Aim: To Study the effect of front-pack and backpack weight on respiratory function in school going children in age group of 10-15 years.

Relevance of Study: There is ongoing concern regarding the weight of children's Schoolbags and negative consequences of such heavy load On developing spine and cardio-respiratory Systems. Increasing the mass of the load, thus increasing overall workload, consistently results in increased energy expenditure. So this study will help in carring out impact of Whether frontpack and backpack is more in school going children.

Methodology: In this observational study, 48 school going children were taken who carried school bags. Subjects were choosen according to inclusion and exclusion criteria. subjects willingly participated from age of 10-12 yrs with avg wt. of 5.50 and age of 13-15 yrs with avg wt. 10.80 kg has been kept in the bag. The subject first performed the procedure of PFT maneavre by without bag and rest was given for 3 min, then frontpack and rest was given for 3 min and then backpack. Thereafter the PFT parameters like FVC, FEV1 and PEFR been checked, The same procedure was repeated in all subjects.

Result: The Statistical data Analysis was done. After analysis of data using the GraphPad Instat was done and paired t-test is used to compare the difference between FVC, FEV1 and PEFR with frontpack and FVC, FEV1 and PEFR with backpack for all subjects among the 2 age groups. FVC in age 10-12 group.i.e group 1 the mean for Frontpack is [68.833] and for Backpack is [70.250] and age group 13-15,i.e group 2 the mean for frontpack is [73.73] and for backpack is [78.735]. FEV1 in age group 10-12, i.e group 1 the mean for frontpack is [75.417] and for backpack is [78.5] and age group 13-15, i.e group 2 the mean for frontpack is [78.382]and for backpack is [81.382] PEFR in age group 10-12 i.e group 1 the mean value frontpack is [60.883] and Backpack is [78.75] and age group 13-15 i.e group 2,the mean for frontpack is [75.618] and for Backpack is [82.471]. The p- value <0.0001 considered extremely significant.

Conclusion’ It is concluded that while carrying the backpack is better than carrying the frontpack, So Backpack has the advantage over the Frontpack in terms of ventilatory parameters.
