Expert says that weight should be of 10% to 12% of the body weight of the child
It’s not easy to assemble the backpack of a student: books, book, snacks, clothes. Only the basic items that students bring to school may have a considerable weight to students, which can be harmful in the health of children. Not to cause uncomfortable, according to pediatrician Marcelo Reibscheid, the ideal weight of the backpacks should be between 10% to 12% of the body weight of each child.
— The weight varies with each child. For example, if a student weighs 30 kg bag must have a weight equivalent, that would be between 3.6 kg to 3 kg.
Reibscheid says that the packs should receive special attention from their parents, because with the excessive weight and muscle Contracture may appear in children and adolescents as time.
— By forcing the muscles too can generate pain and back problems such as scoliosis and lordosis. In some cases, to headaches and joint problems of the knee and hips.
An option can be adopted by parents and students: the backpacks with wheels. In addition to being more recommended and considered ideal by the pediatrician, they do not cease to be a preference among children.
But Reibscheid remember: even though bags less harmful and which require less strength of body, should also be proportional measures that correspond to each bone structure.
— The two wheels must run well on any type of floor. As the handles are retractable, they must stay in waist with weight up to 21% in proportion to the student.
If the handle stay below the waist, the student will maintain a posture angle and will ride a pie shape, which can lead to problems in the lumbar spine and dorsal.
