What kind of bag is the most suitable

The "burden reduction" of the schoolbag for children has always been a topic of public concern. Do you know that the bag is the most suitable? An article in the American magazine "Life" pointed out that the weight of the backpack should not exceed 10% of the weight of the backpacker.

The American Physical Therapy Association's study of nine grades shows that overweight backpacks and backpacks can cause back injuries and muscle fatigue in adolescents.

Researcher Mary Ann Welsh said that a child's backpack is too heavy to cause kyphosis, scoliosis, forward tilt or distortion.

At the same time, the muscles may be fatigued due to extreme stress, and the neck, shoulders and back are vulnerable. If the weight of the bag exceeds 10%-15% of the weight of the backpacker, the damage to the body will multiply. Therefore, she recommends keeping the weight of the backpack below 10% of the weight of the backpacker.

The American Physical Therapy Association recommends that children use backpacks with shoulders as much as possible. Experts say that the double shoulders can disperse the weight of the backpack, thus reducing the possibility of body distortion.

In addition, the trolley bag is a good choice for younger students, because senior American students often need to go up and down the classroom to change classrooms, while the lower grades do not have these troubles.

In addition, it is important to place the contents of the bag reasonably, with the heaviest items placed close to the back.
