Abstract
: to assess the effects of aerobic exercises on immunoglobulin G, C-reactive protein, body mass index and waist circumference in obese adolescent girls. Methods: Sixty obese adolescent girls were selected from National Nutrition Institute aged from 12 to 18 years old. All girls were randomly assigned into two groups using sealed envelopes. Control group included 30 girls who received diet control therapy only. Study group included 30 girls who received aerobic exercise in the form of treadmill gait training (3 session /per week for 12 weeks) in addition to same diet control therapy. All girls in both groups were assessed before and after three successive months as Immunoglobulin G and C-Reactive Protein were measured using blood analysis, Body Mass Index calculated by weight in kilograms (Kg) divided by the girls’ height in meter squared (m2) while waist circumference by Graduated measuring tape. Results: there was a statistically significant increase in Ig immunoglobulin G level in both groups and statistically significant decrease in C-reactive protein, body mass index and waist circumference in both groups but there is no statistically significant difference in all measured variables when comparing post-treatment results of both groups. There was no significant correlation between Immunoglobulin G and all measured variables including body mass index and waist circumference in both groups. While C-Reactive Protein show moderate positive correlation with body mass index, and no significant correlation with waist circumference in the control group and strong positive correlation with both body mass index and waist circumference in the study group. Conclusion: Treadmill gait training is an effective modality that can be used in the rehabilitation program of obese adolescents to improve their immune functions and reduce inflammatory reactions.
