If winning is everything, British anthropologists(人类学家)have some advice：Wear red．Their survey of four sports at the 2004 Olympic Games in Athens shows competitors were more 1 to win their contests 2 they wore red uniforms or red body armor．
“Across a 3 of sports, we find that wearing red is consistently associated with a higher probability of winning,”report Russell A．Hill and Robert A．Barton of the University of Durham in England．Their findings are in Thursday's 4 of the journal Nature．
Red is 5 with emotions．When people get 6 , their faces turn red．It’s also a reason why stop signs are red．
7 , the color’s effect may also subconsciously threaten opponents 8 athletic contests, especially when the athletes are 9 in skill and strength, the researchers suggest．
In their 10 , the anthropologists analyzed the results of four combat sports at the summer games：boxing, tae kwon do, Greco-Roman wrestling and freestyle wrestling．
In those 11 , the athletes were randomly(随机地)assigned 12 protective gear and other sportswear．Athletes 13 red gear won more often in 16 of 21 rounds of competition in all four events．
The effect was the same 14 weight classes, too：19 of 29 classes had more red winners, and only four rounds had more blue winners．The red 15 might also come into play in team sports．
The anthropologists analyzed the Euro 2004 International Soccer Tournament, 16 which teams wore jerseys of different colors in different matches．They found that five teams 17 more goals and won more often when they wore shirts that were predominantly red, as 18 to blue or white jerseys．
