Insufficient physical activity is one of the most important risk factors for non-communicable diseases. Physical activity should therefore be intensively promoted in all age groups. Several trials suggest that it can be effectively increased through smartphone interventions.However, few of the smartphone-interventions available on the market have been scientifically evaluated. Therefore, the described study aims to assess the short-term and long-term effects of the smartphone intervention 'VIDEA bewegt' to increase physical activity. The trial is designed as a single-armed observational trial to assess effects under real-life conditions.
The intervention consists of the smartphone-application 'VIDEA bewegt', which is a video-based preventative programme to improve physical activity in everyday life. The application contains several features and components including educational videos, documentation of activity and motivational exercises. A sample size of at least 106 participants is aimed for.The primary objective of this study is to determine the effect of the application on physical activity in German adults. Secondary objectives are to evaluate the self-efficacy, health-related quality of life and usability of 'VIDEA bewegt'.Data collection is based on online questionnaires, as well as system-internal recorded data.Changes of outcomes from baseline to programme completion and follow-up will be calculated.
The Ethics Committee of the Technical University Dresden approved the study on 25 May 2019 (EK 272062019). All data are processed anonymously and stored on servers only accessible by authorised personnel. The results of the study and the results of the usability test are aimed to be published in a scientific journal.

身体活动不足是导致非传染性疾病的最重要危险因素之一。因此，应在所有年龄段大力促进身体活动。多项试验表明，通过智能手机干预可以有效地增加身体活动量。然而，市场上可用的智能手机干预措施中，很少有经过科学评估的。因此，本研究旨在评估智能手机干预“VIDEA bewegt”对增加身体活动量的短期和长期效果。该试验设计为单臂观察性试验，以评估实际条件下的效果。
干预措施包括智能手机应用程序“VIDEA bewegt”，这是一个基于视频的预防性计划，旨在提高日常生活中的身体活动量。该应用程序包含多个功能和组件，包括教育视频、活动记录和激励练习。目标样本量至少为 106 名参与者。本研究的主要目的是确定该应用程序对德国成年人身体活动的影响。次要目标是评估“VIDEA bewegt”的自我效能感、健康相关生活质量和可用性。数据收集基于在线问卷以及系统内部记录的数据。将根据基线到计划完成和随访期间的结果变化进行计算。
德累斯顿技术大学伦理委员会于 2019 年 5 月 25 日批准了该研究（EK 272062019）。所有数据均以匿名方式处理，并仅存储在授权人员可访问的服务器上。该研究的结果和可用性测试的结果旨在发表在科学期刊上。
