Abstract
A battery of biomechanical tests were used to compare the latest Canadian Forces (CF) backpack with a previously employed model. The primary aim of this study was to assess the utility of the biomechanical approach, the evaluation of CF load carriage equipment was a secondary objective. In the experimental protocol, 12 young men walked for 1.5 hours at 5.54 km/h on a level course, and while stepping over barriers at 3.29 km/h, carrying 32 kg in each of the two backpacks. Measurements included heart rate; electromyographic (EMG) recordings from low back, shoulder and thigh muscles; mechanical energy analysis from cine film; and ratings of perceived exertion. The EMG measures, particularly those from the trapezius muscle proved to be very sensitive to local muscular fatigue. TRUNCATED
