Abstract：
OBJECTIVE: The aims are to determine the feasibility of an online-delivered resistance exercise program among racially diverse breast cancer survivors and to conduct an exploratory analysis of the intervention on muscular strength, physical activity levels, health-related quality of life, and self-efficacy.
METHODS: A 2-arm randomized controlled trial study design with assessments at pre- and post-intervention was used. Participants (n = 52) were recruited from clinics at the host institution and randomized to either intervention (n = 28) or minimal contact control (MCC) conditions (n = 24). All participants received a 12-week individualized resistance exercise prescription based on their baseline functional strength assessment. Intervention participants exercised one-on-one once per week over Zoom with an exercise trainer. MCC participants received no supervision. Descriptive statistics were used to determine feasibility and acceptability (primary outcomes). Repeated measures ANOVAs were used to examine exploratory outcomes.
RESULTS: The intervention demonstrated high rates for feasibility outcomes of enrollment (80.0%) and post-intervention assessment completion (92.9%). Acceptability outcomes were high for session attendance (98.0%) and satisfaction (Mscore = 4.87 out of 5, SD = .18). The intervention group increased upper- (p < .01) and lower- (p < .02) body strength compared to MCC condition.
CONCLUSIONS: The intervention was feasible, acceptable, and demonstrated increases in muscular strength. Limitations include a small sample recruited from one cancer center. Future research is needed to determine longitudinal impacts of resistance exercise on survivorship outcomes. Online-delivered resistance exercise shows promising efficacy among racially diverse breast cancer survivors.

摘要：
目的：目的是确定在不同种族的乳腺癌幸存者中实施在线抗阻运动计划的可行性，并对肌肉力量的干预进行探索性分析。身体活动水平,与健康相关的生活质量，和自我效能感。
方法：采用2组随机对照试验设计，在干预前后进行评估。参与者（n=52）从主办机构的诊所招募，并随机分为干预（n=28）或最小接触控制（MCC）条件（n=24）。所有参与者都根据基线功能强度评估接受了为期12周的个性化抗阻运动处方。干预参与者每周与锻炼教练在Zoom上进行一对一的锻炼。MCC参与者没有得到监督。描述性统计用于确定可行性和可接受性（主要结果）。重复测量ANOVAs用于检查探索性结果。
结果：干预措施显示出很高的入组可行性结果（80.0%）和干预后评估完成率（92.9%）。会议出勤率（98.0％）和满意度（5分的Mscore=4.87，SD=0.18）的可接受性结果较高。与MCC条件相比，干预组增加了较高（p<.01）和较低（p<.02）的身体强度。
结论：干预是可行的，可接受,肌肉力量增强.限制包括从一个癌症中心招募的小样本。需要进一步的研究来确定抵抗运动对生存结果的纵向影响。在线进行的抗阻运动在种族多样性的乳腺癌幸存者中显示出有希望的疗效。
结果：政府注册：NCT04562233，2020年9月18日。
