Purpose: We examined the effects of aerobic exercise and detraining on adiponectin, resistin, tumor necrosis factor alpha (TNF-α), white blood cell, and pubertal signs (uterine length, ovarian volume, luteinizing hormone [LH], and follicle-stimulating hormone [FSH]) in girls with central precocious puberty (CPP). Methods: Thirty girls with CPP (7–9 yr old) were randomly divided into CPP and CPP + Exercise (EX) groups. Fifteen healthy age-matched girls without precocious puberty participated for comparison with CPP. Subjects in the CPP + EX group attended 12 wk of aerobic exercise protocol three sessions a week. In the baseline, after completing the exercise protocol and after 4 wk of detraining, all the parameters were measured. In the CPP and healthy groups, all the parameters were measured in all three stages. To measure adiponectin, resistin, and TNF-α, the ELISA method was used. LH and FSH were measured by electrochemiluminescence immunoassay. White blood cell counts were analyzed by an automated blood cell counter. Repeated-measures ANOVA was used to analyze the results. Results: CPP girls have lower adiponectin (P = 0.01) and higher TNF-α levels (P = 0.001) than healthy girls. In the CPP + EX group, after 12 wk, body weight and fat mass decreased, and adiponectin increased significantly (P = 0.02). Resistin (P = 0.02), TNF-α (P = 0.02), neutrophils (P = 0.01), and signs of puberty significantly (P < 0.05) decreased. After detraining, no significant change was observed except TNF-α, which increased significantly (P = 0.03). In the CPP group, no significant change was observed in any of the parameters; only LH (P = 0.0001) and uterine length and ovarian volume (P = 0.003, P = 0.001) decreased after 12 and 16 wk, respectively. Conclusions: Aerobic exercise can have a positive effect on the state of inflammation and pubertal signs. Positive effects remain after 4 wk of detraining. [ABSTRACT FROM AUTHOR]
