Effects of an Immersive Virtual Reality Program

Overview

A tool that could be useful to eliminate the barriers of not practicing physical activity can be immersive virtual reality, which is characterized by being a technique where a person, through the use of a screen mounted on the head, receives images, sounds and tactile sensations of a simulated world. In the area of physical exercise, evidence places immersive virtual reality as a tool that encourages healthy behaviors and the practice of physical activity, increasing adherence to exercise in the long term. In addition to the fact that performing physical activity by this means generates a high level of enjoyment in the participants, so if the use of this technology generates enjoyment in those who use it and contributes to complying with the recommendations of physical activity, it is logical to think that a physical exercise program executed through immersive virtual reality could contribute to improving parameters related to people's health. Therefore, the objective of this randomized controlled trial is to evaluate the effect of a physical exercise program carried out through immersive virtual reality on health-related variables.

Physical fitness (PF) is a measure that integrates most of the body's functions that are involved during the performance of any physical activity or physical exercise. Although its variation depends largely on genetic components, the physical exercise factor is one of the environmental conditioning factors that most influence its development. Evidence indicates that adequate PF values are considered important for people's health as they are related to better cardiovascular, skeletal, and mental health, which is why PF is considered an important component of a healthy lifestyle. On the other hand, there is body composition, which is responsible for quantifying, determining relationships and defining the quantitative changes of the different components of the human body. Its study is important to understand the effect of environmental factors such as growth, diet, diseases and physical exercise on the body. Research that has studied the effects of physical activity interventions aimed at improving PF indicates that they lead to improvements in people's body composition, specifically, reductions in fat and increases in muscle mass. This is beneficial for health, since a greater accumulation of fat in regions such as the waist and abdomen increases the risk factor for the development of metabolic diseases and insulin resistance, while adequate muscle mass values are associated with improvements in the metabolism of hepatic, pancreatic, and immune tissue, among others. Despite ample evidence exposing the health benefits, more than a quarter of adults worldwide are physically inactive. Among the factors that explain this behavior is that the practice of physical exercise is considered boring and difficult, which together with long working hours, keeps people away from the practice, which added to factors such as lack of motivation, family and social support, nearby sports environments and habits of practicing physical activity, generate negative attitudes towards physical activity, which leads to not practicing it. All of the above increases in university students, a complex population, due to the influence of bad healthy habits as a result of the impact of the academic load, the change from school life to university life and all university obligations. A tool that could be useful to eliminate the barriers described for not practicing physical activity can be immersive virtual reality (IVR), which is characterized by being a technique where a person, through the use of a screen mounted on the head, receives images, sounds and tactile sensations from a simulated world. all through an avatar that allows movements to be shown in a way that is consistent with the subject's body in a first-person perspective, making participants adjust their real actions in response to the observed movements of the avatar, driven by the illusory sensation of having the avatar's body, which generates measurable motor and physiological responses in the real body. In this sense, the RVI allows us to experience situations that, in reality, due to the necessary time or space, would not be possible. Several studies have analyzed the benefits of IVR in the field of public health, allowing greater effectiveness in the work of repetitive tasks, graphic and acoustic feedback, and adherence to physical therapies. This has been reflected in several studies that describe the effects of programs implemented through IVR in the rehabilitation of patients with cardiovascular accidents, Parkinson's, fibromyalgia and obstructive pulmonary diseases, among others. Regarding the area of physical exercise, the evidence places it as a tool that encourages healthy behaviors and the practice of physical activity, increasing adherence to exercise in the long term. A recent scoping review established that its use stimulates moderate and vigorous intensity levels, which could contribute to meeting physical activity recommendations, while other studies conclude that practicing physical exercise through IVR causes moderate and vigorous intensity physical activity, which are the ones that bring health benefits. On the other hand, there is information that indicates that performing physical activity through IVR generates a high level of enjoyment in participants, greater calorie burning, greater concentration and the feeling of being able to continue exercising for longer. Taking into account that the practice of physical exercise in the adult population is low, even more so in the university population, the IVR could be an alternative way to overcome the limitations that prevent the practice of physical exercise in adults. In addition, if the use of this technology generates enjoyment in those who use it and contributes to complying with the recommendations for physical activity, it is logical to think that a physical exercise program executed through IVR could contribute to improving PF and reducing body fat values and increasing muscle mass. However, the available evidence has not found information describing the effects of running exercise programs through IVR on physical fitness, nor the fat and muscle components of body composition. This study will provide useful information for this emerging line of research. It is hypothesized that the physical exercise program carried out through immersive virtual reality will cause improvements in physical condition and body composition in university adults. The objective of this randomized controlled trial is to evaluate the effect on physical fitness and body composition of a physical exercise program performed through immersive virtual reality in university adults.
