ACE, the American Council on Exercise, has just released the (surprising!) results from a new study that measured the health benefits of fitness walking with your baby in a stroller. Research concludes that the intensity of the activity is almost double than previously assumed, which is great news for new moms everywhere.



Funded by ACE, researchers at the University of Wisconsin enrolled 15 physically active women, ages 19 to 41 into the study. To establish a fitness baseline, all of the women were given a maximal exercise test on a treadmill that measured their oxygen usage, heart rate, and levels of perceived exertion. The women were then given two exercise test sessions while pushing a baby in a stroller.

During the first stroller workout, women walked on a treadmill at 3 mph for 20 minutes, with the strollers weighted to 35 pounds (to mimic a one-year-old baby and diaper bag). Every four minutes the incline was adjusted from flat, to 2.5%, to 5%, and to 7.5% grade. The second test session used the same protocol but at the increased speed of 3.5 mph. Participants heart rates, oxygen usage, and rate of perceived exertion were measured throughout both tests.

While it came as no surprise that walking with a stroller burned more calories than walking alone, or that an increase in the speed and/or incline upped the work load, what surprised researchers was the extent of the difference. They discovered that walking with a stroller burned approximately 18 to 20% more calories than fitness walking alone. At that rate, the average woman would burn about 375 to 440 calories per houran intensity rate of 4 an 5 METSwhich is equivalent to riding a bicycle at 10 mph. (MET values are used to gauge exercise intensity and allow for comparison of different types of activities.)

Previous estimates, as sited by The Compendium of Physical Activity, evaluated walking with a stroller at 2.5 METS, or about half the intensity that the current study has documented.

To maintain or improve health, it's recommended that people perform regular aerobic exercise at a moderate intensity level, and this study confirms that fitness walking with you baby in a stroller meets those goals. Stroller based exercise programs like Baby Boot Camp or Stroller Strides, which incorporate strength and flexibility exercises into their workouts, can provide even greater health benefits. Given the new mother's hectic lifestyle, stroller fitness walking is an easy, economical, and fun way to improve health, lose weight, and connect with other new moms at the same time.
