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. gender determination Gender of baby. 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. gender determination Chinese-pregnancy-gender-calender. 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. gender determination Babies. 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.
