 Context examples 

As an overall conclusion, the study corroborates that schoolchildren who use backpacks should avoid carrying loads greater than 10% of their body weight.

(Researchers identify the maximum weight that children should carry in their school backpacks, University of Granada)

Zapata also made one landing on a boat mid-channel to refill the kerosene fuel in his backpack, a process Zapata described as being tricky because the boat could not be kept still in the moving waters of the Channel.

(French inventor Franky Zapata successfully crosses English Channel on jet-powered hoverboard, Wikinews)

However, in Spain, more than 40% of children use backpacks on wheeled trolleys, and until now there have been no studies making weight recommendations for this type of backpack.

To date, weight recommendations have been established for ordinary school backpacks, as they are the most widely used type in the school context worldwide.

Furthermore, in a new finding, when pulling a school backpack trolley, the child should avoid carrying any load greater than 20% of their body weight.

However, pulling the backpack trolley produces fewer changes in the child’s kinematics and, therefore, resembles more closely their movement when walking free of any load, compared to carrying the backpack, even when it weighs very little.

A kinematic analysis of the children (posture of the trunk and lower limbs) was conducted while (i) they walked freely, carrying no weight, (ii) carrying a traditional backpack, and finally (iii) pulling a backpack trolley with different loads (10%, 15%, and 20% of their respective body weights).

(Researchers identify the maximum weight that children should carry in their school backpacks, University of Granada)

Scientists from the University of Granada and Liverpool John Moores University (UK) have established that school children who use backpacks should avoid loads of more than 10% of their body weight—and those who use trolleys, 20% of their body weight.

(Researchers identify the maximum weight that children should carry in their school backpacks, University of Granada)

The main findings of the study indicate that the greatest alterations when using trolleys or backpacks are produced in the proximal extremities (hip and trunk), while there is little difference in the kinematics of the distal extremities (knee and ankle).
