Psychology of Performance – 34: Spark!

The book, Spark, by John J. Ratey, M.D. is the holy grail of research applications related to the interaction of exercise, neuroplasticity, and performance. The information on brain chemistry changes in the areas of learning, addictions, anxiety, depression, women’s issues, ADHD, and aging is priceless. The essence of the book is that the data indicated the brain is able to create new neuronal connections, grow new nerve cells throughout life, manage major psychological conditions, pain conditions, and learning is significantly enhanced through exercise. Ratey stated that “exercise is the single most powerful tool you have to optimize your brain function”- based on hundreds of research studies (p.245). Ratey suggested that the more fit you get (regardless of where you start), the “ more resilient your brain becomes and the better it functions both cognitively and psychologically. If you get your body in shape, your mind will follow” (p. 247).

How much is enough? Ratey stated that walking is enough. Low-intensity exercise is at 55 to 65% of maximum heart rate, moderate is 65-75% and high intensity is 75-90%. “The process of getting fit is all about building up your aerobic base” (p.251). Ratey goes on to discuss the role of strength training and flexibility as important elements of optimizing your brain chemistry and hormone levels.

What does this have to do with optimizing your performance at work and in all areas of your life? Everything! Get started today and stick with it.

Have a day filled with optimal brain chemistry,
