Exercise during Pregnancy Avoids Large Baby Born
Exercise in pregnant women can also reduce the risk of obesity later in infants. The average birth weight of infants of mothers who simply doexercise is smaller but very healthy.
The average weight of babies of mothers who exercises are 3.41 kg, compared with infants of mothers who do not exercise which is 3.55 kg.
According to the research team from New Zealand and the United States, infants born weighing 8.8 pounds (3.96 kilograms) or more was defined as a high birth weight.
On a two weeks examination, the babies of mothers who exercise to reach an average weight of 3.68 kg, while infants with mothers who did not exercise was 3.91 kg.
“From this study, we recommend that pregnant wome to do the exercise at least 30 minutes every day or maybe more,” said Paul Hofman, MD, a researcher at the University of Auckland in New Zealand, as reported from webMD, Tuesday (6 / 4 / 2010).
The studies have already been published in the Journal of Clinical Endocrinology & Metabolism, the study 84 pregnant women with first pregnancy and grouping them in the exercise group and control group.
Women in the exercise group rode a bicycle at home with moderate intensity for 40 minutes, a maximum of 5 times a week, beginning at week 20 of pregnancy and continues until about 36 weeks.
The result, babies born to mothers who exercise have lower body weight and body mass index or BMI is also lower.
There was no difference in the length of babies, among women who do not exercise and do the exercises.
“The reason why pregnant women who do exercise gave birth to a small baby is not yet known,” said Chris Baldi, PhD, assistant professor of biological sciences at Northern Arizona University, Flagstaff.
Implications of lower birth weight for mothers who do the exercises as no surprise to Linda May, PhD, a professor of anatomy at the Kansas City University of Medicine and Biosciences in Kansas City, Mo., who is also researching this topic.
According to Linda, with the intensity of exercise recommended for pregnant women brings many benefits. However, further study is needed for high-risk pregnant women.
