 Context examples 

In front of them a porter pushes a trolley piled high with trunks, wraps, and gun-cases.

(The Lost World, by Sir Arthur Conan Doyle)

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.

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

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.

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

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)

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.

(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).

Then out into the spring fields, where a yellow trolley raced them for a minute with people in it who might once have seen the pale magic of her face along the casual street.

(The Great Gatsby, by F. Scott Fitzgerald)
