The impact of exercise on the fetus
1. Female part of the body anatomy of the fetus during pregnancy when there is appropriate protection of the role of the pelvis, uterine wall and amniotic fluid have a very good shock absorber role, so many pregnant women can safely take part in suitable activities. At early pregnancy, amniotic fluid has the function of lubricating delicate organization, and in late pregnancy, which allow the free movement of the fetus and a slight change in body position.
2. Jumping and physical contact sport of the abdomen of pregnant women vulnerable to shocks, so threatening to the fetus; Other Games all of a sudden the impact of the vagina caused by the flow (such as water-skiing), or changes in pressure (such as diving), this will result in the fetus and the mother’s dangerous, pregnant women should avoid such activities.
3. Exercise for pregnant women, the placental blood and muscle blood sport competition will demand situation of the distribution.
4. Mothers exercise, the decline in pH of arterial blood vessels and reduce the oxygen, the fetal heart rate will increase.
5. In the exercise of the mother, such as ventilation uteroplacental (uteroplacental) is low, the heart rate of fetal anomalies, and heart rate during recovery of the situation there will be too slow. Due to lack of oxygen caused by fetal stress the greater the potential, then the fetus in the mother after the exercise heart rate may become slow restore.
6. A normal fetus, the mother at increased heart rate during exercise and recovery phase gradually decreased.
7. In the exercise will reduce blood flow, but the uterine and umbilical uptake of oxygen remains unchanged, this may be because of fetal hemoglobin to carry oxygen by the mother more than 20% ~ 30%, and maternal fetal blood concentration than 50% . In addition, the fetal demand for oxygen is also reduced, because of its small amount of muscle activity, and fetal body temperature because the liquid to maintain a very stable environment.
8. Exercise should be to avoid “overheating exercise cause fetal disease” (exercise induced fetal hyperthermia), because the symptoms are very dangerous to the fetus.
