The Claim
In healthy young Japanese men, 30 minutes of moderate-intensity aerobic exercise at 60% VO2max does not produce a statistically significant group-level increase in serum BDNF levels, although 55% of individuals showed individual increases, suggesting population-specific variability in neurotrophic response to 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.
In healthy young Japanese men, 30 minutes of moderate-intensity aerobic exercise at 60% VO2max does not result in a statistically significant average increase in serum BDNF levels across the group, but 55% of individuals experienced individual increases.

A genetic variation in the BDNF gene prevents some people from releasing enough BDNF from their brain cells during exercise, so their blood BDNF levels do not rise even when others' do.
What the research says
1 studyIn a study of young Japanese men, biking at a moderate pace for 30 minutes didn’t raise BDNF levels on average, but about half of the guys did see an increase — meaning some people respond to exercise this way and others don’t.
