Athletes usually shout a word, such as "S-A-! (sa) "S-A-O-! (scanning) "z-a-! (smash)”“S-O-U-！ (whoosh) "Z-O-U-! (punches) ""z-a-o-! (chisel) ""Y-A-! (ah) ""Y-A-O-! (to) "Y-E-! (yeah) "H-A-! (ha) "Y-O-U-! (yes) ""CH-A-O-! (noisy) "CH-OU-! (pumping) "and so on (all syllables end in a falling tone). They are all meaningless monosyllables, and they never have a fixed pronunciation, but they are just shouted by the body at will. The only rule is that these shouts are explosive sounds, which sound like a vigorous sprint and are very exciting. In fact, it is an unwritten custom to make a hullabaloo about on the court during the game. From the national team to sports schools in various provinces and cities, most professional athletes have this habit, because shouting on the field can make athletes enter the competition state as soon as possible. Sometimes the coach will deliberately order the athletes to shout a few times before the game. Marin often uses this trick, which is how he got his "horse roar". This habit is really effective. If you don't believe me, you can try shouting at random during the game.
