The results indicate that weight factor had significantly effect on gait speed, steps per minute, gait cycle time, the ratio of stance time and swing time, maximal flexion angle of knee joint and the range of motion of elbow joint. Shelf height had significantly effects on hip flexion and elbow ROM. Box size factor had significantly effect on stride length, gait cycle time, the ratio of stance time and swing time, knee joint elbow ROM. For the muscle activity levels with EMG, load weight and shelf height both affected the %MVC significantly. When the subjects carrying a load of 14kg, the muscle activity and the subjective body part discomfort rating are both higher than that of 7kg. The box size had effect on the body part discomfort rating of upper extremity and back. For the kinetic and kinematics analysis, the shelf height around elbow height was better than the other two height levels.
