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