FIGURE 3.

Exercise during pregnancy and lactation lowered fat mass but had no effect on glucose tolerance or thoracic aorta endothelial‐dependent and independent vasodilatation in the dams. (a) Body weight at 15 weeks of age, just prior to exercise; and (b) throughout breeding, pregnancy and lactation. (c) Total body fat percentage at the end of lactation. (d) Fasting blood glucose; (e) intraperitoneal glucose tolerance test; and (f) area under the glucose excursion curve at the end of lactation. (g) Acetylcholine (Ach)‐induced and (h) sodium nitroprusside (SNP)‐induced vasodilatation of aortic rings preconstricted with phenylephrine (10^–5 M) at age 23 weeks. Values for each individual mouse presented; bar graphs represent mean ± SD (n = 8–14/group). For vascular function graphs, data symbols represent mean ± SD. Exe, exercise; Sed, sedentary
