Regression coefficients are for joint regression across all individuals. Only the overall mean value is listed for non-significant regressions. F and P values are for the effect of swimming speed, including individual as a random effect. Individual is significant (P<0.05) in all regressions.
^{a}N=275; ^{b}significantly different from 1 (P<0.05); ^{c}not significantly different from 90 (P=0.407).
