Abstract Cardiorespiratory fitness is known to protect against cognitive decline in older adults. Specifically, it has been shown that physical activity and are beneficial for executive functions crucial independent living up old age. In this study, 115 individuals aged 80 years underwent a cardiorespiratory assessment using the two-minute step test had their electroencephalogram recorded during colored flanker task order measure function performance. was related quicker responses task. A mediation analysis carried out determine whether these positive effects were mediated through event-related potentials (N1, N2, or P3) motor-related cortical (MRCP). better visual discriminative processing as indicated by larger occipital N1 amplitudes. addition, associated with MRCP amplitudes, which correlate of response generation process. Fitness not found have significant effect on fronto-central N2 parietal P3, thought capture control processes such conflict detection inhibition. Moreover, all reported present three trial conditions (congruent, neutral, incongruent). Thus, results indicate times fitter people motor rather than control.

Background Rumination, thought to be induced by stressful events, is a pivotal factor contributing cognitive vulnerabilities in stress-related disorders. Previous studies have demonstrated an association between the prefrontal cortex and stress. However, functional connectivity of high ruminators during stress not fully understood. Methods 28 trait rumination group (HTR) 22 low (LTR) were recruited. Each participant underwent both Trier Social Stress Test (TSST) control task long-arm crossover design, while collecting near-infrared spectroscopy data. We analyzed static dynamic FC (DFC) under two different conditions then compared difference HTR LTR. Results induction procedure was highly successful Analysis on (SFC) showed that LTR exhibited marked increase SFC TSST, comparatively lesser increase. Further analysis DFC, prefrontal-based DFCs higher TSST with condition, but these patterns HTR. But variability DFC left IFG MFG related state rumination. Conclusion Current study may shed light aberrant pattern underlying its research this area elucidate specific mechanisms are impaired their impact emotional regulation psychological well-being.
