The strict lockdown implemented due the COVID-19 pandemic is generating a great impact on wellbeing and health-related quality of life (HRQoL) in people with cancer. We aimed to evaluate the efficacy and feasibility of an online home-based exercise intervention performed during a lockdown period analysing its effects on body composition, physical fitness, and HRQoL in breast cancer survivors.
Fifteen women with breast cancer receiving hormonal therapy (55.5 ± 6.7 years) were included in the study. The exercise intervention consisted of two weekly sessions of remotely supervised functional training (60 min per day) and two weekly sessions of unsupervised aerobic training (20-30 min/session; 60-85% of maximum heart rate) for a total of 16 weeks. DXA absorptiometry was used for the assessment of body composition. Functional assessment included cardiorespiratory fitness (CRF) by Rockport walking test, upper and lower body strength (grip strength, arm curl test, and chair stand test), walking speed (brisk walking test), and agility (8-foot up-and-go test). The HRQoL was evaluated with the QLQ-BR23 questionnaire. The adherence to the intervention was measured as the percentage of online classes attended.
Rate of adherence for the online exercise intervention was 90 ± 17%. The exercise intervention induced significant (p < 0.05) improvements in physical fitness: CRF (+ 9%), right arm and lower limb strength (+ 10% and + 18%, respectively) and lower limbs lean mass (+ 2% and + 3.5% for left and right leg, respectively).
This feasibility study suggests that an online home-based exercise intervention during COVID-19 lockdown could improve physical fitness and body composition in breast cancer survivors even in a context of heightened concern for future health.
由于 COVID-19 大流行而实施的严格封锁对癌症患者的幸福感和健康相关生活质量（HRQoL）产生了重大影响。我们旨在评估在封锁期间进行在线家庭运动干预的效果和可行性，并分析其对乳腺癌幸存者的身体成分、身体适应性和 HRQoL 的影响。
本研究纳入了 15 名接受激素治疗的乳腺癌女性（55.5±6.7 岁）。运动干预包括每周两次远程监督的功能性训练（每天 60 分钟）和每周两次非监督的有氧运动训练（每次 20-30 分钟；最大心率的 60-85%），总共有 16 周。双能 X 线吸收法用于评估身体成分。功能评估包括心肺适应性（Rockport 步行测试）、上下肢力量（握力、手臂卷曲测试和椅子站立测试）、步行速度（快步走测试）和敏捷性（8 英尺上落测试）。HRQoL 通过 QLQ-BR23 问卷进行评估。通过在线课程的出席百分比来衡量对干预的依从性。
在线运动干预的依从率为 90±17%。运动干预显著改善了身体适应性（p<0.05）：心肺适应性（+9%）、右臂和下肢力量（分别增加 10%和 18%）以及下肢瘦体重（左腿和右腿分别增加 2%和 3.5%）。
这项可行性研究表明，在 COVID-19 封锁期间进行在线家庭运动干预可以提高乳腺癌幸存者的身体适应性和身体成分，即使在对未来健康的担忧加剧的情况下也是如此。
