Fig. 2. Representative patterns of swimming velocity and acceleration for frog 6.
(A) Moderate speed swimming. Velocities (top) and accelerations (bottom) for
four consecutive stroke cycles showing increasing velocity and acceleration
digitized from the video sequence of a single trial. (B) Vigorous swimming.
Velocities (top) and accelerations (bottom) for four stroke cycles from a
contrasting trial of the same frog showing a rapid escape stroke followed by
three high velocity strokes. Numbers above each acceleration peak represent
the plantaris muscle mass-specific power output (W kg–1) for
each cycle.
