Jenna can burn 300 calories per hour on the elliptical trainer and 530 calories per hour on the stair master at moderate intensity. If she works on the elliptical for 45 minutes and on the stair master for one and a half hours, how long will it take her to burn the calories in a Boston Cream Donut?
While most of us know that exercise is smart for our bodies, we don’t always think of the ways exercise benefits our mind. Maybe we don’t need to use the Pythagorean theorem to determine the distance between our bodies and the floor when we do a push-up, but it is important to acknowledge the positive effects that push-up may be having on our mental well-being. Here are some ways to do just that.
The Brain-Exercise Link
John J. Ratey MD and associate professor of psychiatry at Harvard Medical School compares the effects of exercise to “taking a little Prozac or a little Ritalin at just the right moment,” adding, “(Exercise) affects mood, vitality, alertness, and feelings of well-being.”
In fact, MEd Stephen C. Putnam took up canoeing as a way to combat adult ADHD and wrote “Nature’s Ritalin for the Marathon Mind,” a book documenting the benefits of exercise on brain disorders. He cites one study involving children who ran around for 15 to 45 minutes before school and found them to exhibit calm behavior for two to four hours after the exercise, cutting unruly behavior by half.
How Does Exercise Train the Brian
According to Christin Anderson, MS, exercise effects places in the nervous system causing it to send out pleasure chemicals like dopamine and serotonin which leading to happiness and calmness. She says, “When one exercises, one can think more clearly, perform better, and raise morale. This is pure science-stimulate your nervous system and function at a higher level.”
Exercise and Depression
A study cited in the Journal of Sports Medicine and Physical Fitness, tested 80 young female and male volunteers for mood and depression. The 52 that were found to be depressed before the exercise reported a decrease in fatigue, anger, and tension and an increase in vigor following the workout.
Another study done at Duke University compared the effects of exercise with antidepressant drugs. The study involved 150 people, 50 of whom had been diagnosed with depression. These people were divided into three groups, one of which was given the antidepressant, Zoloft, another of which were treated with exercise, and the third of which was given a combination of the two. Results found that while all three experienced short-term improvement, the exercise group relapsed at lower rates than the Zoloft and combination groups. in fact, scientists even felt that the Zoloft may have undermined the effects of the exercise, and the combination group may have faired better without the pill.
Exercise as a Brain Trainer
Do you want to try and use exercise to train your brain? If so, try doing low to moderate forms of exercise, as more intense exercise may have less immediate results. Ratey suggests 8 to 12 minutes of perspiration and heavy breathing activity per day for training the mind.
Anderson recommends a minimum of 30 minutes of moderate exercise such as swimming or walking three times a week. “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.” She also cites yoga as a way to improve mental acuity and meditation as an ideal complement to physical activity.
