The Claim
A single session of maximal incremental cycling increases serum brain-derived neurotrophic factor (BDNF) levels 24 hours post-exercise in healthy young adult males, with no significant change observed at 15 minutes post-exercise.
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 one intense cycling session, healthy young men show higher levels of brain-derived neurotrophic factor in their blood 24 hours later, but not 15 minutes after exercising.
See the scientific wording
A single session of maximal incremental cycling increases serum brain-derived neurotrophic factor (BDNF) levels 24 hours post-exercise in healthy young adult males, with no significant change observed at 15 minutes post-exercise, suggesting a delayed neurochemical response to intense aerobic activity.
After intense cycling, muscles and blood platelets release a brain-growth protein slowly over many hours, causing its levels in the blood to rise 24 hours later but not right after exercise.
What the research says
1 studyStudy: Acute exercise increases BDNF and short-term memory in healthy adults.
After a tough bike ride, healthy young men had more of a brain-growth chemical in their blood 24 hours later — but not right after exercising. This means the body takes time to respond.
