Hormonal changes during pregnancy The hormonal and physiological changes that come with pregnancy are unique. Pregnant women experience sudden and dramatic increases in estrogen and progesterone.
They also experience changes in the amount and function of a number of other hormones. A woman will produce more estrogen during one pregnancy than throughout her entire life when not pregnant. The increase in estrogen during pregnancy enables the uterus and placenta to: Estrogen levels increase steadily during pregnancy and reach their peak in the third trimester.
The rapid increase in estrogen levels during the first trimester may cause some of the nausea associated with pregnancy. During the second trimesterit plays a major role in the milk duct development that enlarges the breasts.
Progesterone levels also are extraordinarily high during pregnancy. The changes in progesterone cause a laxity or loosening of ligaments and joints throughout the body.
In addition, high levels of progesterone cause internal structures to increase in size, such as the ureters. The ureters connect the kidneys with the maternal bladder. Progesterone is also important for transforming the uterus from the size of a small pear — in its non-pregnant state — to a uterus that can accommodate a full-term baby.
Pregnancy hormones and exercise injuries While these hormones are absolutely critical for a successful pregnancy, they also can make exercise more difficult. Because the ligaments are looser, pregnant women may be at greater risk for sprains and strains of the ankle or knee.
However, no studies have documented an increased rate in injury during pregnancy. Her breasts are larger. Her abdomen transforms from flat or concave to very convex, increasing the curvature of her back.
The combined effect shifts the center of gravity forward and may lead to changes in her sense of balance. Weight gain, fluid retention, and physical activity Weight gain in pregnant women increases the workload on the body from any physical activity.
This additional weight and gravity slow down the circulation of blood and bodily fluids, particularly in the lower limbs. As a result, pregnant women retain fluids and experience swelling of the face and limbs.
This water weight adds another limitation on exercise.
