Exercise and Pregnancy
Sport and gymnastics for pregnant women
During pregnancy significant changes occur muscle-skeletal systems, cardiovascular, respiratory, endocrine and metabolic systems to maintain a normal and optimal functioning of both the pregnant and the fetus.
It recognized the importance of physical activity in humans for the maintenance of optimal health, the pregnant woman is excluded from these benefits. Given the normal changes of pregnancy, as well as those that occurred during exercise in pregnant women have an impact on different body systems.
Muscle-Skeletal System
Several changes occur, the production of hormones and weight gain, causing changes in the ligaments and joint mobility, to maintain and coordinate the center of gravity of the pregnant woman. Occurs a gradual increase in lumbar lordosis and pelvic rotation on the femur, thereby preventing a woman to go forward. As the balance becomes more difficult, especially when walking, it is necessary that your gear is more basic, with a shorter stride and more varied. Therefore, we recommend a strengthening abdominal muscles to control the degree of lumbar curvature. It is also recommended to stretch the extensor muscles of the abdomen and hip (hamstrings) with alternating relaxation and contraction in erector spinae muscles (iliopsoas) and hip flexors (rectus femoris).
Effect on Uterine Activity
Has been reported to moderate exercise in pregnancy can trigger uterine contractions, which have been linked to increased? catecholamine concentration and type of exercise that is practiced. It has been observed that the exercise in a standing position can exert more pressure on the cervix, uterine activity increased by a reflex mechanism, unlike what happened with exercise bike. If contractions persist after exercise should be consulted obstetricians.
