Although the general assumption is that patients with rheumatoid arthritis (RA) have decreased levels of physical activity, no review has addressed whether this assumption is correct.
Our objective was to systematically review the literature for physical activity levels and aerobic capacity (VO2max). in patients with (RA), compared to healthy controls and a reference population. Studies investigating physical activity, energy expenditure or aerobic capacity in patients with RA were included. Twelve studies met our inclusion criteria.
In one study that used doubly labeled water, the gold standard measure, physical activity energy expenditure of patients with RA was significantly decreased. Five studies examined aerobic capacity. Contradictory evidence was found that patients with RA have lower VO2max than controls, but when compared to normative values, patients scored below the 10th percentile. In general, it appears that patients with RA spend more time in light and moderate activities and less in vigorous activities than controls.
Patients with RA appear to have significantly decreased energy expenditure, very low aerobic capacity compared to normative values and spend less time in vigorous activities than controls.
尽管人们普遍认为类风湿关节炎（RA）患者的身体活动水平较低，但尚无研究探讨这一假设是否正确。
我们的目的是系统地回顾文献中 RA 患者的身体活动水平和有氧能力（VO2max），并与健康对照组和参考人群进行比较。纳入研究 RA 患者身体活动、能量消耗或有氧能力的文章。
在一项使用双标记水（金标准测量方法）的研究中，RA 患者的身体活动能量消耗明显减少。五项研究检查了有氧能力。结果发现，RA 患者的 VO2max 低于对照组，但与正常值相比，患者的得分低于第 10 百分位。一般来说，RA 患者似乎比对照组花费更多的时间在轻中度活动中，而花费在剧烈活动中的时间较少。
RA 患者的能量消耗明显减少，与正常值相比有氧能力极低，且剧烈活动时间比对照组少。
