Abstract:
Assess the effects of exercise-training on resting arterial pressure and heart rate, placental fetuses morphologic alterations in pregnant spontaneously hypertensive rats (SHRs).Twenty SHRs and their respective control normotensive rats (WKY) were submitted or not to a swimming protocol during 9 weeks, resulting in four pregnant experimental groups: sedentary hypertensive (PSH), trained hypertensive (PTH), sedentary normotensive (PSN), and trained normotensive (PTN). Exercise-training by swimming attenuates arterial pressure in pregnant SHRs, and can contribute to an increase in the length of fetuses and the percentage of the vessels in the placenta.
