Why the study?

Most existing fNIRS studies are cross-sectional without exercise interventions, leaving the causal relationship between exercise and brain functions elusive.

Do exercise interventions improve brain functional activity in healthy individuals?

Population

Healthy individuals across 29 included studies

Comparison

Exercise interventions vs not specified

Design

Systematic review

Overview

May support exercise for cognitive health via cortical hemodynamics; extends mechanistic evidence from systematic review.

Structured PICO

Do exercise interventions improve brain functional activity in healthy individuals?

P
Population
Healthy individuals (29 studies included in systematic review)
I
Intervention
Exercise interventions utilizing large muscle groups of the whole body
O
Outcome
Alterations in brain functional activity (cerebral cortical blood flow changes assessed using fNIRS)surrogate

Exercise interventions alter oxygenated hemoglobin levels in the prefrontal and motor cortices, suggesting a hemodynamic mechanism for exercise-induced improvements in cognitive function.
