Fig. 7. The effect of high strain on the phase shifts between measured and
estimated strain during induced fast-starts for the anterior (0.4FL)
and posterior (0.7FL) locations. Stronger escapes (11 trials, four
individuals), which experience an average strain between the anterior and
posterior position greater than 12.3%, are represented by black open circles
and average phase shifts are represented by horizontal black bars. Weaker
escapes (nine trials, four individuals), less than 12.3% average strain, are
shown by gray-filled circles and average phase shifts are represented by
horizontal gray bars. High strain significantly increases the average phase
shift from 0.005±0.005 s to 0.021±0.009 s at 0.7L
(Mann-Whitney U-test, P<0.005).
