Resistance Exercise Promotes Release of Neurotrophic Factors

TRAINING!, not exercise.

New research presented here at the American College of Sports Medicine 57th Annual Meeting shows that circulating levels of brain-derived neurotrophic factor (BDNF) increase after intense resistance training, which might explain why exercise is effective at protecting and improving brain function.

The incidence of neurodegenerative diseases, like Alzheimer's disease, is lower in people who participate in endurance exercise on a regular basis, noted Joshua Yarrow, PhD, lead researcher and postdoctoral associate at the University of Florida in Gainesville.

He and his colleagues evaluated the effect of resistance training, including weightlifting, on levels of circulating neuroprotective molecules like BDNF.

Or, it explains why lazy fatsos are demented. (e.g., see here, here and here)

Either way, train.
