Cardiovascular disease (CVD) is associated with the development of atherosclerotic process that begins in the arteries, representing vascular pathology, can be measured in the form of reflection index (vascular tone) and other non invasive cardiovascular parameters, leads to cardiovascular morbidity and mortality. Previous reports have described significant reduction on arterial stiffness and alteration on other related cardiovascular parameters in atheletes as well as in proficient individuals. No report so far is available on comparative analysis of non invasive vascular parameters such as reflection index (vascular tone)termed as RI, Large artery stiffness index (SI), Dicrotic index (DI), Heart rate (HR), and cardiac parameters such as Left Ventricular ejection time (LEVT), Diastolic time, Ejection slope, dp/dt max in proficient and non proficient healthy subjects. The present study has been undertaken to analyze the differences of non - invasive cardiovascular responses in both proficient and non proficient healthy subjects. Various non invasive cardiovascular parameters like RI, SI, DI, dp/dt max, LVET, pulse duration, diastolic time, ejection slope and also systolic, diastolic, mean and pulse pressure were studied by using PC based PPG analysis system. In the present study no statistical significant differences were found on body weight and age, dp/dt max and ejection slope. in two groups (proficient and non proficient), but statistical significant differences were found on RI,SI, pulse duration, diastolic time, systolic (SBP), diastolic (DBP), Pulse (PP) and mean (MABP) pressure that would be attributed to increased parasympathetic tone in proficient as compared to non proficient subjects.
