The Dangers of Sitting for Children
Children that sit too much may face adult-size health consequences. It was found that after a single session of prolonged inactivity, that children developed changes in their blood flow and arteries that in grown-ups would signal the start of serious cardiovascular problems. The dangers of sitting for adults has been well documented recently along with the fact, that exercise does not negate the negative health effects that sitting for prolonged period induce.
It has been found that children are sitting for longer periods of time and that activity levels among kids drop immensely after the age of 8, activity levels continue to fall through their teen years. The decline in activity is most pronounced among girls due to this information, the researchers focused on girls between the ages of 9 to 12. They had 9 participants, 2 of the participants were overweight and the others weights were normal. They observed the vascular function of these young girls as it has been discovered that when we sit for long periods of time, the arteries in our legs stop expanding, they actually constrict. The constriction of our arteries, decreases blood flow, raises blood pressure which over time aids in the development of cardiovascular disease.
The young girls’ vascular function was tests and it was found that all 9 participants had healthy arterial function. Then half of the girls sat in comfortable beanbag chairs for 3 hours, the other girls sat for 3 hours but at the start of each hour, they rode a stationary bike gently for 10 minutes. After the 3 hours, all girls were re-examined. A few days later, all girls repeated the same experiment but changed their experimental condition. Meaning that the girls who previously rode the bike now sat uninterrupted for 3 hours and the girls that sat for 3 hours now rode the bike for 10 minutes at the beginning of every hour.
It was discovered that the girls that sat uninterrupted for 3 hours had a profound reduction in vascular function; their arteries no longer functioned as well. It should be notes that the girls’ arteries returned to normal rapidly after they began to move again. The girls that cycled at the beginning of every hour showed no decline in vascular function. This highlights the importance of movement for people of all ages. Children need to have movement throughout their day just like adults and the Evolution Chair Kit is an easy way to add movement to your day!
