Fig. 14. Correlation between dorsal amplitude and upstroke force inclination. (A) Time course of force inclination during the upstroke, shown for the three individuals in Fig. 13. The slope and R² regression statistics for the correlation between dorsal amplitude and force inclination in normalized time intervals of 0.05 for the experimental population are shown at the bottom. Mid-upstroke, defined as a normalized time of 0.55, is indicated by the vertical dotted line. (B) Correlation between dorsal amplitude and mid-upstroke force inclination for the experimental population (R²=0.76).
