Psychology underpins crowds and sports performances. An adrenaline rush is common among athletes in encouraging crowds. Social facilitation happens when people do better in groups. Fans cheering for a player or screaming encouragement can increase morale and performance. Hostile or critical spectators can shake even the most experienced athletes’ confidence.

Beyond players, the crowd affects other fans. Research shows that communal applause fosters a sense of solidarity and belonging among onlookers. Witnessing an amazing goal or game-changing moment together enhances emotions and makes the event unforgettable. This unique relationship between athletes, supporters, and their environment makes audience participation important to sports culture.
