Fig. 7. Hematocrit of female mice from a study reported elsewhere
(Swallow et al., 2005). Mice
were given wheel access for 8 weeks beginning at weaning. Additional mice (not
shown) were housed without access to running wheels, and they showed no
Selected (S) versus Control (C) difference in hematocrit. Thus, S
mice are more responsive (more plastic) when granted wheel access, but not by
virtue of a simple linear relation with amount of running that applies to all
animals. Compare with Fig.
6B.
