The movement profiles of field-based team sports players (e.g., rugby, soccer, and field hockey) fluctuate randomly depending on the game situation, and can include brief periods of high intensity, and longer periods of low intensity, movement. Several studies have investigated the match-play demands of field-based team sports (Gabbett, 2010; King et al., 2009; Mohr et al., 2003; Mohr et al., 2...

Traditional talent development pathways for adolescents in team sports follow talent identification procedures based on subjective games ratings and isolated athletic assessment. Most talent development models are exclusive rather than inclusive in nature. Subsequently, talent identification may result in discontentment, premature stratification, or dropout from team sports. Understanding the m...

We present a graph-based approach to analyzing player interaction in team sports. A simple pass-based representation is presented that is subsequently used together with the PageRank algorithm to identify the importance of the players. Aggregating player scores to team values allows for turning our approach into a predictor of the winning team. We report on empirical results on five German Bund...

Team sports such as ice hockey and basketball involve complex player interactions. Modeling how players interact with each other presents a great challenge to researchers in the ield of sports analysis. The most common source of data available for this type of analysis is player trajectory tracking data, which encode vital information about themotion, action, and intention of players. At an ind...

M usculoskeletal injuries are an integral part of many sports. Contact sports seem to produce the most, with football, hockey, soccer, and basketball leading the way. As athletes compete and push themselves to improve, sprains, strains, contusions, and other injuries become part of the daily routine. Those often attending to these athletes with regular aches and pains are athletic trainers, phy...

The present research studies and compares the effect of participating in team sports (soccer and volleyball) and individual sports (table tennis and badminton) on depression among high school students of Khoramdareh City in the period of 2006-2007. Research method is semi-empirical and the population of the research includes 1300 high school students of which 100 students with depression (rangi...

Professional sports leagues are motivated to promote competitive balance in order to maintain fan interest. The National Football League (NFL) has taken several steps to promote competitive balance, most notably free agency and the salary cap, which were instituted prior to the 1994 season. Previous research into competitive balance in sports focused on the variability of team strengths but ign...

Authors have disagreed on whether sports spectating has positive or negative consequences for individuals and society. Based on Smith's 1988 discussion of "the noble sports fan," the current research tested the prediction that identification with a sports team would be positively related to collective or group's self-esteem and not related to trait scores of aggression. The hypothesis was confi...

Most team sports are characterised by repeated short maximal sprint efforts interspersed with longer periods of active recovery or rest. Although a variety of testing protocols have been devised to simulate these activity patterns under controlled conditions, a common limitation is the lack of 'body contact' to simulate the tackling efforts seen in contact sports. Therefore, the purpose of this...

The Traveling Tournament Problem (TTP) is a wellknown NP-complete problem in sports scheduling that was inspired by the application of optimizing schedules for Major League Baseball to reduce total team travel. The techniques and heuristics from the n-team TTP can be extended to optimize the scheduling of other sports leagues, such as the Nippon Professional Baseball (NPB) league in Japan. In t...
