Fig. 1. Double logarithmic plot of the net energy cost of human running
(Erun) versus body mass calculated from the slope
method (A) and subtraction method (B) (see Materials and methods for
explanation). The shaded circles represent human data from 20 previously
published sources (see Table 1A
and Table 1B for corresponding
data), and the solid circle represents the mean value from these studies. The
solid line in A and the broken line in B correspond to
Erun predicted from the allometric equation of Taylor et
al. (Taylor et al., 1982)
(Eqn 1). The solid line in B
corresponds to Erun predicted from the new allometric
equation from the present study (Eqn
2).
