Exercise in Pregnancy: Why the Attitude Change?Article By Andrea HowleyMore and more women choose to exercise during pregnancy, although the benefits of exercise in pregnancy remains controversial and research on the subject is still inconclusive at this time. chinese gender prediction Gender selection. Fortunately most experts no longer believe that pregnant women should become complete couch potatoes. Over the past two decades researchers have taken a much closer look at the effects of exercise on pregnant women. The results of these studies suggest that the female body can make amazing adjustments to ensure the health of an unborn baby, even while she is doing strenuous exercise. chinese gender prediction Predict gender of baby. It seems that pregnancy is no longer a reason for women to give up their regular fitness activities. Until the early 1980s there was little scientific information available on this subject. Consequently doctors took a far more conservative, cautious approach to exercise during pregnancy. chinese gender prediction Chinese-gender-calculator. Pregnant exercisers were often told to limit their fitness activities until the baby was born. The major health concerns for pregnant exercisers were:Decreased Blood FlowThe fear of decreased blood flow to the foetus used to be a legitimate concern. Because exercise may direct the flow of blood away from the growing fetus towards the working muscles, many women were advised to keep the heart rate below 140 beats per minute and not to exercise for longer than 15 minutes at a time. But research has shown that a woman's blood volume increases by about 30% during pregnancy to accommodate the fetus. Her heart also pumps more blood per heart beat and blood flows more easily throughout her body. One study found that the cardiovascular system of physically fit women pumped more blood than that of inactive women. Their bodies also used a greater percentage of the oxygen extracted from their blood and this increased oxygen uptake actually keeps the oxygen supply to the fetus reasonably constant!Increased Body TemperatureThere is a higher risk of birth defects when a pregnant woman's internal body temperature rises beyond a certain level. Because of this pregnant exercisers were previously often told to avoid strenuous activities and to limit their training time. Fortunately research has shown that a woman's body develops a far greater ability to get rid of heat when she is pregnant. It is now believed that heat stress experienced by the pregnant woman is reduced by as much as 30% early in pregnancy and by 70% later in pregnancy. Slowed Fetal GrowthThere has also been the concern that regular exercise can slow fetal growth, because blood flow to the fetus may be reduced during strenuous exercise. Studies have now shown that the newly born babies of active woman are slightly lighter, but this difference in weight is actually due to a lower body fat percentage, not retarded growth. Premature LabourUntil a few years ago it was believed that the natural release of certain hormones during strenuous exercise can trigger premature labour. Research has however shown that has no relevance in the case of low-risk pregnancies. Research has been so convincing in recent years that leading authorities has become far less conservative in their guidelines for pregnant exercisers. Moderate exercise 'in the absence of either obstetric or medical complications' is now recommended. Even women who have been completely inactive before there pregnancy may benefit from exercise, as long as they start slowly, progress gently and consult their physician before they start. A woman should always discuss her exercise plans with her doctor and make sure she shows no contraindications for exercise, including incompetent cervix, hypertension, severe vaginal bleeding, previous experiences of premature labour or any signs that the baby's growth is below average. Major fitness goals are definitely not appropriate during pregnancy and realistic expectations are important. Exercise during pregnancy does not guarantee less discomfort, an easier labour or a healthier baby!The goal should be to maintain the highest level of fitness possible during the different stages of pregnany. Safety for the mother and her unborn baby takes should be the first priority.
