New poster using fNIRS Cortivision in sports

Nov 6, 2023Science

The use of near-infrared spectroscopy in the areas of mobility, accessibility, and integrability has increased significantly in recent years (Herold et al., 2018). These include activities that are related to cycling, running, and dancing. Investigating the effects of physical activity on cognitive functioning using fNIRS finds its unique application in the study of human cognition in motion.

A group of researchers from Poland used the fNIRS Photon Cap device to investigate the effects of HIE on executive function among elderlies, focusing on the neuronal substrate (Skurewicz et al., 2023).




The researchers studied a group consisting of healthy, physically inactive 16 seniors whose age were over 65 years. FNIRS was used on areas of the dorsolateral prefrontal cortex and medial frontal gyrus.


Fig 1. Experimental protocol: experiment consisted of two sessions, control (CTL) and high-intensity interval excercise (HIE) separated by at least one week.


The experiment consisted of two sessions, control (CTL) and high-intensity interval exercise (HIE), separated by at least a week. Each session was conducted, in a randomized and balanced manner, with half of the participants starting with the session with HIE. 

The HIE protocol consisted of eight 60-second cycles at 90% VAT, corresponding to ~90 HR of maximum intensity and a 30-second rest.


HIE contributed to a significant, shorter execution time in the TMT-B test. Moreover, an increased prefrontal activation (DLPFC and MFG) has been observed following an acute bout of HIE.

The researchers indicate that the results suggest that the proposed HIE protocol can effectively improve executive function among older people. The increased prevalence of cognitive impairment makes there an urgent need for comprehensive research to elucidate the effects of targeted exercise interventions on improving cognitive function.
