Cognitive functions and skill level in Brazilian Jiu-Jitsu: an exploratory study using virtual reality

Professionals appeared to score higher in accuracy-related measures and showed slower reaction times; however, these patterns should be interpreted as preliminary trends rather than evidence of differences in underlying mechanisms or strategic prioritization. Given the very small sample size and the exploratory nature of the study, no conclusions can be drawn about underlying cognitive mechanisms. The findings suggest preliminary, unstable patterns between expertise levels in selected cognitive measures; however, given the small sample size and exploratory design, no causal inferences regarding the influence of experience on cognitive functions can be drawn. The study also suggests that VR may have potential as an assessment tool, though its utility for evaluating BJJ-specific cognitive performance remains unvalidated and should be considered exploratory at this stage.
