Scientific Update: Exercise, Mood, and Bipolar Disorder


Exercise is well-known to influence both physical and mental health. The articles reviewed in this post are specific to the impact of exercise on mental health and the symptoms of bipolar disorder. These articles show that people living with bipolar disorder are more likely to be overweight and to have poor eating habits. The implications of these studies is that people living with bipolar disorder must develop good eating habits and a routing habit of physical activity.

Objectives: There have been few comprehensive studies of nutrition and exercise behaviors among patients with bipolar disorder (BPD). Based on a national sample of patients receiving care in the Veterans Affairs (VA) health care system, we compared nutrition and exercise behaviors among individuals diagnosed with BPD, others diagnosed with schizophrenia, and others who did not receive diagnoses of serious mental illness (SMI). Methods: A cross-sectional study of patients who completed the VA's Large Health Survey of Veteran Enrollees section on health and nutrition in fiscal year (FY) 1999 and who either received a diagnosis of BPD (n = 2,032) or schizophrenia (n = 1,895), or were included in a random sample of non-SMI VA patients (n = 3,065). The groups were compared about nutrition and exercise behaviors Results: Patients with BPD were more likely to report poor exercise habits, including infrequent walking or strength exercises than those with no SMI. They were also more likely to self-report suboptimal eating behaviors, including having fewer than two daily meals.

Eriksson, Sebastian, and Gunvor Gard. 2011. "Physical exercise and depression." Physical Therapy Reviews 16, no. 4: 261-268.
Objectives: The objective was to review studies which used physical exercise as an intervention to treat major depression, focusing on methodology, mechanisms of action, types of physical exercise and treatment outcomes. Methods: A literature review from PsycInfo and PubMed databases from 2000-2010 using the key words 'major depression', 'exercise', 'outcome', 'physical activity' and 'aerobic training' as search terms. Results: Eight studies met the inclusion criteria. Seven of the eight studies showed significantly improved mood and reduced depression. Three studies measured an increase in aerobic capacity, two with correlated mood improvements. One showed a correlation between increased muscle strength and reduced feelings of depression. ConclusionPhysical exercise can be an effective treatment against depression. A mood enhancing effect of exercise was identified in the interventions regardless of the mechanism of action.  [Edited from the abstract from the author]
