Effects of Virtual Reality-based Cognitive and Technical Drills on Scanning and Passing Performance in Youth Football Players: a Randomized Controlled Study
In recent years, virtual reality (VR) has emerged as a promising tool to bridge this gap. By providing immersive, interactive, and customizable environments, VR-based interventions offer a safe and controlled platform for simulating complex game scenarios (7). From a neurophysiological perspective, VR training can stimulate the activation of key brain regions involved in perception, attention, and decision-making (8). Recent research examined the relationship between perceptual-cognitive performance in a dynamic 360° environment and soccer-specific performance in youth players (9). Their findings indicated a significant positive correlation between performance in a 360° multiple object tracking task and both passing accuracy and defensive effectiveness in small-sided games.
The repeated exposure to dynamic, visually rich stimuli enhances selective attention, working memory, and anticipatory skills, which are all critical for effective environmental scanning (10,11). Furthermore, the real-time feedback and motor engagement involved in VR-based drills promote sensorimotor integration, strengthening the neural pathways that support technical execution, such as passing accuracy and timing (12). These findings suggest that VR is not merely a visual aid but a cognitive training modality capable of eliciting measurable changes in sport-specific decision-making and technical performance (13).
However, current literature is still limited in terms of randomized controlled trials investigating the combined effects of VR on scanning and passing performance in football players. Therefore, this study aimed to evaluate the effects of a VR-based training program that integrates cognitive and technical drills on scanning behavior and passing performance in youth footballers. It was hypothesized that VR-based training intervention would demonstrate significantly greater improvements in scanning frequency and passing accuracy compared to those in the control group receiving only traditional training.
The present parallel-group randomized controlled trial was designed to investigate the effects of a 7-week VR-based training program on scanning behavior and passing performance in youth football players. A total of 22 male athletes from U16-U17 categories were recruited from a regional football academy. Inclusion criteria required participants to be injury-free in the last 12 months, possess normal or corrected-to-normal vision, and have no prior exposure to VR training. Players with neurological or vestibular disorders, or recent orthopedic surgery, were excluded. Participants and their legal guardians provided informed consent prior to participation.
Participants were randomly assigned (1:1) to either the VR training group (n = 11) or a control group (n = 11). Randomization was stratified by age and playing position to ensure group equivalence. The control group continued their regular football training program, while the VR group participated in an additional VR training intervention delivered via the SensiballVR™ platform three times per week for seven weeks (21 sessions in total). Each VR session targeted two core domains: (1) scanning frequency through tasks requiring frequent and purposeful exploration of the virtual pitch, and (2) technical passing performance through drills simulating teammate and opponent interactions under time pressure. The VR system incorporated HTC Vive Pro Eye headsets and patented haptic footwear technology, providing tactile feedback and precise motion tracking to ensure ecological validity. Training intensity was progressively increased across three phases, from basic visual exploration to advanced dual-task drills with complex passing demands.
Outcome measures included (a) scanning frequency classified as before ball reception, during control, and off-the-ball actions, and (b) passing performance categorized by execution type (one-touch, control-pass, multi-touch), outcome (successful or unsuccessful), and style (short, penetrative, long). All data were collected during structured small-sided games (5v5+1 and 7v7+7 joker formats) and analyzed via synchronized aerial and ground-level video recordings. Notational analysis was conducted by two independent analysts with excellent inter-rater reliability (ICC > 0.90).
Statistical analyses were performed using non-parametric tests due to violations of normality in several variables. Within-group changes were assessed using the Wilcoxon signed-rank test, while between-group comparisons of delta scores (post-pre) were evaluated using the Mann-Whitney U test. Effect sizes (r) were calculated and interpreted using conventional thresholds. Percentage changes in mean values were also reported to illustrate practical relevance.
