimensions of HRDP methodology were examined in two areas of HRDP-related physiological mechanisms and HRDP determination methods. In the section on HRDP determination methods, determining the basal heart rate, HRDP calculation, and measurement methods, as well as training protocols, were the most important dimensions of methodology in measuring this point. The present study, by examining the findings of previous research, obtained a suitable and integrated summary of the physiological mechanisms associated with HRDP and the methodological dimensions of HRDP. 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
