The sports arena is a football field bordered by a circular track and field track. Places for jumping and throwing balls are located in sectors of the tracks or beyond the outer perimeter of its straight sections. Outdoors, football and athletics are combined on one common structure for them - a football and athletics sports arena. Training sessions in both football and athletics are possible on the sports arena, and when arranged along one or more sides of the sports arena of the rostrum, competitions are possible for spectators.

When designing open sports facilities, it is necessary to strictly observe the orientation of the longitudinal axis of the field of the sports arena and stadium, as well as the grounds for sports games from south to north. The deviation cannot exceed, as a rule, 15° on each side.

The construction of the fields and places for athletics depends on the selected top layer (coating), which can be artificial (from various materials) or grass.

634

Artificial coatings are divided into non-rigid (nonwater resistant, water resistant, new types of seamless elastic and durable coatings), rigid (asphalt coating, concrete coating, porous concrete coating) and wooden. Special coatings (including synthetic materials) of open flat sports facilities must have an even and non-slip surface, which does not lose load capacity during overwetting.

The grass coatings may have:

-specially created sports lawn;

-natural grass cover.
