Physical training results in favorable cardiovascular changes and that autonomic nervous system the “Prime Mediator” of there changes.
The present study was conducted to test the hypothesis that a short duration of supervised physical training may result in improved cardiovascular recovery profile in humans.
Over a two month period, 25 healthy adult female volunteers in age group of 17 to 20 years, the study was conducted in the Department of Physiology Navodaya Medical College, Raichur. Cardio vascular physical performance parameters were measured in terms of heart rate and blood pressure during physical exercise (Bicycle ergometery) as well as post exercise period.
The increase in heart at low to moderate level of exercise is due to vagal withdrawal and at severe exercise is due to sympathetic activation, in physically trained individuals less increase in heart rate during exercise could be due to autonomic modulation, blood pressure response after physical training has shown significant decrease at 4th, 5th & 6th minute after exercise, after physical training. These trends has suggested increased parasympathetic tone and decreased sympathetic tone after physical training.
It is concluded that blood pressure has shown increased reading at beginning of exercise is due to rapid vagal withdrawal and decreased reading of blood pressure after training are due to transient increase in vagal tone.
