Maternal body weight, offspring size and weight. a Maternal body weight before as well as during mating and pregnancy did not change upon exercise (n = 9 per group) (a). b–c Both, offspring size (b) and weight (c) from exercising mothers (black bar) was significantly decreased at postnatal day (P) 1 (male and female pups pooled). At weaning (P21), only the weight of the offspring was still decreased (male pups). At P60, no difference in the weight of male offspring was observed (c). Data are presented as mean ± SDM. Open bar: offspring of sedentary mothers. *p < 0.05, ***p < 0.001
