“…Accordingly, the findings are unlikely to be applicable to other forms of physical activity with different durations and performed at different intensities. Different exercise modalities and complexities would naturally elicit distinct patterns of brain connectivity, and, as a consequence, the results of the present study cannot be extrapolated to all physical tasks (Brümmer et al, 2011;Büchel et al, 2023). Fourthly, one of the most important limitations of the present study is the use of a questionnaire to divide the sample into groups in accordance with their tolerance profiles.…”

The main objective of this study was to further understanding of the patterns of spectral connectivity during exercise in low‐ and high‐tolerant individuals. Thirty‐nine healthy individuals (i.e., 17 low‐ and 22 high‐tolerant participants) took part in the present study. A state‐of‐the‐art portable electroencephalography system was used to measure the brain's electrical activity during an incremental exercise test performed until the point of volitional exhaustion on a cycle ergometer. Spectral coherence was used to explore the patterns of connectivity in the frontal, central, and parietal regions of the brain. Physiological, perceptual, and affective responses were assessed throughout the exercise bout. The spontaneous eyeblink rate was also calculated prior to commencement and upon completion of the exercise trial as an indirect assessment of the dopaminergic system. The present findings indicate that high‐tolerant individuals reported lower levels of perceived activation, especially during the preliminary stages of the exercise test. Participants in the high‐tolerance group also reported greater levels of remembered pleasure upon completion of the exercise test. The data also revealed that high‐tolerant individuals exhibited increased connectivity of theta waves between frontal, central, and parietal electrode sites and increased connectivity of beta waves, primarily within the parietal cortex. Correlational analysis indicated the possibility that low‐ and high‐tolerant individuals make use of different neural networks to process and regulate their psychophysiological state during exercise‐related situations. This strategy could potentially represent a conscious decision to downregulate affective arousal and facilitate the neural control of working muscles during situations of physical stress.
