PURPOSE: This preliminary study examined the associations between a 6-week sprint interval training (SIT) program and mental-fatigue (MF) related neurophysiological and subjective indicators in elite skateboarders.
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-pre-intervention (Week 0), mid-intervention (Week 3), and post-intervention (Week 6)-using 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.
