This is interesting. I wonder what the mechanism is that makes pregnant women who did water aerobics less likely to use pain medications during labor. Also, it is very interesting that the control group had more c-sections, even though it was deemed statistically insignificant. I still think it had to play a role in the results of the study.

Ray A.

I wonder why water aerobics was the chosen form of exercise. Is it the safest one? What about walking or yoga or Pilates? Or was it chosen because it seems like the most fun? Also, what are ergometric tests? And why did they have to be performed throughout the study?

Julie

From personal experience, I would say that water aerobics while pregnant is a wonderful way to exercise, and if it decreases labor pain, then even better! While pregnant with my first child, I took a pregnancy swimming class, which was basically water aerobics. There were three of us in class who all had our babies within a two-week time frame, and two of us did not use any pain relievers during labor and delivery.

This study is very interesting. I’m not sure if pain could actually be reduced though, rather the aerobics increased the power of the mind and belief in personal strength. During my classes, we focused and imagined various stages of labor while in the water. I think this helped mentally prepare us for labor and also boosted our confidence in our bodies and the amazing things they can do.

I also wonder if the group that partook in the classes discussed labor and delivery together, and therefore were able to relive some fears they may have had. There are so many factors that could have influenced the results, but I do agree that some type of water therapy while pregnant probably feels really good.

Exercise releases endorphins, which are natural pain relievers. Both endorphins and opioid analgesics bind to the same opiate receptors in the CNS.

Paula B

The authors didn't indicate how long into pregnancy the women maintained the exercise program. Certainly, some women were able to exercise later than others. I hope the authors accounted for this in their results.

Marie

Even though the population size was small, its results are very interesting. I wonder how the water aerobics helped pain management after childbirth. I hope another study is done concerning this topic with more conclusive results!

Eric

Water aerobics is well-known for providing natural resistance with very light to no impact on joints. It is a great way to get your heart pumping without putting strain on joints! This is the first time, however, I have read anything about water aerobics to be associated with pain management. What an interesting article!

Shaily

I'm not sure about this, but I feel like water aerobics would be a safer form of exercise since it's performed in the water and that absorbs shock. I feel like getting on a treadmill or another type of intense exercise would be dangerous to do while pregnant.

Philip

Are there dangers to the mother and baby if you do take pain medications during child labor? I have always wondered about this because some people seem to discourage you from taking any pain relievers, while I haven't heard a lot about the negative effects. Anyone know more about this?

Joselyn

I think exercise during pregnancy is a great idea, but I think you should definitely consult a doctor before starting any exercise program while pregnant. You have to be especially careful of not becoming dehydrated or overheated.

S.k.

I'm not sure if the results of this study are conclusive enough to conclude that water aerobics can directly affect labor pain. There definitely needs to be more research with a bigger subject pool, but I guess exercise never hurts anyone!

Georgia Peters

I’ve got news that may not make the front page, but it’s just as important. Childbirth uses muscles. It’s no coincidence that women who exercise and have practice and control with their muscles have less issues giving childbirth. It was interesting to note that they also required less pain medications and C-sections, which could easily follow from an increased muscle tone and a boost in general health.

Tamara

I think any type of light exercise will benefit pregnant women. Studies show that water aerobics can reduce some of the edema cause by fluid-retention during pregnancy. Women report having less overall physical discomfort, better sleep and improved mobility.

Robert D.

It would be interesting to see these women also have child birth in water to see if there is a synergistic or additive benefit from combining it with water aerobics. Also, subsequent studies need to increase the subject pool (and not the one with water).

Edward N.

Ruth,

Do endorphins have the same effects as opioids? If they bind to the same receptors, then why can athletes still feel pain during exercise? Do marathon runners feel no pain? If someone breaks his/her leg, would running a few miles relieve the pain as effectively as hydrocodone? Is this really the mechanism that water aerobics decreased pain medication use during labor?

shantelle

I have always been a big fan of water exercises! It’s a great way to work out and not put much strain on one’s joints. I think exercising throughout pregnancy has many benefits, and this study proves so!

Myrna Marx

As a follow up to Joselyn's post, the authors note absolute and relative contraindications to exercise during pregnancy as follows: multiple gestation, higher risk of premature labor, incompetent cervix, bleeding during pregnancy, severe heart diseases, fetal growth restriction and others.

Mike

I found it surprising that throughout the pregnancy, the indicators of maternal cardiovascular capacity (e.g., VO2 max, cardiac output) were similar in the two groups. At the same time, they state that the women were exercising at 70 percent of their maximal heart rate. My question is this: how long does it typically take to see an exercise-induced increase in CV capacity?

UncleTony

Hold the phone! What if the water aerobics women were just used to doing things, so they were able to not need pain medication since they were used to "taking the hard road" or just used to being active. My nephew sits on the couch eating sugar-coated butter sticks and does not take out the trash. My other nephew is active in sports, and he does take out the trash without a problem. I think it’s the same idea.

Reese

Georgia, you bring up a great point. It makes sense that exercise would help something as intense on the body as childbirth. I didn't think that exercise could decrease C-sections and pain medications. Hopefully, more research will be done on this.

K.K.

It is great to finally have something besides deep breathing that is not a drug to help reduce delivery pain! Regardless of how beneficial water aerobics is, there must also be significant care to train the mothers to recognize water breakage during these exercises. My pregnant niece unknown to her, broke water during her morning shower which led to a complicated delivery and her infant requiring an antibiotic drip through the cranial soft tissue. Thankfully, both survived a potentially dangerous situation.

Becca

I believe that in general, non-vigorous exercise will benefit pregnant women. Studies do show that women who participate in water aerobics for 50 minutes, three times per week during pregnancy are significantly less likely to ask for pain meds during labor.

Water aerobics is safer for pregnant women than conventional exercise because it decrease edema, prevents an increase in skin temperature and does not overload the musculoskeletal system. Overall, studies show that water aerobics does not negatively affect the mother or her baby’s health and could have some wonderful benefits.

SUMA

I agree with S.K. that the results of this study are not conclusive enough to state that water aerobics helps decrease pain of childbirth. The authors stated “there was no effect on the cardiovascular capacity or on the duration of labor or the type of delivery” between the two groups. I guess I am not clear how they made the association that water aerobics specifically had an effect on analgesia requests. I think there are many confounders that could come into play; for example, pain tolerance, personal views toward delivery, knowledge of the laboring experience and what to expect. (Did they attend childbirth classes?)

I do agree that exercising helps to increase muscle tone which may improve the laboring experience. Water aerobics allows a person to exercise every muscle at the same time. It enhances muscular endurance and improves cardiovascular fitness. The water causes your body to be buoyant, causing less stress on joints and muscles and provides a great deal of resistance in all directions for your muscles to work against. It would be interesting to repeat this study comparing it to other forms of exercise (safe for pregnant women) to determine if the same result is obtained.

liz

I Googled benefits of giving birth in water, and it states that water soothes muscle and stimulates natural pain inhibitors, resulting in less pain/stress or anxiety in the mother. It also mentions that it is less traumatizing for baby since the environment is similar to the womb.

Anna H.

Although well conceived and depicting a hardcore reality of labor pain, this study fails to yield its findings in a sound and scientific manner due to the large number of irregularities in data collection, which was not at all uniform. The high percentage of Caesarian cases in patients who were not subjected to aerobic exercises is a clear indication of their request for analgesics. The results depicted in this study do not indicate scientifically that water aerobics could decrease labor pains.
