Effects of resistance training on the lipid profile in obese women

The aim of the present study was to analyze the effects of resistance training in groups (with music) on the lipid profile in obese women.

The sample was composed of 28 sedentary obese women. Of these, 13 were submitted to the resistance training in group program (GT) and 15 took part in a control group (GC). The training lasted for 9 weeks, with three weekly sessions. The classes emphasized resistance training through the performance of 10 localized exercises. The analysis evaluated the following variables: total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG) and the TC/HDL ratio in the pre and post-training periods in both groups. The data was analyzed using Anova for repeated measures with one factor, adopting P<0.05.

The study found significant differences for the training group between the pre- and post-training period in all the analyzed variables, except for the TG. In contrast, for the control group there was no significant difference between the pre and post-training period in any of the variables, except for the TG in which we found a statistically significant increase. The reductions were from 200.62 ± 39.11 mg·dL-1 to 184.92 ± 28.62 mg·dL-1 for TC; from 137.69 ± 32.09 mg·dL-1 to 110.31 ± 21.92 mg·dL-1 for LDL; from 4.48 ± 1.00 to 3.70 ± 0.90 for the TC/HDL ratio and the improvement in the HDL was from 46.23 ± 12.04 mg·dL-1 to 53.15 ± 16.83 mg·dL-1.

Thus, it was concluded that the resistance training in groups with music was effective since it provided beneficial modifications to the lipid profile, which may result in lower risk of coronary arterial diseases in the obese female population.
