When fencing, one does not have a "mat" underfoot. Instead, there is a strip, or a "piste". This strip is always marked out when fencing, and in official competitions will be metal and grounded so as fencers are unable to score touches by hitting the floor.
The long rectangular strip is called a piste.

The target area depends on the weapon that you are using. If you are fencing Epee, the target area is your opponent's entire body.

This excludes their legs, arms, and head, limiting it to the chest and stomach region.
