Few mobile health resistance-based physical activity interventions have targeted community-dwelling adults. "Ecofit" is a multicomponent intervention that promotes resistance and aerobic activities using smartphone technology, outdoor gyms, and social support. This study evaluated process evaluation outcomes of the ecofit randomized controlled trial: (1) the acceptability and usability of the ecofit smartphone app and app user workouts; (2) perceptions of factors influencing outdoor gym use; and (3) the fidelity, reach, recruitment, and dose received of the ecofit program.
Process data were collected through program evaluation surveys at 3 months, and app usage data were collected via the intervention platform for up to 3 months. Data were analyzed using descriptive statistics.
The survey was completed by 57% (n = 69) of eligible participants. The majority (93%) believed the app provided them with sufficient information to perform muscle-strengthening activities. Approximately half (51%) agreed that the goal-setting function encouraged them to complete their workouts, and 42% agreed that the self-assessment helped them monitor progress. "Proximity" to outdoor gyms emerged as the most important factor for choosing locations to workout (mean = 5.5, SD = 1.1). Participants logged a median of 5.5 (interquartile range = 19) workouts and 1 (interquartile range = 1) upper- and lower-body muscular fitness self-assessment.
The ecofit app provided participants with sufficient skills to perform unsupervised resistance training exercises using mobile health. Only half of the participants regarded self-assessments and goal setting as useful, suggesting a need for modifications to how these are implemented. Mobile health remains a promising delivery platform to promote unsupervised resistance training, although more research is needed to improve uptake.
很少有基于移动健康的抗阻性体力活动干预措施针对社区居住的成年人。“Ecofit”是一种多组分干预措施，使用智能手机技术、户外健身房和社会支持来促进抗阻和有氧运动。本研究评估了 Ecofit 随机对照试验的过程评估结果：（1） Ecofit 智能手机应用程序和应用程序用户锻炼的可接受性和可用性；（2） 影响户外健身房使用的因素的看法；（3） Ecofit 计划的忠实度、覆盖范围、招募和接受剂量。
通过 3 个月的方案评估调查收集过程数据，并通过干预平台收集最多 3 个月的应用程序使用数据。使用描述性统计分析数据。
有资格参加的参与者中，有 57%（n=69）完成了调查。大多数（93%）人认为应用程序为他们提供了进行肌肉强化活动所需的足够信息。约有一半（51%）的人同意目标设定功能鼓励他们完成锻炼，42%的人同意自我评估有助于他们监测进展。“接近”户外健身房是选择锻炼地点的最重要因素（平均值=5.5，标准差=1.1）。参与者记录的中位数为 5.5（四分位距=19）次锻炼和 1（四分位距=1）次上下肢肌肉健身自我评估。
Ecofit 应用程序为参与者提供了足够的技能，可使用移动健康进行无人监督的抗阻训练。只有一半的参与者认为自我评估和目标设定有用，这表明需要对如何实施这些功能进行修改。移动健康仍然是促进无人监督的抗阻训练的有前途的交付平台，但需要进一步研究来提高使用率。
