Fig. 1. Swimming kinematics. Shades from white to red represent different swimming
speeds, and shades of blue and green represent different individuals. In A and
B, the boxes are standard statistical box plots, with the box stretching from
the 25th to 75th quartile, which identifies where 50% of the data lie, and a
line at the median. The error bars above and below each box reach to the
maximum or minimum values or 1.5 times the size of the box, whichever is
smaller. Any points that are beyond the length of the error bars are
identified as outliers and shown as separate points. The narrow areas along
the boxes represent approximate 95% confidence intervals. (A) Mean tail
velocity, Utail, equal to 4Af, where A
and f are the tail beat amplitude and frequency, respectively,
against swimming speed (U). Solid line, linear regression; dotted
line, slope of one. Mean Strouhal number (2Af/U) is shown
for each speed. (B) Body wave speed, V, against swimming speed. Solid
line, linear regression; dotted line, slope of one. Slip
(U/V) is shown below each speed. (C) Undulation amplitude,
defined as half the total body excursion at each point along the body at the
four swimming speeds. Thickness of the line represents standard error.
