Physical activity is important before, during and after pregnancy status.
How do the exercises to a pregnant? Are they necessary? Are favourable to health? What should indicate?
The first thing is to know which are essential before, during and after pregnancy status. The point is how to exercise.
We must understand that pregnancy is a situation hiperdinámica, namely energy expenditure of women are augmented by the intrauterine growth of another being. In addition to cause in her womb, should seek through your body everything needed for their development intrauterine, mainly oxygen and nutrients that are exchanged by the placenta. Thus, their own energy needs, the sum of his pregnant outbreaks.
Such an increase in their metabolism reduces its energy reserves, limiting it to develop exercises in the ceiling, they are also counterproductive.
That in terms of oxygen consumption-a reflection of our exchange-energy, but increases during pregnancy, essentially non-peak. Then, to be increased consumption and kept the basement ceiling, the remaining capacity decreases, and therefore the energy available to dissipate during exercise is lower.
By implication, the maximum yield of low exercise during pregnancy.
The problem arises when the dose of physical effort that involves use of energy in women, which derives its biology part of the energy reserved for the fetus to sustain the needs of metabolic effort. This is called “foetal theft.” And in this measure is that efforts can be very vigorous care for the fetus.
There is evidence that physical exercise produces a comprehensive drop in blood flow and oxygen concentration in the uterine artery, the artery that ultimately takes all the inputs of the fetus.
This phenomenon is caused by hormonal action of the autonomic nervous system (automatic), which derives visceral blood (which goes to the viscera), including the uterus, and redistributed to the muscles.
Despite the potential risk that this involves, oxygen uptake by tissues of the uterus-placenta and fetus remains intact, the one provided by extracting oxygen from hemoglobin fetal blood available.
However, this poses a risk in a pregnancy with a circulation placental limit. It is therefore prudent for pregnant women exercising their bodies in a moderate way.
Also, and especially at the end of pregnancy, exercise can magnify the normal response hipoglicémica increasing uptake of glucose by muscle, which in extreme can affect the supply of glucose to the fetus.
Taking precautions
Another aspect concerns the danger of fetal hyperthermia in the exercise extreme, especially when it’s hot. On the one hand, exercise increases the internal temperature of women-and fetal-and, secondly, the drop in circulation in the uterine sobreesfuerzo prolonged translates into an inability to dispel temperature across the placenta.
That is why it is recommended in warm climates or stations, bringing fresh during the hours of the day, and his caring much hydration.
Another obvious edge refers to avoid a sport or exercise that threatens to direct trauma.
It is not advisable nor take intense exercise programs during pregnancy for a woman who has been sedentary. Of wanting to exercise, should be guided by a specialist, so begin graduate, and not strive ever.
A moderate dose of regular aerobic exercise, 30 to 40 minutes of aerobic exercise intermediate and not beyond the 120 or 130 beats per minute, not necessarily those of the fetus and help maintain a good cardiovascular functional capacity. This coupled with deep breathing exercises and superficial, elongation and flotation (watsu) contribute to the general welfare and have the effect of training for childbirth.
