摘要

背景:肥胖症是一种荷尔蒙代谢紊乱疾病,由于生活方式的改变,尤其是缺乏运动和遗传倾向,导致脂肪在体内异常或过度堆积。研究目的本研究旨在比较 8 周有氧训练和阻力训练对超重和肥胖女性血清肌连蛋白水平和胰岛素抵抗的影响。研究方法共有 45 名年龄在 30-50 岁之间的超重或肥胖女性参与了本研究。研究对象被随机分为三组,每组 15 人:对照组(I 组)、阻力训练组(II 组)和有氧训练组(III 组)。有氧训练组按照逐渐超负荷的原则,进行为期八周的跑步训练,强度设定为最大心率的 50% - 70%。阻力训练组完成了为期八周的训练计划,每周三次。所有数据均使用 SPSS 软件(26 版)进行分析。采用重复测量的双向方差分析和 Bonferroni 后检验,显著性设定为 P≥ 0.05。结果与对照组相比,有氧运动和阻力运动导致的血清肌连蛋白水平差异具有统计学意义(分别为 P = 0.024 和 P = 0.002)。然而,有氧运动和阻力运动对这一变量的影响无明显差异(P = 0.214)。同样,与对照组相比,有氧运动和阻力运动导致的胰岛素抵抗在统计学上有显著差异(分别为 P = 0.028 和 P = 0.001),有氧运动和阻力运动对这一变量的影响之间没有观察到显著差异(P = 0.068)。结论总之,肥胖或超重女性分别进行为期 8 周的有氧运动和抗阻力训练可提高血清肌连蛋白水平,改善胰岛素抵抗。上述发现共同表明,新陈代谢状况得到改善,有助于个人整体健康的提高。

Comparison of Aerobic and Resistance Exercises on Myonectin Levels and Insulin Resistance in Overweight and Obese Women
Background: Obesity is a hormonal-metabolic disorder that leads to the abnormal or excessive accumulation of fat in the body due to lifestyle changes, especially inactivity and genetic predispositions. Objectives: The present study aimed to compare the effects of 8 weeks of aerobic and resistance training on serum myonectin levels and insulin resistance in overweight and obese women. Methods: A total of 45 women aged 30 - 50 years who were either overweight or obese participated in this study. The subjects were randomly divided into three groups, each consisting of 15 participants: control (group I), resistance training (group II), and aerobic training (group III). The aerobic training group engaged in an eight-week running program with an intensity set at 50 - 70% of their maximum heart rate, following the principle of gradual overload. The resistance training group completed an 8-week program with three sessions per week. All data were analyzed using SPSS software (version 26). Two-way analysis of variance in repeated measures and Bonferroni’s post hoc test were utilized, with significance set at P ≥ 0.05. Results: Both aerobic and resistance exercises resulted in a statistically significant difference in serum myonectin levels compared to the control group (P = 0.024 and P = 0.002, respectively). However, no significant difference was observed between the effects of aerobic and resistance exercises on this variable (P = 0.214). Similarly, both aerobic and resistance exercises led to a statistically significant difference in insulin resistance, compared to the control group (P = 0.028 and P = 0.001, respectively), with no significant difference observed between the effects of aerobic and resistance exercises on this variable (P = 0.068). Conclusions: In conclusion, 8 weeks of aerobic and resistance training, when performed separately by obese or overweight women, resulted in increased serum myonectin levels and improved insulin resistance. The aforementioned findings collectively indicate an enhancement in metabolic status, contributing to overall health improvement in individuals.
