Some groups of smooth muscles during pregnancy seem to relax. For example, relaxation of the smooth muscles of the arteries is necessary for vasodilatation and pressure reduction - this ensures an increased supply of blood, and with it oxygen and nutrients to the placenta. The smooth muscles of the intestines, in turn, also relax, so that Mommy, and with her baby, gets more nutrients from the food.
Strong changes accompany during pregnancy abdominal muscles - the so-called straight muscles that run from the ribs to the pubic bone. Before pregnancy, the rectus abdominal muscles related to the group of skeletal muscles formed a press, now they support the uterus. Skeletal muscles, and direct abdominal muscles including, during pregnancy are forced to support and move much more weight than before. And if a woman before pregnancy neglected physical exercises, the skeletal muscles of her less elastic, in connection with which the risk of injuries and strains increases. In order to avoid injuries and strains, it is necessary to devote time to special stretching and strength exercises.
During pregnancy, the pelvic floor muscles also experience stress: during pregnancy, they seem to serve as a support for the baby, and if the birth is natural, these muscles take part in "pushing out" the baby. Often, after delivery, the muscles of the pelvic floor are weakened: this can be caused by rupture of the perineal tissues, cutting the perineum for benefit in childbirth. In the future, a decrease in the elasticity of the pelvic floor muscles can cause a decrease in the muscles of the urethra: in this case, a small amount of urine can be spontaneously discharged through it (especially during laughter, cough, and physical exertion). Avoid these problems by resorting to special exercises aimed at strengthening the muscles of the pelvic floor.
Increases the load during pregnancy and on the muscles of the back. The fact is that as the fetus develops, the maternity changes the center of gravity, and hence the habitual position of the body. If the muscles of the back were not strong enough before pregnancy, during bearing the baby in the pregnant woman may have a posture, the back often hurts. The only way out of this situation is the development of the muscular corset even before pregnancy: in the position to swing the back muscles can not be, it is allowed only to maintain them in tone.
It is known that in parallel with the development of the baby in the womb, the weight of the pregnant woman also increases - accordingly, the load on the muscles of the legs increases. There are frequent in the environment of pregnancy the appearance of seizures of gastrocnemius muscles. In order to prevent edema, varicose veins, you can again use gymnastics for pregnant women, which includes exercises for the muscles of the legs. Cramps of gastrocnemius muscles, in turn, occur in pregnant women as a result of a lack of essential vitamins and trace elements - calcium, magnesium, potassium, vitamin D, E and others. At the last stages of pregnancy, in the last trimester, calf muscle cramps can provoke varicose veins or the syndrome of the inferior vena cava.
Speaking about the muscles during pregnancy, you can not forget about the muscles of the chest. During the bearing of the baby, under the influence of hormones and preparing for breastfeeding, the breast increases in size. Accordingly, the load on the pectoral muscles increases. Avoid hanging breasts and keep her shape will help special gymnastics - and preferably perform exercises to strengthen the pectoral muscles before pregnancy.
