Exercise tolerance is reduced in bipolar illness

Bipolar disorder and leisure-time physical activity: Results from a national survey of Canadians

“…Our results agree with those of Strö hle et al (2007) who found no differences in PA between people with and without BD in a younger sample. In contrast, our results are at odds with the findings from reports using clinical samples (e.g., Elmslie et al, 2001;Shah et al, 2007), and the epidemiological study by Kilbourne et al (2007), who found that older adults with BD engaged in less walking or strengthening exercises than individuals with schizophrenia or without SMI. One explanation for these conflicting results concerns sample selection.…”

“…Elmslie, Mann, Silverstone, Williams, and Romans (2001) found that patients with BD reported fewer episodes of PA than did a sample drawn from the general population. In another study, Shah et al (2007) suggested that patients with BD may be at greater risk for poor physical fitness, possibly because of reduced tolerance for exercise, which would suggest PA levels are also likely to be low in this population. With regard to population-based studies, we could locate only two recent epidemiological studies, the results of which are conflicting.…”

Major Depressive Disorder and Bipolar Disorder Predispose Youth to Accelerated Atherosclerosis and Early Cardiovascular Disease

“…[183][184][185] The association of physical activity with BD is inconsistent. Some studies have demonstrated reduced physical activity and reduced exercise tolerance in BD, 186,187 whereas other studies have demonstrated no significant differences. 188 Although many studies have been cross-sectional, and thus, the relationship may not be causal, prospective data from the National Health and Nutritional Examination Survey I demonstrated that physical inactivity was a significant predictor of the development of depressive symptoms in white women.…”

The effects of physical activity on physical and mental health among individuals with bipolar disorder: A systematic review

“…Hays and colleagues found significant increases in both DHEAS level and self-reported wellbeing post exercise, but no significant correlation between the degree of change in the two variables. Shah et al (2007) tested 14 individuals with euthymic Bipolar I Disorder and 10 individuals with no self-reported history of mood disorder or psychosis. The intervention was treadmill-based exercise at 70% maximum predicted oxygen consumption, continued until exhaustion.…”
