The aim of the study was to evaluate the impact of inertial training on the muscle strength, on breast-cancer-related lymphedema, and on quality of life in breast cancer survivors. After a mastectomy, 24 women (age, 66.2 ± 10.6 years) were randomized to a training (n = 12) or control group (n = 12). The training group performed inertial training twice per week for 6 weeks with a training load of about 70% of the maximal force. Before and after training, we tested the maximum force of shoulder flexors, extensors, abductors, and adductors; body composition; breast-cancer-related lymphedema; and disabilities of the arm, shoulder, and hand. Inertial training significantly improved the strength in all tested muscles (from 32 to 68%; effect size (ES) from 0.89 to 1.85 in the impaired limb and from 31 to 64%; ES from 0.86 to 1.57 in the unimpaired limb). However, changes in the control group were not significant. Quality of life improved following treatment; the disabilities of the arm, shoulder, and hand score decreased significantly by 24.5% (ES from—0.29 to 1.38), p ≤ 0.05 in the training group and by 3.99% (ES from −0.49 to 1.14) in the control group p > 0.05. Breast-cancer-related lymphedema and body composition did not change significantly after the intervention in either group. We recommend inertial training for increasing muscle strength and improving quality of life in breast cancer survivors.
本研究的目的是评估惯性训练对乳腺癌幸存者肌肉力量、乳腺癌相关淋巴水肿以及生活质量的影响。乳房切除术后，24名女性（年龄66.2±10.6岁）被随机分为训练组（n = 12）和对照组（n = 12）。训练组每周进行两次惯性训练，持续6周，训练负荷约为最大力量的70%。在训练前后，我们测试了肩部屈肌、伸肌、外展肌和内收肌的最大力量；身体成分；乳腺癌相关淋巴水肿；以及手臂、肩部和手部的功能障碍。惯性训练显著提高了所有测试肌肉的力量（受损肢体从32%提高到68%；效应量（ES）从0.89提高到1.85，未受损肢体从31%提高到64%；ES从0.86提高到1.57）。然而，对照组的变化不显著。治疗后生活质量有所改善；训练组手臂、肩部和手部功能障碍评分显著降低24.5%（ES从−0.29到1.38），p≤0.05，对照组降低3.99%（ES从−0.49到1.14），p>0.05。两组干预后乳腺癌相关淋巴水肿和身体成分均无显著变化。我们建议进行惯性训练以增强乳腺癌幸存者的肌肉力量并改善其生活质量。
