Exercise during pregnancy gives newborn brain development a head start

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.
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'm sure in many cases more strenuous exercise is not detrimental, but of course the public health recommendations are going to play it safe.
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.
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.
AFTER EDIT: I'll add here some links to official statements about exercise for pregnant women.

More seriously, in Arizona I have had friends that were pregnant told to "take it easy" and "don't lift more than 10 pounds" but for the most part the advice is that exercise is good. Usually instructions to avoid exercise are only given when the doctors fear losing the baby due to some other complications.
I think the article and paper, as some scientists have a tendency to do, went overboard when making the case for why this research was needed.
Another field with a similar level of changes is the diets and nutrition recommendations. Are eggs good or bad for you???
