How Backpacks Affect Your Posture

CSEF · 2002 Applied Mechanics/ Structures & Mechanisms/ Manufacturing

Alessandro Castelli, Andrew Earl · Most Holy Trinity Elementary School, San Jose

Overview

Objectives/Goals The purpose for this project is to prove how backpacks affect your posture so that people know that there are risks involved in wearing a backpack. Methods/Materials For this project we used a Roller Backpack and a regular pack using both straps and the same pack using only one strap over just one shoulder. Results The results were that the roller backpack caused the least pain out of all three while wearing the backpack over one shoulder caused the most pain. Conclusions/Discussion Our results ended up being exactly the same as our prediction which proves all backpacks can be dangerous in some way. With everything we have done our conclusion is that people should try roller backpacks.
