Background:Resistance training (RT) yields physical and psychological benefits for women living with and beyond breast cancer (WBC). This study examined the feasibility of a virtually delivered 8-week socially supportive RT intervention among WBC and assessed changes in physical activity and body image.Methods:A pilot single-arm 8-week pre–post intervention study design was implemented. Forty-one WBC were matched as exercise partners and asked to complete two RT sessions per week—one with a qualified exercise professional (QEP) and one with their peer. Data were collected at baseline (T1), post-intervention (T2), and 20 weeks post-baseline (T3).Results:The enrolment rate was 42%, the attendance rate for the QEP sessions was 63.8% and 40.0% for the peer sessions, and the retention rate was 87%. No adverse events were reported. Total weekly minutes of RT significantly (p< 0.05) increased by 42 minutes/week during the intervention and significantly decreased by 25 min/week at follow-up. Upper and lower body muscle strength increased (p< 0.01) during the intervention. Increased RT was associated with favorable activity self-perceptions.Conclusions:This pilot intervention study was feasible, safe, and demonstrated preliminary evidence for increasing RT time and strength among WBC. Virtually delivered socially supportive RT interventions can improve access for WBC.
背景：抗阻训练（RT）为乳腺癌患者及康复期女性（WBC）带来生理和心理双重获益。本研究探讨了为期8周、以虚拟方式开展的社会支持性抗阻训练干预在WBC群体中的可行性，并评估其对体力活动和身体意象的影响。 方法：采用单臂预-后测干预的试点研究设计，周期为8周。41名WBC参与者被配对为运动伙伴，每周需完成两次抗阻训练——一次在专业运动指导师（QEP）监督下进行，另一次与同伴共同完成。数据采集时间点包括基线（T1）、干预后（T2）及基线后20周（T3）。 结果：研究招募率为42%，专业指导课程出席率为63.8%，同伴互助课程出席率为40%，总体保留率达87%。研究期间未报告不良事件。干预期间每周抗阻训练时长显著增加42分钟/周（p<0.05），随访期显著减少25分钟/周。上下肢肌肉力量在干预期间显著提升（p<0.01）。抗阻训练时长的增加与积极的活动自我认知呈正相关。 结论：本试点干预研究证实了虚拟化社会支持性抗阻训练在WBC群体中具有可行性与安全性，并为提升该群体的抗阻训练时长和肌肉力量提供了初步证据。虚拟化社会支持性抗阻训练可有效提高WBC群体的运动可及性。
