If You Want to Try Exercise as a Brain Trainer continued...
Therefore, low to moderate forms of exercise are recommended for brain training. Ratey recommends 8 to 12 minutes a day of sweating and breathing-hard exercise (60% of maximum heart rate) for brain training.
Anderson says a minimum would be 30 minutes of moderate exercise, walking, hiking, or swimming, three times a week. Half an hour to an hour, four to five times a week would be even better. For those who want to be REALLY on the ball, 90 minutes five to six times a week would not be out of line, she says.
Anderson recommends two sessions a day for this purpose, rather than one big heaving workout. "Swim for 20 minutes in the morning, then walk at night," she advises. "Right after hard, intense exercise, you may not be as acute. Overtraining can set off enzymes that can lead to fatigue, which is the enemy of alertness."
Anderson also says the type of exercise you select depends on your personality. It may be the opposite of what you'd expect. "If you're a 32-year-old male, work 70 hours a week, play ball twice on the weekend and jog daily," she says, "you may need to do some yoga to improve your mental acuity." Some coaches, she points, out actually have to get people to relax to find their "edge." Meditation can also be a great complement to exercise, she adds. Then: "Do what you enjoy. That's important."
"You want to ready your brain for learning," Ratey says. For that to happen, all the chemicals must "jog" into place.
