Finally, we know why Canadian children are less productive than children from other countries. It’s because they have lazy bones. These teens do nothing more than tapping at their laptops or swiping on their tabs or smart phones.
A new research carried out by University of British Columbia warns people about the “four-year window”.
This window tells that girls of age 10 to 14 and boys 12 to 16 have approximately four years, where they need to be more active. During this time period, 36% of the bones in the human skeleton are formed. Teens who are less active during this age bracket are more likely to develop lazy bones, which might break as they grow old.
UBC medicine professor, Dr. Heather McKay was the one leading the study and found out that teens not doing any kind of exercise or strenuous activity were more likely to develop brittle bones.
According to her findings, “The things you do around adolescence to build your bone strength can never be repeated”.
Leigh Gabel, who is a PHD candidate, worked alongside Dr. McKay and looked over the bone health and exercise habits of 309 teenagers. The study lasted for four years and the results were compared by using 3D high resolution X-ray images. The comparison was carried out between teens who were involved with physical activity regularly as per recommendations and teens who did less than thirty minutes of exercise in a day.
According to Dr. McKay, there have been no studies carried out on the bone health of adolescents. On the other hand, studies carried on elderly people with frail bones suggest that they might have been less active when they were teenagers.
The physical activity daily guidelines call for 150 minutes of exercise in a week. The study revealed that around 43% of boys were getting the right amount of exercise and 11% of girls were meeting the target completely. What’s more is that boys are more prone to breaking bones, whereas women have a high chance of developing Osteoporosis.
McKay says that teens should indulge in activities like soccer, basketball and Frisbee. Furthermore, there’s good news adults who want to build bone strength now. They can still keep their skeletal structure intact with regular exercise.
