Fig. 10. Matching the fast-start to the desired take-off speed. For both predictive starts (red) and escapes (blue) take-off speed (defined as average speed within the first 20 ms subsequent to end of stage 2) correlated best with the rate of straightening during stage 2. This rate is taken as the maximum slope dCL/dt in stage 2. Slope and intercept of the regression lines (predictive starts: r²=0.216, P<0.0001, N=76; escapes: r²=0.484, P<0.0001, N=34) did not differ significantly between escapes and predictive starts (P>0.05).
