Abstract:
The purpose of present study was to find out the effect of low and medium intensity cardiac circuit exercises on inspiratory reserve volume and expiratory reserve volume among obese male students. To achieve this purpose, forty five obese male students, studying in various classes and departments of Annamalai University, Annamalainagar, Chidambaram, Tamil Nadu, in the age group of 21 - 25 years were selected as subjects. The selected 45 subjects were divided into three equal groups, in which, group – I (n = 15) underwent low intensity cardiac circuit exercise with 50% of heart rate, group – II (n = 15) underwent medium intensity cardiac circuit exercise with 55% of heart rate, group – III (n = 15) acted as control which did not participate in any special training. The training programme was carried three days per week for twelve weeks (alternative days). Prior to and after the training period the subjects were tested for inspiratory reserve volume and expiratory reserve volume. inspiratory reserve volume and expiratory reserve volume was measured by using expirograph. The collected data were statistically analyzed by using Analysis of Covariance (ANCOVA) and Scheffĕ’s Post-Hoc Test. The result of the study was a significant improvement on inspiratory reserve volume and expiratory reserve volume after twelve weeks of low and medium intensity cardiac circuit exercises. However the increase was favour of experimental group. There was a significant difference was occurred between low, medium intensity cardiac circuit exercises and control group after twelve weeks of low and medium intensity cardiac circuit exercises.
