The purpose of this project was to begin the research and development process for an Advanced Personal Load Carriage System (APLCS) for the Canadian Land Forces. This entailed reviewing relevant literature, developing a comprehensive measurement system, providing design guidelines, and a state-of-the-art design. A biomechanical approach was developed so the human input about comfort, features, and fit were appraised as well as standardized load carriage (LC) simulator assessments of design features and functions. Human performance evaluations were based on a mobility circuit which was designed to simulate survival skills. Twenty soldiers appraised their agility, load control, and confort while testing three military systems, and one external frame civilian pack. These same PLCS were worn by 20 soldiers during an extended 6 km march while carrying 32 kg to replicate marching order. Strap forces, body lean, and regions of discomfort were assessed to compare subjective responses with biomechanical and LC simulator findings. The LC simulator consisted of computer controlled pneumatic actuators programmed to cause the motion of a mannikin to replicate military marching. Each LC was mounted on the mannikin such that x and y ground reaction forces were zero. Shoulder straps and the hip belt were tensioned to correspond to human testing conditions. TRUNCATED
