Kabaddi

Kabaddi, 12-a-side field pursuit game (only 7 players on each side may take the field at once) very common in Nepal, and also played in India, Pakistan, Myanmar, Sri Lanka, and China. Its most remarkable feature is that players must hold their breath for long periods. It is probably the only field game in the world which has categories for age and weight. Moreover, no equipment is needed and there are no goals. Provided the ground is reasonably level a pitch can be marked on many different kinds of surface.
A match consists of 20-minute halves with a 5-minute interval (15 minute halves for women and juniors). The officials comprise a referee, two umpires, two linesmen, a timekeeper, and a scorer.
In essence it is a highly disciplined form of tag requiring agility and first-class lungs. On taking the field each team occupies its own court. The side that has won the toss sends its first raider into the opponents' court. Before he crosses the centre line he has to start saying kabaddi, and he has to go on saying this word quickly and without drawing breath and loudly enough for everyone within, say, 10 m (32.5 ft), to hear. He continues to do this until his raid is over. This process is called the cant and the object of the raid is to touch as many opponents as possible before returning to one's own court. The raider is obliged to cross his opponent's baulk line at least once and all the time he must keep up his cant. Meanwhile, the opponents try to touch him and also to hem him in to prevent him from returning to his own court.
If the raider manages to cross the baulk line and touch one or more opponents and then manages to get back to his own court without losing his cant (running out of breath), then all the opponents touched are out. If the raider loses his cant while on enemy territory he is out. He is also out if he is touched. A player who is out goes to the waiting block. Each time a team puts a player out they score a point. If a team puts out the whole of the opposition they score a lona (a bonus of 4 points). The team with the most points at the end of 40 minutes wins.
