The Claim
Changes in serum BDNF levels are not significantly correlated with changes in cognitive performance following acute maximal exercise in healthy young adult males, indicating that BDNF does not directly mediate the observed memory improvements.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
After intense exercise, changes in BDNF levels in the blood do not align with changes in memory performance in healthy young men, meaning BDNF is not directly responsible for the memory changes seen after exercise.
See the scientific wording
There is no significant correlation between changes in serum BDNF levels and changes in cognitive performance following acute maximal exercise in healthy young adult males, suggesting BDNF is not a direct mediator of the observed memory improvements.
After intense exercise, the brain improves memory through changes in nerve cell connections and signaling, even when the level of BDNF in the blood does not change in a way that matches the memory gain.
What the research says
1 studyStudy: Acute exercise increases BDNF and short-term memory in healthy adults.
After a tough workout, healthy young men had more BDNF in their blood and better memory, but the amount of BDNF didn’t predict how much their memory improved — so BDNF alone can’t explain why memory got better.
