BACKGROUND/AIM: Regular physical activity and exercise improves quality of life and possibly reduces risk of disease relapse and prolongs survival in breast cancer survivors. The aim of this study was to evaluate the impact of a 3-week moderate intensity aerobic training, on aerobic capacity (VO2max) in breast cancer survivors.
A prospective, randomized clinical study included 18 female breast cancer survivors in stage I-IIIA, in which the primary treatment was accomplished at least 3 months before the study inclusion. In all the patients VO2max was estimated using the Astrand's protocol on a bicycle-ergometer (before and after 3 weeks of training), while subjective assessment of exertion during training were estimated by the Category-Ratio RPE Scale. Each workout lasted 21 minutes: 3 minutes for warm-up and cool-down each and 15 min of full training, 2 times a week. The workload in the group E1 was predefined at the level of 45% to 65% of individual VO2max, and in the group E2 it was based on subjective evaluation of exertion, at the level marked 4-6. Data on the subjective feeling of exertion were collected after each training course in both groups.
We recorded a statistically significant improvement in VO2max in both groups (E1--11.86%; E2--17.72%), with no significant differences between the groups. The workload level, determined by the percent of VO2max, was different between the groups E1 and E2 (50.47 +/- 7.02% vs 55.58 +/- 9.58%), as well as subjective perception of exertion (in the groups E1 and E2, 11.6% and 41.6% of training, respectively, was graded in the mark 6).
In our group of breast cancer survivors, a 3-week moderate intensity aerobic training significantly improved the level of VO2max.
背景/目的:规律的体育活动和锻炼可改善生活质量,并可能降低乳腺癌幸存者疾病复发的风险,延长生存期。本研究旨在评估为期3周的中等强度有氧训练对乳腺癌幸存者有氧能力(最大摄氧量)的影响。
一项前瞻性随机临床研究纳入了18名I-IIIA期女性乳腺癌幸存者,其主要治疗在纳入研究前至少3个月完成。所有患者均在自行车测力计上采用阿斯兰德方案评估最大摄氧量(训练前和训练3周后),同时通过类别比率主观用力程度评分量表评估训练期间的主观用力程度。每次锻炼持续21分钟:热身和放松各3分钟,全面训练15分钟,每周2次。E1组的工作量预先设定为个体最大摄氧量的45%至65%,E2组则基于主观用力程度评估,设定为4-6级。两组在每次训练课程后收集主观用力感觉的数据。
我们记录到两组的最大摄氧量均有统计学意义的改善(E1组为11.86%;E2组为17.72%),两组之间无显著差异。E1组和E2组由最大摄氧量百分比确定的工作量水平不同(分别为50.47±7.02%和55.58±9.58%),主观用力感觉也不同(E1组和E2组分别有11.6%和41.6%的训练被评为6级)。
在我们的乳腺癌幸存者组中,为期3周的中等强度有氧训练显著提高了最大摄氧量水平。
