Attention!Excess weight in backpack can harm children’s health.
Heavy backpacks can cause serious problems in children
Notebooks, books, handouts, agenda, case. What is not lacking are items of first necessity to be stored in the backpack school. But the question that does not want to remain silent is that everything the child or adolescent takes is ideal for his or her weight?
Physical Education professional Bruno Kirmes explains that the maximum weight loaded by students needs to be 10% of their body weight. “By taking more than it should, the student will begin to project the torso forward or force the abdomen. This can lead to a serious spine problem, with physiological changes in the curvature, and will be especially detrimental in an in-phase child growth, “he explained.
And for anyone who wants to do the math, another tip for the expert. “The calculation of these 10% can not be taken into account when the child is overweight. The right thing to do is to calculate the percentage on your lean mass, which is usually done in physical or nutritional assessments.”
Nowadays, the most usual models of backpack are those more traditional, of handles, and those of wheel. And once the maximum weight allowed for the health of the child or adolescent, and some simple rules, none of them will be harmful to the school routine.
“In the case of the shoulder/back pack, it is ideally proportional to the height of the child (preferably the height of the backpack is the same height as your spine – from the base of the skull to the lower back) . The adjustment of the straps should be made so that the backpack does not pass to the butt area, as this will generate a postural imbalance, and if the backpack has a strap that also holds close to the abdomen, better yet! This is more of a safety factor for the student, “argues Bruno.
Unlike the rucksack, the weight of the wheel does not fall directly on the spine. Still, in the opinion of the Physical Education professional, this option is more harmful because, of course, the child uses only one arm to pull it, which can cause postural imbalance and increase the risk of injury to the arm being overloaded.
“Recalling that these losses will not arise overnight, but with the repetitive process over the years, especially for children and adolescents in the growth phase,” he points out, noting that postural health care should not be limited to backpacks.
Bruno says that in addition to constant concern for the amount of material children are carrying, schools must also constantly assess the ergonomics of school desks, tables, computer screens, drinking fountains and other facilities regularly used by their students.
– When choosing a backpack at Polyhobbies.com, it is important that it is lightweight. When it is empty, it should not weigh more than half a pound.
– Avoid single-strap backpacks – mailbag – because they do not distribute weight evenly, which can also cause posture problems.
– Shoulder straps should be padded, adjustable and at least four centimeters wide at shoulder height. Narrow strips can cause shoulder compression and restrict circulation. It is also interesting to concentrate the heavier objects in the center of the backpack and closer to the back.
– In the case of backpacks with wheels, care must be taken with the handle of the cart, which must be at an appropriate height. The back should be straight as you pull it.
– Parents and guardians should periodically check backpacks to prevent children from carrying unnecessary items. “Often they have things in their backpack that do not need to be taken to school, such as games, toys, tablets, and this adds weight,” warns Bruno Kirmes.
