Until the science matches the scale of complexity and burden posed by depression, our ability to advance knowledge and treatment will continue to be plagued by fragmented, irreproducible mechanistic findings and no guidelines for standards of care.Īmerican Psychiatric Association., American Psychiatric Association. To address the gaps in our understanding of the clinical and molecular effects of exercise on depression, we propose a model that leverages systems biology and multidisciplinary team science with a large-scale public health investment. Regrettably, exercise remains underutilized despite being an accessible, low-cost alternative/adjunctive intervention that can simultaneously reduce depression and improve overall health. Notwithstanding our limited understanding of these effects, clinical evidence uniformly argues for the use of exercise to treat depression. ![]() The complexity of the biological underpinnings of depression coupled with the intricate molecular cascade induced by exercise are significant obstacles in the attempt to disentangle exercise’s effects on depression. However, exercise training has not been demonstrated to consistently modulate such mechanisms, and evidence linking these putative mechanisms and reductions in depression is lacking. Acute bouts of exercise have been shown to transiently modulate circulating levels of serotonin and norepinephrine, brain-derived neurotrophic factor, and a variety of immuno-inflammatory mechanisms in clinical cohorts with depression. Empirical evidence indicates that exercise is effective in treating individuals with depression however, the mechanisms by which exercise exerts anti-depressant effects are not fully understood. Although primarily known for its robust physical health benefits, exercise is increasingly recognized for its mental health and antidepressant benefits. Antidepressant medications have suboptimal outcomes and are too frequently associated with side effects, highlighting the need for alternative treatment options. Levels of Depression according to the BDI:Ġ I am no more worried about my health than usualġ I am worried about physical problems such as aches or pains, or upset stomach, or constipation.Ģ I am very worried about physical problems and it’s hard to think of much else.ģ I am so worried about my physical problems that I cannot think about anything else.Globally, depression is a leading cause of disability and has remained so for decades. The total is obtained when the scores are added for all of the twenty-one questions. The lowest possible score for the whole test is zero. The highest score on each of the twenty-one questions is three (3), the highest possible total for the whole test is sixty-three (63). Each item represents one attitude, such as sadness, pessimism, sense of failure, dissatisfaction, guilt, expectation of punishment, dislike of self, self accusation, suicidal ideation, episodes of crying, irritability, social withdrawal, indecisiveness, change in body image, retardation, insomnia, fatigability, loss of appetite, loss of weight, somatic preoccupation and low level of energy. The BDI is a 21 item self-report rating inventory measuring characteristic attitudes and symptoms of depression. The BDI was revised in 1971 and made copyright in 1978. The original version of the BDI was introduced by Beck, Ward, Mendelson, Mock and Erbaugh in 1961 (cited in Victims’ Web, 2007).
