Boccia 硬地滚球

A match consists of four ends in the individuals and pairs competitions and of six ends in the team division. Each end continues until both teams have played all of their balls.The match is started by throwing the white target ball or the "jack" into the playing area. The same player also rolls the first Boccia ball as close as possible to the jack. The athletes use their hands, feet or an assistive device where required, to propel the balls. Thereafter the opposing team throws until they get a ball closer to the jack or until they have thrown all of their team's balls. Play then returns to the first team. The end continues in this manner until both teams have thrown all of their balls.

硬地滚球比赛时运动员须坐在轮椅上进行投球，得分以投出的球距目标球的距离计算，累积分最高者获胜。单打与双打比赛每场4局，每局单打每个选手投6个球，双打每个选手投3个球。团体比赛共有6局，每局每队3名队员各投2个球。当参赛者因严重的运动能力障碍影响到四肢时，可使用脚或辅助装置将球推出。投球时，辅助设备不得超过投掷线，臀部不能离开轮椅，否则判为罚分或被取消投掷球。
