“Umpires, referees, and sports officials have not been accorded the same attention as athletes by the sports medicine community. The physical and psychological demands of their jobs expose them to a unique constellation of medical, psychological, and orthopedic problems. Read More
Increased aggression during human group contests when competitive ability is more similar.
“Theoretical analyses and empirical studies have revealed that conflict escalation is more likely when individuals are more similar in resource-holding potential (RHP). Conflicts can also occur between groups, but it is unknown whether conflicts also escalate more when groups are more similar in RHP. We tested this hypothesis in humans, using data from two professional sports competitions: football (the Bundesliga, the German first division of football) and basketball (the NBA, the North American National Basketball Association).

“Highly skilled adolescent (15-19 years), young (25-35 years), middle-aged (50-57 years), and older (58-73 years) miniature golf players were examined in training and competitive conditions. Number of shots, heart rate, ratings of anxiety, and concentration time were registered. IN addition, two attentional subscales from the Test of Attentional and Interpersonal Style (TAIS) inventory (Nideffer, 1976) were administered. Read More
Kids speak: preferred parental behavior at youth sport events.
“News reports and scholarly research have indicated increasing concern that parent-spectator behavior at youth sport events may be problematic. Multiple strategies have been used to influence spectator behavior in youth sport contexts (e.g., “Silent Sundays”). However it is unlikely that interventions aimed at changing parent-spectator behaviors have adequately considered young athletes’ perspectives, because little is known about how children want parents to behave during youth sport events.

Get Me Out of This Slump! Visual Illusions Improve Sports Performance
“Misperceiving a target as bigger could influence [sports] performance in one of three ways. It could disrupt performance because the observer might aim for a location that does not correspond with the target. In this case, the misperception would result in worse performance. However, actions and explicit perceptions may not be influenced by illusions to the same degree… In this case, misperceiving a target as bigger would not affect performance. A final alternative is that misperceiving a target as bigger could enhance performance. Bigger targets feel as if they should be easier to hit, so people may feel more confident when aiming for a bigger target. Read More
“Brazil nuts are the second most frequent cause of nut allergy in the United Kingdom. We report the case of a 20-year-old woman with documented Brazil nut allergy who developed widespread urticaria and mild dyspnea after intercourse with her boyfriend who had earlier consumed Brazil nuts. Read More
2. Sport fan identification in obituaries.
“To assess whether sport involvement, particularly as a fan, is central enough to one’s self-concept to be mentioned in obituary content, it was hypothesized that a greater proportion of men’s obituaries than women’s would mention the deceased individual’s sport fan identification.” Read More
“Although learned actions can be automatically elicited in response to expected stimuli for which they have been prepared, little is known about whether learned actions can be automatically initiated by unexpected stimuli. Responses of unwitting participants to balls unexpectedly thrown by an experimenter (n=10) or propelled by a hidden ball cannon (n=22) were recorded by motion capture. Read More
Twice daily collection yields greater semen output and does not affect male libido in the ostrich.
“The success of an artificial insemination program in ostriches is highly dependent on the yield of viable semen. We, therefore, tested how semen output is affected by three different collection frequencies: once every 2d (48h interval), daily (24h interval), and twice a day (6h interval). Ejaculates were collected from seven male ostriches (aged 2-4 years) for 10 consecutive days using the dummy female method. Read More
