New US research has found that boys who play team sports appear to have larger hippocampal volumes in the brain and fewer symptoms of depression.
Carried out by researchers at Washington University .., along with the University of California and the University of Vermont, the new study looked at 4,191 children age nine to 11 across the US…
The findings.. showed that playing sport was associated with a larger hippocampal volume in both girls and boys, and also fewer symptoms of depression in boys.
The associations were even stronger for children participating in sports that were more structured, such as team sports or regular lessons.
“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,”
The researchers suggested that the different effect of sports on depression among girls could mean that different factors contribute to depression in girls, or that a stronger association between sports and depression might emerge at a later developmental period for girls.
Previous research has already found that depression in adults is associated with shrinkage of the hippocampus, a region of the brain important in memory and response to stress, with some studies suggesting that exercise can also have a positive effect on depression and hippocampal volume in adults…]
