Exercise during pregnancy gives newborn brain development a head start

The article mentions a planned follow-up study of the same babies at age 1, but I can't find any published results.

  I'm sure moderate exercise, non polluted oxygen and so forth are helpful at any stage. As all the things we already now (rest, exercise, healthy food, etc.). But I have trouble accepting theories which are based on things that can not be quantified. We'll have to wait 60 years to asses and I'm pretty sure the results will depend mostly on standard-well known facts like family status, family income, schools etc. than the mother doing 'exercise' when the subject was a fetus.

> Women in the exercise group had to perform at least 20 minutes of cardiovascular exercise three times per week at a moderate intensity, which should lead to at least a slight shortness of breath. I find it fascinating that this even qualifies as exercise. An untrained person with a sedentary job will probably just have to climb a few stairs or walk quickly for a few minutes to get this intensity. Who would have thought that healthy activities are.. healthy.

  You missed the "20 minutes" part.

As someone who just became a father (and who's wife exercised during pregnancy), remember that (a) exercise is more difficult when pregnant and (b) anything more than light/moderate exercise is not recommended. My wife was told not to exceed 60% of her max heart rate during exercise. A slightly brisk walk on the treadmill was enough to get her there during the latter portions if the pregnancy. anything that we non-pregnant folk might consider "real exercise" would likely be too strenuous. Now, I'm skeptical as to how accurate those recommendations are, but not enough to disobey them.

  This reminds me of http://www.telegraph.co.uk/news/celebritynews/7871698/Paula-Radcliffe-finishes-10km-charity-run-while-seven-months-pregnant.html http://www.telegraph.co.uk/news/celebritynews/7871698/Paula-... Of course, Paula's pace wasn't race pace, but still... 10km in 45min. It all depends on the women's past exercising habits. You can't ask someone who rarely/never exercises to exercise when pregnant – hence 60% HR of a fit person is not the same as 60% of a non-physically active person.

    I don't care how fit you are, almost no one is running a 10k in 45 minutes at 60% of max HR. I'm sure in many cases more strenuous exercise is not detrimental, but of course the public health recommendations are going to play it safe.

Does this imply that poor village women who work pregnant are producing geniuses?

  Maybe but also if they are poor, any exercise/work along with possible malnourishment could just be more of an exasperation to the underlying nutritional problem.

  Yep. Problem is, there are no schools around.

What's with the spate of press releases from hospitals in Canada recently here on Hacker News? One statement in the press release seems frankly incredible to this father of four children in the United States: "Not so long ago, obstetricians would tell women to take it easy and rest during their pregnancy. Recently, the tides have turned and it is now commonly accepted that inactivity is actually a health concern." What is the definition of "not so long ago" here? My wife exercised (rather more vigorously than what's described in the press release) during all four pregnancies with our children, the first of which was more than twenty years ago. (Our oldest son is now a hacker in New York City.) It would never have occurred to us to do otherwise, and we lived in Seattle, Washington; Minneapolis, Minnesota; and Taipei, Taiwan as our children were expected and born, and in all those places it seemed to be recommended for expectant mothers to exercise during pregnancy. What has changed over twenty years in the United States are weight gain recommendations for pregnant women. As our first son was in utero, the recommended weight gain figures for pregnant women were at the peak that they ever reached. My wife, while exercising moderately but more vigorously than described in the submission here, also dutifully ate far more than she usually eats, and managed to gain up to the full recommended weight gain of that era. Later, the weight gain recommendations were actually revised downwards again. (Whew!) My petite and formerly rather slim wife ends up after four pregnancies with a baseline weight, more than a decade after her last child was born, heavier than she ever was before having children, but still at the low part of the "normal" body mass range for women in the United States, and she still exercises, more vigorously than ever. (She bicycle-commutes year-round here in Minnesota, and we do a lot of our discussion of family business on walks to do grocery shopping or visits to the library that involve us carrying objects home for a mile along our city trail system.) On the whole, I'm rather astonished that as of the date of this press release submission (LUNDI, 11 NOVEMBRE 2013) there could be any controversy in any part of Canada that the kind of exercise described in the article could be anything but beneficial for expectant mothers and their children. How fast does news about better prenatal care spread around the world? I know that the place where we live, Minnesota, is ahead of the world curve in obstetric practice (indeed, my late father was present for my birth and the birth of two of my three siblings, very unusually for that era, beginning in the 1950s), but I didn't think after living in two countries and having children in both that ANYWHERE doubted the benefit of exercise by pregnant women.

The best thing I've read all day. Three days ago my wife have birth to our son, 3.5 weeks early. She's blaming the fact that we were in the middle of a house move for bringing the birth on early. While she wasn't lifting heavy things, the new flat is on the second floor, with no lift, so twenty steps needed to be negotiated regularly. I can now tell her we were simply working on enhanced brain development for our son.
