In the current study we questioned the impact of uniform color in boxing, taekwondo and wrestling. On 18 photos showing two athletes competing, the hue of each uniform was modified to blue, green or red. For each photo, six color conditions were generated (blue-red, blue-green, green-red and vice versa). In three experiments these 108 photos were randomly presented. Participants (N = 210) had to select the athlete that seemed to be more aggressive, fairer or more likely to win the fight. Results revealed that athletes wearing red in boxing and wrestling were judged more aggressive and more likely to win than athletes wearing blue or green uniforms. In addition, athletes wearing green were judged fairer in boxing and wrestling than athletes wearing red. In taekwondo we did not find any significant impact of uniform color. Results suggest that uniform color in combat sports carries specific meanings that affect others' judgments.
A growing body of research has emphasized the role of facial structures in affecting human social behavior. In particular, the facial width-to-height ratio (fWHR) was found to predict aggressive behavior, most notably in men of low social status. The current study aimed at broadening the insights into the role of fWHR in sports regarding the indicators of aggressive behavior and performance. We questioned the impact of fWHR in association football by analyzing fouls committed by players, their (yellow and red) cards received, and their goals scored and assists in the German (n = 278) and Austrian (n = 194) first division in the 2016–2017 season (306/180 matches). The market values of players were used as a measure of social status. Generalized estimating equation models taking negative binomial distribution into account did not reveal any significant impact of fWHR on fouls committed, yellow and red cards received, or assists and goals scored. Even the consideration of players’ field positions, players’ body mass index (BMI), their market value, and the interactional term of players’ fWHR and players’ market value did not affect the results. The analyses refuted any impact of fWHR in association football both on parameters of aggressive behavior (fouls and cards received) and performance (goals and assists). Merely, players’ market value was found to predict players’ goals and assists. The current study adds to the empirical evidence encouraging a critical assessment and discussion of fWHR research in sports.
Abstract:The impact of feedback on performance turned out to be inconsistent with respect to the significance of a wide range of moderating variables. Concerning personality traits, generalized self-efficacy, self-esteem, locus of control, and emotional stability have been shown to affect the processing of feedba ck. So far, feedback research has observed these traits in isolation, neglecting their interrelations. This study was carried out to investigate the impact of an integrative, higher order concept including these traits (termed as core self-evaluations) on the effects of feedback interventions. Participants (N = 471) received manipulated positive, negative or no feedback (control group) in the scope of two test performances conducted on the computer. Confirmatory factor analysis corroborated the concept of core self-evaluations. Repeated measures ANOVA did not reveal an effect of core self-evaluations on the impact of feedback. Considering the single traits, solely self-esteem turned out to affect the power of feedback.
Past research has documented an impact of sportswear color on performance and referees' judgments in combat and team sports. Amongst other things, it was argued that these effects may arise from differences in visibility. In this regard, the current study was aimed at questioning the impact of uniform color on offside judgments in association football. We analyzed the number of offside judgments for 1530 matches from the first and second division of the football league in Germany and recorded the color of shirts, shorts and stockings for both teams. Data analyses revealed that attacking teams wearing black shirts and black stockings were accompanied by fewer offside decisions. In contrast, defending teams wearing black or green kits were accompanied by increased offside judgments against the opposing teams. Thus, it seems that black and green kits yielded favourable offside judgments. Regarding the low color contrast with green uniforms on a green lawn and the lower detection rate of dark colors the results suggest that green and black kits are less visible, which may impede players' visual detection. The results emphasise the importance of analyzing the role of uniform color in the context of offside decisions to ensure fair play and equal opportunities of winning.

This study examines the influence of wearing and perceiving colors in a cycling setting while also examining cortisol, heart rate, estimated maximum oxygen consumption, and subjective performance ratings. A total of 99 individuals completed the study, consisting of cortisol measurements, which compared baseline values to those after changing into a red or blue outfit, and a maximum cycling task performed wearing the same outfit while competing against a video opponent in red or blue. Each participant completed the protocol twice on separate days. Wearing a colored outfit showed no influence on cortisol levels. Regarding the cycling task, the participants wearing red had higher maximum heart rate values than when wearing blue. In addition, the results revealed increased maximum heart rate and maximum oxygen consumption values when perceiving an opponent in blue, especially when the participant also wore blue. No differences were found for the median heart rate or performance ratings.
Past research has emphasized the role of facial structures in predicting social behavior. In particular the facial width-to-height ratio (fWHR) was found to be a reliable predictor for antisocial and unethical behavior. The current study was aimed at examining this association in the field of sports: FWHRs of 146 doping sanctioned athletes in athletics (37 male/38 female) and weightlifting (44 male/27 female) were compared to the fWHRs of randomly chosen non-doping sanctioned athletes of the Top Ten at the World Championship 2017 and Olympic Games 2016 in both sports (146 athletes). The results showed that doping sanctioned athletes due to the use of anabolic steroids had larger fWHRs than non-doping sanctioned athletes. However, doping sanctioned athletes due to other doping rule violations than the use of anabolic steroids, did not show this effect. The study provides empirical evidence for the relation between fWHR and unethical behavior in a real-world setting and contributes to the discussion about fWHR’s biological origin, emphasizing the role of anabolic steroids. A mutual interaction between fWHR and doping behavior is discussed, at which a larger fWHR might signify a higher tendency to behave unethically, whereas the consequential intake of anabolic steroids might also shape individuals’ faces.
