Abstract
The prevalence of obesity in children and adolescents are increasing rapidly worldwide. A rising rate of obesity in epidemic proportions also brings about economic consequences and substantial healthcare costs. Regular physical activity positively affects the blood lipid and lipoprotein profile. The scientific understanding is that physical activity or planned exercise positively alters blood triglyceride levels. The study was to find out the Comparative effect of different intensities of physical fitness exercises on muscular strength and anaerobic power among obese school boys. Only 90 obese school boys were selected randomly as subjects from the selected Schools of Thoothukudi District. To identify the obese boys, the body mass index as suggested by World Health Organization (WHO) was used. The age of the subjects was restricted into 13 to 15 years. The selected subjects were divided into two experimental groups and a control group. No step was taken to equate the group in any manner. Group I underwent moderate intensity physical fitness exercise, Group II underwent high intensity physical fitness exercise, on three alternate days in a week for a period of twelve weeks and Group III acted as Control.The dependent variables selected for this study were muscular strength and anaerobic power. All the subjects were tested prior to and immediately after the experimentation on skill performance. The collected data from the three groups prior to and immediately after the training programme on selected criterion variables were statistically analyzed with dependent ‘t’ test and analysis of covariance (ANCOVA). Whenever the ‘F’ ratio for adjusted test was found to be significant, the Scheffe’s test was applied as post-hoc test to find out paired mean difference. In all the cases 0.05 level of significant was fixed. The result of the study also revealed that there was a significant improvement on muscular strength and anaerobic power after the moderate and high intensity physical training groups and significant difference was found between the training groups on muscular strength and anaerobic power in favour of high intensity physical exercise training groups. Key Words: moderate intensity physical exercise, high intensity physical fitness exercise, Muscular Strength, Anaerobic Power and Obese.
