Methods: In this preliminary study, a single-group, repeated-measures design was employed. Twelve elite skateboarders completed a 6-week sprint interval training (SIT) program. Mental fatigue was assessed at three time points\u2014pre-intervention (Week 0), mid-intervention (Week 3), and post-intervention (Week 6)\u2014using a standardized 60 min Stroop task, with post-task EEG, HRV, and VAS measures collected to characterize neurophysiological and subjective responses. Results: Across the intervention, EEG indices indicated higher central nervous system activation and more stable post-task neural profiles. HRV indices suggested more flexible autonomic regulation, with favorable changes in low- and high-frequency components, sympathovagal balance, and recovery-related scores, whereas baseline-related indices such as RMSSD and SDNN showed no clear change. VAS ratings showed stable MF, accompanied by increased mental exertion and motivation and reduced physical fatigue over time. Conclusions: These preliminary findings suggest that a 6-week SIT program may be associated with enhanced resistance to Stroop-related MF in elite skateboarders, potentially through coordinated adaptations in neural activation, autonomic regulation, and psychological factors. Future randomized studies incorporating behavioral performance and sport-specific cognitive tasks are warranted to confirm and extend these observations.<\/jats:p>","DOI":"10.3390\/life16010025","type":"journal-article","created":{"date-parts":[[2025,12,24]],"date-time":"2025-12-24T09:58:34Z","timestamp":1766570314000},"page":"25","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Effects of Sprint Interval Training on Brain Fatigue Resistance in Competitive Skateboarders: Evidence from EEG, HRV, and VAS Measures"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8421-8442","authenticated-orcid":false,"given":"Mulin","family":"Yang","sequence":"first","affiliation":[{"name":"Physical Fitness Training Research Center, China Institute of Sport Science, Beijing 100061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-7709-7522","authenticated-orcid":false,"given":"Yuqiang","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Physical Education, Shanghai University of Sport, Shanghai 200438, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5394-162X","authenticated-orcid":false,"given":"Kewei","family":"Zhao","sequence":"additional","affiliation":[{"name":"Physical Fitness Training Research Center, China Institute of Sport Science, Beijing 100061, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Fouillot, C., Sauli\u00e8re, G., Antero, J., Sedeaud, A., and Toussaint, J.F.
