Subjective perceptual methods for comparing backpacks
Article Abstract:
A study compared two backpacks, Pack A from New Zealand and Pack B from the United Kingdom, using two subjective perceptual methods. Ten male subjects carried the 20-kg backpacks during a 30-minute uphill treadmill walk. Category ratio scale (CSR) ratings of discomfort and answers to a written questionnaire indicate that most subjects preferred Pack A due to its good back support, size and fit. Results show that the questionnaire method for distinguishing between backpacks is more effective than the use of CSR ratings of perceived discomfort.

Subjective perceptual methods for comparing backpacks in the field
Article Abstract:
The stability of quantitative and qualitative subjective perceptual approaches is evaluated to distinguish between subtle design differences in two backpacks in a controlled field trial with ten male participants. Findings indicate that qualitative subjective perceptual methods are more useful than the quantitative ones in distinguishing between backpacks and in identifying positive and negative design features.

There were no significant differences between secondary students in respect of number of cycling errors made when traversing an obstacle course as fast as they could with and without bag. However, the children generally took more time to complete the course when carrying the school bag and stopping distances were greater.
