title: Excess of mixed-footedness among professional soccer players.
abstract: This study concerns the distribution of footedness among professional soccer players (n=415) and nonsporting university students (n=430). Chi-squared showed that there were statistically significant differences between the proportion of mixed-footedness in the two groups (p<.0001). It appears that mixed-footedness or the ability to use both feet with an almost equal consistency is an important factor in the potential of individuals to reach high skill in soccer play. The mixed-footedness of these professional soccer players can be understood best in terms of both the nature of the game and genetic predisposition. This result is of direct interest in the context of those activities in which structural and functional biases in the lower extremities are important variables in acquisition and performance of motor skill.
