OBJECTIVE To ascertain the reasons behind players not participating in a sports safety research project. METHODS During the preseason, 10 Australian football clubs volunteered 23 teams to participate in a protective equipment randomised controlled trial, the Australian Football Injury Prevention Project (AFIPP). All players from these teams were invited to participate. Players who did not agr...

Although the social exchange paradigm has produced a vibrant research program, the theoretical tradition is rarely used to model the structure of social networks outside of experiments and simulations. To address this limitation, we derive power-dependence predictions about network structure and geographic mobility-the outcomes of power-use-and test these predictions using complete data on comp...

There are a number of sports played across the world under the name football, with most of the world reserving that name for association football or soccer. Soccer is discussed in Chapter 5 of this volume, this chapter considers American football, the basic structure of which is described in the next paragraph. Most of the material in this chapter is discussed in terms of the National Football ...

With the initial issue of this journal, a new challenge has been offered to the world of sports nutrition: initiate "team oriented" research and clinical trials in order to make dynamic progress in terms of understanding and applying nutrition principals to the field of competitive sports. It is our further challenge that these teams think "outside the box" in terms of their approach to elucida...

For professional sports organizations, team names and logos represent a group’s central identity, reflecting geographic location and important attributes pertaining to strength and skill. For minority groups and women, however, team names and logos have also served as a site of oppression in the sports domain. This study examines this problem as it is apparent in team names and logos chosen to ...

Talent finding in sports can not only lead to winning teams but also ensure individuals continue to participate, improve their talents, and take preventive measures against injuries. Athletic talent often develops as the result of morphological, physiological, or psychological characteristics. Many of these characteristics are inherited, and genetics have important implications for talent. Tale...

Professional sports teams receive large public subsidies for new facility construction. Empirical research suggests that these subsidies cannot be justified by tangible or intangible economic benefits. We develop a model of bargaining between local governments and teams over subsidies that includes league expansion decisions. The model features loss aversion by fans that captures lost utility w...

Predicting the outcome of a future game between two sports teams poses a challenging problem of interest to statistical scientists as well as the general public. To be effective such prediction must exploit special contextual features of the game. In this paper, we confront such features and address the need to: (i) use all relevant sample information; (ii) reflect the home game advantage. To d...

This study aimed to test a multilevel mediation model which examined the relationship between the perceived motivational climate created by coaches at team level and motivational regulations towards sport at individual level, as mediated by individual goal orientations. 211 university athletes from 20 teams training in different types of sport completed a battery of instruments that measured th...

In business and sports, teams often experience periods of positive and negative momentum while pursuing their goals. However, researchers have not yet been able to provide insights into how psychological and behavioral states actually change during positive and negative team momentum. In the current study we aimed to provide these insights by introducing an experimental dynamical research desig...
