Fig. 2.

Example kinematic data from a Myotis myotis jump. (A) Raw and smoothed positional data of the bat's centre of mass (CoM). Definitions of take-off angle and jump height are also indicated. (B) Velocity of the bat's CoM, including the point taken as representative of the bat's take-off speed. (C) Force acting upon the bat's CoM, including the point taken to be the bat's jump force. All plots are shown with vertical dashed lines to indicate key events in the jump sequence. From left to right, the lines signify the jump start, wrist off the ground and the first downstroke.
