Effects of Aerobic Exercise Programme with Different Intensities on Blood Pressure and Low Density Lipoproteins

Abstract :

The purpose of the present study was to find out the effect of aerobic exercise programme with different intensities
on blood pressure and low density lipoproteins among middle aged women. For this purpose, thirty middle aged women residing at various places around Kannur Town, Kerala, were selected as subjects. The age of the subjects were ranged from 35 to 45 years. They were divided into three equal groups, each group consisted of ten subjects, in which experimental group – I underwent aerobic training (brisk walking) with low intensity, experimental group – II underwent aerobic training (brisk walking) with moderate intensity and group – III acted as control that did not participate in any special activities apart from their regular day-to-day activities. The training period for the study was five days (Monday to Friday) in a week for twelve weeks. Prior and after the experimental period, the subjects were tested on systolic and diastolic blood pressure and low density lipoprotein. Systolic and diastolic blood pressure was assessed by using sphygmomanometer. Low density lipoproteins was tested after taking 5 ml of blood samples by venous puncture method, using CHOD – PAP method recommended by Lopes –Virella et al [1977]. The Analysis of Covariance (ANCOVA) was applied to find out any significant difference between the experimental groups and control group on selected criterion variables. The result of the study shows that the brisk walking on low intensity group and brisk walking on moderate intensity group were decreased the blood pressure and low density lipoproteins significantly. It was concluded from the results of the study that low intensity aerobic training and moderate intensity aerobic training has bring positive changes in systolic and diastolic blood pressure and low density lipoproteins as compare to the control group. Moreover it was also concluded that there was no significant difference was found between the experimental groups in all criterion variables.
