Carrying a heavy school backpack has extensively been reported as a prime cause of children’s body strain.
It is suggested that the load should not exceed 10 percent of the child’s body weight; however, ensuring this requires continuous monitoring.
The study explores how ergonomically designed school backpack based on the user anthropometric data (n=280) and ergonomic parameters help reduce force concentration on shoulders and back.
It provides a validation process of the developed prototype by experimental verification.
The developed design was assessed in a comparison experiment with a commercially available local school backpack.
An experimental study was used which recruited thirty healthy college students (aged 19 to 23 years).
Two independent variables evaluated were school backpack type (developed backpack versus commercial one) and load levels as a percentage of body weight.
Three load levels were employed 10%, 15%, and 20%.
These variables were measured on the responses: bag comfort scale and the percent of maximum voluntary contraction (%MVC) of six muscles (right and left of erector spine, right and left of external abdominal oblique muscle, and right and left of trapezius).
The developed backpack provided astonishing performance at levels of 15% and 20% of body weight in terms of subjective measure and electromyography (EMG) responses.
It also showed that increasing the carried weight more than 10% result in reducing activity on the erector spinal muscles, while it increases on abdominal oblique muscles.
The developed backpack design confirmed the efficiency of its bases by distributing the carried weight among the trunk through side pockets, attached to the body through two upper and lower straps.
It helped the body to distribute the carried weight and avoid concentrating pressure on specific areas.
