The Effect of Resistance Training, Aerobic Training and Detraining on the Lipid Profile and CRP in Obese Girls

Background and Obesity is associated with various metabolic and inflammatory impairments، the effects of which have not been sufficiently studied. Therefore، the purpose of this study was to examine the influence of an 8-week strength training and aerobic training program and a 10-day detraining on lipid profile and CRP in obese girls. Methods and Materials: In this experimental study، thirty-six obese female university students were voluntarily recruited and randomly assigned into three groups: control (n=11)، aerobic training or AT (n=12) and strength training or ST (n=13). ST and AT groups trained for 8 weeks، 4 times/week، 60 min/session، with 60 to 70% of 1 repetition maximum for ST، and 65 to 75% of HRmax for AT. Blood samples were taken at baseline، 24 hours after the last exercise session and after 10 days of detraining on fasting state. Data were analyzed in SPSS 16 using repeated measure analysis of variance (RM-ANOVA). The alpha level was established at P<0. 05. After an 8-week training program، TG decreased in AT and ST groups (4. 2 % and 6. 6 %، respectively) but the change was not significant (P>0. 05). Also، no significant differences were found between the three groups (P>0. 05). TC also decreased in AT and ST groups (9% and 19%، respectively); however، the change was not significant (P>0. 05). After training no significant changes in HDL، HDL2، HDL3، LDL، and CRP were observed (P>0. 05). Ten days of detraining also did not result in any significant alterations in the lipid profile or CRP (P>0. 05). Eight weeks of aerobic and strength training have no significant effect on the lipid profile and CRP in obese girls.
