INTRODUCTION/PURPOSE: Virtually supervised, group-based exercise presents an innovative way to expand the reach of exercise-oncology programs and help cancer survivors increase physical activity (PA) and connect with other participants. This study examined the feasibility, acceptability, and preliminary effects of a group-based PA program delivered exclusively using videoconferencing software.
This study used a single-group pre-post design. The 8-wk program consisted of aerobic and resistance exercise sessions once per week and three PA behavior change discussion sessions in groups of four to six. Feasibility was determined by enrollment, retention, safety, and adherence. Postprogram surveys evaluated acceptability using a Likert scale and open-ended responses. Changes in PA (Godin Leisure-Time Exercise Questionnaire), quality of life (QOL; Functional Assessment of Cancer Therapy- General), and upper and lower body muscular endurance (bicep curl and sit-to-stand test) were also evaluated.
Enrollment was feasible ( = 61 of 65 who expressed interest in the program), and retention (86.9%) and adherence (88% for exercise, 91% for discussion) were high; no adverse events were reported. Participants (mean age, 59.9 ± 10.1 yr; 96.2% female; 64.2% ovarian cancer, 28.3% breast cancer, 7.5% other cancer) reported they enjoyed the program (median, 7 of 7), and videoconferencing software was easy to use and had good video and audio quality (median, 5 of 5). From preprogram to postprogram, participants increased their weekly minutes of aerobic (mean (SD) change, 82.4 (144.2)) and resistance (mean (SD) change, 31.9 (42.7)) PA; sit-to-stand (mean (SD) change, 1.4 (3.9)) and bicep curl (mean (SD) change, 5.3 (6.8)) repetitions; and emotional (mean (SD) change, 0.82 (2.3) points), functional (mean (SD) change, 1.2 (3.6) points), and total QOL (mean (SD) change, 3 (7.9) points; all < 0.05).
A group-based PA program delivered using videoconference technology is feasible and acceptable for cancer survivors, and may increase PA and improve physical fitness and some aspects of QOL. A larger, controlled intervention is needed to determine efficacy, as well as pragmatic studies to directly compare this approach with conventional strategies (i.e., face-to-face programs).
引言/目的：虚拟监督的、基于群体的运动提供了一种创新方式，可扩大运动肿瘤学项目的覆盖范围，并帮助癌症幸存者增加身体活动（PA），以及与其他参与者建立联系。本研究考察了仅使用视频会议软件开展的基于群体的PA项目的可行性、可接受性和初步效果。
本研究采用单组前后测设计。为期8周的项目包括每周一次的有氧运动和抗阻运动课程，以及四至六人一组的三次PA行为改变讨论课程。通过招募、留存、安全性和依从性来确定可行性。项目结束后的调查使用李克特量表和开放式回答来评估可接受性。还评估了PA（戈丁休闲时间运动问卷）、生活质量（QOL；癌症治疗功能评估-通用版）以及上下肢肌肉耐力（二头肌弯举和坐立试验）的变化。
招募是可行的（65名表示对该项目感兴趣的人中61人入选），留存率（86.9%）和依从性较高（运动课程为88%，讨论课程为91%）；未报告不良事件。参与者（平均年龄59.9±10.1岁；96.2%为女性；64.2%为卵巢癌，28.3%为乳腺癌，7.5%为其他癌症）报告他们喜欢该项目（中位数为7分，满分7分），视频会议软件易于使用，视频和音频质量良好（中位数为5分，满分5分）。从项目开始前到项目结束后，参与者每周的有氧运动分钟数（平均（标准差）变化为82.4（144.2））和抗阻运动分钟数（平均（标准差）变化为31.9（42.7））增加；坐立试验重复次数（平均（标准差）变化为1.4（3.9））和二头肌弯举重复次数（平均（标准差）变化为5.3（6.8））增加；情绪方面（平均（标准差）变化为0.82（2.3）分）、功能方面（平均（标准差）变化为1.2（3.6）分）以及总QOL（平均（标准差）变化为3（7.9）分；均P<0.05）。
使用视频会议技术开展的基于群体的PA项目对癌症幸存者来说是可行且可接受的，可能会增加PA，改善身体素质和QOL的某些方面。需要进行更大规模的对照干预来确定疗效，以及进行务实研究，将这种方法与传统策略（即面对面项目）进行直接比较。
