ABSTRACT
Sports have taken an ever more prominent position in society. An increasing number of people watch sports events on television and more people see live sports in stadiums and arenas. The economic value of franchises, broadcasting rights, and merchandising has grown. Books on sports appear on the New York Times bestseller list (for example, Lewis, 2004). Besides this increasing interest from the general public, scientists have also taken on sports for their research agenda. Traditionally, research from physiology and medicine has been used to improve performance in sports. Currently researchers from economics, statistics, sociology, and law are working in the sports field.
