Comparative Effect of Different Intensity of Physical Fitness Exercises on Resting Respiratory Rate of Selected Age Groups

Introduction:-The purpose of the study was to investigate which type of training intensity (Low, Medium, & High) was most effective for improving resting respiratory rate of 12 weeks physical fitness exercises programme for female children age groups of 10-12years and 13-15years. Methods:- Sixty subjects were randomly selected for this research work from Govt. schools of Chandigarh, U.T. In both the age group of 10-12 years and 13-15 years, four groups 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 Resting Respiratory Rate 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 Resting Respiratory Rate of 10-12 years &13-15years female subjects, ANCOVA was used. The level of significance was set at 0.05. Result & Discussion:- There was significance difference found in Resting Respiratory Rate in both the age groups i.e. 10-12 & 13-15 years of female. Concussion: - 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 Resting Respiratory Rate of 10-12 & 13-15 years of female.
