Abstract
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. 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. 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). Regular moderate aerobic training seems to improve immunity compared with resisted training in obese women.
Highlights
As one or more of the immune system components are inactive, immunodeficiency occurs
The capability of the immune system to respond to pathogens is reduced in both young and elderly, with immune responses starting to decrease at the age of around 50 years in obese women due to immunosenescence [1]
Participants in group A adhered to a 12-week moderate-intensity aerobic training program, whereas participants in group B adhered to a 12-week moderate-intensity resistive training program
Summary
As one or more of the immune system components are inactive, immunodeficiency occurs. The impaired immune response in obese host leads to an increased susceptibility to infection with various pathogens as influenza, community-acquired tuberculosis, Mycobacterium tuberculosis, Helicobacter pylori, coxsackie virus, and encephalomyocarditis virus. This immune response may be attributed to increased inflammation, impaired adipokine signaling, different metabolic changes, and regulation of epigenetic [12]. IgG antibodies have a big role in attacking viral and bacterial infections. They are the only type of antibody that can pass the placenta in a pregnancy and help protect the fetus [13]. Blood sampling was carried out for immunoglobulin (Ig) M and IgG in the pretest and after the 12th week of training
