Randomized-controlled trial (RCT) with immediate intervention (IMM) and wait-list control (WLC) groups; WLC participants received the intervention during delivery to subsequent cohorts.
Investigate the effectiveness and feasibility of a virtually-delivered exercise intervention.
Home and community.
A total of 168 middle-aged (49.6 [12.3] years old) men (57%) and women (43%) who lived an average 15.5 (12.3) years with spinal cord injury (SCI) participated. The 16-week program provides users (a) website access with exercise information, resources, and 16 skill-building modules; (b) virtual 60-minute, group-based weekly meetings; and (c) a starter package of exercise equipment. Primary outcomes included subjective physical activity (IPAQ) and objective exercise (Polar A300 wrist-based activity monitor and H7 heart rate strap). Secondary outcomes included fitness indices during a maximal arm crank test, plus self-reported exercise barriers, exercise self-efficacy, and goal-directed thinking.
RCT results indicate significant between group differences in participants' self-reported weekly time spent in vigorous-intensity PA and goal directed thinking but not for fitness changes. Data combined for IMM and WLC participants from Polar monitoring show participants performed 150 min per week of aerobic exercise plus reported significantly greater time spent in moderate-PA, vigorous-PA, self-efficacy for exercise and nutrition, goal directed thinking, and exercise barriers. Oxygen uptake (V̇O peak) and power output (watts max) were the only physiologic measures to demonstrate significant change, with a moderate effect size.
This virtually-delivered program offers a promising approach to increase exercise among those with SCI and may help participants perceive fewer motivational barriers and greater self-efficacy.
随机对照试验（RCT），包括即时干预（IMM）组和等待名单对照（WLC）组；WLC 组的参与者在分娩时接受干预，然后进入后续队列。
研究一种虚拟传递的运动干预措施的有效性和可行性。
家庭和社区。
共有 168 名年龄在 49.6（12.3）岁的中年男性（57%）和女性（43%）参与了研究，他们平均患有脊髓损伤（SCI）15.5（12.3）年。该 16 周的方案为用户提供：（a）网站访问权限，包括运动信息、资源和 16 个技能建设模块；（b）虚拟的每周 60 分钟、基于小组的会议；（c）运动设备的启动包。主要结果包括主观体力活动（IPAQ）和客观运动（Polar A300 腕部活动监测器和 H7 心率带）。次要结果包括最大手臂曲柄测试期间的健身指数，以及自我报告的运动障碍、运动自我效能和目标导向思维。
RCT 结果表明，参与者自我报告的每周剧烈强度体育活动时间和目标导向思维方面存在显著的组间差异，但在健身变化方面则没有差异。结合 Polar 监测数据，对 IMM 和 WLC 参与者的数据进行分析表明，参与者每周进行 150 分钟的有氧运动，并且报告的中等强度体育活动、剧烈强度体育活动、运动和营养自我效能、目标导向思维和运动障碍时间显著增加。摄氧量（V̇Opeak）和功率输出（瓦特最大值）是唯一显示出显著变化的生理指标，具有中等效应量。
这种虚拟传递的方案为增加脊髓损伤患者的运动提供了一种有前途的方法，可能有助于参与者感知到较少的动机障碍和更大的自我效能。
