For this purpose, 12 male smokers (age: 22.08 ±1.31 years, percent of body fat: 17.26 ±4.92% and body mass index: 23.21±2.96 kg/m2) were voluntarily selected and randomly participated in a crossover design in three situations of control, exhaustive aerobic exercise at 70%-75% intensity of maximal heart rate and exhaustive aerobic exercise at 90%-95% intensity of maximal heart rate. Blood samples were collected before and immediately after the exercise. Malondialdehyde level was determined with method of ELISA. The data were analyzed using one-way ANOVA and dependent t tests. The results indicated that MDA in two experimental groups was significantly higher than the control group. Also, the comparison of the two experimental groups showed that aerobic exercise at 90%-95% intensity of maximal heart rate increased serum MDA more than aerobic exercise at 70%-75% intensity. It is suggested that smokers perform the physical activities with moderate intensity (70%-75% intensity of maximal heart rate) because oxidative stress is produced in these activities less than activities with higher intensity.
