The Effect of Exercise on Clinical Depression and Depression Resulting from Mental Illness: A Meta-Analysis

Lynette L. Craft and Daniel M. Landers

The effect of exercise on negative affect has been examined in hundreds of studies. However, the effect of exercise on diagnosed clinical depression has received far less attention. Furthermore, poor methodological techniques predominate and results have been conflicting. A meta-analysis was conducted to investigate the effect of exercise on clinical depression and depression resulting from mental illness. The chosen studies examined the effect of a chronic exercise paradigm (independent variable) on depression (dependent variable). Each study’s variables were coded: design, subjects, exercise, and dependent measure characteristics that could moderate the effect of exercise on depression. Moderator variables were analyzed using analysis of variance (ANOVA). Results from 30 studies showed an overall mean effect of −.72. Therefore, individuals who exercised were −.72 of a standard deviation less depressed than individuals who did not exercise. Moderating variables and implications for the prescription of exercise as an effective treatment for depression are discussed.

Effectiveness of Interventions for Children With Developmental Coordination Disorder in Physical Therapy Contexts: A Systematic Literature Review and Meta-Analysis

Nkechi Offor, Peace Ossom Williamson, and Priscila Caçola


The purpose of this systematic literature review and meta-analysis is to identify the types of interventions in physical therapy contexts that have been explored in children with developmental coordination disorder, the most common variables being addressed, and whether these interventions are effective.


This systematic search of MEDLINE, PEDro, CINAHL, SPORTDiscus, PsycINFO, and Cochrane Library identified interventions in physical therapy contexts for children and adolescents with DCD, and studies were screened using these criteria and assessed using the PEDro and NIH quality assessment scales. AMSTAR was used to evaluate systematic reviews and a meta-analysis was conducted.


From the articles reviewed, 29 articles of moderate to good quality were included in the qualitative analysis. Task-oriented approaches as well as motor skill training–based interventions have shown beneficial effects in improving motor function in children with DCD. Data from 14 articles was extracted for inclusion in the meta-analysis, providing support for the effectiveness of physical therapy interventions against inaction.


Researchers recommend the use of task-oriented and traditional physical therapy interventions for children with DCD. In addition, interventions in physical therapy contexts need clear goals and outcome measures for individual children.
