Key result
Acute supramaximal exercise significantly increased prefrontal cortex oxygenation during a post-exercise cognitive task compared to pre-exercise levels, though cognitive performance scores did not significantly improve.
Why the study?
Does acute supramaximal exercise increase prefrontal cortex oxygenation during a cognitive task in healthy male volunteers?
Does acute supramaximal exercise increase prefrontal cortex oxygenation during a cognitive task in healthy male volunteers?
Absolute Event Rate: 7.32% vs 3.11%
p-value: p=<0.001
Acute supramaximal exercise increases prefrontal cortex oxygenation during subsequent cognitive tasks, with the magnitude of the hemodynamic response correlating with the individual's anaerobic peak power.

Hypothesis-generating for exercise effects on PFC oxygenation in healthy males; leaves open translation to performance or clinical use.
Bediz et al. (2016) studied Healthy volunteers (n=35). Acute supramaximal exercise (Wingate Anaerobic test) vs. Pre-exercise baseline was evaluated on Prefrontal cortex oxygenation (oxy-Hb) during 2-Back test in central PFC (p=<0.001). Acute supramaximal exercise significantly increased prefrontal cortex oxygenation during a post-exercise cognitive task compared to pre-exercise levels, though cognitive performance scores did not significantly improve.
