Background

Although it is known that resistance training can be as effective as stretch training to increase joint range of motion, to date no comprehensive meta-analysis has investigated the effects of resistance training on range of motion with all its potential affecting variables.

Objective

The objective of this systematic review with meta-analysis was to evaluate the effect of chronic resistance training on range of motion compared either to a control condition or stretch training or to a combination of resistance training and stretch training to stretch training, while assessing moderating variables.

Design

For the main analysis, a random-effect meta-analysis was used and for the subgroup analysis a mixed-effect model was implemented. Whilst subgroup analyses included sex and participants’ activity levels, meta-regression included age, frequency, and duration of resistance training.

Data Sources

Following the systematic search in four databases (PubMed, Scopus, SPORTDiscus, and Web of Science) and reference lists, 55 studies were found to be eligible.

Eligibility Criteria

Controlled or randomized controlled trials that separately compared the training effects of resistance training exercises with either a control group, stretching group, or combined stretch and resistance training group on range of motion in healthy participants.

Results

Resistance training increased range of motion (effect size [ES] = 0.73; p < 0.001) with the exception of no significant range of motion improvement with resistance training using only body mass. There were no significant differences between resistance training versus stretch training (ES = 0.08; p = 0.79) or between resistance training and stretch training versus stretch training alone (ES = − 0.001; p = 0.99). Although “trained or active people” increased range of motion (ES = 0.43; p < 0.001) “untrained and sedentary” individuals had significantly (p = 0.005) higher magnitude range of motion changes (ES = 1.042; p < 0.001). There were no detected differences between sex and contraction type. Meta-regression showed no effect of age, training duration, or frequency.

Conclusions

As resistance training with external loads can improve range of motion, stretching prior to or after resistance training may not be necessary to enhance flexibility.

阻力训练诱导运动范围的改善：系统回顾和荟萃分析

背景

虽然众所周知，阻力训练与拉伸训练一样有效，可以增加关节活动范围，但迄今为止，还没有全面的荟萃分析研究阻力训练对运动范围的影响及其所有潜在影响变量。

客观的

本系统评价与荟萃分析的目的是评估慢性阻力训练对运动范围的影响，与控制条件或拉伸训练相比，或者与阻力训练和拉伸训练相结合的拉伸训练，同时评估调节变量.

设计

主要分析采用随机效应荟萃分析，亚组分析采用混合效应模型。虽然亚组分析包括性别和参与者的活动水平，但元回归包括年龄、频率和阻力训练的持续时间。

数据源

在对四个数据库（PubMed、Scopus、SPORTDiscus 和 Web of Science）和参考文献列表进行系统搜索后，发现 55 项研究符合条件。

资格标准

对照或随机对照试验，分别比较阻力训练与对照组、拉伸组或拉伸和阻力联合训练组对健康参与者运动范围的训练效果。

结果

阻力训练增加了运动范围（效果大小 [ES] = 0.73；p < 0.001），除了仅使用体重的阻力训练没有显着改善运动范围。阻力训练与拉伸训练之间（ES = 0.08； p = 0.79）或阻力训练和拉伸训练与单独拉伸训练之间没有显着差异（ES = − 0.001； p = 0.99）。尽管“受过训练或活跃的人”增加了运动范围 (ES = 0.43; p < 0.001)，但“未受过训练和久坐”的人的运动范围变化幅度显着 ( p = 0.005) (ES = 1.042; p < 0.001)。性别和收缩类型之间没有检测到差异。元回归显示年龄、训练持续时间或频率没有影响。
