Comparison between the effects of aerobic and resistive training on immunoglobulins in obese women

Background and purpose Obesity has adverse consequences on the immune system, causing immunosuppression, and thus increasing the incidence of infections and certain types of cancer in obese individuals. The aim of this study was to compare changes in selected immune system responses after moderate aerobic and resistive training in obese women. Methods In total, 40 obese women (age: 35–45 years) were selected and divided into two equal groups: the aerobic training group (A), in which women received moderate-intensity aerobic training; and the resistive training group (B), in which women received moderate-intensity resistive training. Blood sampling was carried out for immunoglobulin (Ig) M and IgG in the pretest and after the 12th week of training. Results There was a significant increase in IgM and IgG in response to aerobic training, whereas no significant changes occurred in the resistive training group. There were significant differences in IgM and IgG between the two groups after training in favor of the aerobic training group (A). Conclusion Regular moderate aerobic training seems to improve immunity compared with resisted training in obese women.
