KOMPAS.com - 羽毛球运动于 19 世纪末在英国被发现后,成功传播到世界各地,包括印度尼西亚。
羽毛球比赛至少需要两到四名球员,每人轮流将羽毛球击向对方的比赛区域以得分。
从参赛人数来看,羽毛球运动分为单打和双打两种比赛形式。
除参赛人数外,羽毛球单打或双打比赛也有区别,具体如下:
羽毛球队中两名球员作为双打选手的存在,无疑使得比赛的过程与单打有所不同。
更明确地说,羽毛球比赛中双打运动员的位置可以是平行的侧面,也可以是其中一人在另一名运动员的后面。
羽毛球双打比赛的站位规定是根据比赛策略,即进攻时或防守时来确定的。

羽毛球双打比赛的初始击球或发球系统也与单打比赛有所不同。
正如Tri Hadi Karyono所著的《了解羽毛球运动》(2020年)一书中所引用的那样,羽毛球双打比赛中发球者和发球者有六点规则。
羽毛球双打比赛的六分发球规则是:
发球后,每位选手有权轮流击球,直至比赛停止或两对球队中的一方得分。
如果仔细观察,双打和单打发球的使用略有不同。
羽毛球双打比赛中常用的发球方式是短发球。与此同时,单打更常使用长发球,尤其是女单。
羽毛球双打比赛的比赛场地面积与单打比赛的比赛场地面积是通过球场上的线来区分的。
羽毛球双打比赛,双方比赛场地均采用最后面界线和场地最外侧。

同样,双打发球区也使用最近的发球线,距离球网 1.98 米。
羽毛球双打比赛发球区尺寸为宽3.05米,长3.96米。
