Abstract
Introduction: Peak expiratory flow rate is the maximum rate at which the air can be expired after deep inspiration and it is an effort dependent parameter. PEFR is measured to detect the cardiorespiratory efficiency of an individual and it is also affected by BMI of an individual. By taking appropriate measures like physical activity we can reduce the negative effect of BMI on cardiorespiratory function.
Aims and Objectives: the present study was done to see the effect of BMI on PEFR and also to compare the PEFR between boys and girls.
Materials and Methods: In the present study 300 school going children were selected and their PEFR was measured with the help of mini peak flow meter and their BMI was also calculated.
Result: the present study showed that in case of girls PEFR increased with increase in BMI but there was slight decrease in 19-22.99 categories and in case of boys the PEFR increased with correspondence with BMI but there was decrease in PEFR in 23-26.99 category.
Conclusion: from the present study we had found that BMI had a great effect on PEFR. So early physical activity will decrease BMI and thus improve one’s cardiorespiratory fitness.
