Shaping the adult brain with exercise during development: Emerging evidence and knowledge gaps

Area of Science:

• Neuroscience
• Developmental Biology
• Exercise Science

Background:

• Exercise positively impacts brain development, increasing neural components and enhancing cognition and stress resilience.
• While acute exercise benefits are well-documented, the long-term neural and cognitive effects of developmental exercise are less understood.
• Sedentary behavior in modern society raises concerns about its impact on brain development.

Purpose of the Study:

• To review the current literature on the long-term cognitive and neural effects of exercise during development.
• To identify knowledge gaps regarding how developmental exercise influences adult brain health and function.
• To explore the underlying mechanisms of plasticity driven by exercise in early life.

Main Methods:

• Systematic literature review of studies on exercise, brain development, and adult cognition.
• Analysis of evidence from human and animal models.
• Synthesis of findings on neural plasticity and cognitive outcomes.

Main Results:

• Developmental exercise is linked to lasting positive effects on brain structure and cognitive function into adulthood.
• Emerging evidence suggests exercise-induced plasticity during development has enduring benefits.
• Significant knowledge gaps remain in understanding the precise mechanisms and long-term consequences.

Conclusions:

• Exercise during development offers a promising avenue for promoting lifelong brain health and cognitive function.
• Further research is needed to elucidate the mechanisms by which developmental exercise shapes the adult brain.
• Addressing sedentary behavior is critical for optimizing brain development and function throughout the lifespan.
