Abstract

Objective :Maximal Expiratory Pressure (MEP) is a powerful indicator for respiratory muscle strength, which reflects the ability of a person to cough effectively.Methods: The present study was designed on healthy respiratory symptom free children of a Residential – Sainik (50) and Non-Residential (44) school children (aged 12-14 yrs) of Bijapur, to evaluate MEP in relation to their physical anthropometry. MEP (mm Hg) was determined by using a modified Black’s apparatus, which is significantly higher in Residential-Sainik school children in comparison to Non-Residential school children (p<0.01).Results: In both groups, MEP showed positive correlation with height (Residential, r=0.72, p<0.001; Non-Residential, r=0.73, p<0.001); weight (Residential, r=0.73, p<0.001; Non-Residential, r=0.69, p<0.001), BSA (Residential, r=0.79, p<0.001; Non-Residential, r=0.72, p<0.001) and BMI (Residential, r = 0.48, p<0.01; Non-Residential,r=0.34, p<0.05), and also revealed a higher MEP in children with greater chest expansion.Conclusion: Possibly, routine physical exercise in residential Sainik school children attribute to their better respiratory muscle strength.
