Playing Regulations
Games are played in four quarters of 10 (international) or 12 minutes
(NBA). Fifteen minutes are allotted for a half-time break, and two minutes
are allowed at the other breaks. Overtime periods are five minutes long.
Teams exchange baskets for the second half. The time allotted is actual
playing time; the clock is stopped while the play is not active. Therefore,
games generally take much longer to complete than the allotted game time,
typically about two hours.
Five players from each team may be on the court at one time. Teams can
have up to seven substitutes. Substitutions are unlimited but can only
be done when play is stopped. Teams also have a coach, who oversees the
development and strategies of the team, and other team personnel such
as assistant coaches, managers, statisticians, doctors and trainers.
For both men's and women's teams, a standard uniform consists of a pair
of shorts and a tank top with a clearly visible number, unique within
the team, printed on both the front and back. Players wear high-top sneakers
that provide extra ankle support. Typically, team names, players' names
and sometimes sponsors are printed on the uniforms.
A limited number of time-outs, clock stoppages requested by a coach for
a short meeting with the players, are allowed. They generally last no
longer than one minute unless, for televised games, a commercial break
is needed.
The game is controlled by the
officials consisting of the referee, one or two umpires and the table
officials. The table officials are responsible for keeping track of each
teams scoring, timekeeping, individual and team fouls, player substitutions,
team possession arrow, and the shot clock.
