Figure 6: Shifting of the speed and acceleration just before reaching the maximum speed. Time 0 was the moment of maximum speed. Speed did not gradually increase to the maximum, and mice of all groups showed explosive power in 0.1 s to the maximum speed. Interestingly, acceleration 0.1 s before the maximum speed was under zero and that suggests muscles that were released just before strong contraction.
