Fig. 4. Histograms of time, distance and speed variables in the burst phase and the
coast phase. All the variables, including (A) t1 and
t2, (B) l1 and l2
and (C) v1 and v2, are presented
independently for the two burst-and-coast swimming modes (MT and HT). The
values are plotted as means ± s.d. (N=12).
