Sports and recreation consist of a large field of activities, ranging from organized team athletics, such as soccer or basketball, to individual sports, such as bowling, disc golf, or tennis, to recreational activities like swimming or dance. Jobs in the field range from coaching and management positions to instructors and trainers. There are also jobs as competition judges, game officials, umpires, and field or facilities managers. The responsibilities and duties for these jobs vary by position and skill level. For example, a professional baseball umpire needs to complete a rigorous training program, while an umpire for a little league needs less training.
