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.
本研究旨在分析团体抗阻训练（伴有音乐）对肥胖女性血脂水平的影响。
样本由28名久坐不动的肥胖女性组成。其中，13人接受团体训练计划（GT）的抗阻训练，15人参加对照组（GC）。训练持续9周，每周进行三次。课程通过10项局部运动进行抗阻训练。分析评估了以下变量：两组训练前后的总胆固醇（TC）、高密度脂蛋白（HDL）、低密度脂蛋白（LDL）、甘油三酯（TG）以及TC/HDL比值。采用单因素重复测量方差分析对数据进行分析，P<0.05为有统计学意义。
研究发现，训练组除TG外，所有分析变量在训练前后均有显著差异。相比之下，对照组除TG有统计学意义的增加外，其他变量在训练前后均无显著差异。TC从200.62±39.11mg·dL-1降至184.92±28.62mg·dL-1；LDL从137.69±32.09mg·dL-1降至110.31±21.92mg·dL-1；TC/HDL比值从4.48±1.00降至3.70±0.90，HDL从46.23±12.04mg·dL-1升至53.15±16.83mg·dL-1。
因此，得出结论，伴有音乐的团体抗阻训练是有效的，因为它对血脂水平产生了有益的改变，这可能会降低肥胖女性人群患冠状动脉疾病的风险。
