Cardiorespiratory function and exercise tolerance appear very limited in persons with rheumatoid arthritis (RA). Many studies have demonstrated that aerobic exercise training is beneficial to prevent physical deconditioning without inducing adverse effects on an individual's joints and general health. The present study was conducted to demonstrate that a dance-based exercise program is a safe and efficient activity to improve physical fitness and psychological state in persons with RA. A group of 19 persons (mean age, 49.3 +/- 13 yr) participated in a 12-wk exercise program (twice weekly), whereas 10 persons (mean age, 49.4 +/- 12 yr) served as controls. Health status, use of medication, joint pain and swelling, physical fitness, activity of daily living and psychological state were assessed at baseline, after the 12-wk training program and 6 mo after the end of the program. Exercise training induced a mean improvement of 13% in aerobic power, with the highest values reaching 40%. No significant changes were observed in joint status, even though the count of painful joints tended to decrease in the exercise group. Positive changes in depression, anxiety, fatigue and tension were observed after the 12-wk exercise program. These findings provide some evidences in favor of aerobic exercise in individuals with RA. Furthermore, it is of primary interest to note that a weight-bearing activity with limited ground impacts do not provoke short-term adverse effects on joint status. Further studies, however, are required to determine the long-term effect of weight-bearing exercise on the health status of individuals with RA.
类风湿关节炎（RA）患者的心肺功能和运动耐力似乎非常有限。许多研究表明，有氧运动训练有利于预防身体机能下降，且不会对个体关节和总体健康产生不利影响。本研究旨在证明，基于舞蹈的运动计划是一种安全有效的活动，可改善RA患者的身体素质和心理状态。一组19人（平均年龄49.3±13岁）参加了为期12周的运动计划（每周两次），而10人（平均年龄49.4±12岁）作为对照组。在基线、12周训练计划结束后以及计划结束后6个月，对健康状况、药物使用情况、关节疼痛和肿胀、身体素质、日常生活活动能力和心理状态进行了评估。运动训练使有氧能力平均提高了13%，最高值达到40%。尽管运动组中疼痛关节的数量有减少趋势，但关节状况未观察到显著变化。在为期12周的运动计划后，观察到抑郁、焦虑、疲劳和紧张方面有积极变化。这些发现为RA患者进行有氧运动提供了一些证据。此外，值得注意的是，一种对地面冲击有限的负重活动不会对关节状况产生短期不利影响。然而，需要进一步研究来确定负重运动对RA患者健康状况的长期影响。
