Background

Overweight and obesity are associated with musculoskeletal pain, particularly in the female population. However, regular resistance training may positively affect these complaints.

Objective

The present study aimed to investigate between group differences in musculoskeletal pain in previously inactive women, allocated to three different resistance-training modalities available in health- and fitness clubs.

Methods

This is secondary analysis from a single-blinded randomized controlled trial, including healthy women (aged 18–65) with a BMI (kg/m²) ≥25. The participants were allocated to 12 weeks (3 times/weekly) of either BodyPump (high-repetition low-load group session) (n = 24), heavy load resistance training with a personal trainer (n = 28), non-supervised heavy load resistance training (n = 19) or non-exercising controls (n = 21). Primary outcome was self-reported musculoskeletal pain in ten different body parts, measured with the Standardized Nordic Pain Questionnaire, at baseline and post-test. In addition, the study included sub-analyses of the participants when they were divided into high (≥28 of 36 sessions, n = 38) and low (≤27 of 36 sessions, n = 22) exercise adherence.

Results

The analysis revealed no between group differences in musculoskeletal pain in any of the ten body parts. The results did not change when the participants were divided into high versus low adherence.

Conclusions

Twelve weeks of BodyPump, heavy load resistance training with a personal trainer and non-supervised heavy load resistance training did not show any effect on self-reported musculoskeletal pain in overweight women.

低负荷训练和重负荷训练是否会影响超重和肥胖妇女的肌肉骨骼疼痛？一项随机对照试验的二级分析。

背景

超重和肥胖与肌肉骨骼疼痛有关，特别是在女性人群中。但是，定期的抵抗训练可能会对这些抱怨产生积极影响。

目的

本研究旨在调查以前不运动的女性的肌肉骨骼疼痛的群体差异，并将其分配给健身俱乐部和健身俱乐部中可用的三种不同的抵抗训练模式。

方法

这是来自一项单盲随机对照试验的二级分析，该试验包括BMI（kg / m ²）≥25的健康女性（18-65岁）。参与者被分配为12周（每周3次，每周3次），分别为BodyPump（高重复性低负荷小组 训练）（n = 24），由私人教练进行的重负荷耐力训练（n  = 28），无人监督的重型负荷阻力训练（n  = 19）或非运动控制（n  = 21）。主要结果是在基线和测试后用标准北欧疼痛问卷测量的十个身体部位的自我报告的肌肉骨骼疼痛。此外，该研究还包括将参与者分为高水平（36个疗程中≥28个，n  = 38）和低度运动（坚持36次，≤27次，n  = 22）。

结果

分析显示，在十个身体部位的任何部位，肌肉骨骼疼痛的组间差异均无。当参与者分为高依从性和低依从性时，结果没有改变。

结论

十二周的BodyPump训练，私人教练的重负荷阻力训练和无​​监督的重负荷阻力训练对超重女性自我报告的肌肉骨骼疼痛没有任何影响。
