In light of growing evidence regarding the impact of mental fatigue on sport performance, this study investigates the potential of self-selected music to modulate neurophysiological and behavioral changes that emerge during cognitively demanding tasks. Although previous research indicates that music can influence emotional regulation and arousal levels, findings on its capacity to mitigate mental fatigue during high cognitive load remain limited. Therefore, the aim of this study was to evaluate the effects of self-selected music on Stroop task–induced mental fatigue through EEG band power, subjective fatigue ratings, and basketball free-throw performance. A total of 24 male basketball players aged 18–25 were randomly assigned to music and non-music groups, and pre/post EEG recordings, subjective fatigue scores, and free-throw performance were collected. Linear mixed-effects analyses revealed a significant time effect in the Alpha band under Eyes Open conditions across frontal, fronto-central, central, centro-parietal, parietal, and parieto-occipital regions (p < .05), with the most pronounced increase observed in the frontal region (p < .001). Significant decreases were found in the Beta band within parietal and temporal regions (p = .012). Subjective fatigue scores demonstrated a significant main effect of time (p < .001), whereas group and interaction effects were not significant (p = .378; p = .097). No significant effects were detected for free-throw performance (p > .25). These findings indicate that self-selected music does not substantially modulate cortical fatigue processes arising under high cognitive load and exerts limited influence on well-automated motor skills.

This study aimed to investigate differences in attentional orienting among combat sport athletes, closed-skill athletes, and sedentary individuals using the Posner cueing paradigm, with reaction time and response accuracy examined as behavioral indices of attentional orienting. A total of 97 participants aged 18–25 years were classified into three groups: closed-skill athletes (n = 30), combat sport athletes (n = 35), and sedentary individuals (n = 32). Cognitive performance was assessed through the Posner cueing task, which included 100 trials comprising valid and invalid cue conditions. Reaction time in valid (RTvalid) and invalid (RTinvalid) trials, along with response accuracy (Racc), were analyzed using one-way ANOVA and Bonferroni post-hoc tests. The results revealed no significant group differences in RTvalid or RTinvalid. However, a significant difference emerged for Racc values (p = 0.013). Closed-skill athletes demonstrated significantly higher accuracy than combat sport athletes, while sedentary individuals showed intermediate performance. These findings suggest that accuracy-based indicators—rather than reaction time—more effectively distinguish cognitive performance among combat, closed-skill, and sedentary groups, with closed-skill athletes demonstrating a clear advantage in attentional orienting. Future research should investigate these group-specific differences using longitudinal and multi-component cognitive designs to more precisely determine how varying sport demands contribute to the development of attentional efficiency over time.

Resting-state EEG oscillations provide insights into neurophysiological adaptations associated with physical activity and sport specialization. This study examined spectral power density (PSD), peak alpha frequency (PAF), and phase slope index (PSI) differences among sedentary individuals, individual sport athletes, and team sport athletes under eyes-open (EO) and eyes-closed (EC) conditions. EEG data were collected from Fp1, Fp2, T7, T8, O1, O2, and Pz locations, focusing on theta, alpha, and beta frequency bands. Results indicated no significant differences in PAF across groups (p>.05). However, PSD analyses revealed group-specific modulations: individual athletes exhibited elevated theta power at temporal (p= .002; η²= .2988) and parietal (p= .0024; η²= .3244) sites compared to sedentary, while team athletes showed reduced theta power at frontal (p= .028; η²= .1834) and occipital (p= .019; η²= .1978) regions. Alpha power was higher in sedentary participants at temporal and parietal sites during EC (p

The aim of this study was to examine the effects of music played at 432 Hz and 440 Hz on brain electrical activity, considering the specialization in music. The study included 11 non-musicians and 10 musicians, with participants completing two sessions, 24 hours apart. In the first session, participants listened to the 432 Hz Samuel Osmond Barber “Adagio for Strings Op. 11” and the 440 Hz Petrovich Mussorgsky “Night on Bald Mountain” compositions. In the second session, the 440 Hz “Adagio for Strings Op. 11” and the 432 Hz “Night on Bald Mountain” were performed. Brain electrical activity was assessed using coherence and Power Spectral Density (PSD) methods. The results revealed differences in brain electrical activity between musicians and non-musicians when listening to music at different frequencies. In the PSD analysis, a two-way ANOVA showed a significant group effect (p < 0.05; ηp2=0.086) in the O1 channel within the theta frequency. Post hoc Tukey HSD tests revealed that O1 theta values were higher in musicians. Additionally, a significant frequency effect was observed in the Pz channel within the theta frequency (p

Technological advancements in neuroscience have provided many conveniences to scientists, researchers, and consumers. The emerging electroencephalography (EEG) devices is a good example for it. The objective of this study was to investigate the validity and reliability of a new wireless EEG device Mentalab Explore for resting-state EEG (rsEEG) recordings in eyes open and eyes closed conditions. Twenty-three healthy subjects were recruited for the study. The subjects visited the laboratory on two occasions. On the first day, both devices were used to record rsEEG data, and after 24 hours, only the Mentalab Explore was used to record rsEEG for test-retest reliability analysis. We compared the alpha peak frequency, suppression, and mean power between the two devices. Intraclass correlation coefficient was calculated for testretest reliability analysis. There were no significant differences in alpha peak frequency or suppression between the clinical-grade and the new devices for O1 and O2 channels in eyesclosed condition. The two measurements completed ∼24 h apart using the Mentalab system were similar for all the variables. There were also significant correlations between the devices and test-retest measurements for alpha peak frequency, suppression, and power. We showed that the consumer-grade Mentalab Explore with gel electrodes is a reliable and valid EEG recording device for rsEEG spectral features.
