Key result
Differences in peak oxygenated hemoglobin, area under the curve, and slope between the left and right prefrontal cortex during moderate exercise significantly correlated with reaction time changes.
Why the study?
Prefrontal cortex oxygenated hemoglobin concentration changes relate to cognitive function, but the effect of differences between left and right prefrontal cortex levels after exercise was unclear.
Does moderate-intensity aerobic exercise affect cognitive function in relation to differences in oxygenated hemoglobin concentration in the left and right prefrontal cortex in healthy male college students?
Population

Comparison
Pre-exercise vs post-exercise vs 20 min post-exercise rest
Follow-up

Prefrontal O2Hb asymmetry during moderate exercise was associated with reaction time changes in healthy males; hypothesis-generating and should not yet change practice.
Does moderate-intensity aerobic exercise affect cognitive function in relation to differences in oxygenated hemoglobin concentration in the left and right prefrontal cortex in healthy male college students?
Differences in oxygenated hemoglobin concentration between the left and right prefrontal cortex during moderate-intensity aerobic exercise are significantly correlated with changes in cognitive reaction time.
Qin et al. (2021) studied Healthy (n=12). Moderate-intensity aerobic exercise was evaluated on Correlation between changes in post-exercise reaction times (2-back cognitive test) and differences in O2Hb levels (L-PFC minus R-PFC). Differences in peak oxygenated hemoglobin, area under the curve, and slope between the left and right prefrontal cortex during moderate exercise significantly correlated with reaction time changes.
