Movement & the Development of Your Brain

New York Times writer Gretchen Reynolds writes, "It's widely accepted among scientists that regular exercise transforms the brain, improving the ability to remember and think." Reynolds goes further pointing to a promising body of research supporting the idea that exercise stimulates the creation of new brain cells, a process called neurogenesis. The National Academy of Sciences published a new study showing how testosterone increases in the brain after training could be fueling neurogenesis and brain plasticity.

It turns out your brain likely produces a significant amount of the hormone dihydrotestosterone or DHT (as you might have guessed by the name, a derivative of testosterone). Researchers found that the hippocampus - critical for memory formation and spacial navigation - in particular was bathed in this hormone after training and that new neuron growth likely resulted from DHT's uptake in the brain. Reynolds summarizes this stating, "In essence, exercise prompts the production of more DHT. And more DHT helps to create more new brain cells."

Turning our attention to brain-derived neuro-tropic factor or BDNF we find yet another body of research supporting brain development and training. BDNF is a protein that promotes tissue growth and health throughout your body, including that brain of yours taking in these words. Training increases your levels of BDNF. It is vital in the learning, memory and higher thinking regions of the brain (not to mention it is well established as an important part of the regulation of body weight, in particular fat oxidation in muscle tissue, and energy homeostasis). Of all the chemicals that help stimulate and control neurogenesis, BDNF is perhaps one of the most active. Harvard's clinical professor of psychiatry Dr. John Ratey calls it the "Miracle-Gro" of the brain.

So, if you happen to be interested in enriching your neurons with the right "nutrients" to fire more quickly, grow faster and develop stronger connections then get into your training, NOW!

Furthermore, I can't think of a more rich neurological climate to pick up meditative or contemplative exercises with the power to yield multifaceted transformations throughout your life. Get training and while you're at it you might as well make strength training your new spiritual practice as Strength To Awaken illustrates.
