Boost your brainpower

If you want to keep your brain sharp and healthy, you need to know about brain-derived neurotrophic factor (BDNF). Discover how HIIT can unlock the power of BDNF and boost your cognitive performance.

What is BDNF?

Brain-derived neurotrophic factor (BDNF) is a molecule that plays a crucial role in keeping your brain healthy and young. BDNF protects brain cells from damage due to injury, disease, or aging. It also promotes synaptic plasticity and helps our brain to change and adapt which is crucial for learning and memory.

Research shows that higher plasma BDNF levels are associated with better cognitive performance, attention, and spatial memory, whereas low plasma BDNF levels are found in patients with conditions such as dementia, mild cognitive impairment, Alzheimer’s disease, and major depression.

The benefits of exercise for BDNF

One way to increase BDNF is through exercise. The hormetic stress created during physical activity stimulates the production of BDNF in our bodies, with greater increases in BDNF levels being reported at higher exercise intensities.

The benefits of HIIT for BDNF levels have been reviewed in a meta-analysis of 15 studies, which demonstrated moderate acute and large chronic effects for the increase in plasma BDNF levels through HIIT in healthy young individuals.

Exercise stimulates the production of BDNF in our bodies, a molecule that plays a crucial role in keeping your brain healthy and young.

Greater increases in BDNF levels were reported at higher exercise intensities, according to a study.
