Behavioral and subjective measures capture performance and perceived workload but provide limited insight into the underlying neurocognitive adaptation. This study proposes and validates a synthetic EEG-derived cognitive training index (CTI) that integrates multiple training-sensitive neurometrics into a single composite metric, with two aims: to validate CTI as an objective marker of training progression in a physical training group, and to test whether VR-based training leads to neurocognitive adaptation comparable to physical training when participants subsequently execute the task in the real environment.\n                    <jats:italic>Approach.<\/jats:italic>\n                    Participants completed three repetitions of a realistic confined-space industrial maintenance procedure structured into Entrance, Rolling shutter, and Pipe replacement phases. Behavioral outcomes (execution time, procedural errors) and subjective workload NASA Task Load Index (NASA-TLX) were collected after each trial. Wearable EEG was recorded continuously; six neurometrics were computed from cleaned EEG using band-specific Global Field Power over predefined electrode sets. CTI was obtained via principal component analysis applied at the trial level to the multivariate neurometric time series, followed by segment-wise analysis. Temporal specificity of CTI was assessed through phase-randomized surrogate-data analyses.\n                    <jats:italic>Main results.<\/jats:italic>\n                    Execution time decreased across trials (\n                    <jats:italic>F<\/jats:italic>\n                    = 14.82,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; .001,\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    <jats:italic>p<\/jats:italic>\n                    = 0.35), procedural errors decreased similarly (\n                    <jats:italic>F<\/jats:italic>\n                    = 10.31,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; .001,\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    <jats:italic>p<\/jats:italic>\n                    = 0.27), and NASA-TLX declined (\n                    <jats:italic>F<\/jats:italic>\n                    = 11.94,\n                    <jats:italic>p<\/jats:italic>\n                    &lt; .001,\n                    <jats:italic>\u03b7<\/jats:italic>\n                    <jats:sup>2<\/jats:sup>\n                    <jats:italic>p<\/jats:italic>\n                    = 0.30).
