METHODS: Thirty overweight women (Body mass index (BMI): 25-29.9 kg/m2) were divided, based on their BMI, into 3 groups; control, Pilates and TRX. The participants in the training groups were subjected to moderate intensity of Pilates or TRX exercise training 3 times a week for 8 weeks. Blood samples were taken at pre-test and 48 h after the last training session and used for analyzing irisin, insulin and glucose. Data were analyzed by ANCOVA and paired-samples t-test.
RESULTS: The finding showed that the Pilates training decreased body weight and BMI compared to the pre-test (P < 0.05). Also, it has been revealed that irisin concentration in response to Pilates and TRX training programs were increased in comparison with the control group (P < 0.05). However, there was no significant difference in irisin concentrations between training groups (p > 0.05). Moreover, fasting insulin, glucose and insulin resistance were significantly reduced after exercise intervention compared to the pre-test which were significantly lowered compared to the control group as well.
CONCLUSIONS: The results suggest Pilates and TRX trainings are two efficient model of exercise that by eliciting an exercise-hormone, irisin, can improve insulin resistance in overweight women.
方法:30名超重女性(体重指数(BMI):25-29.9kg/m2)根据他们的BMI,分为3组;对照,普拉提和TRX。训练组的参与者每周进行3次中等强度的普拉提或TRX运动训练,共8周。在测试前和最后一次训练后48小时采集血样,用于分析irisin,胰岛素和葡萄糖。数据通过ANCOVA和配对样本t检验进行分析。
结果:结果表明,普拉提训练与测试前相比,降低了体重和BMI(P<0.05)。此外,结果表明,与对照组相比,普拉提和TRX训练计划中的irisin浓度增加(P<0.05)。然而,两组间的irisin浓度差异无统计学意义(p>0.05)。此外,空腹胰岛素,与试验前相比,运动干预后葡萄糖和胰岛素抵抗显着降低,与对照组相比也显着降低。
结论:结果表明,普拉提和TRX训练是两种有效的运动模型,通过激发运动激素,irisin,可以改善超重女性的胰岛素抵抗。
