Objectives. To compare the effect of exergaming versus aerobic exercise on natural killer (NK) cells in normal weight and obese children. Methods. Sixty children of both sexes were divided into four equal groups: exergaming normal weight group (A), exergaming obese group (B), aerobic normal weight group (C), and aerobic obese group (D). Both (A) & (B) groups played exergaming on Nintendo Wii. (C) & (D) groups performed moderate aerobic exercise. All groups practiced 3 sessions per week, for 4 weeks. The NK cell count and its subsets (CD56dim and CD56bright) in blood were evaluated pre- and post-exergame and aerobic exercise practice. Results. Wilcoxon test and Kruskal-Wallis test revealed that the NK cell count and CD56dim showed significant reductions within group (B) (p < 0.05), while they showed significant increases within group (D) post-treatment compared to pre-treatment(p < 0.05). However, CD56bright showed significant reductions within the four groups post-treatment compared to pre-treatment (p < 0.05). Between group comparison, pre- and post-treatment, revealed non-significant differences in NK cell count and its subsets (CD56dim and CD56bright) (p > 0.05). Conclusions. Exergaming has a significant suppressive effect in obese and not in normal weight children, while aerobic exercise has a significant boosting effect in obese and not in normal weight children. However, there were no significant differences between exergaming and aerobic exercise in NK cell count in normal weight and obese children. Exergaming may be considered a novel tool for a more active and healthy lifestyle, but it may not exert the same as more as traditional physical activity.
