Resistance training (RT) is recommended as part of our national physical activity guidelines which includes working all major muscle groups on two or more days a week.Older adults can gain many health benefits from RT, such as increased muscle strength,increased muscle mass, and maintenance of bone density. Additionally, certain dimensions of health-related quality of life (HRQOL) have been shown to improve in older adults due to RT intervention. The purpose of this study was to use systematic review and meta-analytic techniques to examine the effect of RT on HRQOL in older adults. A systematic review of current studies (2008 thru 2017) was conducted using PubMed. Studies were included if they used a randomized controlled design, had RT as an intervention, measured HRQOL using the SF-36/12 assessment, and included adults 50+ years of age. Eight dimension scores (physical functioning, bodily pain, physical role function, general health, mental health, emotional role function, social function, and vitality) and two summary scores (physical component and mental component) were extracted. Ten meta-analyses were performed using standardized mean effect sizes and random effects models. Study quality,moderator and sensitivity analyses were conducted. A total of 16 studies were included in the analyses with a mean Physiotherapy Evidence Database (PEDro) score of 4.9 (SD=1.0). Among the mental health measures, RT had the greatest effect on mental health (Effect size [ES]=0.64, 95% CI: 0.30-0.99, I=79.7). Among the physical health measures, RT had the largest effect on body pain (ES=0.81, 95% CI: 0.26-1.35, I=85.9).Initially, RT did not significantly affect measures of emotional role function, social function or physical role function. However, after removing a single study, RT significantly increased all HRQOL measures. The meta-analytic evidence presented in this research clearly supports the promotion of RT in improving HRQOL in older adults.
抗阻训练（RT）被推荐作为我们国家体育活动指南的一部分，该指南包括每周两天或更多天锻炼所有主要肌肉群。老年人可以从抗阻训练中获得许多健康益处，如肌肉力量增强、肌肉量增加以及骨密度维持。此外，由于抗阻训练干预，老年人健康相关生活质量（HRQOL）的某些方面已显示有所改善。本研究的目的是使用系统评价和荟萃分析技术来检验抗阻训练对老年人健康相关生活质量的影响。使用PubMed对当前研究（2008年至2017年）进行了系统评价。如果研究采用随机对照设计、将抗阻训练作为干预措施、使用SF - 36/12评估来测量健康相关生活质量且纳入50岁及以上成年人，则纳入该研究。提取了八个维度得分（身体功能、身体疼痛、身体角色功能、总体健康、心理健康、情感角色功能、社会功能和活力）以及两个汇总得分（身体成分和心理成分）。使用标准化平均效应量和随机效应模型进行了十项荟萃分析。进行了研究质量、调节因素和敏感性分析。分析共纳入16项研究，平均物理治疗证据数据库（PEDro）评分为4.9（标准差 = 1.0）。在心理健康指标中，抗阻训练对心理健康的影响最大（效应量[ES]=0.64，95%置信区间：0.30 - 0.99，I² = 79.7）。在身体健康指标中，抗阻训练对身体疼痛的影响最大（ES = 0.81，95%置信区间：0.26 - 1.35，I² = 85.9）。最初，抗阻训练对情感角色功能、社会功能或身体角色功能的指标没有显著影响。然而，在剔除一项研究后，抗阻训练显著提高了所有健康相关生活质量指标。本研究中呈现的荟萃分析证据明确支持推广抗阻训练以改善老年人的健康相关生活质量。
