Respiratory parameters (FVC, FEV₁, FEV₁% and PEFR) were measured at rest and after step exercise. Data tables were prepared and statistical tests were carried out to test the significance.<span style="mso-spacerun:yes">&nbsp; </span><o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;text-justify:inter-ideograph;line-height:150%"><b style="mso-bidi-font-weight:&#10;normal"><u><span style="font-size:12.0pt;line-height:150%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Results:</span></u></b><span style="font-size:12.0pt;line-height:150%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;"> Post-exercise values of pulmonary function test increased significantly (p &lt; 0.01) for FVC, FEV₁ and PEFR. When these data were evaluated on the bases of body mass index the post-exercise values of FVC and PEFR were reduced than the baseline values in pre-obese (BMI 25-29.99 kg/m²) subjects. This result was found to be statistically significant (p &lt; 0.01). <o:p></o:p></span></p> <p class="MsoNormal" style="margin-bottom:0in;margin-bottom:.0001pt;text-align:&#10;justify;text-justify:inter-ideograph;line-height:150%"><b style="mso-bidi-font-weight:&#10;normal"><u><span style="font-size:12.0pt;line-height:150%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;">Conclusion:</span></u></b><span style="font-size:12.0pt;line-height:150%;font-family:&quot;Times New Roman&quot;,&quot;serif&quot;"> Considering the effect of acute exercise, respiratory parameters FVC, FEV₁ and PEFR significantly increased in males and females but in subjects with higher body mass index the values of FVC and PEFR decreased. This may be due to the increased body fat percentage imposing a mechanical restraint to the movement of abdomen and thorax and increased airway resistance in pre-obese individuals. <o:p></o:p></span></p>
