Figure 4. Shift in the optimal angle for maximal voluntary torque and the twitch torque evoked by paired stimuli.

A, over the first 24 h after eccentric exercise, the optimal angle shifted to a significantly longer length for MVC (open bars). The trend for a shift in the twitch was not significant (cross-hatched bars). Optimal angles were the same as pre-exercise values at day 8. B, voluntary torque and twitch evoked by paired stimuli at 90 deg and at the optimal angle. For the MVCs and twitches, there was no significant difference between torque at 90 deg and at the optimal angle at 2 h, day 1 and day 8. All data are shown as the mean ±s.e.m. (n = 8). Asterisks indicate a significant change from pre-exercise values.
