Seventeen chemical warfare veterans with a disability rating of 25-35% were selected through purposive and convenience sampling methods and randomly divided into two groups: experimental (10 participants) and control (7 participants). The experimental group underwent an interval aerobic exercise regimen at 45-60% of heart rate reserve, three times per week for eight weeks. Lung functions were assessed using the Lung Test 1000 spirometry device. Repeated measures statistics analyzed the differences between pre-test and post-test results. </span></span></span></span></span><br> <span style="font-size:11pt"><span style="line-height:normal"><span style="font-family:Calibri,sans-serif"><b><span style="font-size:10.0pt"><span cambria="" style="font-family:"><span style="color:#f79646">Findings:</span></span></span></b> <span style="font-size:10.0pt"><span cambria="" style="font-family:">Aerobic exercise significantly increased vital capacity (p=0.007), peak inspiratory flow (p<0.001), peak expiratory flow (p=0.016), forced expiratory volume in 1 second (p=0.017), maximum voluntary ventilation (p<0.001), and peak expiratory flow rates at 75% (p<0.001), 50% (p=0.001), and 25% (p=0.007).
