Overview

Systematic review analyzes exercise impacts on brain-derived neurotrophic factor in adolescents, suggesting vigorous activities boost levels.

Key Points

  • MAIN FINDING: Exercise positively influences brain-derived neurotrophic factor levels in adolescents, but results are inconsistent.
  • KEY EVIDENCE: Of the 8 trials reviewed, 4 showed significant BDNF increases with high-intensity exercise lasting 6 weeks or more.
  • APPROACH: The systematic review followed PRISMA guidelines and included various exercise modalities and quality assessments.
  • SIGNIFICANCE: Understanding exercise's impact on BDNF can inform interventions for enhancing adolescent neurodevelopment.
