“This is the first time we have beenable to quantify the preventative potential（听力阅读中常会出现的词-prevent/preventative/prevention预防） of physical activity in terms ofreducing future levels of depression,” said the study’s lead author AssociateProfessor Samuel Harvey, from the Black Dog Institute and UNSW, in a statement.

He said it’s not clear exactly whyexercise is so good for combatting （与..做斗争）depression, but speculated it’s likely because ofthe “combined impact of the various physical and social benefits of physicalactivity”.
