Abstract

Introduction: The purpose of the present study was to investigate the effect of aerobic and resistance training during a Ketogenic Diet (KD) on serum levels of adipokines and insulin resistance indices in overweight or obese men. Method: A total of 36 overweight or obese men were randomly divided into three groups, namely Aerobic Training during KD (AT-KD), Resistance Training during KD (RT-KD), and KD alone (KD). In addition to following the KD, the training groups performed aerobic or resistance training three days per week for six weeks. For statistical analysis, the mixed two-way analysis of variance test with a significance level of less than 0.05 and SPSS software was used. Results: The serum levels of adiponectin, resistin, and SFRP5 did not differ significantly between the groups. In all groups, resistin had a significant decrease, whereas adiponectin and SFRP5 had a significant increase, compared to the pre-test. The serum levels of glucose, insulin, and triglycerides, as well as insulin resistance and sensitivity indices, were not significantly different between the groups. A significant decrease in glucose and triglyceride levels was observed in the three groups compared to the pre-test. Both KD and AT-KD groups significantly decreased insulin and HOMA-IR and increased McAuley indices compared to the pre-test. Only the AT-KD group significantly increased the QUICKI index compared to the pretest. Conclusion: Both AT-KD and RT-KD improved the level of adipokines in overweight or obese men. However, there was no difference between the two types of training. Despite the lack of difference between the two types of exercise, aerobic training may be more effective than resistance training during a KD
研究在生酮饮食期间进行两种类型的有氧和阻力训练对超重或肥胖男性血清脂肪因子水平和胰岛素抵抗的影响
简介:本研究的目的是探讨在生酮饮食(KD)期间有氧和阻力训练对超重或肥胖男性血清脂肪因子水平和胰岛素抵抗指数的影响。方法:将36名超重或肥胖男性随机分为三组,分别为KD时有氧训练组(AT-KD)、KD时阻力训练组(RT-KD)和单纯KD组(KD)。除了遵循KD外,训练组每周进行三天的有氧或阻力训练,持续六周。统计分析采用显著性水平小于0.05的混合双向方差分析检验,采用SPSS软件。结果:两组间血清脂联素、抵抗素、SFRP5水平无显著差异。在所有组中,与测试前相比,抵抗素显著降低,而脂联素和SFRP5显著增加。血清葡萄糖、胰岛素、甘油三酯水平以及胰岛素抵抗和敏感性指标在两组间无显著差异。与测试前相比,三组患者的葡萄糖和甘油三酯水平显著下降。与试验前相比,KD组和AT-KD组均显著降低胰岛素和HOMA-IR,升高McAuley指数。只有AT-KD组的QUICKI指数显著高于前测组。结论:AT-KD和RT-KD均可改善超重或肥胖男性的脂肪因子水平。然而,两种类型的训练之间没有差异。尽管两种类型的运动之间缺乏差异,有氧训练可能比阻力训练更有效
