Backpack Single Strap Views
Is there really a major difference between using one and two straps on a backpack? Besides the aesthetic element, there don't seem to be many outward disparities between the two styles. The traditional backpack will always have two straps, simply by virtue of its history as a student favorite. The single strap backpack, on the other hand, is a more recent addition to the fray. It joins such carryalls as the messenger bag in offering students more choices for toting their books, school supplies and other classroom and campus necessities with ease.
A surprising study on the effects of loaded backpacks on lung function yielded some brow-raising results. The 2004 analysis, conducted by the Centre for Ergonomics, Occupation Safety and Health, Department of Human Resources, Massey University in Palmerstown North, New Zealand and the Division of Industrial Ergonomics, Department of Human Work Science, Luleå University of Technology in Luleå, Sweden, focused on carrying loads in both single and double strap styles of backpacks.
Comparing the two types of backpacks, researchers concluded that a backpack carrying a load of 13 pounds could indeed produce a restriction on lung function, however mild. The impairment was found to be greater in individuals who carried a single strap backpack as opposed to the traditional double-harness style.
A backpack with a single strap, also known as a sling bag or a monostrap backpack, is especially popular among students. Individuals who have to carry backpacks for a greater period of time typically opt for a double-harness style because of weight distribution concerns, space (sling bags are generally smaller) and overall practicality.
