Effects of Body Armor and Load Carriage on Lower Limb Joint Movement
This study investigated the impact of body armor weight and load magnitude and distribution on the lower extremities during walking. Range of motion (ROM) was assessed while seven healthy, male, right-handed, military university students walked while wearing seven different garments of varying weights (0.06 kg, 9 kg, 18 kg, and 27 kg) and load distributions. Decreased pelvic rotation found with...
متن کاملMechanics and energetics of load carriage during human walking.
Although humans clearly expend more energy to walk with an extra load, it is unclear what biomechanical mechanisms contribute to that increase. One possible contribution is the mechanical work performed on the body center of mass (COM), which simple models predict should increase linearly with added mass. The work should be performed primarily by the lower extremity joints, although in unknown ...
متن کاملDynamic analysis of load carriage biomechanics during level walking.
This paper describes an investigation into the biomechanical effects of load carriage dynamics on human locomotion performance. A whole body, inverse dynamics gait model has been developed which uses only kinematic input data to define the gait cycle. To provide input data, three-dimensional gait measurements have been conducted to capture whole body motion while carrying a backpack. A nonlinea...
متن کاملSpatiotemporal Parameters are not Substantially Influenced by Load Carriage or Inclination During Treadmill and Overground Walking
Influences of load carriage and inclination on spatiotemporal parameters were examined during treadmill and overground walking. Ten soldiers walked on a treadmill and overground with three load conditions (00 kg, 20 kg, 40 kg) during level, uphill (6% grade) and downhill (-6% grade) inclinations at self-selected speed, which was constant across conditions. Mean values and standard deviations fo...
متن کاملThe Effects of a Lower Body Exoskeleton Load Carriage Assistive Device on Oxygen Consumption and Kinematics during Walking with Loads
The purpose of this study was to investigate the metabolic cost of wearing a prototype exoskeleton (EXO) while walking with a range of heavy loads, and to analyze the associated gait biomechanics. Ten Army enlisted men participated in the study. Oxygen consumption (VO2) and gait biomechanics were measured while Soldiers walked at 4.83 km/h and 0% grade under three realistic load weight configur...
