Time to add another benefit to the list for high intensity interval training (HIIT).
Researchers at the Autonomous University of Baja California have been doing some work to understand the effect of this type of training on the brain, and performing a meta-analysis of research and experiments done in the field.
They published their findings recently.
They found that brain-derived neurotropic factor (BDNF) is responsive to exercise, especially the short and intense variety.
BDNF can be thought of as fertilizer for the brain. We also know that BDNF plays a huge role in neurogenesis, as well as improving and maintaining cognitive function.
Long-term, BDNF is likely a major defender against Alzheimer's disease and depression.
The long story short version of the research is this: high intensity intervals are good for your body, body composition, and even your brain.
Don't skimp on them.
