Researchers examined 28 healthy children (aged 7 and 11) who were at a normal weight, and found that devoting just three minutes to walking every half hour when sitting for a total of three hours resulted in lower blood sugar and insulin level when compared to a different day when the children were sedentary for the entire three hours.
Researchers also added that the additional activity did not appear to increase the children's appetites.
Of course, this was a very small study, and in order to draw more concrete results, further research would need to be done with a larger sample size. But it's encouraging news at a time when fitting in time to exercise can be a struggle—and an easy thing our kids could do throughout the school day or when doing homework.
