Exercise to treat depression

A number of studies in 1990 showed that half of the latest cardiovascular and strength or resistance to mild to severe depression. It turns out that exercise leads to an increase of serotonin, the neurotransmitter that makes us feel good immediately after preparedness, and a long-term change in mood when working regularly once started. These effects are partly due to the strong growth of brain cells. Regular exercise has positive effects onthe immune system, so that can promote health, especially in stressed and / or depressed people.

A study of 12 028 randomly selected people aged 20-79 have shown that increasing physical activity was associated with a 70% reduction in self-reported stress and dissatisfaction decreased life expectancy. Even 2-4 hours per week was associated with significant benefits on foot. Another study by a group of employees showed reductions in stress and depression, and Improvements in feelings of health and vitality compared to a 24 week program of aerobic exercise with a control group. One 1985 study examined 43 patients with depression, about half were treated with antidepressants for the condition. Patients were randomized to receive nine weeks of resistance training (aerobics for an hour three times a week to 50-70% of maximum aerobic capacity) or occupational therapy. Year was statistically significantly greater reduction in place> Depression), as measured by the Beck Depression Inventory (a measure of depressive symptoms. In another study, 86 patients with depression, antidepressants have been treated, but not a therapeutic response were randomized to exercise classes or health education. Exercise loading exercise involved for 45 minutes twice a week for ten weeks of treatment. More patients with exercise had an improvement from an improvement of 30%, measured on a scale forMeasurement of depression called Hamilton Depression Scale (55% more with the practice compared to 33% without a difference that was statistically significant). In another study, 83 patients with major depression experience than aerobic training does not change what they were before. Physical education has been the improvement of depression symptoms improved symptoms of anxiety and not general, but.

Other studies have shown thatimpressive results of the exercise to combat or reduce the symptoms of depression. For example, researchers at the Free University of Berlin also found that 30 minutes a day significantly improved the mood of patients, nine had long suffered from depression months of the move. In a report published in the British Journal of Sports Medicine, 12 patients with depression were 10 weeks of training on the treadmill for 30 minutes a day. There was a statistically significant point of reduction of 6 depressive symptoms, as measured by sales of the Hamilton Depression. The authors concluded, and I agree that exercise could be at least as effective as medication in treating mild to moderate depression.

One study examined 156 patients with major depression for over 50 years, were randomized to aerobic exercise, antidepressants (sertraline) or a combination of both for 16 weeks. All patients showed improvement in symptoms ofDepression> with an essentially identical response between the two groups (1).

A recent report in 2005 described the results of a study of 3 years, designed to test patients at 80 if the exercise is an effective treatment for mild to moderate depressive disorder and to what extent would the people had to be depressed, see a positive difference in the report in the Journal of Preventive Medicine (January 2005) published a half-hour of exercise a day six daysWeek is the ideal "dose" of depression, improve mood of the people who have mild to severe. The researchers compared two groups of depressed patients and found that while the group that 80 minutes was performed weekly movements have little or no mental health benefits (30% reduction with 29% in a placebo exercise "of group) by three hours a week, a significant group (47%) had reduced symptoms.
Exercise can also integrate the effects of antidepressants in depressedPatients. One study movement to antidepressant treatment in 17 patients who had complete response to antidepressants. The exercise has been prescribed according to the guidelines currently recommended by public health – at least 30 minutes of aerobic activity per day – with both meetings under the supervision and home care. There was a 10 point reduction in Hamilton Depression Scale (a clinically significant change) in eight patients who completed the study.

Exercise is verycheaper and more affordable drugs and psychotherapy. Plus has no side effects, such as sexual dysfunction as seen on some antidepressants. In fact, the "side effects" of the use of exercise as an antidepressant positively on general well-being: improving cardiovascular health, increased strength and weight loss.
