The purpose of the study was to investigate which type of training intensity (Low, Medium, & High) was most effective for improving cardio-respiratory fitness and body composition of 12 weeks physical fitness exercises programme for feminine children age groups of 13-15years. Sixty subjects were randomly selected for this research work from Govt. schools of Chandigarh, U.T. In the age group of 13-15 years A, B, C and D was made of 15 subjects each. Group A (Low Intensity), Group B (Medium Intensity) & Group C (High intensity) acted as Experimental groups, who had participated in 12 weeks physical fitness exercise programme. Whereas other fifteen subjects followed their usual programme and acted as Control Group D. To determine the characteristics of cardio-respiratory fitness and body composition, before and after 12 weeks of training at different intensity, mean and standard deviation was used. To compare adjusted post-test means of experimental groups and control group in relation to Cardio-respiratory fitness and Body Composition of 13-15 years, ANCOVA was used. The level of significance was set at 0.05. There were the significance difference found in all the variables except body composition. So, it was concluded that if exercises proposed in the present study performed at medium intensity i.e. 60-65% would be most suitable for improving Cardiorespiratory fitness of 13-15 of feminine.
