Cheerleading "Cheerleading" and "Cheerleading" are written, which can be seen in previous works.
At present, authoritative reference books generally recommend the writing of Cheerleading. So "Cheerleading" is a standard word form and should be adopted. "Cheerleading" refers to "organized spectators who cheer for the players in competitive competitions".
English original intention
Cheer literally means encouraging and cheering, but it means cheering when used in competitions (the slogan in China is cheering), which can boost morale and inspire people.
Cheerleading, called "Cheerleading" in English, refers to the group that cheers for the competition, so cheerleading is a group activity.
Cheerleading appears as a team, combining dancing, slogans and partner stunts. It refers to the difficult movements and skills of lifting, combined with music, clothing, formation changes and signs (such as colored balls, placards, horns and flags), and abides by the rules of the game about gender, number of people, time limit and safety rules. It's called competitive cheerleading, or cheerleading.
