The purpose of the study was to compare the peak flow rate and body mass index between physical education and non-physical education students. To achieve the objectives of the study, a total of 100 students; fifty male and female physical education students and fifty male and female non-physical education students were selected randomly as subjects. The age of the subjects ranged between 20 to 26 years. To determine the significant difference between the mean scores of male and female physical education and non-physical education students on peak flow rate and body mass index (BMI),'t' test was applied with the help of SPSS software. The level of significance was set at 0.05. Significant difference was obtained on peak flow rate between female physical education and non-physical education students. No significant difference was obtained on body mass index (BMI) between physical education and non-physical education students. The finding reveals that female physical education students have significantly better in peak flow rate as compare to female non-physical education students.
