Effect of Different Intensities of Aerobic Training on Cardiac Output of Middle Aged Obese Men

Abstract:

To achieve this purpose forty five (N = 45) obese men (BMI 30  1 kg/m2) from Annamalainagar, Chidambaram, Tamil Nadu, India) from the total population of (obese volunteers) 173 were selected at random subjects for this study. Their age mean height and weight were 43  2.7 years, 168  6 cm and 81  3.7 kg respectively. They were randomly divided into three equal groups, and each group consisted of fifteen (n = 15) subjects, in which, Group I underwent low intensity aerobic training, Group II underwent high intensity aerobic training and Group III acted as control. Low Intensity was Pedal at cadence of 40 revolutions per minute of bicycle ergo meter training for 5 days per week for sixteen weeks. High intensity Pedal at cadence of 60 revolutions per Minute of bicycle ergo meter training for 5 days per week for sixteen weeks. The selected criterion variable Cardiac Output to assess M-mode Doppler echocardiography and transducer was used to assess cardiac output. Pre-test data were collected two days before the training program and post-test data were collected two days after the training program. The collected data treated with ANCOVA. Level of confidence was fixed at 0.05. If obtained ‘F’ ratio significant scheffe’s post hoc test were used. The result shows that High intensity aerobic training positively influences the cardiopulmonary (Cardiac output), variable of middle-aged obese men. Low intensity aerobic training also positively influences the cardiopulmonary (Cardiac output) variable of middle-aged obese men.
