The ACOG (American Congress of Obstetricians and Gynecologists) recommends that women get at least 30 minutes of physical activity in daily. Effective movement and exercise on a daily basis has the awesome benefits of increased muscle retention, improved aerobic capacity, and increased maternal comfort. Some Moms have even experienced more comfortable and shorter labors than on average and their babies have been shown to have higher Apgar scores!

How and Why to Exercise During the Prenatal Period

By Rylie Pittard Platt CPT, CSN

Many of us recognize that exercise is a necessary part of life to achieve optimum health, but it is not until recent history that a push has been made to establish a healthy level of activity during pregnancy. In fact, many women are not aware of the benefits that a regular exercise routine can have on pregnancy and labor outcomes. This has resulted in a less than stellar participation rate, with only 1 in 4 women reaching the recommended 30 minutes of moderate exercise daily by the American Congress of Obstetricians and Gynecologists (Newswise, 2012).

Though the introduction of the knowledge of the benefits of exercise during pregnancy may be new to the general public, it is not new to the world of science. Research conducted since the 1980’s has determined that increased muscle retention, improved aerobic capacity, expanded tidal volume, and increased maternal comfort are all positive benefits of exercising during pregnancy (Wang, 1998). In fact, the effects of prenatal exercise have even indicated benefits that supersede that of the mother alone, as some studies have demonstrated improved Apgar (assessment at birth) scores of infants (Morris, 2005). Similarly, women who regularly participate in prenatal fitness on average were found to have experienced shorter and more comfortable labors (Morris, 2005).

Before picking up a regular training routine, it is important to learn how to safely exercise during pregnancy, as there are some very specific factors that are unique to the prenatal period. Maternal core temperature, for example, should remain below 102.6 degree Fahrenheit (Wang, 2005). This can be accomplished by choosing a fitness program that takes place indoors. The rationale behind this is that if the core temperature rises too high (especially during the first trimester), it is theorized that it can have an adverse effect on the development of the fetus (Wang, 1998). Also, the hormone relaxin and increased weight gain of pregnancy lead to joint instability, so all activities involving any rotation about the major joints must be planned carefully as well as specific choices in the weight used during resistance training (). Because of these factors, The American Congress of Obstetricians and Gynecologists recommends engaging in programs that are specifically designed for the prenatal period (Wang, 1998).

A good prenatal fitness class will be held indoors for at least 30 minutes at moderate intensity. Any resistance used should be mild to moderate, which may traditionally include dumbbells and bands with the focus of maintaining muscle mass and to increase cardiac output. It is also important that in picking a class that you determine the instructor or trainer is educated in exercise science as well as versed in those issues specific to the prenatal period.
