Relationships (standardized regression coefficients, b) between relative FA independent of BMI and sprinting speed in 2010 for both 90 m and 180 m sprints.

Sample sizes are as follows: 1996 FA (n = 148 for 90 m, 147 for 180 m); 2006 FA (n = 135 for both sprints); mean of 1996 and 2006 FA (n = 124 for both sprints).Note. Res: Residual; Comp lb-FA: composite lower body fluctuating asymmetry; Statistical significance is indicated by asterisks; r2 values are adjusted for the presence of >1 variable when using multiple regression and apply to the overall model rather than any individual trait.
