Perceptions of Immersive Virtual Reality for Physical Activity Among Individuals with Hypertension at Risk of Cardiovascular Disease: A Qualitative Study.

Background: Hypertension, obesity, and a sedentary lifestyle are interrelated, forming a vicious cycle that deteriorates cardiovascular health. In addition to being a pathology, hypertension is a risk factor for cardiovascular diseases, one of the leading causes of mortality worldwide. Interventions that combine weight loss and physical activity (PA) reduce cardiovascular risk, but many people face barriers in adhering to regular PA regimens such as a lack of time or motivation. Immersive virtual reality (IVR) has emerged as an innovative alternative to promote PA. This study explored the perceptions of individuals with hypertension and cardiovascular risk regarding the use of IVR as a tool for PA. Methods: Fifteen hypertensive adults with cardiovascular risk completed twelve IVR exercise sessions over thirty days. Semi-structured interviews were conducted. Results: The thematic analysis identified three main themes: (1) PA, sedentary lifestyle, and health; (2) experiences and perceptions of IVR and PA; and (3) IVR as a useful and safe tool. The participants found IVR engaging, motivating, and effective in overcoming barriers such as a lack of time and social anxiety. Gamification and immersion facilitated greater adherence and enjoyment. Conclusions: The participants of this study perceived IVR as an innovative, engaging, and motivating tool for promoting PA. The participants positively valued IVR's ability to overcome common barriers such as lack of time, adverse weather conditions, and lack of motivation, as well as its immersive and gamified features, which enhanced the adherence to and enjoyment of PA. These results suggest that IVR could complement traditional exercise programs by facilitating the initiation of active routines in sedentary individuals.
