Effects of aerobic activity on serum IgG concentration in male physical education students

The aim of this study was to investigate the effects of aerobic activity on Serum IgG concentration. Consequently, 10 male physical education students with age ranging from 21 to 24 years old and mean body mass index 22.22 kg m2 volunteered to participate in this study. Aerobic activity was performed on bicycle ergometer for 30 minutes at intensity of 70 to 75 percent of maximum heart rate. Blood samples were obtained from subjects before and after aerobic activity. Changes in serum IgG concentration in pre-test and post-test were analyzed by dependent t-test using spss software. The results showed that aerobic activity not significantly effect on Serum IgG concentration (p=0.357). This study concludes that sub maximal aerobic activity does not affect on serum IgG concentration and there is no concern for athletes and coaches that sub maximal aerobic activity can impair immune function.
