Sports Have Anti-Depressant Effects

Sports Have Anti-Depressant Effects

Our findings are important because they help illuminate the relationships between involvement in sports, a volume of a particular brain region and depressive symptoms in kids as young as nine," said Lisa Gorham, lead author of the study published in the Journal of Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

We found that involvement in sports, but not non-sport activities such as music or art, is related to greater hippocampal volume in both boys and girls, and is related to reduced depression in boys, Gorham asserted.

These relationships were particularly strong for children participating in sports that involved structure, such as a school team, a non-school league or regular lessons, as compared to more informal engagement in sports, according to the study, which is forthcoming in the journal Biological Psychiatry: Cognitive Neuroscience and Neuroimaging.

The findings raise the intriguing possibility that there is some added benefit of the team or structured components of sports, such as the social interaction or the regularity that these activities provide, said Deanna Barch, senior author on the study.

While other studies have shown the positive impact of exercise on depression and the link with hippocampal volume in adults, this study is among the first to show that participation in team sports may have similar anti-depressant effects in preteen children.

The results indicated that there was an association between sports involvement and hippocampal volume in girls, but unlike boys, no additional association with depression. This might mean that different factors contribute to depression in girls, or that a stronger association to sports involvement might emerge at a later developmental period for girls.
