Fig. 11. (A) Forward-directed thrust per foot relative to forward swimming velocity,
with higher thrust and velocity for synchronous kicks relative to asynchronous
kicks. (B) Mass-specific momentum per foot relative to forward velocity and
(C) duration of the power stroke, with the horizontal line in C representing
the approximate average mass-specific momentum per foot for Rana
esculenta calculated from fig.
