Percentage (%) of taekwondo matches won by athletes according to their color of protectors (blue and red) given different degrees of relative ability (asymmetry) in the two athletes in each match. (a) Male ITA-SC; (b) Female ITA-SC; (c) Male UZB-SC; (d) Female UZB-SC. Black lines at 50% indicate the expected percentage of wins by blue and red under the null hypothesis that the color is not associated with the outcome of the match. χ²: chi-square; * significant association between the color of the protectors and the winning of the match (* p < 0.05; ** p < 0.01); V: Cramer’s V.
