Assessment of the intensity and attractiveness of physical exercise while playing table tennis in an immersive virtual environment depending on the game mode

Abstract Background It appears that active video games (AVGs) and training apps that allow for physical activity (PA) in immersive virtual reality (VR) may be useful for sports, health-enhancing PA, and physical education (PE). Therefore, research is needed to identify their potential. Objective The study aimed to evaluate the intensity and attractiveness of exercise during table tennis (TT) training in VR in arcade and simulation modes and to assess the potential for using such exercises in health-enhancing PA, sport, and PE. Methods The research used the Racket Fury: Table Tennis VR. Exercise intensity during TT training in VR was evaluated by heart rate (HR) monitoring and rating of perceived exertion (RPE 6–20). The effectiveness of short-term TT training in VR was estimated based on the user’s performance in playing against an opponent with artificial intelligence (AI), satisfaction with playing TT was measured using the Physical Activity Enjoyment Scale (PACES), and the potential usefulness of the tested app in PA, sport, and PE was assessed based on a questionnaire for participating PE teachers (30 participants). Results PA intensity during TT training in VR expressed as a percentage of maximum heart rate (HR max ) was moderate but was significantly ( p < 0.001; d=-0.830) higher in the easier arcade mode (69.50 ± 12.58%HR max ) than in the simulation mode (64.10 ± 9.67%HR max ). Despite the greater fatigue of respondents, user satisfaction was significantly higher in arcade mode. Users’ performance when playing with AI was significantly better after 20 min of training in VR than before training. PE teachers recognize the great potential of the app. Conclusions The application tested is characterized by a beneficial PA intensity, with its level depending on the game mode. Facilitating strokes during a game of virtual TT promotes increased intensity of exercise and increased enjoyment of the PA. Short-term TT training in VR improves playing skills in a virtual environment. PE teachers spoke highly of the app and recognized the potential for using VR technology in PA, sports, and school PE.
