Ruler Drop Method in Virtual Reality as an Accurate and Reliable Tool for Evaluation of Reaction Time of Mixed Martial Artists

Reaction time (RT) is one of the key factors in combat sports. Its high level a predictor sporting success. Therefore, RT tests are an important diagnostic tool The implementation some conventional psychomotor virtual settings can facilitate research and improve objectivity standardization measurement procedure. main aim present study was to evaluate reliability validity measurements, using ruler drop method (RDM) implemented within immersive reality (VR). Twenty-eight professional mixed martial arts (MMA) fighters were examined. new VR estimated by comparing results obtained computer test catch-the-ruler test. measurements evaluated intraclass correlation Analysis variance used examine differences MMA from different tests. Significant correlations found between other tests, with highest values observed performed environment computer-based ICC coefficients for all reaction conducted group at adequate or level. analysis showed that differed significantly In times longer than during RDM measurements. did not depend on hand conclusion, allows designing conducting valid reliably objectively, standard testing procedures, while reducing effect human results.
