Table 1.

Univariate linear regression results of three predictors (BMI, height and mass) each individually tested against one response (log(event distance)) for analyses of four datasets (men's and women's running and swimming). β indicates the β coefficient, which is the increase in the response variable (log event distance) for every 1-unit change in the predictor variable. Italic p-values are significant.
