This article presents a novel model for evaluating the performance of field players in football. Based upon Data Envelopment Analysis (DEA), we employ a nonconcave metafrontier approach that permits estimation of players’ efficiency scores under consideration of their playing positions. The model is applied to a data set of Germany’s premier league football players covering the playing seasons ...

In this study we investigate the recently introduced competition format for the top association football division in Poland (similar to one used in, e.g., Belgium and Kazakhstan). We compare it to the double round-robin tournament which is the most prevalent league format among European leagues. In a simulation study we show that the new league format has better ability to determine the stronge...

Numerous investigations have attested to the efficacy of the National Football League (NFL)-225 test to estimate one repetition maximum (1RM) bench press. However, no studies have assessed the efficacy of the test to track changes in strength across a training program. The purpose of this study was to determine the accuracy of the NFL-225 test for determining the change in 1RM bench press in Na...

Alcohol use and alcohol-related problems, including accidents, vandalism and violence, at sporting events are of increased concern in Sweden and other countries. The relationship between alcohol use and violence has been established and can be explained by the level of intoxication. Given the occurrence of alcohol use and alcohol-related problems at sporting events, research has assessed intoxi...

In this paper, we introduce an R software package for simulating plays and drives using play-by-play data from the National Football League. The simulations are generated by sampling previous football seasons. procedure adds statistical rigor to any decisions or inferences arising examining simulations. We highlight that is particularly useful as a data-driven tool evaluating potential in-game ...

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 ...

Introduction. The aim of the study was to determine the causal attributions of success and failure in a football match in a group of football players, as well as to investigate the association of the players’ attributions with their level of achievement and the relationships between their causal attributions and affective states. Material and methods. The study involved 75 football players, inc...

Twitter has been proven to be a notable source for predictive modeling on various domains such as the stock market, the dissemination of diseases or sports outcomes. However, such a study has not been conducted in football (soccer) so far. The purpose of this research was to study whether data mined from Twitter can be used for this purpose. We built a set of predictive models for the outcome o...

Despite the prominence of professional football in U.S. culture, little research has been conducted examining the social construction of race in the game. People have a cultural perception of race; what effect does this perception have on the players? There has been research on the historical struggles of Black athletes in collegiate football, as well as lasting issues of racism. To add to this...

Fifth metatarsal fractures (5MtF) are one of the most common traumatic foot injuries in football player [1,2]. A previous study demonstrated that the 5MtF in football players occur frequently in their non-dominant limb [2]. Since different playing positions requires different physical demands in match-play [3], the aim of this study was to examine the hypothesis that the limb dominance for 5MtF...
