ASSESSMENT OF GENDER AND BMI DIFFERENCES ON HEART RATE AND SYSTOLIC BLOOD PRESSURE IN YOUNG HEALTHY ADULTS AFTER ENDURANCE EXERCISE TRAINING

 Introduction: Cardiac automaticity is intrinsic to various pace maker tissue, which are largely under control of autonomic nervous system, the heart rate in the normal healthy individual represents the net effect of cardiac sympathetic and parasympathetic nervous system on myocardial activity. Methods: The present study aims to examine and analyse the pattern of blood pressure (BP) and heart rate (HR) before and after endurance exercise training on the Bicycle ergometer, in healthy young adults (50 males, 50 females). An attempt has been made to assess the effect of endurance exercise training on systolic blood pressure (SBP) and heart rate (HR) in non-athletic young adults during the first 6 min of exercise and also its effect on gender and basal metabolic rate. A randomized crossover study over a period of 8-week period involving 100 sedentary men and women was performed; participants exercised at lower or higher intensity (50% or 70% of HR reserve) in random order, with a sedentary period in between. Training programmes were identical for both gender except for intensity, and were performed under supervision daily for 2 hr. Results: The results showed that endurance exercise training reduces SBP significantly (p<0.001) both in males and females when analysed it shows reduction in SBP at different intensity of exercise but BMI showed no significant changes. The effect of exercise training on HR showed reduction in HR significantly at rest and also reduced significantly as the intensity of exercise increases when both the gender taken tougher(P<0.001), when we compared males and females separately no significant decrease was seen in case of HR. conclusion: Endurance exercise training, significantly decreases the systolic blood pressure and heart rate, which tells the improvement of the parasympathetic activity which in turn helps our understanding of the development of cardio vascular disease (CVD).
