To examine the effect of high-intensity progressive resistance strength training (HIPRST) on strength, function, mood, quality of life, and adverse events compared with other intensities in older adults.
Online databases were searched from their inception to July 2012.
Randomized controlled trials of HIPRST of the lower limb compared with other intensities of progressive resistance strength training (PRST) in older adults (mean age ≥ 65y) were identified.
Two reviewers independently completed quality assessment using the Physiotherapy Evidence Database (PEDro) scale and data extraction using a prepared checklist.
Twenty-one trials were included. Study quality was fair to moderate (PEDro scale range, 3-7). Studies had small sample sizes (18-84), and participants were generally healthy. Meta-analyses revealed HIPRST improved lower-limb strength greater than moderate- and low-intensity PRST (standardized mean difference [SMD]=.79; 95% confidence interval [CI], .40 to 1.17 and SMD=.83; 95% CI, -.02 to 1.68, respectively). Studies where groups performed equivalent training volumes resulted in similar improvements in leg strength, regardless of training intensity. Similar improvements were found across intensities for functional performance and disability. The effect of intensity of PRST on mood was inconsistent across studies. Adverse events were poorly reported, however, no correlation was found between training intensity and severity of adverse events.
HIPRST improves lower-limb strength more than lesser training intensities, although it may not be required to improve functional performance. Training volume is also an important variable. HIPRST appears to be a safe mode of exercise in older adults. Further research into its effects on older adults with chronic health conditions across the care continuum is required.
比较高强度渐进式抗阻力量训练（HIPRST）与其他强度在老年人中的力量、功能、情绪、生活质量和不良事件的影响。
从成立到 2012 年 7 月，在线数据库进行了搜索。
确定了比较老年人下肢 HIPRST 与其他渐进式抗阻力量训练（PRST）强度的随机对照试验（平均年龄≥65 岁）。
两位评审员独立使用物理治疗证据数据库（PEDro）量表进行质量评估，并使用准备好的清单进行数据提取。
共纳入 21 项试验。研究质量为中等至良好（PEDro 量表范围，3-7）。研究样本量较小（18-84），参与者通常较为健康。荟萃分析显示，HIPRST 比中、低强度 PRST 更能提高下肢力量（标准化均数差 [SMD] =.79；95%置信区间 [CI]，.40 至 1.17 和 SMD=.83；95% CI， -.02 至 1.68）。当组进行等效训练量时，无论训练强度如何，腿部力量都会得到相似的改善。在不同强度下，功能表现和残疾的改善情况也相似。PRST 强度对情绪的影响在研究之间不一致。然而，不良事件报告不佳，也没有发现训练强度与不良事件严重程度之间存在相关性。
HIPRST 比低强度训练更能提高下肢力量，尽管可能不需要提高功能表现。训练量也是一个重要的变量。HIPRST 似乎是老年人安全的运动方式。需要进一步研究其对整个医疗保健连续性中患有慢性健康状况的老年人的影响。
