What is the Origin of Exercise Induced Neuroplasticity?

This concept is a modern integration of exercise physiology and neuroscience, moving beyond the historical view of exercise as purely musculoskeletal. The term 'neuroplasticity' itself, meaning the brain's ability to reorganize itself, gained prominence in the late 20th century. The recognition that exercise is a powerful, non-pharmacological modulator of brain structure solidified the specific term 'Exercise Induced Neuroplasticity.'

What is the Mechanism of Exercise Induced Neuroplasticity?

The primary mechanism involves physical exertion stimulating the release of brain-derived neurotrophic factor (BDNF) from muscle tissue and the brain. BDNF acts as a potent fertilizer for the brain, promoting the survival of existing neurons and encouraging the growth of new synapses and neurons, particularly in the hippocampus, an area critical for memory. Furthermore, exercise improves cerebral blood flow and modulates the release of neurotransmitters like serotonin and dopamine, directly influencing mood and stress resilience.

Exercise Induced Neuroplasticity

Meaning

Exercise Induced Neuroplasticity refers to the measurable structural and functional changes in the brain and nervous system that occur as a direct result of physical activity. This physiological phenomenon includes the creation of new neural connections, enhanced synaptic strength, and the increased production of neurotrophic factors. It is a critical mechanism by which physical movement supports cognitive health, mood regulation, and hormonal balance.
