Association of Cardiovascular Risk Markers and Fitness with Task-Related Neural Activity during Animacy Perception

Abstract

Purpose: Numerous studies have demonstrated the association between cardiovascular risk markers and fitness, and broad aspects of cognition; however, the possible association of cardiovascular risk markers and fitness with social cognition, which plays a significant role in the development and maintenance of social relationships, has largely been ignored. Herein, we investigated the relationship of cardiovascular risk markers and fitness with task-related neural activity during animacy perception. Methods: We analyzed data from the Human Connectome Project derived from 1027 adults age 22-37 yr. Canonical correlation analysis (CCA) was conducted to evaluate the association between participants' body mass index, systolic and diastolic blood pressure, submaximal endurance, gait speed, hand dexterity, and muscular strength with task-related neural activity during animacy perception. Results: We observed a single significant CCA mode. Body mass index and blood pressure demonstrated negative cross-loadings with task-related neural activity in the temporoparietal, superior and anterior temporal, posterior cingulate, and inferior frontal regions, whereas submaximal endurance, hand dexterity, and muscular strength demonstrated positive cross-loadings. The observed CCA variates did not seem highly heritable, as the absolute differences in CCA variates in monozygotic twins, dizygotic twins, and nontwin siblings were not statistically different. Furthermore, the cardiovascular risk markers and fitness CCA variates were positively associated with animacy perception and emotion recognition accuracy, which was mediated by the task-related neural activity. Conclusions: The present findings can provide new insights into the role of markers for cardiovascular health and fitness, specifically their association with social cognition and the underlying neural basis. The intervention for cardiovascular risk and fitness could be a potentially cost-effective method of targeting social cognition.

Uncovering the links between physical activity and prosocial behaviour: A functional near-infrared spectroscopy hyperscanning study on brain connectivity and synchrony

“…Third, our study focused primarily on the function of the LPFC; however, other regions involved in the empathy and mentalizing network, such as the temporal-parietal junction and posterior cingulate cortex, also contribute to human prosocial behaviour. 18 Recent findings suggest that exercise can enhance social brain network function, 65,66 thereby suggesting the role of these additional regions in this association. Future studies should incorporate other imaging methods, such as fMRI, to explore the involvement of these regions.…”

The Nervous System as a Pathway for Exercise to Improve Social Cognition

“…This is supported by cross-sectional findings showing that higher aerobic fitness in children and adults is linked with better emotion recognition and regulation ( 46 , 47 ). However, other aspects of physical fitness, such as muscle strength and hand dexterity, have also been related to this subdomain of social cognition ( 45 ). The role of aerobic fitness in particular is further underlined in an experimental study that focused on emotion regulation.…”

Trial Analysis of Brain Activity Information for the Presymptomatic Disease Detection of Rheumatoid Arthritis

“…Specifically, we used supervised multiview canonical correlation analysis (sMVCCA) [ 18 ], which is capable of handling multiple types of information. Subsequently, we calculated cross-loadings using features obtained from sMVCCA because this calculation is a powerful tool for revealing the potential relationships between biological information and other factors [ 19 , 20 , 21 ]. Thus, we identified important brain regions contributing to the classification of F759 and wild-type mice.…”
