Studies confirm that interval training helps improve and maintain good blood flow and delivery of nutrients to the brain. This helps, in turn, to improve and maintain cognitive functioning. This intense type of training - while vigorous - can be accomplished without a huge commitment of time. Interval training twice per week, for about thirty minutes, will suffice. Three times a week, however, is even better. In order to maintain an adequate level of intensity during the interval training session, use of a treadmill, elliptical trainer, or stationary bike is recommended, although I imagine that other methods such as outdoor sprinting would work just as well. Many people don't enjoy working out in a gym. Many do not have the means or the room for large pieces of exercise equipment. A two to three minute warm-up is recommended at the outset of the session, followed by eight, 30-second bursts of high intensity exercise, with 90 seconds of much lower intensity output between each of the eight bursts. Warm down for three to five minutes at the end of the session. Please consult your physician, however, before increasing the intensity of, or changing the nature of, any exercise regimen.
