Why is たform used before 方?


I found this sentence on the Bunpro website and I found it very confusing.

> 疲れている割には、かなり動けた方だと思います

My understanding of this sentence is something like "Despite being tired, I
think (person) is more on the side of being able to move"

Why doesn't it say 動ける方だと思います?

Is this related to the construction "た方がいい"?




The た-form is used simply because the person _was_ able to move on some
concrete occasion such as a sports match.

If the sentence were describing the person's permanent quality as you supposed
it did, it would say 動ける方.
