In the northern (north east?) part of town there's a huge sport centre where among others are the modern wushu team of China is located. around that place there's all kinds of cheap training gear, some weapons, shoes etc.
If u'r just lookin for sport gear in general I'd check out any of the Wang Fu Jing Street's wearhouses.
