Home advantage in team games is well proven and the influence of the crowd upon officials' decisions has been identified as a plausible cause. The aim of this study was to assess the significance of home advantage for five event groups selected from the Summer Olympic Games between 1896 and 1996, and put home advantage in team games in context with other sports. The five event groups were athletics and weightlifting (predominantly objectively judged), boxing and gymnastics (predominantly subjectively judged) and team games (involving subjective decisions). The proportion of points won was analysed as a binomial response variable using generalized linear interactive modelling. Preliminary exploration of the data highlighted the need to control for the proportion of competitors entered and to split the analysis pre- and post-war. Highly significant home advantage was found in event groups that were either subjectively judged or rely on subjective decisions. In contrast, little or no home advantage (and even away advantage) was observed for the two objectively judged groups. Officiating system was vital to both the existence and extent of home advantage. Our findings suggest that crowd noise has a greater influence upon officials' decisions than players' performances, as events with greater officiating input enjoyed significantly greater home advantage.
OBJECTIVE: To investigate whether the incidence of boxing accidents is higher in Japan than in other countries. METHOD: A nationwide survey of boxers was conducted. RESULTS: A total of 632 boxers responded. Most Japanese boxers were relatively mature when they started boxing (mean starting age of 19.2 years). A high percentage of boxers was found three weight divisions higher than previously reported. Many boxers stated that losing weight was not a big problem. It was found that a punch that turns the head can cause serious physical damage, and it was clarified that only a simple punch, rather than accumulated damage from multiple punches, can cause cerebral concussion. Severe shock causing retrograde amnesia is very rare after a fight and disappears relatively quickly. Many additional symptoms are related to damage to the hearing organs, such as hearing difficulties, tinnitus, and vertigo, but these symptoms also resolve quickly. Many boxers experience memory disturbance, not just after a fight but in daily life. CONCLUSION: The approach to boxing has become more oriented towards the method of practice and scientific training, rather than psychological factors, which used to be emphasised.
