2.2.2 Voluntary Physical Exercise (VPE)
Voluntary physical exercise was performed using a voluntary running
wheel placed inside the cages during the treatment time (varying
according to each group), thus allowing free access by the animals. The
exercise mileage of the animals was controlled through an infrared
equipment placed next to the wheel and was divided by the animals
present in the cage (5 animals)
(Muller et al., 2011). This
analysis was performed in the pre-pregnancy period (8th week) and during
pregnancy (12th week). The females during the pre-pregnancy period ran
an average of 3143 meters/day and in the gestation period 5649m/day, and
this amount traveled was an estimate per animal.
