A new indicator to evaluate the Heart Rate Resilience males and females using the analysis heart rate of Complement Plots during the physical activity

Physical activity and cardiac function are interrelated in sports physiology and affects to behavioral dynamics of the heart rate. Also Heart rate analysis is a marker associated with heart modulation and Heart Rate Resilience. This study aims to present a new method and geometric index for measuring and analyzing cardiac resilience in sports activity, which is based on complement plots and Biomedical engineering technics. The novelty of this study is the type of signal recording protocol and the simultaneous use of qualitative and quantitative signal features.Our statistical population includes ۶۰ students (۴۰ men and ۲۰ women) of Imam Reza International University that were selected voluntarily. Then, we implemented & quot;۵۴۰ meters running& quot; test from them. Each person s heart rate signal was recorded with a Polar heart rate sensor and then the resilience rate of the heart was calculated using a geometric and chaotic method.Findings show that, male athletes have better heart resilience than normal men and women (P≤۰.۰۵). This means that if the resilience rate (RHR) is higher than the overall average, people will be better prepared. Based on the results, it seems that heart rate resilience analysis is a useful way to measure the level of cardiac fitness of individuals and athletes.This study is the way for strengthen the link between physical education science and biomedical engineering. Quantitative analysis alongside geometric analysis of Heart rate signals in the phase space of complement plots and mandala patterns can provide a new indicator about the analysis of the equilibrium state between sympathetic and parasympathetic nerves. However, for increase and improve the resilience of athletes hearts, other tests should be used in addition to the & quot;۵۴۰-meter run& quot; test, and all training characteristics and psychological factors of individuals should be considered.
