Strenuous upper-extremity activity and/or exercise have traditionally been prescribed for breast cancer survivors with or at risk of developing lymphedema. The purpose of this study was to assess the effect of an acute bout of exercise on upper-limb volume and symptoms in breast cancer survivors, with the intent to provide pilot data to guide a subsequent larger study.
Twenty-three women who regularly participated in dragon-boat racing took part in the study. A single exercise bout was performed at a moderate intensity (rating of perceived exertion: 13-14) for 20 continuous minutes on an arm ergometer. The difference between affected and unaffected limb volume was assessed pre- and post-exercise via measurements of limb circumference at five time points.
Although limb volume increased following exercise in both limbs, the difference between the limbs remained stable at each measurement point. Only one participant was found to have an increase in arm-volume difference of >100 ml post intervention, and only four participants reported symptoms of tension and/or heaviness in the affected limb.
The results suggest that limb volume in breast cancer survivors increases after an acute bout of upper-limb exercise but that, for the majority of women, the response is not different between affected and unaffected limbs. Future research using a larger sample and more sensitive measurement methods are recommended.
传统上，剧烈的上肢活动和/或锻炼一直被推荐给患有淋巴水肿或有患淋巴水肿风险的乳腺癌幸存者。本研究的目的是评估一次急性运动对乳腺癌幸存者上肢体积和症状的影响，旨在提供初步数据以指导后续更大规模的研究。
23名经常参加龙舟比赛的女性参与了该研究。在手臂测力计上以中等强度（主观用力程度评级：13 - 14）持续进行20分钟的单次运动。通过在五个时间点测量肢体周长来评估运动前后患侧和未患侧肢体体积的差异。
尽管运动后双侧肢体体积均增加，但在每个测量点双侧肢体体积差异保持稳定。干预后仅发现一名参与者患侧手臂体积差异增加超过100毫升，且只有四名参与者报告患侧肢体有紧张和/或沉重感。
结果表明，乳腺癌幸存者在进行一次急性上肢运动后肢体体积会增加，但对于大多数女性而言，患侧和未患侧肢体的反应并无差异。建议未来采用更大样本和更敏感测量方法进行研究。
