Exercise and Depression

Tuesday, April 13th, 2010

Another benefit of regular exercise: improved mental health.

Exercise is a magic drug for many people with depressionand anxiety disorders, and it should be morewidely prescribed by mental healthcare providers, according to researchers who analyzed the results of numerous published studies.

“Exercise has been shown to have tremendous benefits for mental health,” says Jasper Smits, director of the Anxiety Research and Treatment Program at Southern Methodist University in Dallas. “The more therapists who are trained in exercise therapy, the better off patients will be.”

“Individuals who exercise report fewer symptoms of anxiety and depression, and lower levels of stress and anger,” Smits says. “Exercise appears to affect, like an antidepressant, particular neurotransmitter systems in the brain, and it helps patients with depression re-establish positive behaviors. For patients with anxiety disorders, exercise reduces their fears of fear and related bodily sensations such as a racing heart and rapid breathing.”

Yes, again: the best weight loss comes from lifting heavier, challenging weights. From the NYT:

For people who lift weights to tone up and slim down, experts say, a regimen that includes a combination of challenging weights and fewer repetitions can help significantly. In a 2002 study, for example, scientists looked at what happened when women performed various resistance exercises at different weights and repetitions (85 percent of their maximum ability for 8 reps, versus 45 percent for 15). Subjects lifting more weight fewer times burned more energy and had a greater metabolic boost after exercise.

Toning is not achieved by lifting light weights a bunch of times.  As Dr Oz says, the body is meant to go 60 miles per hour. You can’t keep plugging along at 25mph and expect to lose weight.
