The SUSU Sport Science Research Centre has launched a research study that for the first time in Russian practice will conduct a comprehensive medical and biological evaluation of phygital loads: hybrid competition impact, where physical activity of athletes is inextricably bound with digital environment. The object of this study is table tennis using augmented reality glasses (VR table tennis). Qualified practicing table tennis players acted as the experiment participants.
The key question that the scientists try to answer is whether a phygital match causes the same physiological and psychophysiological body reaction as a real game does. To answer it, the researchers need to simultaneously control a multitude of parameters: from central hemodynamics to cognitive information processing rate.
During the examination, sensors are put on athletes to record their heart rate and heart rate variability. These indicators allow to assess how much the cardiovascular system gets engaged during a virtual match, and whether the player reaches the training heart rate zones, and how the vegetative nervous system balances between the sympathetic and parasympathetic responses. Namely the heart rate variability is a sensitive indicator of whether the body feels phygital load as a real physiological stress or as a neutral sensory flow.
At the same time, the scientists measure the reaction speed: whether the table tennis player manages to read the digital ball trajectory and make decisions with no loss in the hitting quality. There are significantly more visual stimuli in a VR helmet as compared to a real game, and this creates high cognitive load for the visual analyser and for paying attention. The question is whether the brain compensates for this excessiveness, or reduces the precision of locomotor response. The results will allow to assess the psychophysiological value of the phygital mode for athletes.
A separate block of the research study is devoted to the vestibular function and the postural control. During a phygital match, athlete’s eyes track the virtual trajectory of the ball, while his/her feet stand on a real surface: the vestibular system receives discordant sensory input. The scientists check whether the posture stability and the movements quality are preserved in this sensory conflict. The results will help understand how safe phygital loads are for the locomotor system, and how the training process should be corrected.
“If we confirm our hypothesis, then this research study for the first time will present an objective physiological and psychophysiological mapping of phygital loads: with quantitative values of the heart rate variability, reaction speed and postural stability,” comments Director of the Sport Science Research Centre Olga Makunina. “This opens up several applied fields. Graduated loads: based on the indicators of a certain player, the virtual sparring intensity may be selected according to his/her current functional state – just the way it is done in classical training. Safe simulation of the competition stress: digital environment allows to generate the physiological response comparable to a tournament finals, with no injury risks for joints and muscles. Biomechanical analytics: recording each micromove of the tennis racket provides data for a detailed technique analysis, what is not possible in real-world conditions. Cognitive monitoring: controlling the reaction speed in the phygital mode allows to trace the dynamics of attention and focus – it is extremely difficult to measure these indicators in an ordinary match.”
This research study is at the intersection of sports medicine, physiology, psychophysiology, and engineering. Its results will allow to give scientific substantiation to the introduction of phygital tools to the training process based not on intuition, but on strict indicators of the cardiovascular, vegetative, cognitive, and biomechanical diagnostics. Such a trendy technology is no longer an entertainment, it becomes a full-fledged chapter in sports science.
