Fig. 2. Relationship between maximal pectoral girdle muscle power outputs and
strain cycle frequency. Open symbols, adductor profundus; filled symbols,
abductor superficialis. Values are means ± s.e.m. (N=6). The
vertical broken line shows the cycle frequency used during maximal labriform
swimming. The horizontal lines adjacent to each data set show the homogenous
subsets of muscle power output values that span the gait transition (Tukey's
HSD P
0.05).
