Sports relay a great thrill and negative feelings through players and fans alike, although the involved emotion tends to take a greater toll on the former than the latter. Mostly, when a player does a mistake, they usually look so much into it that they end up losing focus and, temper sometimes. Emotions can haunt anyone before, during or after the game and they do manifest in almost every sport.
Emotions have firmly established their place in sport psychology research over the past 40 years. For many decades following World War II, mainstream psychology researchers placed negative emotions (e.g., anxiety) ahead of positive emotions (e.g., happiness) but positive emotions are now a genuine, promising field of research because of their influence on specific components of performance (e.g., attention) and psychological well-being.
